PrusaSlicer installs with warning, then won't launch on RasPi 500

[mckillip]

Confirmations

• I searched for similar bug reports in https://github.com/Botspot/pi-apps/issues and found none were relevant.
• I tried updating Pi-Apps and the issue is still not fixed. How to update Pi-Apps?
• IMPORTANT: I promise to respond to comments on this issue and write a good bug report https://www.softwaretestinghelp.com/how-to-write-good-bug-report/

What happened?

PrusaSlicer installation generates a warning in a console (that quickly closes!) and won't run when launched

Description

Similar bug report was closed, with remedy to install a missing library. Following doing that, PrusaSlicer still did not run. Warning during install pointed to an OpenGL issue, but I am not knowledgeable enough to freeze that console window to copy the full text.

Thanks for looking into this! - B.

Does the same issue occur on pi os 64-bit?

[mckillip]

Hello, thanks for the response. Yes, the RasPi500 is running 64 bit. When PrusaSlicer is launched from the console I get: MESA_GL_VERSION_OVERRIDE=3.3 /opt/PrusaSlicer.AppImage /tmp/.mount_PrusaSVm1BKP//usr/bin/prusa-slicer: symbol lookup error: /lib/arm-linux-gnueabihf/libwebkit2gtk-4.0.so.37: undefined symbol: g_power_profile_monitor_dup_default I did find comments online about how to revert back to an earlier version of PrusaSlicer. If this is too much trouble to tweak these dependencies, I can go ahead and do that. Thanks for your work!

Hello, thanks for the response.

Yes, the RasPi500 is running 64 bit.

Pi-Apps reports your OS is 32-bit. In your first post, you pasted your system specs:

OS: Raspbian GNU/Linux 12 (bookworm)
OS architecture: 32-bit

Where do you see that it is 64-bit?

[mckillip]

My bad! I was looking at the Kernel, using uname -m versus the OS via dpkg-architecture --query DEB_HOST_ARCH which shows it to be 32 bit after all. I should have done better web searching on that.

Hello! I can't recall if I included this in an earlier reply, but this is the result when running Prusa Slicer from the command line: MESA_GL_VERSION_OVERRIDE=3.3 /opt/PrusaSlicer.AppImage /tmp/.mount_PrusaSLxtWOt//usr/bin/prusa-slicer: symbol lookup error: /lib/arm-linux-gnueabihf/libwebkit2gtk-4.0.so.37: undefined symbol: g_power_profile_monitor_dup_default Thanks, yet again - hope this is informative.

I can't recall if I included this in an earlier reply, but this is the
result when running Prusa Slicer from the command line:

MESA_GL_VERSION_OVERRIDE=3.3 /opt/PrusaSlicer.AppImage
/tmp/.mount_PrusaSLxtWOt//usr/bin/prusa-slicer: symbol lookup error:
/lib/arm-linux-gnueabihf/libwebkit2gtk-4.0.so.37: undefined symbol:
g_power_profile_monitor_dup_default

Is that from a 64-bit OS, or still 32-bit?

[Botspot]

@mckillip I have the same question. Did you switch to a 64-bit OS, or are you still using 32-bit raspberry pi os bookworm?
