the log tells that linking with the MPI libs did not work. Configure tried the linker flag -lmpi and -lmpich (not relevant for openmpi). For more details have a look into config.log and search for the failed linker job. config.log has tried both. What flags do you use on your machine to compile and link a simple test MPI program?

Configure seems to work when I do this. ./configure .... LDFLAGS="-L/usr/lib/openmpi" ./configure ... LDFLAGS="$(mpicc -showme:link)" Is it possible to automate this? — You are receiving this because you commented.
