Subject: [PATCH] link with -latomic if needed (again ...)
|
|
|
|
numactl unconditionally uses __atomic_fetch_and but some architectures
|
|
(e.g. sparc) needs to link with -latomic to be able to use it. So check
|
|
if -latomic is needed and update numa.pc accordingly.
|
|
|
|
This linking was made by e0de0d9e981ddb53bdeb4a4b9dc43046c9ff4ff9 but
|
|
wrongly reverted by 10c277c20768be9a563f75265bcd7e73954763ad resulting
|
|
in the following build failure on sparc or microblaze:
|
|
|
|
/nvmedata/autobuild/instance-7/output-1/per-package/numactl/host/bin/../lib/gcc/sparc-buildroot-linux-uclibc/10.4.0/../../../../sparc-buildroot-linux-uclibc/bin/ld: ./.libs/libnuma.a(libnuma.o): in function `numa_police_memory':
|
|
libnuma.c:(.text+0xe28): undefined reference to `__atomic_fetch_and_1'
|
|
|
|
Fixes:
