Getting started

Compile on Windows

1. Install msys2 (because we need mingw64, gcc and libws2_32.a)
2. Open msys2 or mingw64 and run pacman -S mingw64/mingw-w64-x86_64-mruby
3. Get MRuby and extract the folder
4. Run make inside the folder mruby-3.3.0, there will be a new folder called /build after the compilation, we need the file at /build/host/lib/libmruby.a
5. Compile using the following command gcc main.c -I"mruby-3.3.0/include" "mruby-3.3.0/build/host/lib/libmruby.a" "C:\msys64\mingw64\lib\libws2_32.a" -lm -o main or substitue "C:\msys64\mingw64\lib\libws2_32.a" with -lws2_32
6. Run the compiled binary main.exe
