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...

Re: Installing the Julia-package on macOS 10.14.5

Congratulations. Enjoy!

Thanks for the notice and for reporting the solution. As polymake has found gmp and mpfr I would suspect that the include paths and linker flags somehow get lost in the Julia package installation. We will check this.

Re: Installing the Julia-package on macOS 10.14.5

No, you don't need any of the packages that failed during the configure step. All java stuff doesn't work properly on mac os anyway. Scip ist for optimization, bliss is a replacement for nauty, singular is for computations with ideals. The output of polymake-config looks good. With my question for a...

Re: Installing the Julia-package on macOS 10.14.5

Unfortunately I cannot reproduce your problem on a fresh installation of 10.14. I would need some more details of your installation process. - Did you install brew into the standard location (which is /usr/local), or to some other path? - Does the file /usr/local/include/gmp.h exist? - Have you prov...

Re: Calling polymake from another program on a mac

polymake works the same way on Mac and Linux. The only thing that might make it look different is the binary version bundled as a Mac application. This is due to the way Apple has organized its applications. I can't change this. But apart from following apple's folder and file name requirements, the...
