=What is this?=

This is a tutorial to get distcc to compile Mozilla Firefox on Windows using cygwin.

=Requirements=

# Window machines. For distcc to be of any use, there should be at least 2 machines

# Cygwin. You will need gcc to build distcc. We ~~built~~ build using gcc-3.4.4

# [http://developer.mozilla.org/en/docs/Windows_Build_Prerequisites Mozilla requirements]

# Patience

=~~Check out and build~~Building distcc=~~TODO : NOTE THE PATCH FOR FIREFOX 2.0 BUILDS~~

Checkout, build, and install the distcc source

'' svn co svn://cdot.senecac.on.ca/distcc/trunk~~''<br>~~'' cd trunk && ./configure && make && make install'' Checkout the Mozilla source. If you are using the latest version of trunk, than you are fine. If you are building 2.0.0.3 or below, you need to apply a silly [https://bugzilla.mozilla.org/show_bug.cgi?id=374563 patch].

=MOZCONFIG=

Currently, distcc does not transmit debug .pdb files(i.e., it can only send back one file). So you cannot currently do a debug build. Here is a sample MOZCONFIG file. All you need to do is modify the object directory (MOZ_OBJDIR).

'''Note the last line''', which is required for any MOZCONFIG file that wants to build using distcc.

mk_add_options MOZ_CO_PROJECT=browser

mk_add_options MOZ_MAKE_FLAGS="CC='distcc cl' CXX='distcc cl' -j4"

-j4 is quite important. According to the man page, you should set the number of jobs equal to the number of all cpus (or cores) + 2.

=Environment=

The only required environment variable is DISTCC_CL_HOSTS, which contain a space delimited list of all slave machines. You must set this variable on the master machine (the machine that contains the source code).

The only required environment variable is ''~~Example :~~'DISTCC_CL_HOSTS''' ~~export DISTCC_CL_HOSTS="localhost 10.0.0.2 10.0~~, which contains a space delimited list of all slave machines.0 You must set this variable on the master machine (the machine that contains the source code).4

export DISTCC_CL_HOSTS="localhost 10.0.0.2 10.0.0.4"

<!--

This section explains some useful environment variables that you can use.

=Distcc Daemon=

~~Start the distcc daemon. The only thing you need to change is who is allowed to use the daemon. You can use space-delimited list of ip addresses, or specify the CIDR mask of an entire subnet.~~

''Start the distcc daemon. The only thing you need to change is who is allowed to use the daemon. You can use a space-delimited list of IP addresses, or specify the CIDR mask of an entire subnet. distccd --allow "'10.0.0.0/24" ' --daemon =Compile Mozilla= You should now be able to compile Mozilla. You won't notice distributing immediately. But you can monitor the progress using the distcc-text or distcc-gnome utility, or using the 'Task Manager'. Sometimes, mozilla forces -j1 in some directories. So be prepared for that. =Complaints= If you feel that these instructions are poorly written, or are having trouble using distcc to compile mozilla because something is unclear, please leave a message in the discussion page. I appreciate any feedback (good/bad) in hopes of improving this documentation. You do not have to leave a contact or your name.
