I downloaded NWChem 6.8 and could successfully compile it with MPI support. Now, for some tests I would also like to have a purely serial version of NWChem. However, when I set
export USE_MPI="n"
it gives the following error message:
mpif90 not found. Please add its location to PATH
I wouldn't expect that mpif90 is needed for a serial version of NWChem. I also tried around with a range of other settings, such as not defining USE_MPI at all, etc. However, none of these approaches worked.
Could somebody give me a hint what I'm doing wrong here?
