[LTP] [PATCH] Fix build with libnuma-dev on some distributions

[Petr Vorel <pvorel@suse.cz>]

Hi,

> ----- Original Message -----
> > On some distributions when libnuma-dev is installed the tst_numa.o,
> > which was added to libltp.a pulls in symbols from numa library to random
> > unrealted tests which breaks the build.

> > This commit hence moves the tst_numa to a separate libltpnuma.a library
> > that is used for linking only for tests that actually use it and link
> > with -lnuma.

The problem persists [1] [2]:
/usr/src/ltp/testcases/kernel/syscalls/set_mempolicy/set_mempolicy04.c:105: undefined reference to `numa_allocate_nodemask'
/usr/src/ltp/testcases/kernel/syscalls/set_mempolicy/set_mempolicy04.c:110: undefined reference to `numa_bitmask_setbit'
/usr/src/ltp/testcases/kernel/syscalls/set_mempolicy/set_mempolicy04.c:112: undefined reference to `set_mempolicy'

Agree.

+ other LTP libraries are hidden in some subdirectories (which might be
confusing), but I like there is not lib/ and lib<foo>/ in root directory.

Kind regards,
