Adding "-lpthread" for linking in sigc++ is enough but I don't know where in the original Makefile this belongs.
Created attachment 101467 [details, diff] libsigc++-1.0.4-r3.ebuild patch This ebuild has many problems: 1) the as-needed problem 2) problem to cross-compile 3) problem with keeptemp/keepwork This patch should fix all the problems

drizzt, you posted the ebuild patch, but not the as-needed patch.
The build failure was in the tests, so I've just removed them altogether. They were never really used. Fixed in cvs without a revbump.
Bleh... I shouldn't have opened my mouth. They are used, I've just disabled them for now. Real fix on its way.
Ok so this is fixed for real. Here's the fix : # fix --as-needed, see bug #140248 sed -i -e 's:^libsigc_la_LIBADD =:& $(THREAD_LIB):' \ sigc++/Makefile.in || die I tried doing it properly with a real patch to Makefile.am, but the configure.in is _really_ old, and does a lot of crappy things. Fixing it all was not worth it for a package which is used by maybe 5 other ebuilds that should be treecleaned. So I'm lazy and did this instead, pretty much like Timothy's patch. Again, fixed without a revbump. Cheers
