I am using Qualcomm's Vuforia Augmented Reality solution in my iOS project. I integrated their library and files into my application. But, I'm struggled with the build error for long time, couldn't be able to fix it. Attached ref image. The actual error is
Unknown type name 'namespace' in the
Matrices.h file which gets accessed from SampleApplicationSession file. I know this error comes because of C++ access, so we need to rename the extention to .mm file which are trying to access c++ functions. I actually changed the files into .mm including this SampleApplicationSession.mm. But, still I'm getting the namespace error. Could someone please guide me how to fix this?
