Question

I’m using a SDK in one of my projects and when adding in the libraries etc, I get an error from this line of code, which is from inside a .h file. I cannot change the .m since its not available to me. Its inside .a (lib)

-(enum scanDeviceID)ID; 

And the error message is:

Semantic Issue
ISO C++ forbids forward references to ‘enum’ types

Are there any compilier/build setting that I can modify to make this work?

Failing that, I know very little C++, is there something on the line of code I can change to make it work?

Answer 1

The line of code says that this method returns an element that’s named in the scanDeviceID enum. The problem is that the compiler doesn’t see a declaration of that enum. Somewhere in a .h file you should have that declaration. Importing the file should fix it.
