Building SpiderMonkey with Cygwin <p>I need to build SpiderMonkey so that I can use it with emscripten. I succeeded in building version 1.8 (using the hack from here: <a href="http://pmelson.blogspot.fr/2007/12/building-didier-stevens-spidermonkey-in.html" rel="nofollow">http://pmelson.blogspot.fr/2007/12/building-didier-stevens-spidermonkey-in.html</a>). But unfortunately version 1.8 lacks JSON support and apparently that came into existance with version 1.8.1.</p> <p>Unfortunately I don't see any 1.8.1 tag/branch in CVS and I cannot use version 1.8.5 because the above hack no longer works with that version.</p> <p>Any ideas for getting this to work in Cygwin?</p>
