I'm trying to compile some code which uses openal, but, I get this error :

root@iridium:~/frog# gcc frog.cc -o frog -lGL -lGLU -lSDL -lpthread -lopenal
/usr/local/lib/libopenal.so: undefined reference to `pthread_atfork'
collect2: ld returned 1 exit status

hmm this is my ld.so.conf :

/usr/local/lib
/usr/X11R6/lib
/usr/i486-slackware-linux/lib
/opt/kde/lib
/usr/lib/qt/lib
/usr/lib
ld.so.conf lines 1-6/6 (END)

my gcc info :

root@iridium:/etc# gcc -v
Reading specs from /usr/lib/gcc-lib/i486-slackware-linux/3.2.3/specs

here are my pthread libs ...

root@iridium:/lib# ls -l libpthread*
-rwxr-xr-x 1 root root 94112 May 19 2003 libpthread-0.10.so*
lrwxrwxrwx 1 root root 18 Dec 2 12:30 libpthread.so.0 -> libpthread-0.10.so*

root@iridium:/usr/lib# ls -l libpthread*
-rw-r--r-- 1 root root 129728 May 19 2003 libpthread.a
lrwxrwxrwx 1 root root 25 Dec 2 12:30 libpthread.so -> ../../lib/libpthread.so.0*

and in my /usr/include/pthread.h, just to kick me in the face, is the function prototype :

extern int pthread_atfork (void (*__prepare) (void),
void (*__parent) (void),
void (*__child) (void)) __THROW;

This is on a slack 9.1, recompiled 2.4.22 kernel.

Anyone got any light to shed ?

I just had a look into my libpthread.a and behold it does not have a pthread_atfork function. It includes this however : old_pthread_atfork.o

root@iridium:/usr/lib# find / -name old_pthread_atfork.o -print
root@iridium:/usr/lib#

It's not there.
