libnuma: Problem with static library

libnuma: Problem with static library

[Almaz Mirgasimov]

Hi all,

I have some problem when running my program statically linked with libnuma.
When I try to run it I get following error message

 request to allocate mask for invalid number; abort

I think the reason for such behavior is not initialized 'cpumask_sz',
because 'numa_init' was not called automatically.

To solve this problem I slightly patched numactl sources and called
'numa_init' in my program manually.
But is there any better way?

To link statically I passed '-Wl,-Bstatic -lnuma' to 'ld' linker.
My numactl version is 2.0.7

Best regards

That's a long standing regression from the 2.x changes.

Should be fixed with
