Dear Dr. Case,
Thank you for your comments. It has taken me awhile, but I've now gone
back and reconstructed pieces from the problems with my installation of
Amber9. Mistake 1): I originally had defined the AMBERHOME environment
variable in the Cygwin.bat file as a DOS command (with the apparent
misunderstanding that Cygwin would translate it to the POSIX format
as it does for the PATH variable). Upon running the configure command,
however, and finding a mixed path in config.h, I recognized the problem
and moved the AMBERHOME definition to the Cygwin environment. So, now I
needed to edit the mixed DOS/POSIX path in config.h. Mistake 2): Being
new to Linux/UNIX, new to Cygwin and new to Amber, I used Windows Word
Pad as a text editor. BUT, not all text editors are equal, despite
identical-looking output files. As you, no doubt, already know, line
terminations in Windows/DOS consist of both a carriage return (\r) and a
newline (\n), whereas Linux/UNIX uses only a newline (\n) for this
purpose. Both bash and Bourne shells have a problem with \r, but there
seemed to be no problem changing to ash, so I did. Thus, I'm now
planning to re-install Amber9 (a bit older and a bit wiser) -- I'll have
a chance to check on the behavior of patch with bugfix.all at that time.
Recommendations to other newbies trying to install Amber9 in a Cygwin
environment like me: a.) be sure to define the AMBERHOME environment
variable *within* the Cygwin environment, and b.) use *only*
Linux/UNIX-friendly text word processors like, for example, vi or emacs.
Finally,
I would reiterate Dr. Case's final point: *first* try things as stated
in the instructions (if you aren't part of the solution, you're probably
part of the problem)!

Thanks for the detailed instructions. I have a few comments, based on
my
Cygwin experience.

I don't think this should be necessary. I routinely use the bugfix.all
file, without change, on cygwin. So, try the instructions as written
first.

You should not have such mixed formats. This looks like you somehow set
up the
AMBERHOME variable with backslashes, even though your email indicates
that you
did not do that. You really don't want things like "C:\" in your
variables,
and this never happens to me.

I have never had the need to do this. For me the test suite works
without any
changes.

It should be very helpful. My advice is to first try things as in the
instructions, and if they fail, look at some of the fixes Bob lists
here.
...thanks...dac
