motion-cocoapods and TouchDB

[Jim Rankin]

I think it would be cool to use TouchDB with RubyMotion, particularly the synchronization possibilities.

Unfortunately, I have not been able to get the TouchDB CocoaPod to build with motion-cocoapods.

I created a test project:

motion create TouchTest

My Gemfile:

    

source "https://rubygems.org"

gem 'motion-cocoapods'

My Rakefile:

# -*- coding: utf-8 -*-

$:.unshift("/Library/RubyMotion/lib")

require 'motion/project'

require 'bundler'

Bundler.require

Motion::Project::App.setup do |app|

  # Use `rake config' to see complete project settings.

  app.name = 'TouchTest'

  app.pods do

    pod 'TouchDB', '~> 0.961'

  end

end

I get a bunch of errors related to release not being available in reference counting mode:

/Users/jimbo/projects/ruby-motion/TouchTest/vendor/Pods/CocoaLumberjack/Lumberjack/DDAbstractDatabaseLogger.m:118:3: error: 'release' is unavailable: not available in automatic reference counting mode

                dispatch_release(saveTimer);

                ^

/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator6.0.sdk/usr/include/dispatch/object.h:183:35: note: expanded from macro 'dispatch_release'

                _dispatch_object_validate(_o); [_o release]; })

                                                ^

(several more similar errors)

I also get errors because dispatch_get_current_queue() is deprecated:

/Users/jimbo/projects/ruby-motion/TouchTest/vendor/Pods/CocoaLumberjack/Lumberjack/DDAbstractDatabaseLogger.m:206:6: warning: 'dispatch_get_current_queue' is deprecated: first deprecated in iOS 6.0 [-Wdeprecated-declarations]

        if (dispatch_get_current_queue() == loggerQueue)

            ^

Setting deployment_target to 5.1:

Motion::Project::App.setup do |app|

  # Use `rake config' to see complete project settings.

  app.name = 'TouchTest'

  app.deployment_target = "5.1"

  app.pods do

    pod 'TouchDB', '~> 0.961'

  end

end

gives me different errors:

duplicate symbol _OBJC_IVAR_$_TDReachability._hostName in:

    /Users/jimbo/projects/ruby-motion/TouchTest/vendor/Pods/build-iPhoneSimulator/libPods.a(TDReachability.o)

    /Users/jimbo/projects/ruby-motion/TouchTest/vendor/Pods/build-iPhoneSimulator/libPods.a(TDReachability_Stubs.o)

From the little bit of research I did, I'm pretty sure in this case the _Stubs version is meant for the GNUStep implementation, and motion-cocoapods is missing whatever cues there are in the CocoaPod to ignore this file.

Interestingly, if I open vendor/Pods/Pods.xcodeproj in XCode, I can build the "iPhone 6.0 Simulator" target without incident.  This is why I think the issue is not with the TouchDB CocoaPod, but with how it's interpreted by motion-cocoapods.

Ideas about what else I can try?  Do you think this is salvageable, or have I slipped off the bleeding edge here?  (TouchDB about to go 1.0, RubyMotion, and motion-cocoapods all still in flux and very new, so not surprising there are issues.)

Is there any way to better control what files are compiled by motion-cocoapods?  Should I report this as an issue on motion-cocoapods?

Anyone else interested in using TouchDB with RubyMotion?

Thanks in advance,

Hi Jim, 

I am interested in using touchdb with rubymotion, did you get this working?

I would love to follow up with you and know what your take on using touchdb with rubymotion.
