I was trying to install a parallel version of CHARMM on another machine. I usually do it with:

./install.com gnu M

I get this printed on the screen:

install.com> Processing CHARMM source on gnu...

Using mpif90 for compile
ar: `u' modifier ignored since `D' is the default (see `U')

The binary is there and it runs, but I get each line printed 16 times for each node I am using in the output file.

How can I fix this issue?

Thank you
