Re: [AMBER] AmberTools installation in Cygwin

Assuming that you have the proper X components from the cygwin install...
see line 182 of configure_at. This is where xhome is set. You can change
the value here to point to the location on your system. xhome should be set
such that libXt.a is in $xhome/lib.

These link statements won't work according to what you've said earlier in
your email. First of all, libXt doesn't exist at all, only libXt.a and do. Second of all, the directory you've given above is
/cygwin/lib, not /lib. Finally, the X-libraries are not searched for in
/usr/lib, they're searched for in /usr/X11R6/lib. I think your best bet is
to follow my suggestion above.

Good luck!
