problems getting prusaslicer installed on Fedora 30
Please tell me if this is not the right place for newbie questions. I want to get PrusaSlicer running on my home laptop which is a lower end Dell running Fedora. I downdoaded the AppImage from the prusa site (AppImage tech is new to me) and ran a chmod +x on it. Invoking it gives me:
error while loading shared libraries: libGLU.so.1: cannot open shared object file: No such file or directory
cd /
sudo find . -name libGLU.so.1
./usr/lib/libGLU.so.1
echo $PATH
/home/<userid>/.local/bin:/home/<userid>/bin:/usr/share/Modules/bin:/usr/local/bin:/usr/local/sbin:/usr/bin:/usr/sbin:/usr/lib/
so it should be findable. Owned by root, perms 755. So it should be usable.
Googling tells me that it indicates that the app is an OpenGL user. I'm a retired Java/web dev guy, and I'm down a rabbit hole here. Ideas?
Thanks in advance - Dan Fox

OpenGL is the graphics driver requirement. Older Intel CPU's with graphics built in do not support newer OpenGL standards. So you need to enable the OpenGL software emulation, which is invoked via command line. I've tested it under Windows, but I don't have the cl arguments for Linux... you'll need to find them somewhere.
The Windows cl looks like this:
prusa-slicer-console.exe --sw-renderer --loglevel=5

Thanks! Likely not the issue, as this laptop was purchased new less than 4 months ago. Nevertheless I will pursue this when I get home Monday. Just wanted to acknowledge your reply.

Digging into it, I find that I have the "8th generation Intel Core I5" with "UHD Graphics 620" integrated on the processor chipset itself. Intel claims that it supports OpenGL "thru 4.5". I'm guessing that I'll have a hell of a time finding out what level of OpenGL support is required for this, but it's not the first suspect in this detective story.

So, it's fixed. I can't put my finger on the exact problem, but what I did is as follows, roughly:
Google "test OpenGL install on Fedora30 Linux" and various related phrases. End up at: https://linuxconfig.org/benchmark-your-graphics-card-on-linux
Install Phoronix Test Suite (appears to be a handy little toolset!). IIt says to check "how OpenGL works with your hardware accelerator" to install Steam and try running a game written with Steam.
Steam is a quarter gig install. Also it wanted to update a LOT of existing dependencies. (I suspect this is where the healing took place.)
Steam games worked. Go try PrusaSlicer and it worked.
Hope this helps - Dan
