The big news in this release is support for the 32-bit x86 architecture and ports to several more operating systems. CCL now runs on:

  • Mac OS X 10.4 and later (PowerPC and x86)
  • Linux (PowerPC and x86)
  • FreeBSD 6.x and later (x86)
  • Solaris (x86)
  • MS Windows (x86)

There are 32- and 64-bit versions for all platforms.


Barton Willis reports, “As of last evening, the Maxima test suite runs OK using 32 bit Clozure for Windows XP. I thank the Clozure CL developers, Gary Byers and R. Matthew Emerson, for their help. Being able to run Maxima using Clozure CL under Windows, Linux, and OSX will be a great for the Maxima community.”
