Thanks for the answer. Indeed, I did not install the patch in the correct polymake-folder. I patched an old version on my system, so it could not work. Nevertheless applying the patch in the correct directory did not work, too. Trying to launch polymake produced the error: Welcome to polymake versio...

Thanks a lot for the workaround! Just what I was looking for.

Hello, I'm trying to compute the minimal faces of a polyhedron P, given through inequalities. The problem seems to be, that the polyhedron is not necessarily pointed. E.g. I tried computing the minimal faces as the Minkowski-sum of a bounded vertex and the lineality space. While doing so I discovere...

I am not very experienced with Linux. But the location you suggested is the exact location I tried. Applying the patch was indeed possible, but the make install-shared didn't work (that's why I thought it might have something to do with the missing make-file in the folder). Without this the patch wa...

Thanks, the patch fixed the problem for me (after I installed polymake without the .deb-package; with I had no clue where to find the make-file necessary for applying the patch).
