I am trying to configure Open MPI using CMake 2.8.8 and Visual Studio 2005 in 32 bit mode, with Intel Fortran. The machine is a 64 bit machine running Windows XP 64 bit, and VS has 64 bit support.
Configure works fine without f77 bindings, but as soon as I add this option, I get the error: Checking for working Fortran compiler...

Please check Fortran compiler installation, or disable Fortran 77 support. Call Stack (most recent call first): contrib/platform/win32/CMakeModules/ompi_configure.cmake:616 (INCLUDE) CMakeLists.txt:99 (BEGIN_CONFIGURE) Configuring incomplete, errors occurred! I am using all default options, except that I have specified a cmake_build_type of release. Both the c and cxx compilers appear to be pointing to the 64 bit versions, but changing these to the 32 bit versions does not seem to matter. If I attempt to compile testFortranCompiler from a command prompt it compiles without any difficulties (ifort testFortranCompiler.f, with no other flags). Any ideas which options I am missing to get this to work?
