this is what i'm using so far to build xulrunner with GCC 4.3 svn. The preprocessor in 4.3 is a lot more strict for C++, turning most -pendantic warnings into errors. xulrunner has a couple places where NS_DECL_IMGIENCODER is redefined which is no longer allowed. (see http://www.cyrius.com/journal/gcc/gcc-4.3-pedwarn.html). this patch is from opensuse (http://lists.opensuse.org/opensuse-commit/2007-11/msg00823.html) and was originally for firefox-2.0.0.10, so it should be applicable to most mozilla stuff with minor changes. i think xulrunner HEAD (or whatever will be 1.9) builds with GCC 4.3, so if that will be released any time soon we might just want to wait. there is one other problem, a conflict between popt and glib that has to be fixed first before xulrunner will build completely. but that has nothing to do with you guys ;) x86_64-pc-linux-gnu-g++ -o nsIconChannel.o -c -fvisibility=hidden -DMOZILLA_INTERNAL_API -D_IMPL_NS_COM -DEXPORT_XPT_API -DEXPORT_XPTC_API -DEXPORT_XPTI_API -D_IMPL_NS_COM_OBSOLETE -D_IMPL_NS_GFX -D_IMPL_NS_WIDGET -DIMPL_XULAPI -DIMPL_NS_NET -DOSTYPE=\"Linux2.6\" -DOSARCH=\"Linux\" -DBUILD_ID=2008010622 -DORBIT2=1 -pthread -I/usr/include/libgnomeui-2.0 -I/usr/include/libart-2.0 -I/usr/include/gconf/2 -I/usr/include/gnome-keyring-1 -I/usr/include/libgnome-2.0 -I/usr/include/libbonoboui-2.0 -I/usr/include/libgnomecanvas-2.0 -I/usr/include/gtk-2.0 -I/usr/include/gnome-vfs-2.0 -I/usr/lib64/gnome-vfs-2.0/include -I/usr/include/orbit-2.0 -I/usr/include/glib-2.0 -I/usr/lib64/glib-2.0/include -I/usr/include/libbonobo-2.0 -I/usr/include/bonobo-activation-2.0 -I/usr/include/libxml2 -I/usr/include/pango-1.0 -I/usr/include/freetype2 -I/usr/include/gail-1.0 -I/usr/include/atk-1.0 -I/usr/lib64/gtk-2.0/include -I/usr/include/cairo -I/usr/include/libpng12 -I../../../../../dist/include/xpcom -I../../../../../dist/include/string -I../../../../../dist/include/necko -I../../../../../dist/include/intl -I../../../../../dist/include/mimetype -I../../../../../dist/include/imgicon -I../../../../../dist/include -I/usr/include/nspr -I../../../../../dist/sdk/include -fPIC -DGENTOO_NSPLUGINS_DIR=\"/usr/lib64/nsplugins\" -DGENTOO_NSBROWSER_PLUGINS_DIR=\"/usr/lib64/nsbrowser/plugins\" -fno-rtti -fno-handle-exceptions -Wconversion -Wpointer-arith -Wcast-align -Woverloaded-virtual -Wsynth -Wno-ctor-dtor-privacy -Wno-non-virtual-dtor -Wno-long-long -g -march=native -pipe -fPIC -Wno-return-type -w -fshort-wchar -pthread -pipe -DNDEBUG -DTRIMMED -ffunction-sections -O2 -DGENTOO_NSPLUGINS_DIR=\"/usr/lib64/nsplugins\" -DGENTOO_NSBROWSER_PLUGINS_DIR=\"/usr/lib64/nsbrowser/plugins\" -DMOZILLA_CLIENT -include ../../../../../mozilla-config.h -Wp,-MD,.deps/nsIconChannel.pp nsIconChannel.cpp In file included from /usr/include/libbonobo-2.0/bonobo/bonobo-i18n.h:39, from /usr/include/libgnome-2.0/libgnome/gnome-i18n.h:41, from /usr/include/libgnome-2.0/libgnome/libgnome.h:30, from nsIconChannel.cpp:43: /usr/include/glib-2.0/glib/gi18n.h:30:1: error: "N_" redefined In file included from /usr/include/libgnome-2.0/libgnome/gnome-program.h:41, from /usr/include/libgnome-2.0/libgnome/libgnome.h:29, from nsIconChannel.cpp:43: /usr/include/popt.h:161:1: error: this is the location of the previous definition gmake[4]: *** [nsIconChannel.o] Error 1 gmake[4]: Leaving directory `/var/tmp/portage/net-libs/xulrunner-1.8.1.11/work/mozilla/modules/libpr0n/decoders/icon/gtk'
Created attachment 140355 [details, diff] xulrunner-1.8.1.11-gcc-4.3.patch
Fixed in patchset 0.2. So i believe everything else (firefox, thunderbird) fail at the moment? Thanks for the patch!
