168How do I use an external toolchain? 168How do I use an external toolchain?

171The toolchain configuration is very flexible and customizable. It 171See the ":ref:`dev-manual/external-toolchain:optionally using an external toolchain`"
172is primarily controlled with the :term:`TCMODE` variable. This variable 172section in the Development Task manual.
173controls which ``tcmode-*.inc`` file to include from the
174``meta/conf/distro/include`` directory within the :term:`Source Directory`.
175
176The default value of :term:`TCMODE` is "default", which tells the
177OpenEmbedded build system to use its internally built toolchain (i.e.
178``tcmode-default.inc``). However, other patterns are accepted. In
179particular, "external-\*" refers to external toolchains. One example is
180the Sourcery G++ Toolchain. The support for this toolchain resides in
181the separate ``meta-sourcery`` layer at
182https://github.com/MentorEmbedded/meta-sourcery/.
183
184In addition to the toolchain configuration, you also need a
185corresponding toolchain recipe file. This recipe file needs to package
186up any pre-built objects in the toolchain such as ``libgcc``,
187``libstdcc++``, any locales, and ``libc``.
