SDL2 quick and dirty setup on Windows and MinGW

• Download development library from https://www.libsdl.org/download-2.0.php
• From extracted SDL2/i686-w64-mingw32/include folder, copy the SDL2 folder to your project/include (so that inside your project you will have include/SDL2).
• From SDL2/i686-w64-mingw32/bin folder, copy SDL2.dll to your project root.
• From SDL2/i686-w64-mingw32/lib folder, copy libSDL2main.a to your project root.

In your project root, create main.cpp with this code:

SFML in Xcode using project template and frameworks

• Download SFML for Mac from: https://www.sfml-dev.org/download.php
• From extracted folder, copy contents of Frameworks and extlibs folders to /Library/Frameworks.
• From extracted folder, copy templates folder to ~/Library/Developer/Xcode/Templates.
• Create new project with SFML template and select using of Frameworks instead of dynamic libraries.
• If building fails, go to Build phases and select For install builds only.

Python virtual environment installation

• sudo apt install python3-pip --fix-missing
• pip3 install virtualenv
• nano ~/.profile and add the location to path, copy paste this kind of line in the end of the file: PATH="$PATH:/home/mikal/.local/bin" or wherever it is located. After installation, virtualenv lets you know the location.
• Now you can create virtual environment using virtualenv venv
• Activate your environment using source venv/bin/activate and you will see (venv) appearing in front of your command prompt.
