Looks like ifort on your system is generating 32-bit .o files by default. configure:20653: gcc -O3 -DNDEBUG -fno-strict-aliasing -I. -c conftest.c configure:20660: $? = 0 configure:20670: ifort conftestf.f conftest.o -o conftest ld: warning: i386:x86-64 architecture of input file `conftest.o' is incompatible with i386 output Rainer wrote: > >PS: When compiling OpenMPI are You using a combination of gcc for C/C++ > >and ifort for Fortan compilation? > >This will not work, as the compilers have different views on e.g. boolean > >variables and values, so parameter passing from Your code into OpenMPI > >will be botched up.

We (and Intel) both do bool like g++ does, but we each do LOGICAL to match the history of our Fortran compilers. I never imagined anyone would think these should be the same. -- greg
