Before writing code, ensure your hardware supports OpenGL 3.3.
Because OpenGL functions are loaded at runtime, you cannot call them directly without a loader. Use a library. opengl 3.3 download
Run the following command in the terminal: Before writing code, ensure your hardware supports OpenGL 3
You cannot manually update OpenGL on macOS beyond what Apple provides via OS updates. To ensure OpenGL 3.3: Before writing code
glxinfo | grep "OpenGL version"
sudo apt update sudo apt install mesa-utils sudo ubuntu-drivers autoinstall # For NVIDIA sudo reboot
If your setup is correct, this C++ code should open a window with an OpenGL 3.3 context and clear the screen red.
