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. 1365187 1 mcatanzaro 2017-10-26 18:48:03 -0700 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. 1365190 2 325096 mcatanzaro 2017-10-26 18:51:54 -0700 Created attachment 325096 Patch 1365276 3 cgarcia 2017-10-27 00:07:11 -0700 I don't think we should build pango. We could either bump the glib version, or build gst without pango. 1365357 4 mcatanzaro 2017-10-27 08:24:06 -0700 (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.) 1365394 5 mcatanzaro 2017-10-27 09:57:46 -0700 (In reply to Michael Catanzaro from comment #4) > If that's possible, then this we could do.
