GCC cross compiler builds

techguyz

Hi Experts,

During the compilation of Linux kernel is the GCC toolchain is differently build for user space code, glibc code and Kernel space code ?

If yes why it is build so ?

Regards,

    I'm not sure about your talking ?

    Are you talking about the .so file ?

    In this case the .SO is only a source of object

    specificaly code in assembler, for the drivers for exemple.

    But not limited exclusivly to a non-user space code. (in ARM FIQ)

    Regard's

    If you want to cross compile Linux apps you need to use a variant of GCC using libraries targeted at the Linux ABI

    i.e. from this page: Linaro Releases you would be using something like arm-linux-gnueabihf  rather than the bare-metal targeted arm-none-eabi

    You can actually build the kernel with either GCC variant, because it's self contained and doesn't reply on any GCC libs.
