Crafty 23.5 NUMA compile issue

[jdart]

On Ubuntu 12.10 x64 (a fairly recent version), after installing libnuma-dev, I am getting this error building Crafty 23.5 using the linux-amd64 target:

main.c:4027:5: error: too many arguments to function ‘numa_node_to_cpus’

The man page for numa_node_to_cpus says it is declared like this:

int numa_node_to_cpus(int node, struct bitmask *mask);

but this does not match the signature in the code.

There are different NUMA API versions around. Crafty supports v1 while recent installations implement v2. I don't know whether it is possible to determine the correct API version at runtime, maybe with dlopen()/dlsym()? For v2, in order to determine the number of CPUs of a node you need to allocate a bitmask structure first, then call the function above, then query the CPU count from the bitmask struct, and finally free the structure if it was allocated on the heap.

I'll take a look. I've not compiled and run on a NUMA box recently, it is possible/likely that the library has changed a bit...
