Simple Link problem
 

I link my program with this
g++ -0 unittest unittest.cpp baseobject.cpp thread.cpp libthread.a

which results in Segmentation Fault when being run
on
pthread_create (&tid, NULL, &my_func, NULL);

Why there is seg fault when the linker did not complain?
I ran it thru the debugger, i found my_func to be not NULL and tid is 0, what is the problem? is it some dynamic library or static library link problems?
Thanks
Jack

tid needs to be set up to point to a valid memory address. pthread_create returns the tread id into this memory address.
