I have cvsupped twice or thrice (about 6 hours in between) in between builds to
make sure I didn't miss a commit...
looking at the file uthread_mutex.c reveals two include files which might
contain the PTHREAD declarations: pthread.h and pthread_private.h
pthread.h contains the declarations after examination. Curious thing is that
the datestamp is from November the 29th, just a day or two before the problems
started...
snip of pthread.h
enum pthread_mutextype {
PTHREAD_MUTEX_DEFAULT = 1,
PTHREAD_MUTEX_RECURSIVE = 2,
PTHREAD_MUTEX_NORMAL = 3,
PTHREAD_MUTEX_ERRORCHECK = 4,
MUTEX_TYPE_MAX
};
This enumeration looks good to me...
Now to look at uthread_mutex.c:
#ifdef _THREAD_SAFE
#include <pthread.h>
#include "pthread_private.h"
Most logical conclusion I can make is that _THREAD_SAFE isn't defined
somewhere... Else we would have the declarations of pthread.h at our disposal.
Someone care to enlighten me some more on the matter? Because I have no clue
where to look for the #define of _THREAD_SAFE.
Also some more info upon what it's trying to do here might help my
understanding somewhat better... It's trying to build up some sort of thread
routines, I read through pthread(3) but cannot see what uthread is for then...
