Graham,
you can configure Open MPI with '--enable-script-wrapper-compilers' that will make wrappers as scripts instead of binaries. Cheers, Gilles On 3/3/2017 10:23 AM, Graham Holland wrote:
Hello, I am using OpenMPI version 1.10.2 on an arm development board and have successfully cross-compiled the OpenMPI libraries and am able to use them with simple MPI applications. My question is, what is the best approach for cross-compiling more complex MPI applications which use mpicc to determine compiler flags? The mpicc that is built is an ARM executable and obviously cannot be run on my host. An example of such an application is MPPTEST, which uses mpicc from within its Makefile: ftp://ftp.mcs.anl.gov/pub/mpi/tools/perftest.tar.gz I have read in the FAQ about overriding the compiler wrapper default flags using environment variables, so one possibility is to use my host mpicc with these set appropriately. I am wondering however if there is better way?
