Runtime LLVM error

[vinayakvijay]

I am getting the following error upon running the demo-app (on ubuntu 24.04LTS using compiler gcc-13.2.0):

: CommandLine Error: Option 'disable-auto-upgrade-debug-info' registered more than once!
LLVM ERROR: inconsistency in registered CommandLine options
Aborted (core dumped)

What could be the fix of this issue?
Note - i am accessing some of the dependencies through a spack package environment

Hmm, I don't know anything about this. Googling the issues seems to suspect it's related to low-level LLVM stuff and linking configurations.

Polyscope uses a pretty boring setup and links against standard packages.... any chance this is an issue with the platform rather than something Polyscope-specific?

Did you observe this on the current master branch? There were a few changes merged recently to additionally link with EGL when it is available, I suppose it's possible one of the EGL dependencies is a source of new problems.

Maybe could try setting cmake -DPOLYSCOPE_BACKEND_OPENGL3_EGL=OFF .. at CMake configuration-time to see if the error goes away? (Don't forget to delete the CMakeCache.txt when you rebuild.) Or you could build from the old tagged v2.3.0 version.

Indeed it looks like the issue is caused when working with the spack environment. It works fine with the standard installation of packages.

Tried this but doesn't work still.

Thanks for following up!

Ok, seems to be a general problem, unrelated to those recent EGL changes. Has probably been this way for a while.

Hmmm, that's annoying. Unfortunately I don't have a way to help with this, and it's hard to say for sure if it's a problem with Polyscope's build setup or just a general issue with spack packages.

If anyone can suggest a change to Polyscope's build options that would resolve this I'm willing to merge it, but otherwise I don't think I can help here.
