I just tried out slic3r on a recent 16.09. Same problem here.

[timor]

After some digging it looks like the glWindowsPos4* symbols are missing from libGL.so, but I am not sure they are supposed to be there in the first place. However, they are required by the perl OpenGL bindings.

[timor]

Updating perlPackages.OpenGL to 0.70 did the trick on my machine.

[bjornfor]

Hm, I get segfault (after upgrading OpenGL to 0.70):

$ ./result/bin/slic3r --gui
Segmentation fault

[timor]

I based my modifications on this commit: 45b2a6d

I have the branch here if you want to try: https://github.com/timor/nixpkgs/tree/slic3r-gui

Also, it seems it is not working perfectly: The print surface is not rendered. This may be a problem with the graphics drivers though. As far as I can tell, I am using the free ATI drivers (haven't changed anything in configuration.nix).

[bjornfor]

@timor: Hm, your opengl bump is exactly like mine, so there must be something else.

[pjones]

I cherry picked the commit from @bjornfor and can report the same results. Slic3r works, but it doesn't render the print surface anymore.

Can we get someone from upstream involved?

[pjones]

@bjornfor Do you need any help with this issue? I'm still having to patch nixpkgs due to this. Thanks.

[globin]

Pushed that commit to master and 17.03 as it definitely improves the situation

[pjones]

@globin That patch at least lets slic3r run, but it's missing the object platform. That makes it very hard to use. Do we need another issue to track that?
