We want to create a standalone application from a GUI created with MATLAB R2015b 64bit. I was told that I need to install a C-compiler and call 'mex -setup' to configure MATLAB using this compiler. However, I could compile a simple test GUI with mcc as well as with the Application Compiler without installation of a C-compiler and running 'mex -setup'.
Can anybody tell me, when the additional C-compiler must be installed? I'd like to know it to avoid problems in the future.
