Building the Fox

WORK IN PROGRESS

Aim

To build the Mozilla Firefox browser from source code.

Apparatus

Hardware

AMD Athlon XP @ 1.82 GHz 512 MB RAM

Software

• Microsoft® Windows XP® Professional with Service Pack 2.
• Microsoft® Visual Studio .NET 2003® (with C++ module installed).(available from ACS: Disc 0 (Pre-requesite), Disc 1, Disc 2)
• Cygwin
• moztools
• Microsoft ® Windows Server® 2003 R2 Platform SDK
• NSIS Installer
• Make 3.80 (Needed to overwrite make 3.81 which is part of the Cygwin default install)
• 7-zip or similar archiving utility.

Method

Install all software in the default directory unless otherwise specified as it will save time and effort in the long run.

1. Install Visual Studio .NET 2003 (with Visual C++ modules)
2. Install Microsoft ® Windows Server® 2003 R2 Platform SDK
3. Install Cygwin . Remember to install all the package binaries listed below as specified in the Windows Build Pre-requisites made available by the Mozilla Developer Center. To install a package simply expand the desired category and place a check in the bin check box. Source files are not required. Don't worry if you realize you made an error i.e. forgotten a required package. The Cygwin installer is smart enough to accomodate this situation. Simply re-run the Cygwin setup.exe and select the packages you want to add, remove or re-install).:
   • ash -- UNIX-like command line interpreter shell (Base category)
   • coreutils -- GNU core utilities (includes fileutils, install, sh-utils, and textutils) (Base category)
   • cvs -- concurrent versions system (Devel category)
   • diffutils -- file comparison utility (Base category)
   • findutils (Base category)
   • gawk -- pattern matching language (Base and Interpretors categories)
   • grep -- text search tool (Base category)
   • libiconv -- character set conversion (Devel category)
   • make -- dependency analyzer for software builds (Devel category) (Don't worry if it is ver 3.81, we will correct this problem later).
   • patchutils -- a small collection of programs that operate on patch files (Devel category)
   • perl -- a scripting language used to control parts of the build (Interpreters category)
   • sed -- a search and replace language (Base category)
   • unzip -- zip file extraction (Archive category)
   • zip -- zip file creation (Archive category)
4. Install Make 3.80
   1. Download and extract Make 3.80 (make-3.80-1.tar.bz2) to any folder of your choosing. A file named make-3.80-1.tar is created.
   2. Proceed to extract the make-3.80-1.tar file.
   3. Copy the make.exe file located within the usr/bin folder and overwrite the make.exe located in C:\cygwin\bin
   4. To Confirm that the version has changed to 3.80 by launching Cygwin. At the prompt type: make -v
   5. type exit to close Cygwin
5. Download and Extract moztools to a folder of your chosing.
6. Create an batch file containing steps needed to properly configure your build environment prior to proceeding with the build. The contents of the this batch file can be found within the #Batch File section of the #Appendix. Make changes to the batch file as necessary to reflect the different installation paths of the various applications in question. This will ensure that all the environment variables needed for the build to succeed are properly initialized.
7. Rename \bin\link.exe located within the Cygwin installation folder to any different name (e.g. oldlink.exe). This prevents the receipt of an error message stating that the "incremental linker version does not match the compiler suite version" as documented in the Configure the environment section of the Windows Build Pre-requiste guide from the Mozilla Developer Center.
8. Create the c:\proj folder to store the source and object files that will result from the checkout and build respectively.
9. Execute the batch file created in step # 6 above. This should set all the required environment variables and automatically open a cygwin prompt window.
10. Checkout the code.
    1. For the build to work properly we must ensure we are in the c:\proj folder before logging on to CVS to checkout the source files. Issue the following commands at the Cygwin prompt accomplish this:

• • • cd c:
    • cd proj

1. 1. Logon to CVS.
   • At the command prompt type: cvs logon
   • Enter "anonymous" as the password (without the quotes)

Appendix

Batch File

SET CVSROOT=:pserver:anonymous@cvs-mirror.mozilla.org:/cvsroot
SET CVS_RSH=ssh

rem --- Set HOME so that cvs and ssh work correctly
rem --- cvs uses HOME to locate your .cvspass file, and ssh to locate your .ssh file
rem --- if you are using ssh, your HOME should match the home directory specified in /etc/passwd. See http://www.cygwin.com/faq/faq0.html.
set HOME=C:\home

rem --- Set VCVARS to wherever the MSVC vcvars.bat file is found
set VCVARS=C:\Program Files\Microsoft Visual Studio .NET 2003\Vc7\bin\vcvars32.bat

rem --- Set MSSDK to wherever the MS SDK is installed
rem --- Only required for MSVC7 or the Free MSVC editions that don't come with an SDK
set MSSDK=C:\Program Files\Microsoft Platform SDK for Windows Server 2003 R2

rem --- Set MOZ_TOOLS to wherever you have the moztools packaged installed
set MOZ_TOOLS=C:\moztools\moztools-static\moztools

rem --- Set CYGWINBASE to wherever cygwin is installed
rem --- Do not use CYGWIN or else cygserver, cygrunsrv, and Cygwin services will not function properly
rem --- Variable CYGWIN is also used to modify Cygwin's behaviour a little bit.
set CYGWINBASE=C:\cygwin
rem --- Make sure Cygwin does not print out a DOS style path warning
set CYGWIN=nodosfilewarning

rem --- Prepend Cygwin path
rem --- This is necessary so that cygwin find is ahead of windows find.exe in the PATH, but cgywin link is after MSVC link.exe.
set PATH=%CYGWINBASE%\bin;%PATH%

rem --- Set MSVC environment vars
call "%VCVARS%"

rem --- Prepend SDK paths
rem --- Only required for MSVC7 or the Free MSVC editions that don't come with an SDK
set PATH=%MSSDK%\bin;%PATH%
set INCLUDE=%MSSDK%\include;%INCLUDE%
set LIB=%MSSDK%\lib;%LIB%

rem --- moztools comes last
set PATH=%PATH%;%MOZ_TOOLS%\bin

rem --- Now the PATH variable contains:
rem MS-SDK; MSVC; Cygwin; Windows; glib/libIDL; Moztools

rem --- Typically the last thing the script does is launch a cygwin shell
rem --- watch for your ~/.profile and /etc/profile which may overwrite your carefully setup PATH!
bash --login -i
