Re: Test failure with v4.11

I guess that is the same issue as reported in this topic.
This patch should fix it: https://polymake.org/downloads/barycentric_subdiv.patch

Re: Undefined behavior in topaz app

Thanks for the report, I have fixed this for our master branch. I am slightly surprised that this did not trigger the sanitizer build in our CI, but I will check if we can add _GLIBCXX_ASSERTIONS to one of the builds.

Re: How to define Newton polytopes of a list of polynomials and compute the vertices, rays?

I think your polynomial is not parsed as expected, it might be using the Singular-inspired short form where \(3x5\) would be turned into \(3*x^5\), and \(x11\) will end up as \(x^{11}\). So to make sure this is parsed as variables please add an underscore: polytope > $str = "(x11*x21 + x11*x22 ...

Re: mptopcom build failed

This error g++: fatal error: Killed signal terminated program cc1plus is quite often an indication that your computer ran out of memory and the operating system killed the process. Have you tried running the build process with less jobs, i.e. `ninja -C build/Opt -j1`. I would recommend at most one p...

Re: jreality doesn't start

You can set the default to jreality with prefer "jreality"; This will be stored in the polymake configuration ( ~/.polymake/settings ) and persist across sessions, until you use reset_preference to restore the default behaviour, see https://polymake.org/doku.php/user_guide/howto/shell_cust...

Re: polymake 4.7 fails to compile on FreeBSD i386

Hi,

sorry about that error, due to the limited address space, both for compilation and for actual computations, 32bit platforms are not covered by our CI.
Please try the patch I posted here on github, this will be included in the next release.

Best,
Benjamin

Re: Online shell

Hi,

sorry about that downtime. It should be working again and I will improve the monitoring that didn't catch it being down, all processes were running but one somehow stopped responding to new requests.
I will also check if I can update it to polymake 4.6 soon.

Re: Building polymake 4.6 on Ubuntu 20.04 freeze

Hi, This freezing can happen when the gcc processes exhaust all available system memory. Please try building polymake instead of the make command with: ninja -C build/Opt -j1 This will reduce the number of parallel processes to build polymake to one. You can increase the number a little depending on...
