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

I assume that your previous version of polymake was not installed with 'brew install polymake' but either completely self compiled or using brew just for the dependencies, and then polymake was installed into the standard location with 'ninja -C build/Opt install'? In that case you probably have a v...

Re: Error in reading a .lp file using lp2poly

Your file is utf-8 encoded, while polymake expects a file that only contains the standard ascii characters. As long as you stick to letters/digits/spaces this is not a problem. But utf-8 has several versions of a space character, and your file contains some of the "nonstandard" spaces. You...

Re: installing polymake 4.3 on Mac OS X 11.1, Big Sur

SVG is indeed missing in the latest bottle, and I also remember now that I had a reason to remove the module some time ago (it did not compile properly). However, SVG is not a necessary prerequesite for polymake, so it should work without. I assume you still have an old local polymake configuration ...

Re: installing polymake 4.3 on Mac OS X 11.1, Big Sur

This looks like a polymake installed via Homebrew? So you issued brew install polymake at most two days ago (I only updated the formula on tuesday to hopefully also work for Big Sur, seems it still does not). By design of homebrew all perl modules used by polymake are bundled together with the polym...

Re: Polymake bundle on MacOS 10.14.6 working (probably also 10.14.5)

Cool. Many thanks for trying! This is really helpful.
I have already put a note on our download page pointing 10.14 users to the 10.15 bundle.

If you have any further questions please post them.

Happy polymaking!

Re: Downgrading perl in MacOs

Unfortunately we will probably not be able to provide binaries for 10.14.5 soon, as I don't have access to a Mac or a virtual machine with this version of MacOS. I will try to provide binaries for 10.15 (Catalina) sometime in January for the (then) current release of polymake. Switching the perl ver...

Re: Finding the cone-facet correspondence in the normal fan

If computed with the function normal_fan from application fan, the rays of the normal fan come in the same order as the facets of the polytope, and the facet-vertex incidence matrix (FACETS_THRU_VERTICES) of the polytope has the same row and column order as the ray-maximal-cone incidence matrix MAXI...

Re: Content of Cone::RAYS if there are no extreme rays

I am not sure I understand what you intend to do. Without own programming polymake does not do any incremental generation of extreme rays or generators (some convex hull codes used by polymakemay do this internally, but we don't provide access to this). You however get the following guarantee: If yo...

Re: Content of Cone::RAYS if there are no extreme rays

polymake splits the information about the generating set of a cone C into two parts: For any cone we can find a pointed cone D and a linear space L such that C is the Minkowski sum of those two (Minkowski-Weyl-Theorem). The cone D has a unique (up to scaling of the individual generators by a positiv...

Re: Installing the Julia-package on macOS 10.14.5

One more thing: polymake sometimes compiles new code at runtime and rebuilds some libraries (whenever you, or a package you use, uses a C++-template instance of a polymake class that did not occur before). So you should set the variables each time you use polymake in julia, or wrap the julia call in...
