SDL2 version: N/A
OS: Windows 11

When i run my go-sdl2 code i get the error:"

and my code is ```go
package main

)

func run() error {

if err != nil {

Hi @vtf6259, could you show me how you build the code that generated the error?

[vtf6259]

@veeableful it is go build main.go and i do go mod tidy to install go-sdl2

[veeableful]

Thanks @vtf6259! Would it compile if you remove usage of ttf from the code? Perhaps put only sdl.Delay(16) in the main() function.

Oh and how did you install SDL2 and SDL2_ttf? Are you using MinGW?

[vtf6259]

@veeableful to install SDL2 and SDL2_ttf i use go mod tidy

[veeableful]

Oh that wouldn't install SDL2 and SDL2_ttf. They are separate, required packages that go-sdl2 depends on. I'm not sure if the following will work on Windows 11 but perhaps you can try it.

On Windows,

1. Install mingw-w64 from Mingw-builds. A 7z archive extractor software might be needed which can be downloaded here. In this example, we extract the content, which is mingw64, into C:\.
2. Download and install SDL2-devel-[version]-mingw.zip files from https://github.com/libsdl-org/SDL/releases.
   • Extract the SDL2 folder from the archive using a tool like 7zip
   • Inside the extracted SDL2 folder, copy the i686-w64-mingw32 and/or x86_64-w64-mingw32 into mingw64 folder e.g. C:\mingw64
3. Setup Path environment variable
   • Put mingw-w64 binaries location into system Path environment variable (e.g. C:\mingw64\bin)
4. Close and open terminal again so the new Path environment variable takes effect. Now we should be able to run go build inside the project directory.
5. Download and install SDL2 runtime libraries from https://github.com/libsdl-org/SDL/releases. Extract and copy the .dll file into the project directory. After that, the program should become runnable.
6. (Optional) You can repeat Step 2 for SDL_image, SDL_mixer, SDL_ttf
