Re: Release candidate for Qhull 2012.1

[Tatsuro MATSUOKA]

Hello

I have built Qhull 2012.1 on MinGW and built octave with it.
However, fntests results
  src\DLD-FUNCTIONS\convhulln.cc .........................panic: Segmentation 
violation -- stopping myself...

So I execute ./run-octave

octave:1> cube = [0 0 0;1 0 0;1 1 0;0 1 0;0 0 1;1 0 1;1 1 1;0 1 1];
octave:2> [h, v] = convhulln (cube);
panic: Segmentation violation -- stopping myself...

I have attached Ben's patch ( qhull.diff )
http://octave.1599824.n4.nabble.com/Compiling-with-Qhull-tp4205738p4293994.html

The below exe files created in bin directory produced in the make process.
qconvex.exe, qdelaunay.exe, qhalf.exe, qhull.exe, qvoronoi.exe and rbox.exe 

Can I execute some test using these files ?

Regards

Tatsuro
