I've compiled Firebird on Linux using GCC 3.3.2 with XFT and GTK2 for the Pentium 4 with SSE optimisations. I compiled this build using Fedora Core 0.95. The build is here:
http://pryan.org/firebird/aebrahim/Mozi ... se.tar.bz2 (8.4MB)
This build requires a processor that supports SSE. It will work on Pentium III or better (and derived Celerons), or AthlonXP or better.
I used the following .mozconfig to build:
. $topsrcdir/browser/config/mozconfig
ac_add_options --disable-tests
ac_add_options --disable-debug
ac_add_options --enable-optimize="-O3 -march=pentium4 -msse -mfpmath=sse"
ac_add_options --enable-xft
ac_add_options --enable-default-toolkit=gtk2
My builds have the following preference set:
pref("general.useragent.vendorComment", "aebrahim");
