Dear Ross,

I can't locate libimf.so on my system ! I have downloaded both ifort and
mkl from intel website and installed them. But there seems to be no file
called 'libimf.so' in the lib directory where the intel compiler is
installed.

However, adding ' source /opt/intel/fce/9.0/bin/ifortvars.sh ' to .bashrc
worked :) I then started running 'make test' which seemed to be working
until it gave the following error:

cd qmmm/divcon; ./Run.crambin
forrtl: severe (174): SIGSEGV, segmentation fault occurred

sander.QMMM 0804A3E5 Unknown Unknown Unknown
libc.so.6 B7C7C34E Unknown Unknown Unknown
sander.QMMM 0804A321 Unknown Unknown Unknown
  ./Run.crambin: Program error
make: *** [test.sander.QMMM] Error 1

I also tried the static installation but there also I encountered some
problem. I am attching the config.h file and the error message.

adding it or make sure that you source the Intel setup script in your
.bashrc or .cshrc as specified in the ifort manual. E.g.:

incompatibility between the operating system and the intel compilers. I
would contact Intel support about the issue.
