在Yocto树中使用预构建的工具链

Question

Is there a way to configure Yocto to use Pre Built toolchain (like downloaded from CodeSourcery, etc.). I want to avoid building toolchain because it takes too much time and using new toolchain is not of my concern.

I was using this feature in buildroot.

Thanks in Advance!!!

Sure, though I'm not using it that often.

For the CodeSourcery-toolchains, have a look at meta-sourcery , which is a layer adding support for the CodeSourcery toolchain.

Basically, you just need to add this layer to BBLAYERS in your conf/bblayers.conf . Though, make sure that you add it before the meta layer.

Then you should just need to add s listed before the meta layer, as this ensures meta-sourcery gets priority over meta. Set EXTERNAL_TOOLCHAIN = "/path/to/your/sourcery-g++-install" s listed before the meta layer, as this ensures meta-sourcery gets priority over meta. Set EXTERNAL_TOOLCHAIN = "/path/to/your/sourcery-g++-install" to your conf/local.conf .

Be sure to checkout the README.md in meta-sourcery, as there are some extra stuff you might need to be aware of. (Depending on your build machine configuration etc).
