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:
