Re: project a polytope

The choice of coordinate data type does not mess with anything, it should just reflect the nature of your input. Rational is the default choice in polymake, and this is appropriate in most standard cases. Float is also supported, but the outcome of many computations is not that reliable because of u...

Re: Calling polymake from another program on a mac

There is a subtle difference between scripts and interactive shell input. Scripts are evaluated more strictly, every variable must be declared. Interactive mode is more sloppy, it allows to introduce new variables just by assignment. You are calling polymake in script mode, hence the error message. ...

Re: Calling polymake from another program on a mac

Without seeing any error messages or code examples I can't give any concrete advice, just some general hints. There are several different ways how polymake can be integrated with other software, all of them are supposed to be generic enough to work under all UNIX-like systems, including Linux and Ma...

Re: project a polytope

I guess, all you need is to multiply the vertices of your input polytope with the transformation matrix, isn't it? Taking care of the 0-th homogeneous coordinate: $tr=(1|$f)/(zero_vector<Rational>()|transpose($E)); $Vproj=new Polytope<Rational>(POINTS => $V->VERTICES * $tr); Replace Rational with an...

Re: Installing from source on macOS 10.13

I guess, you can ignore the warnings for now. They come from some third-party package pulled in as an indirect dependency. If you get polymake built and running, then they don't matter. Regarding bundled extensions: these are just interfaces to independent software packages you have to install separ...

Re: Compiling polymake on macOS 10.14

Perpetual betas are all outdated, I think we should abandon them from GitHub altogether.

Re: Compiling polymake on macOS 10.14

Are you on the master branch of polymake, on release 3.4, or something else? I've just retried `./configure --defaults; ninja -C build/Opt` on a Mac with 10.14.4 and XCode 10.0.1, everything runs smoothly. Maybe you've "inherited" some obsolete configuration options from old releases in your build t...

Re: Segmentation Fault when using Edgemap

The data file you've posted is not the one you were using for the initial bug report, the data instance is much larger. I could not reproduce the crash on the current master branch. I loaded the graph and called the edge() function on several "tree" attachments. Since you are working with these netw...

Re: Segmentation Fault when using Edgemap

Can you please post the entire data file, so I could try to reproduce the crash?

Re: Segmentation Fault when using Edgemap

When you call the edge() method, does the $network object still exist?
If it went out of scope, the edge map is automatically lost as well.
