The mozilla requirement is not satisfied by the mozilla install instructions in this book, but can easily be satisfied by the mozilla build directory created by the instructions. Do not remove <source dir>/mozilla until galeon is installed. Compiling must be done with the same compiler version and the same optimization settings. Install galeon by running the following commands: export SOURCE_DIR=/usr/src && ./configure --prefix=/opt/gnome \ --with-mozilla-libs=/opt/mozilla/lib/mozilla-&mozilla-version; \ --with-mozilla-includes=$SOURCE_DIR/mozilla/dist/include --disable-werror && make && make install
