Re: Bundle-installing polymake on Mac OS X 10.8.5

The bundle for 10.9 can definitely not be deployed on your machine. The problem with the bundle for 10.8 roots at your Fink installation (/sw/lib). Although your system is apparently newer than the original one where the bundle had been built, the libxml2 library contained in your Fink seems older. ...

Re: Performance issues with Latte

One second extra time looks like a usual overhead for resolving a rule chain, sorting out preferences, etc. Between the property query and the actual call to the third-party software (latte) in background there are a lot of other activities. Especially the rule scheduling is notoriously slow. Usuall...

Re: Mac 10.9, close but problem with perl

You are missing the fink package ''term-readline-gnu-pm5100'' or similar (in particular, the number might have changed).
Should be -pm5162 now, according to the posted log.

Re: Mac 10.9, close but problem with perl

dyld: Symbol not found: _Perl_mod Referenced from: /usr/local/lib/polymake/perlx/5.16.2/darwin-thread-multi-2level/auto/Polymake/Ext/Ext.bundle Expected in: flat namespace That's strange. Perl_mod in fact disappeared since perl version 5.16.0, but polymake knows this and takes appropriate precautio...

Re: Computing the dual of a polytope

A small side remark: you don't need to `prime' the variable p1Pol with an empty Polytope, when you are anyway going to overwrite it in the next line. polymake is based on perl, and like many other scripting languages, its variables are dynamically typed.

Re: polymake config not finding jni headers

Oh, thanks, this is a good advice anyway. I'm afraid, this script has been tested so far only on systems where the java binary location was deduced from environment variables like JAVA_HOME or JDK_HOME. I'll improve the script as to cover your case.

Re: polymake config not finding jni headers

The java-related part of autoconfiguration tries to deduce the location of jni.h from the path of the java binary. There are, however, too many different variants of subdirectories, symbolic links, etc. in the world. Probably your one is not yet reflected in the modest knowledge of the script. If yo...

Re: handling the adjacency matrix of a graph in C++

You may indeed store the graph adjacency matrix in an IncidenceMatrix, but you must retrieve it correctly. The appropriate type to receive the "ADJACENCY" property is the C++ class Graph. Graph<> gr = p->give("GRAPH.ADJACENCY"); IncidenceMatrix<> adj = adjacency_matrix(gr); As a ...

Re: Polymake with Perl 5.18.0

Does this problem only arise when trying to establish a guest access?

I've upgraded svn to 1.8 on my home PC quite a while ago, and haven't experienced any troubles so far.

Maybe it's the empty password what svn doesn't like anymore? Let's try setting it to "guest"?
