Currently, the project is very alpha and exploratory.
Come to #luvmonkey on freenode irc to discuss any questions.
At the moment it's only been tested on Ubuntu.
You need to build spidermonkey on your own. Here are quick instructions.
First download mozilla-central (the repo that contains spidermonkey). If you have good internet, use the mecurial client, if not, you can download a roughly 100mb tarball of the latest revision at http://hg.mozilla.org/mozilla-central
Once downloaded, go to the js folder and build spidermonkey as a static library
cd $HOME/mozilla-central/js/src autoconf2.13 ./configure --disable-shared-js make -j 4 # or however many cores you have
Once you have SpiderMonkey, link it in the deps folder of luvmonkey.
cd $HOME/luvmonkey/deps ln -s $HOME/mozilla-central
Then building luvmonkey is super easy. Simply go to the luvmonkey source tree and do the normal configure;make dance. (Requires python installed since we use gyp)
cd $HOME/luvmonkey ./configure make -j4 # or however many cores you have # Test it ./out/Debug/luvmonkey test.js
