build.sh

#!/bin/sh

# Shell script for compiling SpiderMonkey for iPhone
#
# 1) Install autoconf 2.13 if you don't have it. You can install it with
#    port install autoconf213, or manually like so:
#    curl -O http://ftp.gnu.org/gnu/autoconf/autoconf-2.13.tar.gz
#    tar xzf autoconf-2.13.tar.gz
#    cd autoconf-2.13
#    ./configure --program-suffix=213 --prefix=/Users/nathano/.local
#    make install
#
# 2) Get the SpiderMonkey source:
#    hg clone http://hg.mozilla.org/mozilla-central/
#
# 3) Dump the files from this gist into mozilla-central/js/src
#
# 4) Run build.sh

if [ ! -f ./configure ]; then
    patch -p0 -i build.patch || exit 1
    autoconf213 || exit 1
