Hum, there are a number of good Fortran compilers for Linux out there,
check for instance the the "Linux Fortran Information page" at 
http://studbolt.physast.uga.edu/templon/fortran.html

I've been using f2c/gcc and g77 under Linux for a long time now, mainly
for our computational thermochemistry library ChemApp (see web page
mentioned in my footer). I'm running tests on Linux and a dozen other
platforms very often, and have never had any problems under Linux. g77 is
of course not the fastest compiler out there and probably won't generate
the fastest code, but it's free. There are several commercial compilers
available which for sure generate faster code, if you need that.

I have no experience with the new Digital compiler, but the old
PowerStation one wasn't exactly known to be bug-free :-)

All the best,
Stephan

  hi,

  I'm trying to get a charge analysis based on the Bader's AIM approach
  and I'm getting the following error message in GAUSSIAN94 which
  I put below together with the input card and relevant parameters

Subject: Electronic Computational Chemistry Conference (ECCC-5) Preannouncement
Content-Type: text/plain; charset=us-ascii
Content-Transfer-Encoding: 7bit


The Fifth Electronic Computational Chemistry Conference (ECCC-5) will be
held
>from November 2-30, 1998 on the internet. This will again be a web-only
event,
featuring contributed articles and posters covering any and all areas of 
computational chemistry. Discussions of these presentations will be
handled 
through a web-form mechanism. Last year, ECCC-4 attracted over 60
articles and 
well over 600 participants!

The proceedings of ECCC-5 will again be published in the Internet
Journal of 
Chemistry (www.ijc.com), a fully-featured electronic journal allowing
authors 
a seamless mechanism for presenting and publishing their ECCC5
contributions.

Complete information on ECCC5 will be available near the end of this
month.

I welcome any suggestions or comments you may have on this upcoming
event.

As always, ECCC-5 will have NO registration fees of any kind. I
encourage all 
computational chemists to particpate in this very exciting and
informative 
conference.

Steve Bachrach, on behalf of the ECCC% organizing committee

Subject: Problem with G2 restart in G94


On attempting a restart that crashed after running out of disk
space,Gaussian attempts to start the next job step (QCISD(T,E$T)/6311G(d,p))
after reading the geometry from the checkpoint file ; it then tries to read
the initial guess from the checkpoint file--at that point it prints
Logic error in ReDoC1:  IndI= 62, but NBasI= 66
Error termination via Lnk1e etc...
Does any one have any suggestions or work-arounds?
Thanks in advance,
