Error when generating support material

[pbilluart]

Version of Slic3r : 1.3.0

In order to check that I get the same .gcode, the same filament length and the same time of slicing with slic3r as I got with PrusaSlicer, I tried to slice in CLI with Slic3r a .stl file using my default configuration from PrusaSlicer (save in config.ini) by typing :

./slic3r -g ProtoGnome.stl --output ProtoGnome.gcode --load config.ini --info

and I got the output here below, with a lot of errors as you can see. The config.ini file was set at first in a such a way to generate supports (this file is attached and the .stl file as well). Next I modified the config.ini file in order to cancel the generation of support (support_material = 0 in config.ini file) and the error lines "Layer processing ERR: Layer...." just disappeared, suggesting the problem comes from supports. Beside the needed filament length remains the same as with and without supports, suggesting that it's not generating support at all when the errors occur. Do you know how to fix it ?

Furthermore, in the case of "no support" demanded, the filament length outputted by slic3r is quite different from the one outputted by PrusaSlicer (set with no support too) whereas both are running on the same .stl and the same config. Is it
normal ? I thought Slic3r was the engine of PrusaSlicer.

PS: I had to change the extension of config.ini file and ProtoGnome.STL to be able to attach them, their extension is .txt :
ProtoGnome.txt config.txt

Output from Slic3r when enforcing the generation of supports :

Got the same problem running latest master version (b1a5500 ). Building slicer on Linux from source code.
Have you been able to solve this problem?

[Stepkur]

I was building slic3r using cmake and got this problem. Then I tried to build slic3r on a newer Linux using perl- the problem has disappeared. So I'm guessing right now latest master versions don't fully support building by cmake. Not sure, but something similar is described in guide how to build on Windows
