Description Joerg Schaible 2015-04-01 15:49:04 UTC
After the switch for amd64 multlib systems from the emul-* packages to abi_x86_32, the pipelight plugin no longer works (using wine-1.7.39) in firefox-31.5.3. Silverlight is loaded and using the context menu on the silverlight area works (right mouse click), but the window stays black, a video stream is no longer initiated.

Reproducible: Always

Steps to Reproduce:
1. Install and run a system with firefox-31.5.3/wine-1.7.39/pipelight-0.2.8 based on the emul-* packages. Verify that the plugin delivers the video stream.
2. Unmerge the emul-*-packages, enable abi_x86_32 for any package reported by portage and recompile those packages
3. Reboot to ensure the new packages are used and try to use the pipelight plugin
Actual Results:  
The plugin loads in the browser, but its area stays black, no video stream is initiated.

Expected Results:  
A playing video

Can you run Firefox from console and upload the log?  It should give some useful steps to move forward

Comment 5 Adam Feldman gentoo-dev 2015-04-06 19:46:58 UTC
Can you also post either the last part of `emerge --info wine`  or `eix -Ie wine`

Additionally, what site(s) are you trying, and have you tried other plugins, like flash or unity?

Make sure you have net-libs/gnutls with abi_x86_32; you might then need to rebuild wine to link to it instead of the old emul-* library.
Comment 7 Joerg Schaible 2015-04-07 22:06:51 UTC
The question is, what still references libgnutls.so.26. It seems somewhere is a dependency declaration missing and therefore portage cannot detect the required rebuild.

Comment 8 Alexandre Rostovtsev (RETIRED) gentoo-dev 2015-04-08 08:15:59 UTC
(In reply to Joerg Schaible from comment #7)

To be clear - did rebuilding gnutls and wine fix the pipelight problem?

Unfortunately, there is no way for portage or revdep-rebuid to automatically detect that wine needs to be rebuilt after switching from emul-* to real multilib. This is because wine uses dlopen() to load libgnutls at runtime, and the fact that it will try to open the wrong version of libgnutls cannot be detected by just scanning DT_NEEDED in wine's binaries.
Comment 9 Joerg Schaible 2015-04-08 18:13:19 UTC
OK, I've rebuilt wine again and now it works.

The problem seems to be that the emul-* libraries stay as preserved libs when they are unmerged. Therefore it has no effect for wine, although portage forces a rebuild. Portage removes those libs *after* all the abi_x86_32 have been rebuilt ... to late for wine.
