[FLASH-USERS] How to install FLASH4.6

Hi Zhang!

>*./flash4: error while loading shared libraries: libmpi.so.20: cannot open
shared object file: No such file or directory*
>*./flash4: error while loading shared libraries: libmpi.so.20: cannot open

I had this same problem. At least in my case, the problem was that FLASH
looked for the library *libmpi.so.20 *that didn't exist because mpich
provides another similar but with another name, e.g. *libmpi.so.40.20.1 * .
The problem was overcome easily creating a symbolic link to give FLASH what
it wants to,

  $ ln -s *libmpi.so.40.20.1 **libmpi.so.20 *

Best!
