- The Yocto Project presents the kernel as a fully patched, history-clean git
- repository.
- The git tree represents the selected features, board support,
- and configurations extensively tested by Yocto Project.
- The Yocto Project kernel allows the end user to leverage community
- best practices to seamlessly manage the development, build and debug cycles.
+ Recall that earlier we talked about how to use an existing toolchain
+ tarball that had been installed into <filename>/opt/poky</filename>,
+ which is outside of the Poky build environment
+ (see <xref linkend='using-an-existing-toolchain-tarball'>
+ “Using an Existing Toolchain Tarball”)</xref>.
+ And, that sourcing your architecture-specific environment setup script
+ initializes a suitable development environment.
+ This setup occurs by adding the compiler, QEMU scripts, QEMU binary,
+ a special version of <filename>pkgconfig</filename> and other useful
+ utilities to the <filename>PATH</filename> variable.
+ Variables to assist pkgconfig and autotools are also defined so that,
+ for example, <filename>configure.sh</filename> can find pre-generated
+ test results for tests that need target hardware on which to run.
+ These conditions allow you to easily use the toolchain outside of the
+ Poky build environment on both autotools-based projects and
+ makefile-based projects.

<para>
- This manual describes the Yocto Project kernel by providing information
- on its history, organization, benefits, and use.
- The manual consists of two sections:
- <itemizedlist>
- <listitem><para>Concepts - Describes concepts behind the kernel.
- You will understand how the kernel is organized and why it is organized in
- the way it is. You will understand the benefits of the kernel's organization
- and the mechanisms used to work with the kernel and how to apply it in your
- design process.</para></listitem>
- <listitem><para>Using the Kernel - Describes best practices and "how-to" information
- that lets you put the kernel to practical use. Some examples are "How to Build a
- Project Specific Tree", "How to Examine Changes in a Branch", and "Saving Kernel
- Modifications."</para></listitem>
- </itemizedlist>
+ For an autotools-based project you can use the cross-toolchain by just
+ passing the appropriate host option to <filename>configure.sh</filename>.
+ The host option you use is derived from the name of the environment setup
+ script in <filename>/opt/poky</filename> resulting from unpacking the
+ cross-toolchain tarball.
+ For example, the host option for an ARM-based target that uses the GNU EABI
+ is <filename>armv5te-poky-linux-gnueabi</filename>.
+ Note that the name of the script is
+ <filename>environment-setup-armv5te-poky-linux-gnueabi</filename>.
+ Thus, the following command works:
+ <literallayout class='monospaced'>
+ $ configure &dash;&dash;host-armv5te-poky-linux-gnueabi &dash;&dash;with-libtool-sysroot=&lt;sysroot-dir&gt;
+ </literallayout>

+ <para>
+ For a makefile-based project you use the cross-toolchain by making sure
+ the tools are used.
+ You can do this as follows:
+ <literallayout class='monospaced'>
+ CC=arm-poky-linux-gnueabi-gcc
+ LD=arm-poky-linux-gnueabi-ld
+ CFLAGS=”${CFLAGS} &dash;&dash;sysroot=&lt;sysroot-dir&gt;”
+ CXXFLAGS=”${CXXFLAGS} &dash;&dash;sysroot=&lt;sysroot-dir&gt;”
