Hello, in the meantime, perl-data-uuid had already been added to Guix. I have reimported perl-net-bonjour and perl-growl-gntp and pushed them. Then I have adapted your perl-alien-wxwidgets to modern conventions and pushed it. perl-wx as attached fails with the following message, so I did not test perl-wx-glcanvas: No such 'link' library: 'adv' at /tmp/guix-build-perl-wx-0.9932.drv-0/Wx-0.9932/build/Wx/build/MakeMaker.pm line 212. It looks as if the wxwidgets are not found, which makes me wonder if the perl-alien-wxwidgets package is correct... Is there still interest in slic3r? Wikipedia claims that prusa-slicer (which we have) is an improved fork, but maybe it work only with Prusa printers? If there is no interest, I am going to close the bug. Andreas
