OpenGL Corrupt Shader on MAC - c++

Question

I'm trying to run code from the OpenGL book on my Mac (Mojave) and it doesn't work. The errors I'm getting are:
ERROR::SHADER::FILE_NOT_SUCCESFULLY_READ
ERROR::PROGRAM_LINKING_ERROR of type: PROGRAM
ERROR: Compiled vertex shader was corrupt.
ERROR: Compiled fragment shader was corrupt.

Try using an absolute path instead of a relative one.
