General / Re: OpenGL example from SFML and macOS Mojave

Yes, the Graphics module works fine, I can compile and run a simple 2D examples from SFML Tutorial book I currently read. But not OpenGL 3D example. Maybe something needs to be change for linker options? I swear they were ok for High Sierra but still.

g++ -Wall -Wpedantic -std=c++17 -o "%e" "%f" -L /System/Library/Frameworks/OpenGL.framework/ -lsfml-graphics -lsfml-window -lsfml-system

General / OpenGL example from SFML and macOS Mojave

« on: November 15, 2018, 01:37:46 pm »

So, I recently encountered a problem that OpenGL example that comes with SFML package can no longer be compiled after upgrade to Mojave 14.1. The thing is, since OpenGL is deprecated in Mojave (why Apple, why?!.) the example no longer works as it is now (I compiled it before, with High Sierra). The compiler first ask to define a macro:

#ifndef GL_SILENCE_DEPRECATION
#define GL_SILENCE_DEPRECATION
#endif

With this, you can compile the cpp file without warnings but when it comes to linker, then there is an error message:

Undefined symbols for architecture x86_64:

What to do, as I am just out of ideas now.
