libpthread-dev and the binary package libpthread20 seem to have gone in gutsy; but you might still have them if you upgraded from feisty.
I fell over this problem building rhythmbox and the error I got was: GThread-ERROR **: file /build/buildd/glib2.0-2.14.1/gthread/gthread-posix.c: line 140 (): error 'Function not implemented' during 'pthread_getschedparam (pthread_self(), &policy, &sched)' aborting... Aborted (core dumped) and an easily missed warning: /usr/bin/ld: warning: libpthread.so.0, needed by /usr/lib/libgnomeui-2.so, may conflict with libpthread.so.20 Just removing libpthread-dev and libpthread20 seems to do the trick - it looks like it is all in the libc package these days. -- [FEISTY] Problems compiling programs with pthread https://bugs.launchpad.net/bugs/81169 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
