[MPICH] about C++ and SEEK_SET

[Zaiwen Wen]

Thank you for your message.

Jim kindly told me to add CPPFLAGS="-DMPICH_IGNORE_CXX_SEEK" during 
configuration and finally, I solved the problem. Anyway, thanks for your 
replying.

Regards!
Zaiwen

Zaiwen,

Please try adding

CPPFLAGS="-DMPICH_IGNORE_CXX_SEEK"

to the list of options to pass to configure.
