- -
- Installing or Accessing the Neon Eclipse Yocto Plug-in - - - You can install the Eclipse Yocto Plug-in into the Eclipse - IDE one of two ways: use the Yocto Project's Eclipse - Update site to install the pre-built plug-in or build and - install the plug-in from the latest source code. - - -
- Installing the Pre-built Plug-in from the Yocto Project Eclipse Update Site - - - To install the Neon Eclipse Yocto Plug-in from the update - site, follow these steps: - - Start up the Eclipse IDE. - - In Eclipse, select "Install New - Software" from the "Help" menu. - - Click "Add..." in the "Work with:" - area. - - Enter - &ECLIPSE_DL_PLUGIN_URL;/neon - in the URL field and provide a meaningful name - in the "Name" field. - - - Click "OK" to have the entry automatically - populate the "Work with:" field and to have - the items for installation appear in the window - below. - - Check the boxes next to the following: - - Yocto Project SDK Plug-in - Yocto Project Documentation plug-in - - - Complete the remaining software - installation steps and then restart the Eclipse - IDE to finish the installation of the plug-in. - - You can click "OK" when prompted about - installing software that contains unsigned - content. - - - - -
- -
- Installing the Plug-in Using the Latest Source Code - - - To install the Neon Eclipse Yocto Plug-in from the latest - source code, follow these steps: - - - Be sure your build host has JDK version 1.8 - or greater. - On a Linux build host you can determine the - version using the following command: - - $ java -version - - - install X11-related packages: - - $ sudo apt-get install xauth - - - In a new terminal shell, create a Git - repository with: - - $ cd ~ - $ git clone git://git.yoctoproject.org/eclipse-yocto - - - - Use Git to create the correct tag: - - $ cd ~/eclipse-yocto - $ git checkout -b neon/&DISTRO_NAME_NO_CAP; remotes/origin/neon/&DISTRO_NAME_NO_CAP; - - This creates a local tag named - neon/&DISTRO_NAME_NO_CAP; - based on the branch - origin/neon/&DISTRO_NAME_NO_CAP;. - You are put into a detached HEAD state, - which is fine since you are only going to - be building and not developing. - - Change to the - scripts - directory within the Git repository: - - $ cd scripts - - - Set up the local build environment - by running the setup script: - - $ ./setup.sh - - When the script finishes execution, - it prompts you with instructions on how to run - the build.sh script, which - is also in the scripts - directory of the Git repository created - earlier. - - - Run the build.sh - script as directed. - Be sure to provide the tag name, - documentation branch, and a release name. - - Following is an example: - - $ ECLIPSE_HOME=/home/scottrif/eclipse-yocto/scripts/eclipse ./build.sh -l neon/&DISTRO_NAME_NO_CAP; master yocto-&DISTRO; 2>&1 | tee build.log - - The previous example command adds the tag - you need for - neon/&DISTRO_NAME_NO_CAP; - to HEAD, then tells - the build script to use the local (-l) Git - checkout for the build. - After running the script, the file - org.yocto.sdk-release-date-archive.zip - is in the current directory. - - If necessary, start the Eclipse IDE - and be sure you are in the Workbench. - - Select "Install New Software" from - the "Help" pull-down menu. - - Click "Add". - - Provide anything you want in the - "Name" field. - - Click "Archive" and browse to the - ZIP file you built earlier. - This ZIP file should not be "unzipped", and must - be the *archive.zip file - created by running the - build.sh script. - - Click the "OK" button. - - Check the boxes that appear in - the installation window to install the - following: - - Yocto Project SDK Plug-in - Yocto Project Documentation plug-in - - - Finish the installation by clicking - through the appropriate buttons. - You can click "OK" when prompted about - installing software that contains unsigned - content. - - Restart the Eclipse IDE if - necessary. - - - - - - At this point you should be able to configure the - Eclipse Yocto Plug-in as described in the - "Configuring the Neon Eclipse Yocto Plug-in" - section. -
-
- -
- Configuring the Neon Eclipse Yocto Plug-In - - - Configuring the Neon Eclipse Yocto Plug-in involves setting the - Cross Compiler options and the Target options. - The configurations you choose become the default settings - for all projects. - You do have opportunities to change them later when - you configure the project (see the following section). - - - - To start, you need to do the following from within the - Eclipse IDE: - - - Choose "Preferences" from the - "Window" menu to display the Preferences Dialog. - - - Click "Yocto Project SDK" to display - the configuration screen. - - - The following sub-sections describe how to configure the - the plug-in. - - Throughout the descriptions, a start-to-finish example for - preparing a QEMU image for use with Eclipse is referenced - as the "wiki" and is linked to the example on the - Cookbook guide to Making an Eclipse Debug Capable Image - wiki page. - - - -
- Configuring the Cross-Compiler Options - - - Cross Compiler options enable Eclipse to use your specific - cross compiler toolchain. - To configure these options, you must select - the type of toolchain, point to the toolchain, specify - the sysroot location, and select the target - architecture. - - - Selecting the Toolchain Type: - Choose between "Standalone pre-built toolchain" - and - "Build system derived toolchain" for Cross Compiler - Options. - - - Standalone Pre-built Toolchain: - Select this type when you are using - a stand-alone cross-toolchain. - For example, suppose you are an - application developer and do not - need to build a target image. - Instead, you just want to use an - architecture-specific toolchain on - an existing kernel and target root - filesystem. - In other words, you have downloaded - and installed a pre-built toolchain - for an existing image. - - - Build System Derived Toolchain: - Select this type if you built the - toolchain as part of the - Build Directory. - When you select "Build system derived - toolchain", you are using the toolchain - built and bundled inside the Build - Directory. - For example, suppose you created a - suitable image using the steps in the - wiki. - In this situation, you would select - "Build system derived toolchain". - - - - - Specify the Toolchain Root Location: - If you are using a stand-alone pre-built - toolchain, you should be pointing to where it is - installed (e.g. - /opt/poky/&DISTRO;). - See the - "Installing the SDK" - section for information about how the SDK is - installed. - - If you are using a build system derived - toolchain, the path you provide for the - "Toolchain Root Location" field is the - Build Directory - from which you run the - bitbake command (e.g - /home/scottrif/poky/build). - For more information, see the - "Building an SDK Installer" - section. - - - Specify Sysroot Location: - This location is where the root filesystem for - the target hardware resides. - - - This location depends on where you - separately extracted and installed the - target filesystem when you either built - it or downloaded it. - - If you downloaded the root filesystem - for the target hardware rather than - built it, you must download the - sato-sdk image - in order to build any c/c++ projects. - - As an example, suppose you prepared an image - using the steps in the - wiki. - If so, the MY_QEMU_ROOTFS - directory is found in the - Build Directory - and you would browse to and select that directory - (e.g. /home/scottrif/build/MY_QEMU_ROOTFS). - - - For more information on how to install the - toolchain and on how to extract and install the - sysroot filesystem, see the - "Building an SDK Installer" - section. - - - Select the Target Architecture: - The target architecture is the type of hardware - you are going to use or emulate. - Use the pull-down "Target Architecture" menu - to make your selection. - The pull-down menu should have the supported - architectures. - If the architecture you need is not listed in - the menu, you will need to build the image. - See the - "Building a Simple Image" - section of the Yocto Project Development Tasks - Manual for more information. - You can also see the - wiki. - - - -
- -
- Configuring the Target Options - - - You can choose to emulate hardware using the QEMU - emulator, or you can choose to run your image on actual - hardware. - - - QEMU: - Select this option if you will be using the - QEMU emulator. - If you are using the emulator, you also need to - locate the kernel and specify any custom - options. - - If you selected the Build system derived - toolchain, the target kernel you built will be - located in the - Build Directory - in - tmp/deploy/images/machine - directory. - As an example, suppose you performed the steps in - the - wiki. - In this case, you specify your Build Directory path - followed by the image (e.g. - /home/scottrif/poky/build/tmp/deploy/images/qemux86/bzImage-qemux86.bin). - - - If you selected the standalone pre-built - toolchain, the pre-built image you downloaded is - located in the directory you specified when you - downloaded the image. - - Most custom options are for advanced QEMU - users to further customize their QEMU instance. - These options are specified between paired - angled brackets. - Some options must be specified outside the - brackets. - In particular, the options - serial, - nographic, and - kvm must all be outside the - brackets. - Use the man qemu command - to get help on all the options and their use. - The following is an example: - - serial ‘<-m 256 -full-screen>’ - - Regardless of the mode, Sysroot is already - defined as part of the Cross-Compiler Options - configuration in the "Sysroot Location:" field. - - - External HW: - Select this option if you will be using actual - hardware. - - - - - - Click the "Apply" and "OK" to save your plug-in - configurations. - -
-
-
- -
- Creating the Project - - - You can create two types of projects: Autotools-based, or - Makefile-based. - This section describes how to create Autotools-based projects - from within the Eclipse IDE. - For information on creating Makefile-based projects in a - terminal window, see the - "Makefile-Based Projects" - section. - - Do not use special characters in project names - (e.g. spaces, underscores, etc.). Doing so can - cause the configuration to fail. - - - - - To create a project based on a Yocto template and then display - the source code, follow these steps: - - - Select "C Project" from the "File -> New" menu. - - - Expand "Yocto Project SDK Autotools Project". - - - Select "Hello World ANSI C Autotools Projects". - This is an Autotools-based project based on a Yocto - template. - - - Put a name in the "Project name:" field. - Do not use hyphens as part of the name - (e.g. "hello"). - - - Click "Next". - - - Add appropriate information in the various fields. - - - Click "Finish". - - - If the "open perspective" prompt appears, - click "Yes" so that you are in the C/C++ perspective. - - - The left-hand navigation pane shows your project. - You can display your source by double clicking the - project's source file. - - - -
- -
- Configuring the Cross-Toolchains - - - The earlier section, - "Configuring the Neon Eclipse Yocto Plug-in", - sets up the default project configurations. - You can override these settings for a given project by following - these steps: - - - Select "Yocto Project Settings" from - the "Project -> Properties" menu. - This selection brings up the Yocto Project Settings - Dialog and allows you to make changes specific to an - individual project. - By default, the Cross Compiler Options and Target - Options for a project are inherited from settings you - provided using the Preferences Dialog as described - earlier in the - "Configuring the Neon Eclipse Yocto Plug-in" section. - The Yocto Project Settings Dialog allows you to override - those default settings for a given project. - - - Make or verify your configurations for the project and - click "OK". - - - Right-click in the navigation pane and select - "Reconfigure Project" from the pop-up menu. - This selection reconfigures the project by running - Autotools GNU utility programs - such as Autoconf, Automake, and so forth in the - workspace for your project. - Click on the "Console" tab beneath your source code - to see the results of reconfiguring your project. - - - -
- -
- Building the Project - - - To build the project select "Build All" from the - "Project" menu. - The console should update and you can note the cross-compiler - you are using. - - When building "Yocto Project SDK Autotools" projects, the - Eclipse IDE might display error messages for - Functions/Symbols/Types that cannot be "resolved", even when - the related include file is listed at the project navigator and - when the project is able to build. - For these cases only, it is recommended to add a new linked - folder to the appropriate sysroot. - Use these steps to add the linked folder: - - - Select the project. - - - Select "Folder" from the "File > New" menu. - - - In the "New Folder" Dialog, select "Link to alternate - location (linked folder)". - - - Click "Browse" to navigate to the include folder inside - the same sysroot location selected in the Yocto Project - configuration preferences. - - - Click "OK". - - - Click "Finish" to save the linked folder. - - - - -
- -
- Starting QEMU in User-Space NFS Mode - - - To start the QEMU emulator from within Eclipse, follow these - steps: - - See the - "Using the Quick EMUlator (QEMU)" - chapter in the Yocto Project Development Tasks Manual - for more information on using QEMU. - - - Expose and select "External Tools - Configurations ..." from the "Run -> External Tools" menu. - - - Locate and select your image in the navigation panel to - the left (e.g. qemu_i586-poky-linux). - - - Click "Run" to launch QEMU. - - The host on which you are running QEMU must have - the rpcbind utility running to be - able to make RPC calls on a server on that machine. - If QEMU does not invoke and you receive error messages - involving rpcbind, follow the - suggestions to get the service running. - As an example, on a new Ubuntu 16.04 LTS installation, - you must do the following in order to get QEMU to - launch: - - $ sudo apt-get install rpcbind - - After installing rpcbind, you - need to edit the - /etc/init.d/rpcbind file to - include the following line: - - OPTIONS="-i -w" - - After modifying the file, you need to start the - service: - - $ sudo service portmap restart - - - - If needed, enter your host root password in - the shell window at the prompt. - This sets up a Tap 0 connection - needed for running in user-space NFS mode. - - Wait for QEMU to launch. - - Once QEMU launches, you can begin operating - within that environment. - One useful task at this point would be to determine the - IP Address for the user-space NFS by using the - ifconfig command. - The IP address of the QEMU machine appears in the - xterm window. - You can use this address to help you see which particular - IP address the instance of QEMU is using. - - - -
- -
- Deploying and Debugging the Application - - - Once the QEMU emulator is running the image, you can deploy - your application using the Eclipse IDE and then use - the emulator to perform debugging. - Follow these steps to deploy the application. - - Currently, Eclipse does not support SSH port forwarding. - Consequently, if you need to run or debug a remote - application using the host display, you must create a - tunneling connection from outside Eclipse and keep - that connection alive during your work. - For example, in a new terminal, run the following: - - $ ssh -XY user_name@remote_host_ip - - Using the above form, here is an example: - - $ ssh -XY root@192.168.7.2 - - After running the command, add the command to be executed - in Eclipse's run configuration before the application - as follows: - - export DISPLAY=:10.0 - - Be sure to not destroy the connection during your QEMU - session (i.e. do not - exit out of or close that shell). - - - - Select "Debug Configurations..." from the - "Run" menu. - - In the left area, expand - "C/C++Remote Application". - - - Locate your project and select it to bring - up a new tabbed view in the Debug Configurations Dialog. - - - Click on the "Debugger" tab to see the - cross-tool debugger you are using. - Be sure to change to the debugger perspective in Eclipse. - - - Click on the "Main" tab. - - Create a new connection to the QEMU instance - by clicking on "new". - - Select "SSH", which means - Secure Socket Shell. - Optionally, you can select a TCF connection instead. - - - Click "Next". - - - Clear out the "Connection name" field and - enter any name you want for the connection. - - - Put the IP address for the connection in - the "Host" field. - For QEMU, the default is "192.168.7.2". - However, if a previous QEMU session did not exit - cleanly, the IP address increments (e.g. - "192.168.7.3"). - - You can find the IP address for the current QEMU - session by looking in the xterm that opens when - you launch QEMU. - - - - Enter "root", which - is the default for QEMU, for the "User" field. - Be sure to leave the password field empty. - - Click "Finish" to close the - New Connections Dialog. - - - If necessary, use the drop-down menu now in the - "Connection" field and pick the IP Address you entered. - - - Assuming you are connecting as the root user, - which is the default for QEMU x86-64 SDK images provided by - the Yocto Project, in the "Remote Absolute File Path for - C/C++ Application" field, browse to - /home/root/ProjectName - (e.g. /home/root/hello). - You could also browse to any other path you have write - access to on the target such as - /usr/bin. - This location is where your application will be located on - the QEMU system. - If you fail to browse to and specify an appropriate - location, QEMU will not understand what to remotely - launch. - Eclipse is helpful in that it auto fills your application - name for you assuming you browsed to a directory. - Tips - - - If you are prompted to provide a username - and to optionally set a password, be sure - you provide "root" as the username and you - leave the password field blank. - - - If browsing to a directory fails or times - out, but you can - ssh into your QEMU - or target from the command line and you - have proxies set up, it is likely that - Eclipse is sending the SSH traffic to a - proxy. - In this case, either use TCF , or click on - "Configure proxy settings" in the - connection dialog and add the target IP - address to the "bypass proxy" section. - You might also need to change - "Active Provider" from Native to Manual. - - - - - - Be sure you change to the "Debug" perspective in Eclipse. - - - Click "Debug" - - - Accept the debug perspective. - - - -
- -
- Using Linuxtools - - - As mentioned earlier in the manual, performance tools exist - (Linuxtools) that enhance your development experience. - These tools are aids in developing and debugging applications and - images. - You can run these tools from within the Eclipse IDE through the - "Linuxtools" menu. - - - - For information on how to configure and use these tools, see - http://www.eclipse.org/linuxtools/. - -

- Installing or Accessing the Oxygen Eclipse Yocto Plug-in - - - You can install the Eclipse Yocto Plug-in into the - Eclipse IDE one of two ways: use the Yocto Project's - Eclipse Update site to install the pre-built plug-in, - or build and install the plug-in from the latest - source code. - - -
- Installing the Pre-built Plug-in from the Yocto Project Eclipse Update Site - - - To install the Oxygen Eclipse Yocto Plug-in from the - update site, follow these steps: - - - Start up the Eclipse IDE. - - - In Eclipse, select "Install New - Software" from the "Help" menu. - - - Click "Add..." in the "Work with:" area. - - - Enter - &ECLIPSE_DL_PLUGIN_URL;/oxygen - in the URL field and provide a meaningful - name in the "Name" field. - - - Click "OK" to have the entry automatically - populate the "Work with:" field and to have - the items for installation appear in the window - below. - - - Check the boxes next to the following: - - Yocto Project SDK Plug-in - Yocto Project Documentation plug-in - - - - Complete the remaining software - installation steps and then restart the - Eclipse IDE to finish the installation of - the plug-in. - - You can click "OK" when prompted about - installing software that contains - unsigned content. - - - - -
- -
- Installing the Plug-in Using the Latest Source Code - - - To install the Oxygen Eclipse Yocto Plug-in from the - latest source code, follow these steps: - - - Be sure your build host has JDK version 1.8 - or greater. - On a Linux build host you can determine the - version using the following command: - - $ java -version - - - - Install X11-related packages: - - $ sudo apt-get install xauth - - - - In a new terminal shell, create a - Git repository with: - - $ cd ~ - $ git clone git://git.yoctoproject.org/eclipse-yocto - - - - Use Git to create the correct tag: - - $ cd ~/eclipse-yocto - $ git checkout -b oxygen/&DISTRO_NAME_NO_CAP; remotes/origin/oxygen/&DISTRO_NAME_NO_CAP; - - This creates a local tag named - oxygen/&DISTRO_NAME_NO_CAP; - based on the branch - origin/oxygen/&DISTRO_NAME_NO_CAP;. - You are put into a detached HEAD state, - which is fine since you are only going to - be building and not developing. - - - Change to the scripts - directory within the Git repository: - - $ cd scripts - - - - Set up the local build environment - by running the setup script: - - $ ./setup.sh - - When the script finishes execution, - it prompts you with instructions on how to - run the build.sh - script, which is also in the - scripts directory of - the Git repository created earlier. - - - Run the build.sh - script as directed. - Be sure to provide the tag name, - documentation branch, and a release name. - - - Following is an example: - - $ ECLIPSE_HOME=/home/scottrif/eclipse-yocto/scripts/eclipse ./build.sh -l oxygen/&DISTRO_NAME_NO_CAP; master yocto-&DISTRO; 2>&1 | tee build.log - - The previous example command adds the tag - you need for - oxygen/&DISTRO_NAME_NO_CAP; - to HEAD, then tells - the build script to use the local (-l) Git - checkout for the build. - After running the script, the file - org.yocto.sdk-release-date-archive.zip - is in the current directory. - - - If necessary, start the Eclipse IDE - and be sure you are in the Workbench. - - - Select "Install New Software" from - the "Help" pull-down menu. - - - Click "Add". - - - Provide anything you want in the - "Name" field. - - - Click "Archive" and browse to the - ZIP file you built earlier. - This ZIP file should not be "unzipped", and - must be the - *archive.zip file - created by running the - build.sh script. - - - Click the "OK" button. - - - Check the boxes that appear in - the installation window to install the - following: - - Yocto Project SDK Plug-in - Yocto Project Documentation plug-in - - - - Finish the installation by clicking - through the appropriate buttons. - You can click "OK" when prompted about - installing software that contains unsigned - content. - - - Restart the Eclipse IDE if necessary. - - - - - - At this point you should be able to configure the - Eclipse Yocto Plug-in as described in the - "Configuring the Oxygen Eclipse Yocto Plug-in" - section. - -
-
- -
- Configuring the Oxygen Eclipse Yocto Plug-In - - - Configuring the Oxygen Eclipse Yocto Plug-in involves - setting the Cross Compiler options and the Target - options. - The configurations you choose become the default - settings for all projects. - You do have opportunities to change them later when - you configure the project (see the following section). - - - - To start, you need to do the following from within the - Eclipse IDE: - - - Choose "Preferences" from the "Window" menu to - display the Preferences Dialog. - - - Click "Yocto Project SDK" to display - the configuration screen. - - - The following sub-sections describe how to configure - the plug-in. - - Throughout the descriptions, a start-to-finish - example for preparing a QEMU image for use with - Eclipse is referenced as the "wiki" and is linked - to the example on the - " Cookbook guide to Making an Eclipse Debug Capable Image" - wiki page. - - - -
- Configuring the Cross-Compiler Options - - - Cross Compiler options enable Eclipse to use your - specific cross compiler toolchain. - To configure these options, you must select - the type of toolchain, point to the toolchain, - specify the sysroot location, and select the target - architecture. - - - Selecting the Toolchain Type: - Choose between "Standalone pre-built toolchain" - and "Build system derived toolchain" for - Cross Compiler Options. - - - Standalone Pre-built Toolchain: - Select this type when you are using - a stand-alone cross-toolchain. - For example, suppose you are an - application developer and do not - need to build a target image. - Instead, you just want to use an - architecture-specific toolchain on - an existing kernel and target root - filesystem. - In other words, you have downloaded - and installed a pre-built toolchain - for an existing image. - - - Build System Derived Toolchain: - Select this type if you built the - toolchain as part of the - Build Directory. - When you select "Build system derived - toolchain", you are using the toolchain - built and bundled inside the Build - Directory. - For example, suppose you created a - suitable image using the steps in the - wiki. - In this situation, you would select - "Build system derived toolchain". - - - - - Specify the Toolchain Root Location: - If you are using a stand-alone pre-built - toolchain, you should be pointing to where - it is installed (e.g. - /opt/poky/&DISTRO;). - See the - "Installing the SDK" - section for information about how the SDK is - installed. - - If you are using a build system - derived toolchain, the path you provide for - the "Toolchain Root Location" field is the - Build Directory - from which you run the - bitbake command (e.g - /home/scottrif/poky/build). - - For more information, see the - "Building an SDK Installer" - section. - - - Specify Sysroot Location: - This location is where the root filesystem - for the target hardware resides. - - - This location depends on where you - separately extracted and installed the - target filesystem when you either built - it or downloaded it. - - If you downloaded the root filesystem - for the target hardware rather than - built it, you must download the - sato-sdk image - in order to build any c/c++ projects. - - As an example, suppose you prepared an - image using the steps in the - wiki. - If so, the - MY_QEMU_ROOTFS - directory is found in the Build Directory - and you would browse to and select that - directory (e.g. - /home/scottrif/poky/build/MY_QEMU_ROOTFS). - - - For more information on how to - install the toolchain and on how to extract - and install the sysroot filesystem, see the - "Building an SDK Installer" - section. - - - Select the Target Architecture: - The target architecture is the type of - hardware you are going to use or emulate. - Use the pull-down "Target Architecture" - menu to make your selection. - The pull-down menu should have the - supported architectures. - If the architecture you need is not listed - in the menu, you will need to build the - image. - See the - "Building a Simple Image" - section of the Yocto Project Development Tasks - Manual for more information. - You can also see the - wiki. - - - -
- -
- Configuring the Target Options - - - You can choose to emulate hardware using the QEMU - emulator, or you can choose to run your image on - actual hardware. - - - QEMU: - Select this option if you will be using the - QEMU emulator. - If you are using the emulator, you also - need to locate the kernel and specify any - custom options. - - If you selected the Build system derived - toolchain, the target kernel you built will be - located in the - Build Directory - in - tmp/deploy/images/machine - directory. - As an example, suppose you performed the - steps in the - wiki. - In this case, you specify your Build - Directory path followed by the image (e.g. - /home/scottrif/poky/build/tmp/deploy/images/qemux86/bzImage-qemux86.bin). - - - If you selected the standalone - pre-built toolchain, the pre-built image - you downloaded is located in the directory - you specified when you downloaded the - image. - - Most custom options are for advanced - QEMU users to further customize their QEMU - instance. - These options are specified between paired - angled brackets. - Some options must be specified outside the - brackets. - In particular, the options - serial, - nographic, and - kvm must all be - outside the brackets. - Use the man qemu - command to get help on all the options and - their use. - The following is an example: - - serial ‘<-m 256 -full-screen>’ - - Regardless of the mode, Sysroot is already - defined as part of the Cross-Compiler - Options configuration in the "Sysroot - Location:" field. - - - External HW: - Select this option if you will be using - actual hardware. - - - - - - Click "Apply and Close" to save your plug-in - configurations. - -
-
-
- -
- Creating the Project - - - You can create two types of projects: Autotools-based, or - Makefile-based. - This section describes how to create Autotools-based - projects from within the Eclipse IDE. - For information on creating Makefile-based projects in a - terminal window, see the - "Makefile-Based Projects" - section. - - Do not use special characters in project names - (e.g. spaces, underscores, etc.). Doing so can - cause configuration to fail. - - - - - To create a project based on a Yocto template and then - display the source code, follow these steps: - - - Select "C/C++ Project" from the "File -> New" menu. - - - Select "C Managed Build" from the available options and - click "Next". - - - Expand "Yocto Project SDK Autotools Project". - - - Select "Hello World ANSI C Autotools Projects". - This is an Autotools-based project based on a Yocto - template. - - - Put a name in the "Project name:" field. - Do not use hyphens as part of the name - (e.g. "hello"). - - - Click "Next". - - - Add appropriate information in the various fields. - - - Click "Finish". - - - If the "open perspective" prompt appears, - click "Yes" so that you in the C/C++ perspective. - - The left-hand navigation pane shows - your project. - You can display your source by double clicking the - project's source file. - - - -
- -
- Configuring the Cross-Toolchains - - - The earlier section, - "Configuring the Oxygen Eclipse Yocto Plug-in", - sets up the default project configurations. - You can override these settings for a given project by - following these steps: - - - Select "Yocto Project Settings" from - the "Project -> Properties" menu. - This selection brings up the Yocto Project Settings - Dialog and allows you to make changes specific to - an individual project. - By default, the Cross Compiler Options and - Target Options for a project are inherited from - settings you provided using the Preferences Dialog - as described earlier in the - "Configuring the Oxygen Eclipse Yocto Plug-in" - section. - The Yocto Project Settings Dialog allows you to - override those default settings for a given - project. - - - Make or verify your configurations for the - project and click "Apply and Close". - - - Right-click in the navigation pane and select - "Reconfigure Project" from the pop-up menu. - This selection reconfigures the project by running - Autotools GNU utility programs - such as Autoconf, Automake, and so forth in the - workspace for your project. - Click on the "Console" tab beneath your source code - to see the results of reconfiguring your project. - - - -
- -
- Building the Project - - To build the project select "Build All" from the - "Project" menu. - The console should update and you can note the - cross-compiler you are using (i.e. - i586-poky-linux-gcc in this example). - - When building "Yocto Project SDK Autotools" projects, - the Eclipse IDE might display error messages for - Functions/Symbols/Types that cannot be "resolved", - even when the related include file is listed at the - project navigator and when the project is able to - build. - For these cases only, it is recommended to add a new - linked folder to the appropriate sysroot. - Use these steps to add the linked folder: - - - Select the project. - - - Select "Folder" from the "File -> New" menu. - - - In the "New Folder" Dialog, click the "Advanced" - button and then activate "Link to - alternate location (linked folder)" button. - - - Click "Browse" to navigate to the include - folder inside the same sysroot location - selected in the Yocto Project - configuration preferences. - - - Click "Finish" to save the linked folder. - - - - -
- -
- Starting QEMU in User-Space NFS Mode - - - To start the QEMU emulator from within Eclipse, follow - these steps: - - See the - "Using the Quick EMUlator (QEMU)" - chapter in the Yocto Project Development Tasks Manual - for more information on using QEMU. - - - Expose and select "External Tools - Configurations ..." from the "Run -> External - Tools" menu. - - - Locate and select your image in the navigation - panel to the left - (e.g. qemu_i586-poky-linux). - - - Click "Run" to launch QEMU. - - The host on which you are running QEMU must - have the rpcbind utility - running to be able to make RPC calls on a - server on that machine. - If QEMU does not invoke and you receive error - messages involving - rpcbind, follow the - suggestions to get the service running. - As an example, on a new Ubuntu 16.04 LTS - installation, you must do the following in a new - shell in order to get QEMU to launch: - - $ sudo apt-get install rpcbind - - After installing rpcbind, - you need to edit the - /etc/init.d/rpcbind file - to include the following line: - - OPTIONS="-i -w" - - After modifying the file, you need to start the - service: - - $ sudo service portmap restart - - - - - If needed, enter your host root password in - the shell window at the prompt. - This sets up a Tap 0 - connection needed for running in user-space NFS - mode. - - - Wait for QEMU to launch. - - - Once QEMU launches, you can begin operating - within that environment. - One useful task at this point would be to determine - the IP Address for the user-space NFS by using the - ifconfig command. - The IP address of the QEMU machine appears in the - xterm window. - You can use this address to help you see which - particular - IP address the instance of QEMU is using. - - - -
- -
- Deploying and Debugging the Application - - - Once the QEMU emulator is running the image, you can deploy - your application using the Eclipse IDE and then use - the emulator to perform debugging. - Follow these steps to deploy the application. - - Currently, Eclipse does not support SSH port - forwarding. - Consequently, if you need to run or debug a remote - application using the host display, you must create a - tunneling connection from outside Eclipse and keep - that connection alive during your work. - For example, in a new terminal, run the following: - - $ ssh -XY user_name@remote_host_ip - - Using the above form, here is an example: - - $ ssh -XY root@192.168.7.2 - - After running the command, add the command to be - executed in Eclipse's run configuration before the - application as follows: - - export DISPLAY=:10.0 - - Be sure to not destroy the connection during your QEMU - session (i.e. do not - exit out of or close that shell). - - - - Select "Debug Configurations..." from the - "Run" menu. - - - In the left area, expand - "C/C++Remote Application". - - - Locate your project and select it to bring - up a new tabbed view in the Debug Configurations - Dialog. - - - Click on the "Debugger" tab to see the - cross-tool debugger you are using. - Be sure to change to the debugger perspective in - Eclipse. - - - Click on the "Main" tab. - - - Create a new connection to the QEMU instance - by clicking on "new". - Select "SSH", which - means Secure Socket Shell and then click "OK". - Optionally, you can select a TCF connection - instead. - - - Clear out the "Connection name" field and - enter any name you want for the connection. - - - Put the IP address for the connection in - the "Host" field. - For QEMU, the default is "192.168.7.2". - However, if a previous QEMU session did not exit - cleanly, the IP address increments (e.g. - "192.168.7.3"). - - You can find the IP address for the current - QEMU session by looking in the xterm that - opens when you launch QEMU. - - - - Enter "root", which - is the default for QEMU, for the "User" field. - Be sure to leave the password field empty. - - - Click "Finish" to close the New Connections Dialog. - - - If necessary, use the drop-down menu now in the - "Connection" field and pick the IP Address you - entered. - - - Assuming you are connecting as the root - user, which is the default for QEMU x86-64 SDK - images provided by the Yocto Project, in the - "Remote Absolute File Path for C/C++ Application" - field, browse to - /home/root/ProjectName - (e.g. /home/root/hello). - You could also browse to any other path you have - write access to on the target such as - /usr/bin. - This location is where your application will be - located on the QEMU system. - If you fail to browse to and specify an appropriate - location, QEMU will not understand what to remotely - launch. - Eclipse is helpful in that it auto fills your - application name for you assuming you browsed to a - directory. - Tips - - - If you are prompted to provide a username - and to optionally set a password, be sure - you provide "root" as the username and you - leave the password field blank. - - - If browsing to a directory fails or times - out, but you can - ssh into your QEMU - or target from the command line and you - have proxies set up, it is likely that - Eclipse is sending the SSH traffic to a - proxy. - In this case, either use TCF , or click on - "Configure proxy settings" in the - connection dialog and add the target IP - address to the "bypass proxy" section. - You might also need to change - "Active Provider" from Native to Manual. - - - - - - Be sure you change to the "Debug" perspective in - Eclipse. - - - Click "Debug" - - - Accept the debug perspective. - - - -
- -
- Using Linuxtools - - - As mentioned earlier in the manual, performance tools exist - (Linuxtools) that enhance your development experience. - These tools are aids in developing and debugging - applications and images. - You can run these tools from within the Eclipse IDE through - the "Linuxtools" menu. - - - - For information on how to configure and use these tools, - see - http://www.eclipse.org/linuxtools/. - -
