Hi Anton

It seems Gert's patch was included in 1.20.0-9, but with my name on it.

1.20.0-9 FTBFS on the Ubuntu buildds with the following error:

In file included from
/«PKGBUILDDIR»/lib/triangulation/FlowBoundingSphere.hpp:170:0,
                 from
/«PKGBUILDDIR»/debian/build/pkg/pfv/FlowEngine_FlowEngineT.hpp:39,
                 from /«PKGBUILDDIR»/pkg/dem/TriaxialStressController.cpp:22:

there are no arguments to ‘isinf’ that depend on a template parameter,
so a declaration of ‘isinf’ must be available [-fpermissive]
        if ( isinf(m) && j<10 ) cout << "(cell->info().kNorm())[j2] =
" << (cell->info().kNorm())[j2] << " cell->neighbor(j2)->info().p() =
" << cell->neighbor(j2)->info().p() << endl;
                    ^

Reverting to the patch I uploaded with 1.20.0-8ubuntu1, and the same
as I attached to this bug, fixed the build.

Graham
