What is this?

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


  1. Window machines. For distcc to be of any use, there should be at least 2 machines
  2. Cygwin. You will need gcc to build distcc. We built using gcc-3.4.4
  3. Mozilla requirements
  4. Patience


Currently, distcc does not transmit debug .pdb files. 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"


The only required environment variable is DISTCC_CL_HOSTS, which contain a space delimited list of all slave machines.

Example : export DISTCC_CL_HOSTS="localhost
