MPICC set as an environment variable outside of octave, so "putenv MPICC mpicxx" does not change anything. Did you actually look at the error log? I have open-mpi 3.0.0 and octave 90bd5649983c.

Best,

Seb, 

yes from the log it seems the linker cannot resolve symbols from the mpi library. If the linker is invoked via mpicxx this should in principle not happen.

Can you try uncompressing the package and running make from within the src directory? If you look at the makefile there are a few more variable s you can try to change.
