<cheatsheet title="Creating a Hello World ANSI C or C++ Autotools Project">
<intro>
<description>
This cheat sheet will guide you through the process of creating and
building a "Hello World ANSI C Autotools Project" or
a "Hello World C++ Autotools Project"
application that uses a Yocto Project template.

<item title="Open the C/C++ Perspective" dialog="false" skip="true">
<description>
Select <b>Window</b> > <b>Open Perspective</b> >
<b>Other...</b> from the menu bar.<br/>
Choose <b>C/C++</b> from the <b>Open Perspective</b> dialog.
Click <b>OK</b>.

<description>
You need to specify a toolchain and sysroot location before
building any project in the workspace.
</description>
<subitem>
<description>
The global settings can be modified in the <b>Yocto Project ADT</b>
section of the eclipse preferences. Select <b>Window</b> >
<b>Preferences</b> from the menu bar and then select the section
<b>Yocto Project ADT</b>. These settings are the default ones for
every project you create in the workspace.

<description>
Provide a <b>Toolchain Root Location</b> (e.g.
/opt/poky/1.3 or some other location on the filesystem).
</description>
</subitem>
<subitem>
<description>
Provide a <b>Sysroot Location</b>. This is the filesystem
containing libraries, headers etc. used while cross-building
binaries for the target.
</description>
</subitem>
<subitem>
<description>
If more than one toolchain is found in the <b>Toolchain
Root Location</b>, use the drop-down box to select the <b>Target
Architecture</b>. Make sure that the selected sysroot matches
the toolchain.
</description>
</subitem>
<subitem>
<description>
Choose in the <b>Target Options</b> whether the target is a QEMU
emulation (kernel location required) or an external hardware.
The target is used for running or remote debugging the binaries
created for it.
</description>
</subitem>

<description>
Save the settings with <b>Apply</b> and <b>OK</b>. You can later
change these settings for any project from the menu
<b>Project</b> > <b>Change Yocto Project Settings</b>.

<description>
If needed make some Advanced settings. Confirm them with

<description>
Click <b>Finish</b> to create the project in your workspace. You
will find the created project in the <b>Project Explorer</b> view.

</subitem>
</item>
<item title="Build the project" dialog="true">
<description>
Create the project's binary using a specified toolchain and
sysroot.
</description>
<subitem>
<description>
Make sure that the project is on focus in the
<b>Project Explorer</b> view.
</description>
</subitem>
<subitem>
<description>
If you want to change the default settings for toolchain and
sysroot location go to <b>Project</b> >
<b>Change Yocto Project Settings</b> in the menu bar. Finish the
editing by pressing <b>OK</b>.
</description>
</subitem>
<subitem>
<description>
If you have changed the settings in the previous step, call
<b>Project</b> > <b>Reconfigure Project</b> to reconfigure the
project with these new settings (e.g. create the correct Makefiles
that make use of the selected toolchain and sysroot).
</description>
</subitem>
<subitem>
<description>
Build the project with a click on the hammer symbol in the
Toolbar. Alternatively, go to <b>Project</b> >
<b>Build Project</b>. If you didn't change the default
toolchain and sysroot, now the configuring step will be executed
at first, followed by the build step itself.
</description>

<subitem>
<description>
Observe the output in the different consoles (e.g.
<b>Configure [HelloWorld]</b> and
<b>CDT Build Console [HelloWorld]</b>) to check if everything
was successful.

<onCompletion>
Congratulations, you have completed this cheat sheet! You may
continue with editing, rebuilding or debugging the
Hello World Autotools Project.
