Hello,

Starting from latest vlc-0.8.6f-8.1.src.rpm package from D. Leuenberger, I recompiled it after some openSUSE 10.3 packages updates.

Whenever I want to play something, the item appears under "general" in the playlist but nothing happens. I have relaunched vlc with traces options and I got these ones :

Original vlc package from videolan repository works great. After wxwidgets messages, normal traces show :

This is surely a distro related problem but maybe not : it could be a weakness around thread and/or signal management. I have no clue to continue further.

You must configure vlc options with NO Portable GNU threads library and NO State Threads Library enabled : vlc 0.8.6f does not manage correctly object locking. Whether you use portable thread or state thread library, you got a deadlocked playlist.

So, I have changed packager's vlc.spec according to this :

--disable-pth
--disable-st

Note to the videolan packager : it seems you enable both portable threads and state threads configure options which is non sens since first : only one threading system should be used and second : it leads to a link error whenever you have both installed libraries.

Indeed, when both options are enabled, you take into account both pth.h and st.h headers at compilation time, but only -lst flag is taken into account and not -lpth flag at link time.

You got only a package binary which works because no threads library is installed into your build environment. Both are silently disabled at compile time by configure checking.

Hello,

indeed, those two flags are ignored and I did not even realize it. I removed them from the spec and any upcoming version of the vlc packages will have the spec file corrected in the src rpms.

Thanks for the info
