Include libgit2 in RubyMotion

I am trying to get objective-git included as ruby motion. I tried my best to translate the requirements on objective gits site into what is needed for an OS X ruby motion app. Here is the Rakefile, objective-git is a submodule located in vendor.

# -*- coding: utf-8 -*-
$:.unshift("/Library/RubyMotion/lib")
require 'motion/project/template/osx'

require 'bundler/setup'
Bundler.require :default

Motion::Project::App.setup do |app|
  app.name = 'commit-zero'
  app.vendor_project 'vendor/objective-git', :xcode,
                     xcodeproj: 'vendor/objective-git/ObjectiveGitFramework.xcodeproj',
                     headers_dir: 'vendor/objective-git/External/libgit2/include'
end

Here is the error:

$ rake

Solution

  • Create ObjectiveGit.framework

    $ brew install cmake xctool
$ git clone https://github.com/libgit2/objective-git.git && cd objective-git
$ script/bootstrap
$ xcodebuild

    ObjectiveGit.framework will be generated in build/Release.

    Setup App

    $ motion create TestGit --template=osx && cd TestGit
$ rsync -av path/to/build/Release/ObjectiveGit.framework vendor

    And add following configuration into Rakefile.

    app.embedded_frameworks << 'vendor/ObjectiveGit.framework'
