I'm having an ARC enabled project with the Nimbus library.
I'm having problems building my target with deployment target 4.3
(OS X Mountain Lion, XCode 4.5.1)
.../nimbus/src/core/src/NIOperations.h:53:23: Unknown property attribute '__attribute__'
Unknown property attribute '__attribute__'
.../nimbus/src/core/src/NIPreprocessorMacros.h:138:21: Expanded from macro 'NI_WEAK'
.../<built-in>:128:29: Expanded from macro '__unsafe_unretained'
Seems to be some kind of clang related issue, but I'm not sure how to fix it. Maybe something in the build settings?
Anybody experienced it before? Any suggestion would be appreciated.
