Re: Ubuntu 14.04: crashing while configuring

Hello, please correct me if I am wrong. But from the screenshots I suspect that you "double clicked" the configure file in your filebrowser (because I do not see any shell prompt). If that is the case the terminal did not "crash", it just closed itself after running the script. What you might want t...

Re: what is inhomog_var ?

When I look at the code, I suspect that if you look at the order property 'COORDINATE_LABELS' you will see that the facets are also shifted by one.

Re: what is inhomog_var ?

Hi there, we talked about it and found some inconsistencies in our code. In the meantime, you might want to do the following as a workaround: $s=new Polytope(POINTS=>$p->LATTICE_POINTS, COORDINATE_LABELS=>[splice([@{$p->COORDINATE_LABELS}],1)]); problem is that print_constraints thinks that the firs...

Re: Please share C++ sample code

Hey, I do not know if I understood you right. But how you name your variables does not matter. Polymake should still parse the lp-file. And the names of your variables will be stored in the property COORDINATE_LABELS . Regards Benjamin EDIT: but anyway you should only use proper lp-code. You might w...

Re: LATTICE_POINTS & callable library

User methods and property retrieval look so innocently equal in the interactive shell, it doesn't come as a surprise that people are tempted to call both in the same way in C++ code. Maybe give() should gracefully fall back to method call when the property lookup fails.

Re: Polymake doesn't start after compilation

can you give us a little bit more information like: linux distribution c/c++ compiler perl version could you paste your environment variables related to perl (e.g. PERL5LIB, ...) maybe you could strace polymake with: "strace -o logfile.txt /path/to/polymake" and upload the logfile.txt here thanks

Re: Compute the intersection of two fans

Hm, if I may highjack this thread: if I want to create a fan consisting solely out of the lineality space, what would be the prefered way? a) a fan consisting of a lineality space and the empty cone as maximal cone b) a fan consisting of a lineality space and the origin as maximal cone Simon chose ...
