Building SpiderMonkey on Ubuntu

The following instructions for building SpiderMonkey is not specific to Ubuntu, but same on almost all Unix and Unix-like operating systems.

  • Login to Mozilla CVS servers
    • cvs -d :pserver:anonymous@cvs-mirror.mozilla.org:/cvsroot login
  • Pull the sources
    • cvs -d :pserver:anonymous@cvs-mirror.mozilla.org:/cvsroot co -l mozilla/js/src mozilla/js/src/config mozilla/js/src/editline mozilla/js/src/fdlibm
  • And start the build
    • cd mozilla/js/src && make -f Makefile.ref

If your distribution has GCC 4.1, then you might hit on this bug (jscpucfg.c:374: internal compiler error: in dwarf2out_finish, at
dwarf2out.c:14116) during compilation.

You have two ways to fix it:

  • Upgrade to GCC 4.1.2
  • Or, turn on the optimisation flag while compiling
    • CFLAGS=-O2 make -f Makefile.ref

Installation is really simple.

  • sudo mkdir /usr/local/spidermonkey
  • sudo cp Linux_All_DBG.OBJ/{js,jskwgen,jscpucfg,libjs.so} /usr/local/spidermonkey
  • export PATH=$PATH:/usr/local/spidermonkey

Once the installation is done, you can invoke the shell by running js.

    Other way to fix it is by disabling the -g flag in the optimiser in config.mk.
    I was trying to fix this for the past few days.

    How did you find the solution to this problem?

    It was pretty easy to find by searching usenet groups since it seemed to be a well known problem (like the GCC 4.0 visibility problem).
