Re: Perl version doesn't match on new installation for macOS Big Sur 11.6.2 (Intel processor)

Indeed, this bundle is broken. I am sorry. I was preparing bundles for the new version of polymake anyway, so I thought I provide this instead, but this currently does not work for Mac OS 11 (Big Sur). I have to investigate the reason and will publish the bundle once I found and fixed the problem. T...

Re: Mac OS Monterey

I am not aware of any problems. There are, however, currently no binaries, neither for homebrew, nor as bundle. We don't have a Mac or virtual machine with Monterey.
Did you try to compile the sources? If this didn't succeed you can post the error message here and we will try to help.

Best

Re: Finding integer vertices in an MILP

I am not sure what you mean by "extreme point". Can you please give a definition? There are eight integral points contained in the polytope, which you can compute via print $p->LATTICE_POINTS; 1 0 0 1 0 1 1 1 0 1 1 1 1 2 0 1 2 1 1 3 0 1 4 0 Six of them are on the boundary: print $p->BOUNDA...

Re: Finding integer vertices in an MILP

Yor can compute the integer hull of a polyhedron with the function integer_hull and then ask for the vertices: $q=integer_hull($p); print $q->VERTICES; 1 0 0 1 0 1 1 2 1 1 4 0 Note however, that this internally computes a representation of all integer points in the polyhedron. There is no significan...

Re: Perl version doesn't match after Mac 11.3 update (Intel chip)

Many thanks for pointing out the change in the perl version. This always comes unexpected... I have uploaded a new bundle for 11.3, and with the brand new polymake version 4.4.

Re: macOS Installation Problems

The missing EXTERN.h should hopefully be found after

Code: Select all

export CPATH=/Library/Developer/CommandLineTools/SDKs/MacOSX10.15.sdk/System/Library/Perl/5.18/darwin-thread-multi-2level/CORE/
before installing with

Re: macOS Installation Problems

On 10.15 and later it is not anymore necessary to force link the readline library. I have updated the installation instructions. But the installation of Term::ReadLine::Gnu should have worked regardless. Can you retry to install it with cpanm Term::ReadLine::Gnu and if it fails post the error message?

Re: Can't locate loadable object for module Polymake::Ext in @INC

Yes, sorry, remains of the previous installation of polymake were not the only problem. I was able to reproduce this on my VM. The perl bottle of brew has been updated from 5.32.0 to 5.32.1 since I compiled the bottles. As polymake uses perl XS, which is compiled code and depends on the precise vers...
