If so, someone familiar with Darwin needs to provide (a tested) darwin specific
proc.c implementation which can be added to libgomp/config/darwin/proc.c
to replace the libgomp/config/posix/proc.c version.
Here is code that does so:
#include <sys/types.h>
#include <sys/sysctl.h>
int main()
{
int mib[2] = { CTL_HW, HW_AVAILCPU };
int result, len;
len = sizeof (result);
sysctl (mib, 2, &result, &len, NULL, 0);
printf ("%d\n", result);
}
If you need to retrieve the number of processors in the system (i.e. the
upper bound to HW_AVAILCPU, because the latter may change if a different
power management modes is activated), you should use HW_NCPU instead.
