Hello, I am trying to compile a simple hello world application using gcc 3.2 on 11.00. I get the following error when I run the application: /usr/lib/dld.sl: Unresolved symbol: pthread_once (code) from /usr/local/lib/gcc -lib/hppa2.0n-hp-hpux11.00/3.2/../../../libgcc_s.sl However if I link with pthread then I do not get this crash. Why do I need to link with pthread ? Is there some patch that I need to install ? Thanks and regards Sonison James
