[mpich-discuss] undefined reference to `__isoc99_sscanf'

[Alison Boeckmann]

Andy,

You spotted the problem. I was using a  version of the library that was
built on  a
different Linux system.
 I replaced libmpich.a in my working directory with  the file libmpich.a
 that was built on the Ubuntu box that I
am working on, and it now runs ok.

Thank you *very* much for your help.
