I'm trying to use mpicxx with cygwin. I've installed all openmpi packages available but when typing mpicxx still get a "command not found". I looked into the /usr/bin folder and mpicxx is missing, while C and fortran versions are there. Any possible explanation or solution?

mpic++ and mpicxx are just links to opal_wrapper.exe you can reinstate by yourself
It is the same for all the other compilers
$ cd /bin
$ ls -l mpi*
