+make a small test program, that uses pthread_cancel and try to compile and 
+link it.

+or you could find out with strings if that function is in there.
+
+lastly, i see you're building the .a file. don't do it and make it dynamic, 
+that could also have been an issue. if not at least it'll make the problem 
+alot more visible
