OpenEmbedded/Yocto layer for the Sourcery G++ toolchain
|
|
|
=======================================================
|
|
|
|
|
|
+Usage & Instructions
|
|
|
+--------------------
|
|
|
+
|
|
|
+- Ensure that you have the Sourcery G++ toolchain installed.
|
|
|
+- If it's an ia32 toolchain, make sure you did *not* let it modify your PATH,
|
|
|
+ and if you did, remove it.
|
|
|
+
|
|
|
+ This is necessary because the ia32 Sourcery G++ toolchain
|
|
|
+ shipped non-prefixed binaries (e.g. `gcc` rather than `i586-none-linux-gcc`), which
|
|
|
+ means bitbake would be unable to run the host's gcc directly anymore.
|
|
|
+- Add the meta-sourcery layer to your `BBLAYERS` in `conf/bblayers.conf`. Please make
|
|
|
+ certain that it is listed before the `meta` layer, as this ensures meta-sourcery gets
|
|
|
+ priority over meta.
|
|
|
+- Set `EXTERNAL_TOOLCHAIN = "/path/to/your/sourcery-g++-install"` in `conf/local.conf`.
