Thanks for the reply. I installed the 5124 and it worked fine. I installed gcc47 from Fink (had to update my Xcode for taking care of a dependency). But I am not sure how to use it. I tried doing ./configure CC=/sw/bin/gcc-4 but doing the make after it gives the same problem. I did not add the CXX ...

I am on MAC OS X 10.8.2, trying to install the latest polymake. I have this when I do ./configure WARNING: perl module Term::ReadLine::Gnu required for polymake not found on your machine. I can see Gnu.pm under /sw/lib/perl5/5.12.3/darwin-thread-multi-2level/Term/ReadLine/Gnu.pm My PERL5LIB env var...

(1) Is there a better way to detect integrality, or non-integrality of a polyhedron than just computing all its vertices and looking at them? Without any assumptions on the inequalities defining your polyhedron computing the vertices is the only option. There are faster ways if the defining inequal...

I was about to write... I checked today with a fink installation on Mac OS 10.8. The package seems to be okay, and on the computer I checked also PERL5LIB has been set correctly by fink. It should point to "/sw/lib/perl5".

Anyway, if it works now then ejoy polymake.

This seems to be a bug in fink, the file should be at Term/Readline/Gnu.pm. Currently, the fink package database is unavailable, but I will check as soon as I can access the package.

Indeed, this function does not yet exist in the released version of polymake. But it only scales a matrix with the common denominator of the entries (without the first column, which is the homogenization). As long as you ensure integral input the gfan-function should work without it. I'm not too fam...

I am sorry, modifying the PATH variable was not a very useful recommandation. The problem is the list of locations perl checks for its modules. Please check the variable $PERL5LIB and remove any path starting with /sw (in the same way as you modified $PATH). Most likely you can just make it empty wi...

I am a bit puzzled with this error. Mac OS should have its own version of the perl::Encode module, so it should not try to load the fink one. Could you please check whether the file /System/Library/Perl/5.10.0/darwin-thread-multi-2level/auto/Encode/Encode.bundle exists? Does /sw/lib/ appear in your ...

in polymake, the graph of a polytope is encoded as a sub-object of type Graph (like the one you can create with "new Graph(...)" in application graph), so the edges are listed with $p->GRAPH->EDGES; Similarly, you can get the adjacency matrix via $p->GRAPH->ADJACENCY; and the neighbors of ...

The bug has been fixed in fink, but observe this before issuing fink selfupdate.
