Instructions for building firefox-1.0.6 from source for FC4.

Overview:
=========
A.  Make sure all the prerequisites are there
B.  Compile the source into a binary tarball
        1. obtain source
        2. apply patches
        3. compile (make -f client.mk build)
        4. create binary tarball (make -C obj-i686-pc-linux-gnu/browser/installer)
C.  Turn the binary tarball into an rpm
        1. create environment to build rpms as regular user
        2. Assemble all the necessary files
        3. Build the rpm


Details:
========
A.  Make sure that the prerequisites are present.  (Numbers in parentheses are what I had on my FC4 box)
        -512 MB RAM
        -3 GB free disk space (This is real!  It ate up a huge amount of space)
        -glibc (2.3.5-10)
        -gcc and g++ at least 3.2 or higher (4.0.1-4.fc4)
        -perl 5.6 or higher (5.8.6-15)
        -GNU make 3.79.1  (I had 3.80-7, and it worked fine)
        -CVS 1.11 or higher (1.11.19-8; didn't use it; just downloaded source tarball)
        -gtk2 (gtk2-2.6.7-4)
        -libIDL 0.6.3 - 0.6.8  (0.8.5-2)
                mozilla.org says that libIDL 0.8.x will NOT work
                but it also says that the package ORBit contains libIDL with older version
                so did:  yum install ORBit ORBit-devel
                which installed version 0.5.17-15 of each, which worked fine
        -zip 2.3 or higher (2.3-30)
        -freetype 2.1.0 or higher (2.1.9-2)
        -fontconfig (2.2.3-13)
        -pkgconfig 0.9.0 or higher (0.15.0-6)


B.  Compile the souce into a binary tarball

1.  Obtain the source tarball firefox-1.0.6-source.tar.bz2
    from http://www.mozilla.org/download-mozilla.html
    and unpack it where you have at least 3 GB of disk space.

2.  cd into the top level folder, place the attached patch file
        firefox-mozconfig-oiddatah.patch (attached below, remove the .txt ending)
    just outside the top level folder, and apply the patch by typing:
        patch -p1 < ../firefox-mozconfig-oiddatah.patch
    This patch
        a) adds the configuration file .mozconfig to the folder.  If you look
           at the created .mozconfig, you'll see that it just copies the settings
           found in the standard Fedora build of firefox, by typing about:buildconfig
           in the browser window.
        b) fixes a declaration in oiddata.h (changes something declared as []
           to a pointer.  When declared as [], it produced a fatal compilation
           error).

3.  In the top level folder, issue the command:  make -f client.mk build
    The compilation took about 2 hours on my 1.6 GHz machine.

4.  After the compilation is done, issue this command from the top level folder:
        make -C obj-i686-pc-linux-gnu/browser/installer

    Now, look inside the subdirectory:  mozilla/obj-i686-pc-linux-gnu/dist
    and you will have the binary tarball:
        firefox-1.0.6.en-US.linux-i686.tar.gz

    This binary tarball is what will be used to make the rpm.  Move it someplace
    safe, and then delete the (now enormous) compilation directory.


NOTES:  
Compared to the official binary tarball available from
        http://ftp.mozilla.org/pub/mozilla.org/firefox/releases/
our homemade binary tarball is missing the following files:

    I:  A set of files that will be generated the first time firefox is invoked
        by root.  They will not be generated when invoked by a regular user, because
        the regular user does not have write-access to /usr/lib.  The browser will
        still function normally without these files:
                +/usr/lib/firefox-1.0.6/chrome/overlayinfo/*
                +/usr/lib/firefox-1.0.6/components.ini
                +/usr/lib/firefox-1.0.6/components/compreg.dat
                +/usr/lib/firefox-1.0.6/components/xpti.dat

    II: A set of files involved in "talkback" -- feeding back errors back
        to mozilla.org.  This is not available for home builds.  The browser
        will otherwise function normally without these files:
                +/usr/lib/firefox-1.0.6/components/libqfaservices.so
                +/usr/lib/firefox-1.0.6/components/qfaservices.xpt
                +/usr/lib/firefox-1.0.6/components/talkback/*

    III A set of files involved in processing extensions.  They are
        NECESSARY in order for firefox to process extensions normally.  Why
        they were not generated in the compilation, I have no idea.  Fortunately,
        they are just textfiles, so we will patch them in during the process
        (outlined below) of building an rpm.
                +/usr/lib/firefox-1.0.6/extensions
                +/usr/lib/firefox-1.0.6/extensions/Extensions.rdf
                +/usr/lib/firefox-1.0.6/extensions/installed-extensions-processed.txt
                +/usr/lib/firefox-1.0.6/extensions/{972ce4c6-7e08-4474-a285-3208198ce6fd}
                +/usr/lib/firefox-1.0.6/extensions/{972ce4c6-7e08-4474-a285-3208198ce6fd}/install.rdf
       

C.  Turn the binary tarball into an rpm.  This stuff is lifted straight from
    Thomas Chung's site.  

1.  Make sure you are set up to build rpms as a regular unprivileged user.  
        a) copy/paste the directory /usr/src/redhat into your home directory
           and then make a subdirectory called /tmp:
                $ cp -r /usr/src/redhat /home/yourusername
                $ mkdir -p /home/yourusername/redhat/tmp
        b) Create a textfile with the following contents:
                %packager               Your Name
                %distribution           Fedora Core 4
                %vendor                 yourusername

                %_topdir                %(echo $HOME)/redhat
                %_tmppath               %{_topdir}/tmp
                %_builddir              %{_tmppath}

                %_rpmtopdir             %{_topdir}/%{name}
                %_sourcedir             %{_rpmtopdir}
                %_specdir               %{_rpmtopdir}
                %_rpmdir                %{_topdir}/RPMS
                %_srcrpmdir             %{_topdir}/RPMS
                %_rpmfilename           %%{NAME}-%%{VERSION}-%%{RELEASE}.%%{ARCH}.rpm

           and make sure there is a blank line at the end.
           Save this file as /home/yourusername/.rpmmacros
        c) With this setup, whenever you want to build an rpm called
                name-version-release.arch.rpm
           you will create a folder /home/yourusername/redhat/name.
           Inside this folder you will place the source/binary tarball and specfile.
           And then from inside this folder you will issue the command
                rpmbuild -ba specfile [options]

2.  Create the folder /home/yourusername/redhat/firefox, and put the following
    files into it:
        extensions-folder.patch                        - attached; remove .txt ending
        firefox-1.0.6.en-US.linux-i686.tar.gz        - the binary tarball you built above
        firefox-mathml-enabling.patch                - attached; remove .txt ending
        firefox.desktop                                - attached; remove .txt ending
        firefox.png                                - attached;
        firefox.spec                                - the text of this file follows
#-----------------------------------------------------------------------------------

    Please go through the firefox.spec file and change "Your User Name" on line 3 to
    whatever is appropriate for you.

3.  Build the rpm:  open up a shell, and as regular user,
        $ cd /home/yourusername/redhat/firefox
        $ rpmbuild -ba firefox.spec --target=i686 (or whatever architecture you have)
    This should only take a few minutes

    Your finished rpms should be waiting inside /home/yourusername/redhat/RPMS
    If this works, you can now delete /home/yourusername/redhat/firefox
    Be sure to cleanout /home/yourusername/redhat/tmp

我把他的rpm包下载了，感觉是快了。不过就是中文支持不太好，字体有点不清楚。因为在：
"Edit" -- "references" -"Language" -"Language"里没有simple chinese的缘故吧？不知那位高手可以牺牲点时间重新编译一次，把简体中文编进去，方便一下大家呢？
