I am developing on a PC and a MAC.

My program compiles and runs perfectly on the PC but when I go to build it on the MAC I get a lot of errors which I know aren't causing errors. (If that makes sense.)

Here is the compile output:

Running build steps for project 3DViewer_simplified...

Any and all help would be greatly appriciated.
