Re: Installation problems CentOS 6.8

A few comments on the required versions: polymake 3.0 should build with all gcc versions starting from 4.2 (but might have issues with very new ones), the minimal perl version is 5.10.0 (see https://polymake.org/doku.php/howto/install_legacy ), both should be satisfied in CentOS 6. The compilation e...

Re: Can the H_STAR_VECTOR be computed for rational polytopes?

Hello, First, sorry for the delay. As far as I know, the notion of h^* -vectors for non-integral polytopes is not really well established as there is no canonical choice for the denominator of the Hilbert series. In hindsight we probably should have restricted this property to lattice polytopes. In ...

Re: Installing polymake 3.0r1 from source on Mac OS X using gcc 4.9.2 - patch

We have published release 3.0r2 now. The minimal tarball now includes the nauty interface (without the nauty sources) along with a small configuration script which allows specifying a nauty source directory via the configure command (--with-nauty-src). Just for clarification: The "rather specia...

Re: show_unconfigured shows error "Unrecognized character \x7F"

We have released 3.0r2 now and included a warning when having neither bliss or nauty active. Further, the minimal tarball now includes the nauty interface which allows using a custom nauty source directory, polymake will then build a static library out of it. (The interface currently does not suppor...

Re: Installing polymake 3.0r1 from source on Mac OS X using gcc 4.9.2 - patch

To install polymake 3.0r1 from source on Mac OS X using gcc 4.9.2 (this is within Sage), I had to apply a patch to get rid of all "-arch" flags; see https://github.com/mkoeppe/polymake/tree/sage-package This is to fix errors that can be seen on https://trac.sagemath.org/ticket/20892#comme...

Re: Bug in REGULAR property of a polyhedral fan

Hi, thank you very much for the report. There was indeed a bug in our regularity client which we have now fixed in our development branch and the fix will also be included in 3.0r2 (which is scheduled for the next week). Best, Benjamin PS: For anyone trying to reproduce this, the fourth unit vector ...

Re: perl extension issue on Fedora

Thank you for the hint. This is a perl core module but as it seems to be separated in some distributions we have added a comment about this on the installation page.

Re: show_unconfigured shows error "Unrecognized character \x7F"

This error seems to be caused by having no graph-comparison tool available, which is a somewhat unsupported configuration. The bliss extension failed to configure and the minimal package doesnt contain nauty as fallback because of its license. This package is meant for maintainers that make sure the...

Re: Installing polymake on Ubuntu 14.04

Hi,

you need administrative privileges to install polymake, hence you need to run:

Code: Select all

sudo make install
I will clarify the corresponding wiki page.

Best,

Re: Tropical and ERROR: Can't use string ...while "strict refs" in use

Hello, please consider upgrading your polymake version. The line in question was written for a very old polymake version 2.9.4 and with version 2.13 should work as follows: print rows_labeled($p->PSEUDOVERTICES); A more up to date reference for similar computations is our tutorial on application tro...
