spidermonkey

The SpiderMonkey JavaScript VM buildable on Android and iOS.

Demo

http://folecr.github.com/hellojs-android

Build

Prerequisistes

All platforms
  • autoconf213
iOS
  • Xcode >= 4.3.1
Android
  • Android NDK

How to

iOS

Precompiled version
  • Download the precompiled version
  • Uncompress and place the files inside a 'libs' directory in your project (or anywhere you want)
  • Add the proper header and libs search path to your target
  • Also add the "-ljs_static" linker flag
Compile your own version
cd spidermonkey/js/src
autoconf213
cd build-ios
sh build_ios_fat.sh
file libjs_static.a
> libjs_static.a: Mach-O universal binary with 2 architectures
> libjs_static.a (for architecture i386):	current ar archive random library
> libjs_static.a (for architecture armv7):	current ar archive random library

After that you would get a fat (i386 + armv7) library named libjs_static.a and a directory named dist, full of symlinks. To use that you can just cp -RL the dist directory and place it wherever you want:

cp -RL dist ~/Desktop/testmonkey/libs/spidermonkey

Then, in your iOS app, make sure you add the right header search path (libs/spidermonkey/include) and lib search path (libs/spidermonkey/libs) and add the linker flag "-ljs_static".

Android

> mkdir mozilla && cd mozilla
> git clone git://github.com/folecr/spidermonkey.git
> cd spidermonkey/js/src
> autoconf213
> cd build-android
> sh build.sh

Produces a static ARM library in

mozilla/spidermonkey/dist/lib

Include files are in

mozilla/spidermonkey/dist/include

Android NDK module is at

mozilla/spidermonkey/android/Android.mk

You can now use this module in your Android NDK project by including this in your Application.mk

$(call import-module,spidermonkey/android)

and adding the path to the mozilla directory to NDK_MODULE_PATH

NDK_MODULE_PATH=mozilla

For an example application that will run JavaScript scripts on your Android device see http://folecr.github.com/hellojs-android.

Enjoy!
