This build was produced on the Sun Java Desktop System Release 2.0 platform, and is compatible with SuSE distributions from 8.1 onwards. It was built to provide GTK2 and xft support for systems still using glibc 2.2, as the supplied Mozilla builds were either GTK2+xlib+glibc2.3 or GTK1+glibc2.2. Since Java Desktop is all GTK2 based, this build provides a far better looking interface. If you encounter any problem with the package, please contact: Mark R. Bowyer . The build is otherwise completely standard, but built from the cvs source tree rather than the mozilla.org supplied source tarball for thunderbird-0.5, as that generated a lot of wierd error messages that stopped configure from running. I grabbed the source tarball from the Mozilla site and then I built with the following .mozconfig file: ---8<--- export MOZ_THUNDERBIRD=1 export BUILD_OFFICIAL=1 export MOZILLA_OFFICIAL=1 ac_add_options --enable-crypto ac_add_options --disable-mathml ac_add_options --disable-installer ac_add_options --disable-activex ac_add_options --disable-activex-scripting ac_add_options --disable-tests ac_add_options --disable-oji ac_add_options --disable-necko-disk-cache ac_add_options --disable-profilesharing ac_add_options --enable-xft ac_add_options --enable-freetype2 ac_add_options --enable-default-toolkit=gtk2 # Note: remove enable-optmize and disable debug if you want a debug build ac_add_options --enable-optimize ac_add_options --disable-debug ac_add_options --disable-profilesharing ac_add_options --enable-extensions=wallet,spellcheck,xmlextras ac_add_options --enable-necko-protocols=http,file,jar,viewsource,res,data # Note: Only include icon for mac, windows and os2 ac_add_options --enable-image-decoders=default,-xbm mk_add_options MOZ_THUNDERBIRD=1 mk_add_options BUILD_OFFICIAL=1 mk_add_options MOZILLA_OFFICIAL=1 ---8<--- and ran: $ export MOZILLA_OFFICIAL=1; $ export BUILD_OFFICIAL=1; $ export MOZ_THUNDERBIRD=1; $ make -f client.mk build_all $ cd xpinstall/packager $ make MOZ_PKG_APPNAME="thunderbird" MOZILLA_BIN="$(DIST)/bin/thunderbird-bin"
