Building with LLVM Suddenly Stopped Working

AspiringGameDev

Suddenly, I can no longer build a working Godot with LLVM. The build itself succeeds without errors, but the application itself simply opens the Project List window, changes the title, (if there are no projects to list, it will bring up the dialog to ask if I want to open the asset library), and then quits. No content is drawn in the window (or dialog), everything is black.

Here is the command line I use to build: scons -j12 platform=x11 target=release_debug use_llvm=yes use_lld=yes

I'm building with LLVM 10. It doesn't make any difference whether or not I use lld as the linker, the result is the same. So for now I'm stuck using gcc for building godot.

Is anybody else having this problem to? Do you have any solutions or workarounds to keep using LLVM?

Building master? 4.0 is still in active development so not surprising if something got broken and gets fixed again in a matter of time.

Doesn't matter whether it's master. I get the same problem even building from the same snapshot that I used to be able to get a working build from.

For that reason, I don't think the problem is in the Godot code, but in something that has changed on my end. The thing is, all I've done is install system updates as they became available. I'm hoping someone else might be in the same boat, or might even know what's going on.

I suppose it's remotely possible that there's some fragility in the code that's been exposed, but I think the best course of action is to troubleshoot everything possible outside of Godot's code first before even suggesting it's a bug (or temporary master-branch issue) in Godot.

Something to do with your config then? Might be easier to do a clean building setup then, probably.

Try cleaning all build products with git clean -fxd. Beware: this removes all untracked and ignored files. Don't run this command if you have unsaved work in the Godot repository folder.

Hmmm... Would I need to do that even if I start from a fresh extract from the zip archive of the snapshot from github? Because that's what I've been doing.

I have a crash log with a backtrace.

For anyone else who had run into this problem, it was fixed by the Godot devs a couple of days ago.
