@nh2 Any suggestion what I could try next? |

There is, but because the builds can take tens of hours (timing out the usual VM-based CI systems), it's using Buildkite and HerculesCI with a community-sponsored dedicated bulider machine, which aren't safe for building untrusted code, thus they don't build all PRs automatically. I haven't figured out yet how to tell Buildkite via its UI or a Github comment to build contributer PRs after looking at them, so I build them manually so far. Some tips regarding this would be appreciated! |

I have succeeded building SDL2 and associated libraries statically now, and also But what needs research is how to make a static SDL2 find a graphics card or use software rendering via Mesa /nix/store/wydhcgwplw9grms8d3y8sdfm5srg8xgb-LambdaHack-0.10.2.0/bin/LambdaHack

What happens when you do I was able to reproduce the problems with a small C++ program and I was told libgl can't be linked statically, see utdemir/ghc-musl#14 (comment) No idea how to link a software rendering replacement of libgl (llvmpipe?), but that may be the only solution, unless we can make dlopen to work. |

@Mikolaj On Ubuntu I get: SDL_VIDEODRIVER=x11 ./LambdaHack

@Mikolaj Sorry, that error was misleading: That happened when I tried to run the game on a headless machine without any graphical display, which doesn't make sense. The newer error from above is the one to look into. |

Collecting here some links where people build static GUI apps with Mesa |

I've also posted the question to the SDL forum here: https://discourse.libsdl.org/t/what-are-my-options-for-static-linking-on-linux-with-software-opengl-support/32549 |
I'm getting (on my Ubuntu 16.04 desktop, no VM) But that's already more than I was getting with ghc-musl, because a windows opens up and only then it fails with the message on the console. |
|
For what I gather this won't be possible in alpine due musl, since it doesn't support dlopen() calls. That is for my case at least, not in haskell/ghc. https://github.com/libsdl-org/SDL/blob/main/src/video/x11/SDL_x11dyn.c#L164 |
