[FEISTY] Problems compiling programs with pthread

[Christophe Dumez]

Binary package hint: libpthread-dev

Since some time I can't compile some programs (libtorrent, Wormux) anymore, I get this error :

        then mv -f ".deps/ai_engine.Tpo" ".deps/ai_engine.Po"; else rm -f ".deps/ai_engine.Tpo"; exit 1; fi

Probably something changed in libpthread-dev...

Same problem for me. I'm trying to build two applications (Rosegarden and Ardour2) which use this library and both fail with errors like these:

[hectorC (hcengar)]

Also unable to build libgig.

[Christophe Dumez (hydr0g3n)]

I fixed the problem on my system by uninstalling libpthread-dev. Now my programs are compiling just fine. This is odd.

[hectorC (hcengar)]

Very odd, same thing here: uninstalled libpthread-dev and everything compiles fine.

[blaamann (nofancystuff)]

Confirmed.

libpthread-dev breaks building A LOT of application and libs.

For example x264, live555 and Mplayer.

[Dave Gilbert (ubuntu-treblig)]

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.

[Daniel T Chen (crimsun)]

Is this symptom still reproducible in 8.10 alpha with libpth20 and libpth-dev installed?
