Problems with GDB 5.1 and Pthreads

[Marcos Pindado Sebastián <mpindado at signalia dot es>]

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.
