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 build using gcc-3.4.4
- Mozilla requirements
- Patience
Building distcc
Checkout, build, and install the distcc source
svn co svn://cdot.senecac.on.ca/distcc/trunk 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 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_OBJDIR=/cygdrive/c/home/cesar/mozobj ac_add_options --enable-application=browser ac_add_options --enable-optimize ac_add_options --disable-debug ac_add_options --enable-debugger-info-modules=no 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 contains a space delimited list of all slave machines. You must set this variable on the master machine (the machine that contains the source code).
export DISTCC_CL_HOSTS="localhost 10.0.0.2 10.0.0.4"
Distcc Daemon
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.
