I've opened up a ticket at sf.net for the warnings and lack of twiddle control. Re the SEGFAULT problem, that seems likely to be related to threads and such. Usually graphics operations are not re-entrant so need to be controlled from a single thread. Sometimes that is even required to be the main thread. --Chris On Mon, Mar 31, 2014 at 9:30 AM, Schregle Roland HSLU T&A < [email protected]> wrote: > Hi Chris, > > I might add that the same code SEGFAULTs on my laptop under Perl 5.14, > even when I disable threads: > > ------------------------------------------------------------ > ----------------------------------------------------------------- > Subroutine PDL::CLONE_SKIP redefined at /usr/local/lib/perl/5.14.2/ > PDL/Parallel/threads.pm line 39. > Subroutine PDL::Graphics2D::twiddle redefined at ./GLUquadric.pl line 9. > Can't locate package GLUquadricObjPtr for @OpenGL::Quad::ISA at > ./GLUquadric.pl line 14. > Can't locate package GLUquadricObjPtr for @OpenGL::Quad::ISA at > ./GLUquadric.pl line 14. > In non-grafix thread... > Segmentation fault (core dumped) > ------------------------------------------------------------ > ----------------------------------------------------------------- > > See attachment for perl -V. > > > Best regards, > > --Roland > > > -- > Dr. Roland Schregle > Senior Research Associate > > T direct: +41 41 349 39 77 > [email protected] > > Lucerne University of Applied Sciences and Arts > School of Engineering and Architecture > CC Envelopes and Solar Energy (EASE) > Technikumstrasse 21, CH-6048 Horw > T +41 41 349 33 11, F +41 41 349 39 60 > www.hslu.ch/ccease >
