Documentation for SpiderMonkey is available at:
In particular, it points to build documentation at
Note that the libraries produced by the build system include symbols,
causing the binaries to be extremely large. It is highly suggested that `strip`
be run over the binaries before deploying them.
Building with default options may be performed as follows:
./mach build
This will produce a debug build (much more suitable for developing against the
SpiderMonkey JSAPI). To produce an optimized build:
export MOZCONFIG=$(pwd)/mozconfig.opt
./mach build
You may edit the mozconfig and mozconfig.opt files to configure your own build
appropriately.
