<title>Optionally Using an External Toolchain</title>
<para>
You might want to use an external toolchain as part of your
development.
If this is the case, the fundamental steps you need to accomplish
are as follows:
<itemizedlist>
<listitem><para>
Understand where the installed toolchain resides.
For cases where you need to build the external toolchain,
you would need to take separate steps to build and install
the toolchain.
</para></listitem>
<listitem><para>
Make sure you add the layer that contains the toolchain to
your <filename>bblayers.conf</filename> file through the
<ulink url='&YOCTO_DOCS_REF_URL;#var-BBLAYERS'><filename>BBLAYERS</filename></ulink>
variable.
</para></listitem>
<listitem><para>
Set the
<ulink url='&YOCTO_DOCS_REF_URL;#var-EXTERNAL_TOOLCHAIN'><filename>EXTERNAL_TOOLCHAIN</filename></ulink>
variable in your <filename>local.conf</filename> file
to the location in which you installed the toolchain.
</para></listitem>
</itemizedlist>
A good example of an external toolchain used with the Yocto Project
is <trademark class='registered'>Mentor Graphics</trademark>
Sourcery G++ Toolchain.
You can see information on how to use that particular layer in the
<filename>README</filename> file at
<ulink url='http://github.com/MentorEmbedded/meta-sourcery/'></ulink>.
You can find further information by reading about the
<ulink url='&YOCTO_DOCS_REF_URL;#var-TCMODE'><filename>TCMODE</filename></ulink>
variable in the Yocto Project Reference Manual's variable glossary.
