Re: Problem in compiling Polymake in Arch Linux

Thanks for the report, this comes from a conflict of the -std options from your singular installation and from polymake. Please try applying the attached patch in your polymake source directory and run configure again afterwards. cd /home/laisrast/Downloads/polymake-3.2/ patch -p1 < /path/to/singula...

Re: sh: ninja: command not found

Hello Ngoc,

please install the package 'ninja' manually.

The Arch Linux package for polymake seems to list ninja only as a build-dependency but not as a runtime-dependency. polymake needs ninja to recompile autogenerated wrappers which happens during the startup of polymake.

Best,
Benjamin

Re: Running into error with 3.2 installation

Since ppl 1.2 is not available as a package for Ubuntu 16.04 you need to download and install it manually, it is available here . Something like the following should work for the installation, please check the INSTALL and README.configure files in the ppl package for more information. ./configure --...

Re: Running into error with 3.2 installation

Just a short information regarding ppl:
Ubuntu 16.04 provides ppl version 1.1 while polymake 3.2 needs version at least 1.2.
So it does make sense that polymake 3.0 can work with the installed ppl but polymake 3.2 cannot.

Re: Reading CPLEX Integer Program and generating facets via script

Hello, the load_commands function was made mostly for software demonstrations, you should use the script function for your task, see [1] for more details. Then you can also call it directly from the command line and easily redirect the output (tee duplicates the output to the terminal and a file): p...

Re: Mac OSX 1-key brings up help

I just hit the same issue on opensuse 42.2 and this might be caused by a broken termcap/terminfo database shipped with ncurses (broken in version 20170701, fixed in 20170715). $ perl -e 'use Data::Dumper; use Term::Cap; $Data::Dumper::Useqq = 1; print Dumper(Term::Cap::Tgetent->{_k1});' $VAR1 = "\eO...

Re: compilation problem

Please try the workaround in the attached patch (which is originally from the fedora polymake maintainers). Our testsuite just completed without any further errors (with gcc 7.1.0).

Re: Face lattices of polytopes

The tutorial is now updated. There is also a shortcut to get the nodes of a given dimension (in contrast to the rank): print $p->HASSE_DIAGRAM->nodes_of_dim(1); Or printing the faces (and this should work with both 3.0 and 3.1): print map { $p->HASSE_DIAGRAM->FACES->[$_] } @{$p->HASSE_DIAGRAM->nodes...

Re: Installation problems CentOS 6.8

A few comments on the required versions: polymake 3.0 should build with all gcc versions starting from 4.2 (but might have issues with very new ones), the minimal perl version is 5.10.0 (see https://polymake.org/doku.php/howto/install_legacy ), both should be satisfied in CentOS 6. The compilation e...
