Hi. I am developing under linux SlackWare 7.0 and have several problems with gdb and multithreaded programs. Gdb is 5.1 configured on P3 PC. - Every call to a pthread function results in the reception of a SIG32. I have tried to resolve this by ignoring that signal, but... - It does not appear any message indicating a new thread is created. - I don't see any thread when writing : info threads. - The command " thread x" does not work, it says it has no id thread. - When I set a breakpoint in the code that a thread other than main thread the program does not stop in it, but recives a SIGTRAP when that thread exists. It seems there is no thread over there although simple multithread programs work fine (when not debugging) so I am assuming Slackware does well with threads. Is there any configuration option I have miss? Is there any patch to resolve this? Thank you very much.
