Description of problem: If 2 (the default) or higher is selected in Print Settings|Advanced|Threads an error is reported and slicing fails. Version-Release number of selected component (if applicable): slic3r-1.0.0-0.2.RC1.fc20.x86_64 How reproducible: Every time Steps to Reproduce: 1. Attempt to slice a .stl file with default settings 2. Observe error and slicing failure Actual results: Can't locate package GLUquadricObjPtr for @OpenGL::Quad::ISA at /usr/share/perl5/vendor_perl/Slic3r.pm line 111. Expected results: Slicing should be performed without error. Additional info: Reducing the Threads value to 1 permits slicing to be performed. I have reported this upstream as Issue #1636 at https://github.com/alexrj/Slic3r
I cannot reproduce the issue. Maybe it's some package I have installed and you don't (and that is missed as a Require). I'm trying to reproduce this in virtual environment. Thanks for reporting this upstream.
Oh, are you using Quick slice from file menu? I can reproduce it then. This should fix it: https://github.com/alexrj/Slic3r/commit/5470fbbebc1d4ae5eb09196fd2c36ff3515d5b6c
Here is a scratch build of slic3r 1.0.0RC. http://koji.fedoraproject.org/koji/taskinfo?taskID=6353379 Could you please test, if it crashes for you too, when doing a quick slice with 2+ threads?
I meant slic3r 1.0.0RC2.
ABRT was invoked and reported that Perl had caught a SIGABRT. This was with 2 threads selected and reducing threads to 1 allows Quick Slice and Save As... to work correctly. This is proving to be quite a puzzle.
Thanks for testing it. In the meantime, as a workaround, I recommend you either add the STL to the plater and use Export GCODE button, or if you want to be really quick, use command line interface to slice a single STL file.
My desktop is a 3.3GHz 64-bit dual-core machine. I can live with just one thread for now.
slic3r 1.0.0RC3 http://koji.fedoraproject.org/koji/taskinfo?taskID=6603224 Still crashes. I think this might be in wxPerl somewhere :(

Slic3r 1.1.7 seems to remove thread option. Quick slice works. You can test it on F21, slic3r 1.1.7 is pending to testing.
I do not have F21 but I have Slic3r-1.1.7 installed from tarball on F20. The Threads option is still there for me under Print Settings|Advanced at the bottom of the dialog.
Created attachment 940992 [details] Fedora 21 slic3r 1.1.7 screenshot This is what I see in F21. But running from binary tarball displays that option, as you say. Weird. Maybe a missing dependency.
Nevertheless it solves the problem, right?
lib/Slic3r.pm: $have_threads = $Config{useithreads} && eval "use threads; use threads::shared; use Thread::Queue; 1"; I'll check these.
That is a pretty big clue to what is happening. Slic3r-1.1.7 from tarball *does not* exhibit this bug but we cannot exclude a packaging problem. I am no Perl expert but: && eval "use threads; use threads::shared; use Thread::Queue; 1"; looks suspicious. It obviously checks for various threading modules and the "1" is presumably for when none is detected but does it act as if something has been detected? I am wondering if that should actually be "0"?
1 will be evaluated only if all of those modules are loaded without error
Thread::Queue it is, when installed, it adds the option. And the crash is still there :(
