oops, I guess I forgot to check in some changes for Cygwin-i686.
I will fix them later today. However, please compile NAMD
with Win32-i686-MSVC and with net-win32 of Charm++ (using VC++ instead of
gcc) since I found some tricky things with Cygwin/gcc - one seems to have
to use -fpack-struct gcc compile option to pack structures in order to
generate same structure alignment as Linux gcc.
I have fully tested Win32-i686-MSVC with VC++ and checked in all the
changes for it already several days ago, so it should compile and work out
of cvs server without any change.

I had same problem with Cygwin/GCC3.2. GCC 3.3 links fine with some fixes
in NAMD for compile errors.

I normally don't bother to compile NAMD with tcl and plugins. I only
worry about fftw for my benchmark testing purpose.
I don't have precompiled library for tcl and plugins for cygwin/gcc,
and I don't know how to make them. So I guess I can only compile the VC++
version of NAMD for you (the precompiled tcl, plugins libs are available
online at namd website i think).

Actually I was launching NAMD from the second computer in the nodelist
under cygwin. The cygwin path is "/home/work/", however, as you can
see I still need to map it to the corresponding Win path of
"C:\cygwin\home\work\" even it is on the same machine.
Also remember to deal with firewall if you have it enabled on Linux or

No. It can be implemented but not for windows I guess.
