Graphical Web Browsers

Mozilla is a browser suite, the Open Source sibling of Netscape. It includes the browser, composer, mail client, a calendar client and an IRC client.

The Mozilla project also hosts two subprojects that aim to cater to the needs of users who don't need the complete browser suite or like to have seperate applications for browsing and e-mail. These subprojects are Mozilla Firefox, (a stand-alone browser based on the Mozilla source code) and Mozilla Thunderbird, (a stand-alone mail client based on the Mozilla source code). The build instructions for these two applications are discussed in seperate sections:

If you plan to install Enigmail, extract the ipc and enigmail tarballs in the extensions directory.

Compile Mozilla by running the following commands:

export MOZILLA_OFFICIAL="1" &&
export BUILD_OFFICIAL="1" &&
./configure --prefix=/usr \
            --with-default-mozilla-five-home=/usr/lib/mozilla \
            --enable-default-toolkit=gtk2 \
            --with-x --with-system-zlib \
            --with-system-jpeg --with-system-png --with-system-mng \
            --enable-xft --enable-crypto \
            --disable-accessibility \
            --disable-tests --disable-debug \
            --disable-logging --enable-reorder \
            --enable-strip --disable-pedantic \
            --enable-cpp-rtti --enable-extensions=all &&
make

If installing Enigmail, execute the following steps:

build/autoconf/make-makefile extensions/ipc extensions/enigmail &&
make -C extensions/ipc &&
make -C extensions/enigmail

Install Mozilla as follows:

make install &&
install -d /usr/include/mozilla-1.6/nss &&
cp -Lf dist/private/nss/*.h dist/public/nss/*.h \
   /usr/include/mozilla-1.6/nss &&
ln -nsf mozilla-1.6 /usr/include/mozilla &&
ln -nsf mozilla-1.6 /usr/lib/mozilla

Some libraries installed by mozilla are also needed by other packages. These libraries should be in /usr/lib so that other packages can link against these. Move them as follows:

for i in lib{nspr4,plc4,plds4,nss3,smime3,softokn3,ssl3}.so libsoftokn3.chk
do
   mv /usr/lib/mozilla-1.6/$i /usr/lib/
   ln -sf ../$i /usr/lib/mozilla-1.6/
done

Install Enigmail as follows:

make -C extensions/ipc install &&
make -C extensions/enigmail install

To enable multi-user operation, execute the following:

cd /usr/lib/mozilla-1.6 &&
export LD_LIBRARY_PATH="/usr/lib/mozilla-1.6" &&
export MOZILLA_FIVE_HOME="/usr/lib/mozilla-1.6" &&
./regxpcom &&
./regchrome &&
touch `find /usr/lib/mozilla-1.6 -name *.rdf`

Each of these switches can be added to the configure line in order to have the described effect on the Mozilla compile.

--enable-elf-dynstr-gc: Removes un-referenced strings from ELF shared objects generated during the build. Note that this option breaks build on alpha.

--disable-mailnews: Disable the mail and news clients.

--disable-ldap: Disable LDAP Support, recommended if mail is disabled.

--enable-calendar: Build the calendar client.

--enable-xterm-updates: This option is for enabling the xterm title with the current command when compiling.

--enable-plaintext-editor-only: Disable support for HTML editing. Do not use this switch if you are building the mail-news component.

export MOZILLA_OFFICIAL="1" &&
export BUILD_OFFICIAL="1"

Set some variables that affect what and how it is built. The first two exports specify that we are building a distribution.

--prefix=/usr: Previously mozilla did not support the make install option. Hence the package was installed in /opt. The package now supports "make install" and follows the FHS guidelines for installation. Hence the book now recommends installation in a system wide prefix such as /usr .

--enable-toolkit-gtk2

Use gtk2 toolkit

--with-system-zlib --with-system-jpeg \
--with-system-png --with-system-mng

Use the system versions for these packages.

--enable-xft: Enable the Xft support. You need fontconfig or the latest XFree86 version to enable xft.

--enable-crypto: Enable the Personal Security Manager to enable SSL connections.

--disable-jsd --disable-accessibility \
--disable-tests --disable-debug \
--disable-dtd-debug \
--disable-logging --enable-reorder \
--enable-strip \
--enable-cpp-rtti

Various options that affect what components are built and some optimization options. You can pick and choose from these options. More information on them can be found in the Mozilla configure script help. Not all options are used in the instructions given above.

--enable-extensions=...: Enables extensions. If you want, you can disable all extensions other than the browser by changing this switch to --enable-extensions="default,-venkman,-inspector,-irc". For a short description of the various extensions available with the mozilla source, see http://linuxfromscratch.org/~tushar/downloads/mozilla-extensions.txt.

install -d /usr/include/mozilla-1.6/nss
cp -Lf dist/private/nss/*.h dist/public/nss/*.h \
   /usr/include/mozilla-1.6/nss

Copy the nss headers that are not copied by make install.

ln -nsf mozilla-1.6 ...: Mozilla installs headers and libraries in version specific directories. This link makes symbolic links so that applications that depend on Mozilla (such as OpenOffice , Galeon, etc.) don't need to know which version of Mozilla is installed.

export LD_LIBRARY_PATH="/usr/lib/mozilla-1.6" &&
export MOZILLA_FIVE_HOME="/usr/lib/mozilla-1.6" &&
./regxpcom &&
./regchrome &&
touch `find /usr/lib/mozilla-${VERSION} -name *.rdf`

Create the required component registries to enable multi-user installs. These steps should be repeated each time a mozilla add-on is installed as root to allow normal users to run mozilla.

No specific configuration is required as long as the mozilla binary is in the path for the user. If Mozilla is installed in a non-standard location, then make a sym-link to the mozilla binary from /usr/bin. Same thing applies for Mozilla Firefox and Mozilla Thunderbird.

Many applications look for netscape when they need to open a browser. You may make the following symlink for convenience.

ln -sf mozilla /usr/bin/netscape

The Mozilla package contains mozilla .The various components such as composer, mail-news can be accessed from the menu after mozilla starts or via command-line switches to the mozilla binary.
