A build_config.rb to cross-compile mruby for iOS applications.

# cd to your mruby src path
cd ~/Downloads/mruby-1.0.0

# Compile mrbuy with this build_config.rb
MRUBY_CONFIG=(PATH_TO_THIS_REPO)/build_config.rb ./minirake

# Navigate to built libraries
cd build

This should have generated build/iphone-sim, build/iphone-armv7 and build/iphone-armv7s directories. Copy the required libmruby.a from build/iphone-*/lib paths to your projects and enjoy. You only need build/iphone-sim/lib/libmruby.a if you're using the iOS simulator, and don't forget to copy the headers from include/ path as well

To use mruby in a RubyMotion project, do the following:

1. Build mruby as explained above

2. Create a new directory vendor/mruby in your RubyMotion project

3. Copy libmruby.a from build/iphone-sim/lib/libmruby.a to the vendor/mruby directory

4. Copy everything inside include/ dir to you vendor/mruby directory as well

5. Add the following line to your RubyMotion Rakefile

   app.vendor_project('vendor/mruby', :static)

6. Use mruby in your application. For example use this in your app_delegate.rb:

   mrb = Pointer.new(:object) mrb[0] = mrb_open() mrb_load_string(mrb[0], "class TestClass; end") puts mrb_class_defined(mrb[0], "TestClass") # Should output 1 in the console

7. Run rake and look at the console

8. To run on actual devices, you need to copy for build/iphone-armv7/lib/libmruby.a and build/iphone-armv7s/lib/libmruby.a to vendor/mruby as well
