Nix build - SDLCallFailed

Closed this issue · 7 comments

prolic commented

I can successfully build the monomer project using nix build. However the resulting binaries have some problems:

./result/bin/todo 
Invalid window
todo: SDLCallFailed {sdlExceptionCaller = "SDL.Video.glCreateContext", sdlFunction = "SDL_GL_CreateContext", sdlExceptionError = "Invalid window"}

Hi @prolic!

I don't know much about Nix, so I'm probably not the best person to help here (although it's high on my list of things to learn). Looking at a comment made by @smunix (the contributor of the Nix and GitHub Actions configuration), it seems you should run the applications with a different command:

nix run .#todo

I remember running them successfully in an Ubuntu VM.

Doesn't seem to work either. Feel free to close this issue if you want to. I'm just struggling myself for over a week to setup nix for my project.

I think you may need nixGL (I remember having to use it). It was mentioned in this PR.

Just to be sure: have you checked nixGL? The error you're getting can probably be fixed by using it.

I'll close this issue for now. Please re-open if needed. Thanks!

I was seeing this error on a different monomer project on NixOS. I don't know if I had the same root cause as the original poster but when I ran the app under nixGL instead, the problem went away and the app works.

I can confirm that nixGL fixes the problem. However I decided to move forward without nix builds. Thanks.
