Description Götz Waschk 2008-10-17 09:41:02 UTC 
This is on Mandriva Cooker with libepc 0.3.6. The default linker flags contain --no-undefined and --as-needed:

Comment 1 Murray Cumming 2008-10-17 10:02:25 UTC 
Weird. This version added a check for gthread in configure.ac. Could you try to produce a patch to fix this, please?
Comment 2 Götz Waschk 2008-10-17 10:11:16 UTC 
Sure. My current workaround is to call make LIBS=-lgthread-2.0.

gthread was not added to the examples linker flags, only to the flags of libepc.la.

libepc_examples_build.patch

Does this one fix it too? It seems simpler to me.
Comment 5 Götz Waschk 2008-10-19 11:12:43 UTC 
Your patch is fine too.
Comment 6 Murray Cumming 2008-10-19 11:46:20 UTC 
Thanks. I have committed that and I have released a new tarball.
