I will also point out that we write a *lot* of MPI programs and never use mpiCC. It is usually better to just determine what they are doing and replicate it. mpiCC usually just adds an include path at compile time and a library or two at link time. We have run on almost every MPI implementation on the planet including some very exotic big machines and this has always worked.

Could you tell us what the errors are?

We need to determine if this is a Manta CMake thing or just a CMake thing. If it is a CMake thing, then you should ask this question to the CMake mailing list cmake@cmake.org.


It could be a CMake thing but I'm unsure. I'm using cmake-i to set the build
option. Even though I've already set CXX=mpiCC and CC=mpicc it still lists the
default values (see below). It also refuses to accept my manual override at the
command prompt and continually re-prompts for a value:

Variable Name: CMAKE_CXX_COMPILER
Description: CXX compiler.
Current Value: /usr/bin/c++
New Value (Enter to keep current value):

Variable Name: CMAKE_C_COMPILER
Description: C compiler.
Current Value: /usr/bin/gcc
New Value (Enter to keep current value):
