What version of Firefox (cset, ideally?) are you using? What version of flash player?

(In reply to :Gijs Kruitbosch from comment #2) > What version of Firefox (cset, ideally?) are you using? What version of > flash player? I pulled source codes form mozilla-central and built them. Version of Flash player is 11.2.202.394. .mozconfig is following: . $topsrcdir/browser/config/mozconfig mk_add_options MOZ_OBJDIR=@TOPSRCDIR@/fx-opt mk_add_options AUTOCONF=autoconf2.13 # Options for 'configure' (same as command-line options). # Enable parallel compiling mk_add_options MOZ_MAKE_FLAGS="-j4" # Avoid dependency on libstdc++ 4.5 ac_add_options --enable-stdcxx-compat # Use ccache ac_add_options --with-ccache=/usr/bin/ccache # Enable Profile-guided Optimization mk_add_options PROFILE_GEN_SCRIPT='$(MAKE) -C $(MOZ_OBJDIR) pgo-profile-run' ac_add_options --enable-profiling # Use gtk3 for default toolkit ac_add_options --enable-default-toolkit=cairo-gtk3 #ac_add_options --disable-crashreporter ac_add_options --without-system-nspr ac_add_options --without-system-nss #ac_add_options --disable-optimize #ac_add_options --enable-debug mk_add_options AUTOCLOBBER=1

plugin-container should not be loading GTK3 libraries. http://hg.mozilla.org/mozilla-central/annotate/0c7eb00d3ef6/ipc/glue/GeckoChildProcessHost.cpp#l542 should mean that libmozgtk2.so is loaded instead of GTK3 libraries. Check that libmozgtk2.so does not depend on GTK3 libraries.

Yes, I can reproduce it, with latest trunk.

I have this too since Aurora was updated to 34. It was working fine before.

Libxul.so directly depends on libgtk-3.so.0. Seems like something screwed up the linking. I've also noticed that the build fails since 34 if the LDFLAGS contain -Wl,--as-needed.

libxu.so is linked with gtk3 (there are -lgtk-3 -lgdk-3 on the linker command line).

I created bug 1063359 for the --as-needed FTBFS.

I don't think the --as-needed is the problem here. Looks like a regression caused by Bug 1045783, which explicitly links libxul.so with the gtk3 libraries. See: http://hg.mozilla.org/mozilla-central/annotate/db7212847c14/toolkit/library/moz.build#l287

See: > > http://hg.mozilla.org/mozilla-central/annotate/db7212847c14/toolkit/library/ > moz.build#l287 It's the exact opposite: that adds all flags from TK_LIBS *except* -lgtk-3 and -lgdk-3.

What does grep gtk-3 $objdir/config/autoconf.mk say?

grep gtk-3 $objdir/config/autoconf.mk: MOZ_GTK3_CFLAGS = -I/home/komat/tmp675-trunk-try/src/widget/gtk/compat-gtk3 -pthread -I/usr/include/gtk-3.0/unix-print -I/usr/include/gtk-3.0 -I/usr/include/at-spi2-atk/2.0 -I/usr/include/gtk-3.0 -I/usr/include/gio-unix-2.0/ -I/usr/include/cairo -I/usr/include/pango-1.0 -I/usr/include/harfbuzz -I/usr/include/pango-1.0 -I/usr/include/atk-1.0 -I/usr/include/cairo -I/usr/include/pixman-1 -I/usr/include/freetype2 -I/usr/include/libdrm -I/usr/include/libpng16 -I/usr/include/gdk-pixbuf-2.0 -I/usr/include/libpng16 -I/usr/include/glib-2.0 -I/usr/lib64/glib-2.0/include MOZ_GTK3_LIBS = -lgtk-3 -lgdk-3 -lpangocairo-1.0 -lpango-1.0 -latk-1.0 -lcairo-gobject -lcairo -lgdk_pixbuf-2.0 -lgio-2.0 -lgobject-2.0 -lglib-2.0

TK_LIBS='$(MOZ_GTK3_LIBS)' doh.

Try removing those single quotes.

I can confirm the patch above fixed the issue for me too.

Comment on attachment 8484848 [details] [diff] [review] Properly link libxul.so on GTK+3 builds after bug 1045783 Why does MOZ_GTK3_LIBS need to be different from MOZ_GTK2_LIBS and MOZ_GTK3_CFLAGS? If the single-quotes break MOZ_GTK3_LIBS, I'd expect it to be similarly broken for those other two variables. It isn't clear why they can't be consistent.

MOZ_GTK3_LIBS needs to be different from MOZ_GTK2_LIBS and MOZ_GTK3_CFLAGS because of http://hg.mozilla.org/mozilla-central/annotate/db7212847c14/toolkit/library/moz.build#l286

Comment on attachment 8484848 [details] [diff] [review] Properly link libxul.so on GTK+3 builds after bug 1045783 Ugh, please document that somehow in configure.in It's really not obvious at all from that file why it should be different.
