Gilles,
Thanks for the clarification. I did notice the option in the configure
script. I appreciate the information on the third party C++ bindings.
The library I'm using is VTK and they happen to still rely on C++ bindings
for their parallel I/O module (unless I'm mistaken here, but this seems to
be true as of 8.1.0).
Regards,
Ajith
