Hello all: I was unable to compile the latest version (1.3) on my intel 64bit system with the intel compilers (version 9.0). Configuration goes fine, but I get this error when running make: .../../ompi/include/mpi.h(203): error: identifier "ptrdiff_t" is undefined typedef OMPI_PTRDIFF_TYPE MPI_Aint; compilation aborted for dt_args.c (cod 21) My config line was: ../configure CC=icc CXX=icpc F77=ifort FC=ifort --prefix=xxx I've attached my config.log file. Has anyone encourtered this? I was able to build openmpi on this exact system using the gcc/g++ compilers, however the intel compilers are substantially faster on our system. Thanks!
