Reported 2017-10-26 18:33:00 PDT
When trying to run dyz inside our jhbuild environment, I see the following error: (gst-plugin-scanner:16711): GStreamer-WARNING **: Failed to load plugin '/home/mcatanzaro/Projects/WebKit/WebKitBuild/DependenciesWPE/Root/lib/gstreamer-1.0/libgstpango.so': /lib64/libpango-1.0.so.0: undefined symbol: g_log_structured The problem is that pango is missing from our jhbuild environment. The modulesets will never work reliably if we have system libraries in the middle of our dependency graph, since they will sometimes depend on newer versions of libraries than we have inside the jhbuild.

Specifically, in this case, our glib is so old that it does not contain the structured logging support required by my system copy of pango.

I don't think we should build pango. We could either bump the glib version, or build gst without pango.

(In reply to Carlos Garcia Campos from comment #3) > I don't think we should build pango. We could either bump the glib version, That's not good enough, it will break again in the future. The jhbuild environment has to be complete or it won't be reliable. > or build gst without pango. If that's possible, then this we could do. Let me check. (Anyway, I have absolutely no clue why GStreamer could possibly depend on pango.)
