Thanks. Now I'm getting the following error message fan > $Sigma = fan::secondary_fan($P->VERTICES); polymake: used package gfan Gfan is a software package for computing Groebner fans and tropical varieties.

I see. Then how do I get the 1-dimensional cones ? Or the maximal cones ? I seem to get an empty result which I know not to be true.

Thanks a lot for the quick reply. Now, I have the next problem: $ptmat = new Matrix<Integer>([[1,0,0,0,0],[1,2,-1,-1,-1],[1,-1,2,-1,-1],[1,-1,-1,-1,-1],[1,0,0,1,0],[1,0,0,0,1]]); $P = new Polytope<Rational>(POINTS=>$ptmat); $Sigma = fan::secondary_fan($P->VERTICES); polymake: transforming /private/v...

Hi! I have the same problem here. I use polymake 2.12 and gfan 0.5 in Mac OS X 10.6. The subroutine secondary_fan is undefined and I get the error message polytope > reconfigure "gfan.rules"; polymake: ERROR: there are no configuration actions associated with rulefile gfan.rules Do you hav...

Thanks a lot. This worked. I completely forgot that I had the 32 bit version of fink installed. I will install the 64 bit version in the near future.

Again, thanks a lot for your quick help.

Thanks for your quick response. The file /System/Library/Perl/5.10.0/darwin-thread-multi-2level/auto/Encode/Encode.bundle exists. I had /sw/lib/perl5/ExtUtils:/sw/bin:/sw/sbin: in my path variable. After removing them and calling polymake I get essentially the same message $ echo $PATH /usr/bin:/bin...

Hi everybody, I downloaded the bundle for Mac OS X 10.6 and had it run on a MacBook Pro 6,2. I get the following error message: /Applications/polymake.app/Contents/MacOS/polymake.start ; exit; Can't load '/sw/lib/perl5/5.10.0/darwin-thread-multi-2level/auto/Encode/Encode.bundle' for module Encode: d...
