mruby-leapmotion

mruby-leapmotion wrapped 'LeapSDK'.

Supported platforms


  • Ubuntu 12.04 LTS
  • Mac OS X
  • Windows

How to build


  1. download and extract LeapSDK
  2. edit your 'build_config.rb'
  3. set library path to load a library contained into LeapSDK (libLeap.so, libLeap.dylib).
  4. run 'make' command.

for Ubuntu

build_config.rb:

conf.gem :github => 'crimsonwoods/mruby-leapmotion', :branch => 'master'

conf.cxx do |cxx|
  cxx.include_paths << "/path/to/your/LeapSDK/include"
end

conf.linker do |linker|
  linker.libraries << %w(stdc++ m Leap)
  linker.library_paths << "/path/to/your/LeapSDK/lib/<platform>/"
end

for Mac

build_config.rb:

toolchain :clang

...

conf.gem :github => 'crimsonwoods/mruby-leapmotion', :branch => 'master'

conf.cxx do |cxx|
  cxx.flags << "-stdlib=libc++"
  cxx.include_paths << "/path/to/your/LeapSDK/include"
end

conf.linker do |linker|
  linker.libraries << %w(c++ mLeap)
  linker.library_paths << "/path/to/your/LeapSDK/lib/libc++/"
end

for Windows

build_config.rb:

toolchain :vs2012

...

conf.gem :github => 'crimsonwoods/mruby-leapmotion', :branch => 'master'

conf.cxx do |cxx|
  cxx.include_paths << "X:\\path\\to\\your\\LeapSDK\\include"
end

conf.linker do |linker|
  linker.libraries << %w(Leapd)
  linker.library_paths << "X:\\path\\to\\your\\LeapSDK\\lib\\<platform>"
end

Restrictions

for Windows

  1. Use 'Leapd.dll' (for debug) instead of 'Leap.dll'. Release version DLL is not working currently.

Sample


Sample code is contained into 'sample' directory.

How to run


  1. connect your Leap Motion
  2. wait for chaning, the color of indicator will be green.
  3. set LeapSDK library path to 'LD_LIBRARY_PATH' (use 'DYLD_LIBRARY_PATH' instead for Mac).
  4. run mruby with sample code or your code.
