I encounter an error from PALP when I try to create a dual cone. I create a cone Cstar as an intersection of several other cones, then try to create its dual:
How do I increase POLY_Dmax?
The latest Sage development version does not use PALP for cones any more, partly because it suffers from compile-time limits. Now it uses PPL and has no limits (besides ram and cpu time) for all practical purposes. And is faster, too :-) You need Sage-4.7.1-alpha1 or higher.
For the record, though, if you really want to use PALP for higher-dimensional problems then you must edit its Global.h header. PALP has no bounds checking, so make sure to increase the maximal number of points to suit your problem, too. Just increasing POLY_Dmax is likely to end up in segfaults.
