[Ves] Compiling VES on iOS

Fri May 23 03:21:09 EDT 2014

Update: I managed to compile by removing the c++11 flag I added.

OK, I don’t know how to go forward with the framework in XCode, the example app doesn’t work either. I tried to manually add to the include path the headers with:

$(PROJECT_DIR)/kiwi.framework/Headers

in the Build Settings, but that breaks OpenCV for some reason. If I don’t, the compiler errors out with:

[…]/kiwi.framework/Headers/vesKiwiBaseApp.h:30:10: 'vesMath.h' file not found with <angled> include; use "quotes” instead
