Subject: [PATCH 3/3] Kbuild: use -std=gnu11 for KBUILD_USERCFLAGS
|
|
|
|
As we change the C language standard for the kernel from gnu89 to
|
|
gnu11, it makes sense to also update the version for user space
|
|
compilation.
|
|
|
|
Some users have older native compilers than what they use for
|
|
kernel builds, so I considered using gnu99 as the default version
|
|
for wider compatibility with gcc-4.6 and earlier.
|
|
|
|
However, testing with older compilers showed that we already require
|
|
HOSTCC version 5.1 as well because a lot of host tools include
|
|
linux/compiler.h that uses __has_attribute():
|
|
|
|
CC tools/objtool/exec-cmd.o
|
|
In file included from tools/include/linux/compiler_types.h:36:0,
|
|
from tools/include/linux/compiler.h:5,
|
|
from exec-cmd.c:2:
|
|
tools/include/linux/compiler-gcc.h:19:5: error: "__has_attribute" is not defined [-Werror=undef]
