Looks like a misconfiguration of your X11 installation, e.g. OpenGL library not compatible with the graphic card drivers. If you are not experiencing any troubles with other graphical programs on your computer: maybe your Java comes with an own broken OpenGL library? At any rate it does not look lik...

Sometimes the jreality window hides itself behind others. But you have surely already checked this. Please start polymake with increased debug output level: polymake -dd and re-enter your commands. You will see plenty of irrelevant stuff about rules and so on, but eventually, following the credit no...

Then the chances are good that this bug is indeed fixed. The next release is scheduled for coming February, AFAIK. If you are not going to wait that long, please upgrade to the snapshot. If it's absolutely not feasible for you, you should find the places in your code where it tries to store a ListMa...

The major problem is not linalg.h itself but a bug in polymake which has sometimes led to a wrong compiler command. The release is already 1 year old, and I hope the bug has been fixed in the meanwhile. Anyway, you haven't replied to my last questions in PS. They may be relevant if the bug is observ...

polymake sometimes wants to generate and compile missing glue code for data exchange between C++ and perl worlds. To see more clearly what's going on, please increase the verbosity level before you call your function: $Verbose::cpp=2; If the error happens already at start-up, you can place this sett...

Code: Select all

polytope> $p = new Polytope(load("path/to/your/file"));

$p=load("..."); suffices.

Polytope<Rational> is the default object type for application polytope.

Thank you for the confirmation. Is there a perl IDE like MS Visual Studio for C++? You can follow into the functions, see the value of variables. Maybe there is one, but I'm not aware of. For `old-fashioned' command line debugging the built-in perl debugger is good enough. See here for basic hints,...

It's definitely not possible for convex hull computations, as both main engines (cdd and lrslib) do not print any progress information. Most probably, the lattice point enumeration will also be quiescent. You can try running polymake in debug mode: `polymake -d'. You will see a lot of unrelated nois...

There are too many brackets for my taste. Let's make it simpler: my @labels=@{$p->COORDINATE_LABELS}; shift @labels; # get rid of the wrong leading one $s=new Polytope(POINTS=>$p->LATTICE_POINTS, COORDINATE_LABELS=>\@labels); Please remove 'my' in the first command if you enter this snippet in the i...

... how you name your variables does not matter. Polymake should still parse the lp-file. I'm afraid, it seems to be not completely true. When you look into the LPparser perl class, you'll see a "prefix" option there defaulting to "x". It suggests that all variables in fact shou...
