mruby source

  • Clone mruby from GitHub
git clone git://

Android NDK

# Make symlink
ln -s ~/android-ndk-r8c ~/android-ndk
# Make custom standalone toolchain as described here (~/android-ndk/docs/STANDALONE-TOOLCHAIN.html)
cd ~/android-ndk/
build/tools/ --platform=android-14 --install-dir=/tmp/android-14-toolchain
# Export var used by android toolchain cmake file
# Add this line to your ~/.profile file for future use
export ANDROID_STANDALONE_TOOLCHAIN=/tmp/android-14-toolchain

Update 10 Feb 2013:

# Add to your build_config.rb'androideabi') do |conf|
   toolchain :androideabi
