Suddenly I cannot run any mpi program. I tried running a simple mpi example that I found online and used to work on my computer.
this is the example http://mpitutorial.com/mpi-hello-world/
the error I'm getting when I type make is the following
ld: can't write output file: mpi_hello_world for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make: *** [mpi_hello_world] Error 1
This is the make file content
EXECS=mpi_hello_world
MPICC?=mpicc
all: ${EXECS}
mpi_hello_world: mpi_hello_world.c
${MPICC} -o mpi_hello_world mpi_hello_world.c
clean:
rm ${EXECS}
Does anyone know what is going wrong?
