When to generate an executable with xcode, I have 3 Linking errors. I used Irrlicht 1.9 that I compile myself this morning.
I would like to say that the file CIrrDeviceOSX.mm is an objective-c file that can be found here : https://github.com/zaki/irrlicht/blob/master/source/Irrlicht/CIrrDeviceOSX.h https://github.com/zaki/irrlicht/blob/master/source/Irrlicht/CIrrDeviceOSX.mm
I think that the error is inside "std::map KeyCodes;" in CIrrDeviceOSX.h and used in CIrrDeviceOSX.mm
I dont know if the problem is that the file is in objective-c and the signature of the methods is different or that there are difference in version of the C++ (c++11 or ???).
