Dear linux-il colleagues,
GCC 4.6 introduced many new warnings that cause -Werror to stop the
compilation for some platforms, such as powerpc, in various files.
Oh, I didn't even know they finally introduced -Werror... Good.
If it is in the way maybe KCFLAGS=-Wno-error or similar may serve as a workaround? Or
KBUILD_ENABLE_EXTRA_GCC_CHECKS="" ?
Cf. Documentation/kbuild/kbuild.txt
You didn't say what kernel version - I just went to LXR for the latest.
My question is in general, is there somewhere where the relationship
between kernel version and gcc version (or other compiler version) is made
explicit?
Not that I know of. The minimal versions of everything needed are in
Documentation/Changes. I guess you are not interested in "minimal".
I would be very much surprised if the kernel could not be built with gcc-4.6 -
this is stock on Fedora, so lots of people must be using it. Maybe not on
PowerPC,
though
