Can't compute VERTICES of non-pointed algebraic polyhedron

You are probably aware of this, and it is probably part of what you mean in the documentation with "limited support" for polyhedra over quadratic extensions, but I thought I should report it:
polytope > $p = new Polytope<QuadraticExtension>(EQUATIONS=>[[1,2,3]], INEQUALITIES=>[[1,0,0]]);

polytope ...

Re: Polymake 3.1: Empty polytope has dimension 1

Anyway, "just another special case". I'll work around it.

I think this is the wrong conclusion. The point is that your "AFFINE_HULL" does not fit the description of the empty polytope.

Please try the following:

> $p = new Polytope(EQUATIONS=>[[-1, 0, 0]], INEQUALITIES=>[]);
> $p->FACETS;
> $p ...

Computing VERTICES of algebraic polyhedron crashes polymake 3.1

The attached polyhedron whose H-rep uses QuadraticExtension crashes polymake (segfault) when I try to compute the vertices.
This is with Polymake 3.1 on Mac OS X, compiled within Sage using the minimal tarball. Simpler calculations, including some with QuadraticExtension, seem to work fine with this ...

Re: Polymake 3.1: Empty polytope has dimension 1

Wait! The input data is not consistent. The polytope apparently is supposed to live in 2-space. If the affine hull of the polytope is given by just on linear equation it must be 1-dimensional. The corresponding rule, which is actually triggered, is correct.

Please use "input properties" instead ...

Re: Installing polymake 3.0r1 from source on Mac OS X using gcc 4.9.2 - patch

So what's happening here is simply that GMP and other libraries are built for one architecture only, whereas "perl -MExtUtils::Embed -e ccflags" gives flags that build for two architectures at the time.
Just a quick follow-up. I have just found an easier workaround that does not require patching ...
