This is slightly different: I had checked libepoxy0's (and therefore libepoxy0-udeb's) dependencies, both as Debian packages and as ELF binaries, and those are satisfied. libepoxy implements finding libGL internally (through do_dlsym on GLX_LIB, see src/dispatch_common.c, which ends up in turn with dlsym()). > > I'll be poking the libgtk-3-0-udeb bug report to see if we could > > do without pulling libepoxy/libGL… > > Well, that's at least one thing this patch will have been useful to > find out and try to track. > > Thanks a lot for the prompt testing and bug fixing. Bah, you did all the heavy work. I'm only pointing out what isn't working yet. ;) Mraw, KiBi.
