Hi Marcos, We do not plan to provide a Solaris version of Chimera. I suspect that there would be slightly fewer Solaris users than there are SGI users, and Chimera downloads for SGI make up only 3% of all downloads. The other 97% are for Windows, Mac and Linux. Unfortunately it is a great deal of work to build Chimera. It requires 25 third party packages (TclTk Togl Tix Pmw PyOpenGL zlib Python Numeric jpeg tiff freetype Imaging netcdf Scientific MMTK HappyDoc tr openssl ftgl omni msms otf autostereo swish-e FFmpeg). One of them (msms for molecular surfaces) is proprietary code that we cannot give out. It would probably take a few days for a programmer to build all these packages and the Chimera code on Solaris. If inspite of all that you want to try, let me know, and I will ask if I can give you the source code. The Chimera C++ source is currently not available for download. Tom
