compiling openmpi-1.6.5 with pgcc 15

I am trying to compile openmpi-1.6.5 with pgcc 15.1. I get the below errors :

Is there a solution to this? Thanks.

Hi Lemonade,

This is a problem with the preprocessor. To fix, set the environment variable “CPP=cpp” and then rerun configure.

Hope this helps,
Mat

Thanks, that worked. I’m curious, why doesn’t the pgi preprocessor work in this instance?

I believe it’s because cpp implicitly defines “GNU” while pgprepro does not, so these macros don’t get defined with PGI’s preprocessor.
