[LLVMdev] OpenMPI and llvm-gcc

[Frank Fuchs]

Hi,

I was wondering whether or not MPI-libraries are expected to work with  
llvm-gcc?

I tried to compile openmpi-1.3 using the llvm-gcc4.2-2.5-x86-darwin9  
distribution on my MacBook Pro running OS 10.5.6.
Installation using the gcc (gcc version 4.0.1 (Apple Inc. build 5490))  
worked well.

But for the llvm-gcc I get the following error message (during the  
make):
