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...

Re: Building polymake 4.6 on Ubuntu 20.04, linking problems with flint

Have you tried manually removing the (manual) flint installation from /usr/local ? I.e. deleting /usr/local/lib/libflint* and /usr/local/include/flint . That should make sure that the package manager installation is used and at least give a different error message when building polymake. For the man...

Re: Visualization bug(?) in Polymake 4.6

Some of the new changes to improve the transparency don't play well with intersecting faces. I have an idea what we might change but I need to check various cases for side-effects ... For now, please try pasting the following in the javascript console of you browser after opening the visualization: ...

Re: Perl MongoDB module at EOL

Hello,

we do have plans about that but unfortunately none of that is implemented yet. We will probably switch to the MongoDB C++ driver.
In addition to that we might try to add a very basic interface that doesn't need any extra libraries but interfaces directly with our Rest API.

Best

Re: SageMath installation problems

Dear Simon, I can only tell you as much as that this error message is not from the polymake build-system. Since the polymake team is not involved in the SageMath interface we cannot help you any further, so please try asking in the SageMath forum or have a look at these question with a similar error...

Re: Testsuite regression with nauty on FreeBSD

Unfortunately there is a small mistake in the patch, in the case that --without-prereq is passed to configure the -lnauty flag for the linker will be missing. Please try this patch: https://polymake.org/downloads/libnauty2.patch

Re: Mixed volume -> edge matrix is singular?

Hi, unfortunately you hit a bug in our mixed volume implementation. This bug is already fixed in the most recent polymake release 4.4, but is still present in the 4.2 release that was active in the webpolymake until today. I have now updated webpolymake to version 4.4 which does work for your exampl...

Re: polymake on FreeBSD -- some questions and help needed

I have another question concerning the shared library: Right now, the port provides libpolymake.so.4.4 and libpolymake-apps-rt.so.4.4. What about libpolymake-apps.so.4.4? Should that one be provided, too? If so, I have to figure out why that one is not picked up by pkg. Sorry for the delay. That li...

Re: polymake on FreeBSD -- some questions and help needed

I don't really know how you ended up with these undefined symbol errors for libnormaliz but they should disappear when adding ' -lnauty ' in the correct place, either in the global ' LIBS ' variable passed to configure ( ./configure LIBS=-lnauty ) or by adding an appropriate check in the libnormaliz...
