General summary/comments (optional)

If i try to build a project with sdl2 dependency, stack complains about pkg-config.

stack build
sdl2     > configure
sdl2     > Configuring sdl2-2.5.3.0...

I can workaround it with stack exec -- env PKG_CONFIG_PATH="C:\Users\rtentser\AppData\Local\Programs\stack\x86_64-windows\msys2-20200903\mingw64\lib\pkgconfig" stack build (it brings other issues, but not related, i guess).

The problem is with pkg-config: it doesn't see sdl2 package.

Steps to reproduce

1. stack exec -- pacman -S mingw-w64-x86_64-SDL2
2. stack exec -- pkg-config --libs --cflags sdl2.

Expected

pkg-config should find sdl2.

Actual

stack exec -- pkg-config --libs --cflags sdl2
Package sdl2 was not found in the pkg-config search path.
Perhaps you should add the directory containing `sdl2.pc'
to the PKG_CONFIG_PATH environment variable
Package 'sdl2', required by 'virtual:world', not found

Stack version

Hi there!
Did you solve your problem?

[rtentser]

No, not really.
But didn't try it for a while, so maybe something changed, i need to retest it.

[New-York00]

Could you try?

Trying to build something using sdl2 on Windows 10, I get, after a lot of other things the error message below, and the workaround above doesn't work for me because there's nothing in my mingw64\lib folder. I can't find a pkg-config on stackage, and by the looks of it, that's a posix thing I don't have on Windows 10.

I followed the instructions here on reddit which got sdl2 installed, but then my project was stuck on SDL2_ttf, so I tried stack exec -- pacman -S mingw-w64-x86_64-SDL2_ttf with some success, because it compiled, but needed SDL2.dll and SDL2_ttf.dll. The first is available at https://www.libsdl.org/download-2.0.php and the second at https://www.libsdl.org/projects/SDL_ttf/

This is weird because I remember half a year ago trying to find solution to the same issue as described here (didn't find this post then). I remember just downloading SDL2.dll or following reddit post metioned by @Andrew-Clow.

I am closing this issue given the passage of time and because I recently built something on Windows with a dependency on SDL2 without difficulty: see haskell-game/dear-imgui.hs#198.
