No pastebins, please. Post/attach all relevant info, reopen then. after chatting with aballier on #gentoo-amd64 we pin-point at "-z, now" it wasn't "--as-needed" nareshov@clueless /mnt/sda7/Music_G/H.I.M $ quodlibet

So don't use such flags. (In reply to comment #5) > So don't use such flags. > Right now that's what I'm doing. LDFLAGS="dancy stuff except <-z, now>" in /etc/portage/env/dev-python/gst-python Thanks anyway. Created attachment 129136 [details]
gst-dlopen-now.c
this should exhibit the same problem on any system
Comment on attachment 129136 [details]
gst-dlopen-now.c
actually, i lied ... ignore this
ugh, looking through gst's python code, it looks like the way they've written their module loading code requires everything be delayed you should get upstream to have configure test and append -Wl,-z,nonow to LDFLAGS when possible -z nonow doesnt seem to properly invert -z now ... -z lazy should work fine You shouldn't be using such flags.. seriously. Anyway, + 01 Sep 2007; Samuli Suominen <drac@gentoo.org> gst-python-0.10.8.ebuild: + Filter some ricing LDFLAGS wrt #168326. me thinks you dont understand what -z,now actually does ... all hardened systems utilize it ... in fact, anyone who wants to be a ricer wouldnt actually utilize these flags as they cause a startup performance problem as a trade off at runtime filtering does not actually solve the problem, you still need to do what i suggested: append -Wl,-z,lazy and get upstream to do the same in the configure script so we dont need to workaround with flag appending Created attachment 129928 [details, diff]
gst-python-0.10.8-lazy.patch
Patch checking if -Wl,-z,lazy is accepted by ld, if yes, then use it.
vapier, looks better? ;)
If someone can be more verbose, for upstream, that'd be nice. URL attached. For reference, gst-python built with -z,now:
