I should have added the problem I got was with 3.0.2, with twisted. I think you have perhaps made some changes to that, so I'm in the process of downloading sage-3.0.3.alpha1.tar. Unfortunately, I'm only getting 50 KB/s, it will be another 15 minutes before I have the tarball. > But the medium term plan is to switch to the Sun Forte compiler and I > have no intention to ever even put substantial time to make the 64 bit > port work with gcc.

Essentially the Sun compilers are faster than gcc, so changing for that reason alone would be useful on code which is going to be CPU intensive. I can't see Sun trying to charge for their compilers again. I think they would **** off too many people, including many of their own employees. But who knows, they have made some odd decisions before with how they changed the license conditions on Solaris. * At one time Solaris was commerical only * Then it became free for up to 8 CPUs. It did not inforce the 8-CPU limit, but few people have machines with more than 8 CPUs. * Then they called Solaris free, but in only if the machine was capable of holding just one cpu, and furthermore the machine was bought from a Sun authorised resller. This mean it was not free for 99% of users. In practice, since anyone could download it, you can guess what people did. * At one point they used to charge a nominal fee to download the x86, but not SPARC version. I think they got fed up with a lot of downloads, with people not bothering to install it. I can see some logic in that. * Then Solaris became free and open source. So who knows? Depending on what way the wind is blowing, Sun will send you a Solaris Express DVD and them pick up the postage, or you pay for the postage. Their policy seems to change from week to week, with no real logic to it. Going back to Sage, I imagine the switch from gcc->Sun compilers is going to present quite a few challenges, as the options are so different. I believe there is a gcc interface to the Sun compilers so it can be called with gcc options, but I think it is better to use the right Forte options. BTW, are there any other ports planned, like HP-UX? I have a HP-UX box here, but it has not been switched on for many years. I also have tru64 on a Dec Alpha, IRIX on an SGI Octane and AIX on a large IBM server, but none of the machines have been on for years. About time I got rid of them I guess! But I know from my efforts on ATLC http://atlc.sourceforge.net/ that building software on multiple platforms tends to find a lot of bugs, which don't show up on platform A, but the bugs are there, ready to surface at some later date. ATLC has been built on many platforms including a Sony Playstation and a Cray supercomputer. --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-devel@googlegroups.com To unsubscribe from this group, send email to [EMAIL PROTECTED] For more options, visit this group at http://groups.google.com/group/sage-devel URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
