Topic: Lake: linking SDL2 woes
Siddharth Bhat (Mar 23 2023 at 15:41):
I'm building SDL + OpenGL bindings for Lean4. In doing so, I'm trying to debug a lake build failure, but it seems like lake build --verbose prints unrelated info?

Hi, I think most likely you're missing "alsa-tools". You can run apt list alsa-tools to check if it's installed.
Siddharth Bhat (Mar 23 2023 at 18:25):
I am more concerned about the fact that lake build and lake build --verbose fail in different ways. It is unclear to me what is failing, since the command cmake --build run from the directory SDL/build actually succeeds
Anders Christiansen Sørby (Mar 23 2023 at 19:03):
I have made a library binding for SDL2 already if you are interested https://github.com/Anderssorby/SDL.lean

I don't think they're failing in different ways. The cmake presumably succeeds without --verbose as well, Lake just doesn't print it.

Perfect, thakns!
