import_array causing install errors

[dc1340]

Trying to install on a brand new Mac (10.12.6):

python --version

Commenting out the import_array() calls in Frame.cpp leads to the following error:

sudo python setup.py install

Should also state that I modified SmartPtr.hpp to deal with a previous error where pthread_spin_init, pthread_spin_destroy, etc, were apparently not portable on Mac OS. Following the thread here, I added the following lines to SmartPtr.hpp:

#include <libkern/OSAtomic.h>

\\...
\\...
\\...

typedef int pthread_spinlock_t;

int pthread_spin_init(pthread_spinlock_t *lock, int pshared) {
    __asm__ __volatile__ ("" ::: "memory");
    *lock = 0;
    return 0;
}

int pthread_spin_destroy(pthread_spinlock_t *lock) {
    return 0;
}

int pthread_spin_lock(pthread_spinlock_t *lock) {
    while (1) {
        int i;
        for (i=0; i < 10000; i++) {
            if (__sync_bool_compare_and_swap(lock, 0, 1)) {
                return 0;
            }
        }
        sched_yield();
    }
}

int pthread_spin_trylock(pthread_spinlock_t *lock) {
    if (__sync_bool_compare_and_swap(lock, 0, 1)) {
        return 0;
    }
    return EBUSY;
}

int pthread_spin_unlock(pthread_spinlock_t *lock) {
    __asm__ __volatile__ ("" ::: "memory");
    *lock = 0;
    return 0;
}
