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 -- Oleg Goldshmidt | [email protected]
