duplicate symbols error when compile

[mafai]

Here's my pod file config, I have tried 2.3 and 2.4 version, but none of them works.

platform :ios, '7.0' pod 'ECSlidingViewController', '~> 2.0.1' pod 'AFNetworking', '~> 2.2.1'

pod 'FMDB', '~> 2.3'

pod 'FMDB', '~> 2.4'

Here's the detail output when do the compile. No idea how to solve it, anyone can help ?

Try doing a rm -rf Pods; pod install, then a Clean -> Build in your project.

Also, with CocoaPods, you don't need to manually link the libraries to your projects, let CococaPods manage your dependencies for you.

Oh, and you might want to try to cleanup your DerivedData folder: rm -rf ~/Library/Developer/Xcode/DerivedData

I try both as you suggested. But still get the same error. I just start a new complete new Project, and did not link any library manually.

➜  ~  rm -rf ~/Library/Developer/Xcode/DerivedData 

➜  FMTest  rm -rf Pods; pod install

The problem solved, after the pod version from 0.32.1 to 0.34.1 version.
