Assignment 1 - Building the Fox

Written By Mark Paruzel.
THIS IS UNDER CONSTRUCTION!!

Introduction

I have built Firefox before for a previous assignment I did and it was dead simple. Building Firefox 3.0 is as easy as riding a bike; building Firefox 1.5 is like attempting to start a fire, 30 feet under water. Its painful. So, hopefully these instructions will make it a bit easier then the instructions available on the MDC.

Required Software

  1. Microsoft Visual Studio 2003 (MSVC 7.1)
  2. Cygwin
  3. Make 3.80 for Cygwin
  4. Moztools & Wintools
  5. Patience!!!

Build Instructions

Visual Studio 2003

  • Visual Studio is available at the school ACS office/website so you can grab it from there and install it. Its easy to install it because the installer is idiot proof. This shouldn't be hard :).

Cygwin

  • Cygwin is avilable for download Here. Install it with the following tools:
    • ash -- UNIX-like command line interpreter shell (Base category)
    • coreutils -- GNU core utilities (includes fileutils, sh-utils, and textutils) (Base category)
    • diffutils -- file comparison utility (Base category)
    • findutils (Base category)
    • gawk -- pattern matching language (Base and Interpretors categories)
    • grep -- text search tool (Base category)
    • make -- dependency analyzer for software builds (Devel category)
    • 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)

Make 3.80

  • Unfortunately, Cygwin no longer is bundled with make 3.80, rather its bundled with 3.81-1 which breaks duing the Firefox build.
  • To get the version of make that works (3.80), you have to download it here. Once you have download it, you can just grab the Make executable file (make.exe) from /usr/bin/ directory and drop it into Cywgin/bin (this will overwrite the existing Make executable).
  • While your doing this, make sure Cygwin is not running. If it is, you will need to restart Cygwin.

Setting Up Your Build Directory

  • Start up Cygwin and navigate to your C drive:
$> cd /cygdrive/c/
$> pwd
/cygdrive/c
  • We need to create a place where we will do all our development. I used a directory called proj:
$> mkdir proj
$> cd proj
$> pwd
/cygdrive/c/proj
  • Inside this directory, we will put all of our tools and batch files we will use to setup the build environment:
$> touch buildsetup.bat
  • The buildsetup.bat will set up the environment variables for us, which we will do in a different section.

Moztools And Wintools

  • There are two tool packages that are required to build Firefox using VS 7.1. These two tools are called Moztools and Wintools.
  • Download these two zip files and extract thier contents into your C:\proj\ directory.
$> pwd
/cygdrive/c/proj
$> ls -al
drwx------+  6 RealMarkP       None         0 Oct 12 15:13 .
drwxrwxr-x+ 10 Administrators  SYSTEM       0 Oct 13 11:23 ..
-rwx------+  1 RealMarkP       None       843 Oct 12 15:08 buildsetup.bat
drwx------+  5 RealMarkP       None         0 Jan 23  2001 buildtools
drwx------+  5 RealMarkP       None         0 Jan 24  2006 moztools
  • At this point were technically done with this section, installing these two tools will be handled in a later section.

Setting Up The Environment

  • The Cygwin Environment is basically set up and the two tool packages are extracted. You now have the tools required to automate the build process as well as the compiler to do the grunt work.
  • Before you can start to build, you need to set up a bunch of environment variables so that the make files know where to look for dependencies. I created a build batch file that set up the environment for me:
@echo off

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

rem --- Setup the paths to the moztools build librariesset
set MOZ_TOOLS=C:\proj\moztools
set GLIB_PREFIX=c:\proj\vc71
set LIBIDL_PREFIX=c:\proj\vc71

rem --- Scrub these variables first
SET INCLUDE=
SET LIB=
SET PATH=C:\;C:\windows\system32;C:\windows\system32\wbem

rem --- Prepend cygwin
SET PATH=C:\cygwin\bin;%PATH%

rem --- Setup VC8 compiler environment vars
CALL "C:\Program Files\Microsoft Visual Studio .NET 2003\Vc7\bin\vcvars32.bat" x86

rem --- Add glib/libidl to build environment
SET PATH=%PATH%;%GLIB_PREFIX%;%GLIB_PREFIX%\bin
SET INCLUDE=%GLIB_PREFIX%\include;%INCLUDE%
SET LIB=%GLIB_PREFIX%\lib;%LIB%

rem --- moztools comes last after glib/libIDL
SET PATH=%GLIB_PREFIX%;%GLIB_PREFIX%\bin;%PATH%;%MOZ_TOOLS%\bin
  • It should be noted that there are several lines that point to C:\proj\VC71, this is alright because we will install those in the enxt section.

Glib And LibIDL For VC 7.1

  • Unfortunately, Moztools cones with an out dated version of Glib and LibIDL, therefore we have to supply our own. The following versions of Glib and libIDL are for Visual Studio 7.1.
  • Grab these two files and extract them into the proj directory. If done correctly they should be a directory called VC71 in your C:\proj directory.
$> pwd
/cygdrive/c/proj
$> ls -al
drwx------+  6 RealMarkP       None         0 Oct 12 15:13 .
drwxrwxr-x+ 10 Administrators  SYSTEM       0 Oct 13 11:23 ..
-rwx------+  1 RealMarkP       None       843 Oct 12 15:08 buildsetup.bat
drwx------+  5 RealMarkP       None         0 Jan 23  2001 buildtools
drwx------+  5 RealMarkP       None         0 Jan 24  2006 moztools
drwx------+  6 RealMarkP       None         0 Apr  5  2004 vc71
  • At this point, you are ready to set up the environment variables so that the build process knows where to look.

Environment Variables

  • The first thing that needs to be done, is to jump into the DOS command prompt.
$> cmd.exe
C:\proj>
  • Note: All the unix commands work perfectly in this state because the DOS command prompt inherited all the environment settings of the Cygwin shell.
  • Firstly, we need to run the buildsetup batch file we created earlier in order to set up any environment variables we need.
C:\proj>buildsetup.bat
Setting environment for using Microsoft Visual Studio .NET 2003 tools.
(If you have another version of Visual Studio or Visual C++ installed and wish
to use its tools from the command line, run vcvars32.bat for that version.)

C:\proj>
  • In order to test and see if this worked, you can display all the variables that were changed and see if they contain the necessary paths for the build to work.
C:\proj>echo %PATH%
c:\proj\vc71;c:\proj\vc71\bin;C:\Program Files\Microsoft Visual Studio .NET 2003\Common7\IDE;C:\Program Files\Microsoft Visual Studio .NET 2003\VC7\BIN;C:\Program Files\Microsoft Visual Studio .NET 20
03\Common7\Tools;C:\Program Files\Microsoft Visual Studio .NET 2003\Common7\Tools\bin\prerelease;C:\Program Files\Microsoft Visual Studio .NET 2003\Common7\Tools\bin;C:\Program Files\Microsoft Visual
Studio .NET 2003\SDK\v1.1\bin;C:\WINDOWS\Microsoft.NET\Framework\v1.1.4322;C:\cygwin\bin;C:\;C:\windows\system32;C:\windows\system32\wbem;;c:\proj\vc71;c:\proj\vc71\bin;C:\proj\moztools\bin
  • What you should be looking for is the if C:\proj\vc71 is in the path as well as C:\proj\moztools. These two paths are crucial to the build.
C:\proj>echo %GLIB_PREFIX%
c:\proj\vc71

C:\proj>echo %LIBIDL_PREFIX%
c:\proj\vc71

C:\proj>echo %MOZ_TOOLS%
C:\proj\moztools

C:\proj>
  • Secondly, in order to install Wintools into the Moztools, we need to navigate into that directory and install using the batch file provided.
C:\proj>cd buildtools
C:\proj\buildtools>cd windows
C:\proj\buildtools\windows>install.bat

MOZ_TOOLS is set to C:\proj\moztools

copying exes and dlls to C:\proj\moztools\bin
copying include files to C:\proj\moztools\include
copying include files to C:\proj\moztools\include\libIDL
copying lib files to C:\proj\moztools\lib

done copying

make sure that MOZ_TOOLS\bin is on your path

C:\proj\buildtools\windows>cd ../..
C:\proj>
  • This copies over any windows related tools that we need for the build.
  • The environment is now set up to recieve and compile the mozilla source tree.

Pulling From CVS

  • Now the easy part begins. In order to pull from the CVS repository, you have to specify the right type of branch to pull, this is done by the following command.
C:\proj>cvs -d :pserver:anonymous:anonymous@cvs-mirror.mozilla.org:/cvsroot co -r MOZILLA_1_8_0_BRANCH mozilla/client.mk
  • We are going to pull the 1.8.0 branch because thats the branch that corresponds with the Firefox 1.5 build.
  • This creates a mozilla directory with a cile called client.mk inside it. this file is a make file script that defines what to pull and how.
  • To pull the source from the CVS, just use this command.
C:\proj>cd mozilla
C:\proj\mozilla>make -f client.mk checkout
  • Once its done, we need to make a file called mozconfig that will specify the parts of the system that will be built. Put the following code inside this file using notepad or similar text processor. This file does not have an extension and is plainly called mozconfig.
mk_add_options MOZ_CO_PROJECT=browser
mk_add_options MOZ_OBJDIR=@TOPSRCDIR@/hopefullyWorked.firefox.optimized
ac_add_options --enable-application=browser
ac_add_options --disable-optimize
ac_add_options --enable-debug
ac_add_options --enable-svg
ac_add_options --enable-canvas
ac_add_options --disable-installer
  • Next, all we have to do is Build!!

Conclusion

It took me almost a week to figure out what to pull from CVS, setting up the environment variables, build, finding what i did wrong and rebuilding 6 more times...In other words, it was a pain. Fortunately, Firefox got built so now I can get on with trying to run it through the VS Debugger.
