Re: Mopac with Cygwin



The latest version of MOPAC 2002 runs under Linux and Windows. It is not free but it is fully supported by Fujitsu. For technical information see http://www.cachesoftware.com/techsupport/mopac/

 In my experience, such problems are not limited to Cygwin: I have had
 similar experience with a number of mopac's (versions 5,6,and 7) on Linux,
 IRIX, and other Unix systems.
 The only free (as in beer) version I have seen that seems to work reliably
 with "modern" Unix and Unix-like systems is from the Minnesota group:
     http://comp.chem.umn.edu/mopac
 However, this version is provided under a license agreement that doesn't
 permit redistribution.
 Let me emphasize that I am *not* a mopac expert, and I have not spent time
 trying to debug any of the codes I have tried.  I would be delighted to hear

 Linux/cygwin, particularly those that could be freely redistributed.
