I've been trying to solve this for a while and I know something is messed up with the project but maybe someone would have some idea that might help me what am I missing.
Once I'm just adding the new juce_osc module to my project and try to compile (Xcode 7.1 / 10.10.5) I get errors
"No member named 'forward' in namespace 'std' ' , so I guess this is related to some conflict of LLVM.
All the errors are in the juce_OSCMessage, juce_OSCSender headers.
When I do the same to the JuceDemoPlugin it works.
I've compared all the Introjucer settings but cannot see any difference between them.
