Hi,

I have built openmpi-1.6.2rc1 and get the following error.

Segmentation fault

Do you have any ideas or suggestions? As I wrote in my email from
yesterday, I had to add "#include <math.h>" into file
openmpi-1.6.2rc1/ompi/contrib/vt/vt/extlib/otf/tools/otfaux/otfaux.cpp
to have a prototype for function "rint" in line 834. Thank you very
much for any help in advance.

Kind regards

Siegmar
