How do I specify which compiler toolchain Yocto uses to build images?

For example, how could I get my image to be compiled using:

gcc-linaro-arm-linux-gnueabihf-4.7-2013.03-20130313_linux?

What does core-image-sato has to do with the toolchains (they supply with Yocto)? I don't understand...

Solution

  • In your local.conf file, specify the path of your toolchain in your system.

    EXTERNAL_TOOLCHAIN = "/home/manjunath/linaro/gcc-linaro-arm-linux-gnueabihf-4.7-2014.11-20121123_linux"

    In your original toolchain distro add toolchain-external-linaro.inc

    More specifically

    you get a directory named meta-linaro-toolchain. You may copy complete or

    Add .inc to your distribution (sources/poky/meta-yocto/conf/distro/ in my case).
