VMD-L Mailing List

Hi guys,
  The long standing issue with 64-bit builds of VMD on windows has
to do with the libraries that are needed. I would do the compilation
with the MS compilers rather than minGW or cygwin as they historically
had issues with OpenGL, but you can certainly give it a try if that's
what you have to work with. The major issue has always been getting
a correctly functioning Tcl/TK+FLTK, once that is sorted, the rest
is mostly easy. The other issues on 64-bit Windows will be that
the drivers for the Spacenavigator that we have been using aren't
supported for 64-bit mode, and similar issues for other (optional)
libraries. The only things you _must_ have working to get VMD up
and running on Windows are Tcl/TK and FLTK, the rest could be dealt
with later. I'm out of town at the GPU Tech. conference until next
week, but I am happy to work with you guys on this when I return.
In particular, I would suggest trying Tcl/Tk 8.6.0 and see if you
can get that build on 64-bit Windows and we can go from there.

Cheers,
  John Stone
