How can I include the SVGKit into my Rubymotion project?

Question

I'm trying to use SVGKit in my Rubymotion project but can't seem to get it to build.

So far I've moved the SVGKit code into vendor/SVGKit and added the following to my Rakefile (it's an otherwise blank project)

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

begin
  require 'bundler'
  Bundler.require
rescue LoadError
end

Motion::Project::App.setup do |app|
  app.name = 'SVGKitMotion'
  app.frameworks += %w[ CoreText CoreImage libxml2.dylib QuartzCore CoreGraphics UIKit ]

  app.vendor_project('vendor/SVGKit', :static,
      :products => ["libSVGKit-iOS.1.2.0pre.a"])

end

when I try to build it - I get the following:

Can anybody offer suggestions on where I've gone wrong?

Answer 1

DDLogVerbose is a function from CocoaLumberjack. Your best bet to make this easy would be to install SVGKit via CocoaPods. To do so, first install motion-cocoapods

sudo gem install motion-cocoapods

This should install cocoapods and motion-cocoapods. You need to setup cocoapods so run

pod setup

Now you can add motion-cocoapods to your Gemfile

gem 'motion-cocoapods'

Next add the pod to your rake file

app.pods do
  pod 'SVGKit'
end

Finally run the following rake command to download SVGKit

rake pod:install

Next time you rake, everything should theoretically just compile and work! Good luck :)
