Hi all,

I am trying to use the mesh local differential properties on a mesh (on a windows 7 / 64 bit), and I have a few questions.

1) When I execute the sample program (with the default parameters), I get (a lot of) errors on the console: "MKL ERROR: Parameter 12 was incorrect on entry to DGELSS"

Since you're also using linux, is it working fine on linux? This is a pb with Lapack/Blas libs, I have no clue what's going on on windows.

2) The file xxx.4ogl.txt is created. How can I view it?

Sorry the README is not up to date, the file 4ogl.txt was used by a no longer existing demo program. 

Use instead the option -vtrue to get a human readable result, then you may want to modify the output to visualize it with your favorite tool

(Now what is becoming the recommended visu tool for cgal is

   QGLViewer. I've never used it but it is qt and opengl based so

   standart and you can find demo code, for polyhedron for instance

You can get more information here http://www.libqglviewer.com/index.html)

   Hope this help

   best

Hope you could help.

Best regards,

Asher
