The callable library, libpolymake.so, has two undefined symbols: xmlGetExternalEntityLoader xmlSetExternalEntityLoader I see that support/corelib.make builds Ext.so with LIBXML2_LIBS, but does not use those libraries when building the CallableLib target, which includes all of the *.o files in Ext.s...

Dear Jerry, we have been confronted with the same requests from the Debian community, so that we are currently working on separating some of the external bundled libraries from the core distribution. We expect to have this done by the end of April and then we'll produce a new release. We are definit...

Yes, a clear stupid bug. Thanks a lot for watching out!

polymake can be used with any perl starting with 5.8.1, but the following should be observed: Using the system's own perl is the preferred way to work with polymake. perl packages provided by Fink may or may not work, they are too numerous to be conscientiously supported by our team The architecture...

Nothing simpler than that: you just log in under http://www.polymake.org/trac/polymake and click on "New Ticket".

I'll look into it.

Generally, you'd better post such bug reports directly as Trac tickets. The Trac system shares the user credentials with the SVN repository.

It must be a Mac-specific problem, this function works under Linux smoothly, so that I unfortunately can't help you directly. To get more insight, please try running polymake with -d switch. You'll see a lot of internal communication garbage, but hopefully some relevant diagnostics will also pop up....

There is also a more compact form of this query: print $M->(1,2); It has the same performance as the expression above, but saves some typing and also works as lvalue , that is, if the matrix $M is not write-protected, you can assign to it any boolean expression: $M->(1,2) = 0; $M->(2,1) = $a &&a...

This bug has already been reported elsewhere in the forum and is also already fixed in the development branch. Do you have an access to it, or do you want to get it?
