The removed # version check just so happened to prevent __compiletime_error() from # being defined with clang because it pretends to be GCC 4.2.1 for # compatibility but the error attribute was not added to clang until # 14.0.0. # # Commit 815f0ddb346c ("include/linux/compiler.h: make compiler-.h # mutually exclusive") and commit a3f8a30f3f00 ("Compiler Attributes: use # feature checks instead of version checks") refactored the handling of # attributes in the main kernel to avoid situations like this but that # refactoring has never been done for the tools directory. # # Refactoring is a rather large undertaking and this has never been an # issue before so instead, just guard the definition of # __compiletime_error() with __has_attribute() so that there are no more # errors. # # Fixes: 4e59869aa655 ("compiler-gcc.h: drop checks for older GCC versions") # Signed-off-by: Nathan Chancellor <nathan@kernel.org> # Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> # < /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/arm-linux-gnueabi/bin/arm-linux-gnueabi-gcc --version # < /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/arm-linux-gnueabi/bin/arm-linux-gnueabi-ld --version # < git log --format=%s --max-count=1 d0ee23f9d78be5531c4b055ea424ed0b489dfe9b # < make -s -j 8 ARCH=arm O=/kisskb/build/linus_mv78xx0_defconfig_arm-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/arm-linux-gnueabi/bin/arm-linux-gnueabi- mv78xx0_defconfig * * Compiler is too old. * Your GCC version: 4.9.4 * Minimum GCC version: 5.1.0 * scripts/Kconfig.include:44: Sorry, this compiler is not supported. make[2]: * [/kisskb/src/scripts/kconfig/Makefile:94: mv78xx0_defconfig] Error 1 make[1]: * [/kisskb/src/Makefile:616: mv78xx0_defconfig] Error 2 make: * [Makefile:219: __sub-make] Error 2 Command 'make -s -j 8 ARCH=arm O=/kisskb/build/linus_mv78xx0_defconfig_arm-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/arm-linux-gnueabi/bin/arm-linux-gnueabi- mv78xx0_defconfig' returned non-zero exit status 2 # rm -rf /kisskb/build/linus_mv78xx0_defconfig_arm-gcc4.9 # Build took: 0:00:01.067560
