Guide for using sfml on windows with golang

Credit to https://github.com/DennisPing/Windows-10-Cpp-MinGW64

Initial installs and setup

Run powershell as admin

Prequisites

• Install go https://go.dev/learn/
• Install choco https://chocolatey.org/install

Restart powershell as admin

If you don't use cpp sfml, you only need mingw, tdm compiler also seems to work.

choco install mingw cmake make

Add cmake to path C:\Program Files\CMake\bin

In powershell check versions:

g++ --version
>>  g++.exe (MinGW-W64 x86_64-posix-seh, built by Brecht Sanders) 11.2.0
    Copyright (C) 2021 Free Software Foundation, Inc.

cmake --version
>>  cmake version 3.21.3

make --version
>>  GNU Make 4.3
    Built for Windows32

Download sfml and csfml 2.4 (Currently go-sfml bindings are compatible with 2.4)

• https://www.sfml-dev.org/download/sfml/2.4.0/ Download mingw 64bit
• https://www.sfml-dev.org/download/csfml/

Extract them to where you normally put your libraries, I put mine on D:\libs\x64

Env variables

Add the following env variables to system, change path accordingly on first two, also note I renamed mine to CSFML-2.4, instead of CSFML: Key : Value

CGO_SFML_INCLUDE D:\libs\x64\CSFML-2.4\include
CGO_SFML_LIB D:\libs\x64\CSFML-2.4\lib\gcc
CGO_CFLAGS -I%CGO_SFML_INCLUDE%
CGO_LDFLAGS -L%CGO_SFML_LIB%
CGO_ENABLED 1

CSFML DLLs

Copy csfml from CSFML-2.4\bin to where your main.exe compiled, normally you only need the dlls you're importing.

Build and Run

NB: In powershell

go build .
go run .

main.go

package main

import (
	"runtime"

	"gopkg.in/teh-cmc/go-sfml.v24/graphics"
	"gopkg.in/teh-cmc/go-sfml.v24/window"
)

func init() { runtime.LockOSThread() }

func main() {
	vm := window.NewSfVideoMode()
	defer window.DeleteSfVideoMode(vm)
	vm.SetWidth(800)
	vm.SetHeight(600)
	vm.SetBitsPerPixel(32)

	/* Create the main window */
	cs := window.NewSfContextSettings()
	defer window.DeleteSfContextSettings(cs)
	w := graphics.SfRenderWindow_create(vm, "SFML window", uint(window.SfResize|window.SfClose), cs)
	defer window.SfWindow_destroy(w)

	ev := window.NewSfEvent()
	defer window.DeleteSfEvent(ev)

	/* Start the game loop */
	for window.SfWindow_isOpen(w) > 0 {
		/* Process events */
		for window.SfWindow_pollEvent(w, ev) > 0 {
			/* Close window: exit */
			if ev.GetXtype() == window.SfEventType(window.SfEvtClosed) {
				return
			}
		}
		graphics.SfRenderWindow_clear(w, graphics.GetSfRed())
		graphics.SfRenderWindow_display(w)
	}
}
