i cannot read your mind or the mind of your computer and see exactly

arch files, errors in the installation, incompatible libraries.
JL> copy TCL libs into some directory of Cygwin manually? Thank you
why waste you time on compiling NAMD for windows anyways??
unless you have a windows cluster with myrinet or infiniband
(...and who would even want to set up such a monstrosity?),
i don't see any reason for not using the precompiled binaries.
