Compiling OSSIM with MPI support

MPI Dependencies

OpenMPI

$ sudo apt-get install mpi-default-dev

Setup

Same as previous examples, except:$ ./configure --with-mpi=1 --with-openmpi-flag=1

On razor, libraries are in non-standard locations, so:

./configure \--with-openthreads=/home/sbobovyc/OpenThreads \

--with-mpi=1 --with-openmpi-flag=1 \

--with-mpi-lib=/share/apps/mpi/openmpi-1.5.1/gcc-4.1.2/lib \

--with-mpi-inc=/share/apps/mpi/openmpi-1.5.1/gcc-4.1.2/includ
