• What did you do?
  pod install. Along the way, many hopeful signs as indicated by the verbose flag

Comparing resolved specification to the sandbox manifest

• What did you expect to happen?
• What happened instead?

Got this exception. From what digging I can do, it is being triggered from the last line:

installer.rb

              # TODO remove me
              unless pod_dependency_target
                puts "[BUG] DEP: #{dep}"
              end
              pod_target.native_target.add_dependency(pod_dependency_target.native_target)

Because pod_dependency_target is somehow nil(I get the print out BUG] DEP: Eigen)....but how?

Podfile looks like this:

platform :ios                                                               
pod 'BTGraphicsLibrary', :git => 'git@github.com:xxx/graphics.git', :branch => 'ying/podspec'

The podspec for BTGraphicsLibrary looks like this:

{
  "name": "BTGraphicsLibrary",
  "summary": "...",
  "version": "1.0.0",
  "source": {
    "git": "git@github.com:xxx/graphics.git"
  },
  "platform" : "ios",
  "deployment_target" : {
    "ios" : "7.0"
  },
  "dependencies" : {
    "Eigen" : ["~> 3.2"]
  },

  "source_files" : ["include/**/*", "src/**/*", "glm/**/*"],
  "preserve_paths" : "*",
  "xcconfig" : {
    "USER_HEADER_SEARCH_PATHS" : "$(SRCROOT)/BTGraphicsLibrary"
  }
}

More digging - I found out what was wrong.

I have specified the dependency in the podspec as 'Eigen', but the pod is actually 'eigen'. Are cocoapods case sensitive? maybe it should not download the pod in the first place - that would have saved me a bunch of time : ) Either that, or the set_target_dependencies method needs to lowercase everything before comparison.

I actually put a fix for this into Core yesterday that should also apply in this case. Keep it open though, we need test coverage for this for sure.

[vanderneut]

Thanks brightredchilli -- I had the exact same problem. Fixed by changing 'Cocos2D' to 'cocos2d' in my podspec.

@segiddins seems like this is another cause from CocoaPods/Core#231 ?

[segiddins]

Yup, looks like it :(
