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
Almaz Mirgasimov

That's a long standing regression from the 2.x changes.
Should be fixed with
