Re: Running out of RAM when compiling on Ubuntu

After your first session, a directory structure named ~/.polymake/wrappers.0 or similar should have appeared in your home directory. How many files with a suffix ".cpperl" are there in total? Use the `find` command to list them all, they reside in deeper subdirectories. If there are just one or two,...

Re: Running out of RAM when compiling on Ubuntu

When you install an official package via apt, there should be no need in recompilation, everything is ready to use. What exactly were you trying to do that caused the compilation?

Re: Declare and initialize Array or Vector in two steps

One word "array" has so many different meanings, it's indeed confusing and needs a more thorough documentation. I'll try to address all your recent questions at one place. There are at least five different entities that can be called "an array". The old plain C/C++ array, as in your example. It is s...

Re: how to use polymake other than command line?

You can also use the scripting facilities, as described here: https://polymake.org/doku.php/user_guide/howto/scripting . You can put your frequently used functions in separate script files, if needed, because the script command can be used in other scripts too. Just think of starting every script fi...

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

PREFIX determines where the port will be installed, by default it's set to /usr/local. On FreeBSD, DESTDIR specifies a complete alternative environment, which might be a jail or a complete system mounted somewhere other than /. The actual location a port installs to is therefore DESTDIR/PREFIX. I n...

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

Hi, since Ben has already perfectly explained almost everything, I'd just like to provide some details. installation paths Out of the box, polymake is not relocatable after the installation: It must know where to find its components (application modules, rule files, etc.) The locations are configure...

Re: Perl version doesn't match after Mac 11.3 update (Intel chip)

If you execute

Code: Select all

show_unconfigured;
in the polymake shell, it will tell you what exactly is missing. Most probably, you got this message also before the perl upgrade, because interfaces to third-party software usually do not depend on exact perl version.

Re: How to define Matrix Group from generators?

In perl, an array should be passed by reference, otherwise it's unrolled into single elements passed separately to the function. Just add a backslash: orbit(\@a,$v); Regarding the group: I'd naively expect it as a regular subobject $p->GROUP. Actually, the true group experts among us should give mor...

Re: Trouble interpreting the output (facets of a polytope)

Can I please know when should I accept the next release? This will be announced on the News page of this very website. There is no fixed release date decided yet, but it should happen in a rather short term, I reckon. Is there any other way I can transform these facets into my original variables? Y...

Re: Trouble interpreting the output (facets of a polytope)

Theoretically, you could use the opposite conversion function, 'poly2lp'. In reality, however, it won't work for you right now, because your LP is in fact a MILP, which recently became a separate data type in polymake. But we forgot to extend 'poly2lp' to cover both types of linear programs. This is...
