Building Enea Linux or compiling applications requires that your git environment be setup properly and for certain packages to be installed on your Linux development host. The following chapter details the configurations needed on the build environment in order to properly use Enea Linux.

If you intend to get Enea Linux sources and build Enea Linux yourself, you will need Git installed in your build environemtn. Please refer to Getting Started - First-Time Git Setup, for more details on how to set up your git environment correctly, including how to set your identity using the following commands: $ git config --global user.name "John Doe" $ git config --global user.email johndoe@example.com

In order to work with Enea Linux, you need a set of tools installed on the build machine, depending on the scenario you use. The following chapters will describe what tools to install on the build machine.

Using the pre-built binaries, you can get up and running more quickly. Since building is not required, there are not a lot of packaes and tools that need to be installed but a few are still required: wget - for downloading the Enea Linux binaries tar - for decompressing the Enea Linux release tftpboot server - for deploying Enea Linux on target NFS server - in case you want to mount the root file system over NFS

Building Enea Linux requires a set of packages to be installed on your Linux development host. The list of required packages is described in the Yocto Project reference manual.

Before installing Enea Linux, make sure that bash is the default shell. To verify the default system shell If your system runs Ubuntu, use list to verify if /usr/bin is a symbolic link to bash: # ls -l /bin/sh lrwxrwxrwx 1 root root 4 2012-03-02 11:53 /bin/sh -> bash Optionally, in case the link points to dash, change it through the following steps: # ls -l /bin/sh lrwxrwxrwx 1 root root 4 2012-03-02 11:53 /bin/sh -> dash # sudo dpkg-reconfigure dash Use dash as the default system shell (/bin/sh)?
