I am currently working on a custom project using the meta-meson layer for the
scarthgap platform. The project requires building a custom Linux kernel that
explicitly depends on GCC 12.x. However, the meta-meson layer (and the
associated Yocto environment) defaults to GCC 13.x for both the toolchain and
the kernel build.
I would like to configure the build system to use GCC 12.x exclusively for
building the kernel, while keeping GCC 13.x for all other components in the
environment. Is there any way to do this?
The quick answer is no.
I'm curious to know what specifically requires gcc 12.x, and not any
other version?
I assume an outdated vendor kernel.
Just backport patches from upstream that fixed build issues with GCC 13,
it'll probably be much easier (and maybe consider upgrading to a newer
kernel (or at least newer stable kernel)) than trying to figure out how
to build the kernel with one GCC and the rest of the system with another
one.
Cheers,
Quentin
