I can see your point. At the moment, there is no effort at all to support any operating system that does not Sun or GNU compilers. i.e. nobody is making any effort at all to support HP-UX, AIX, tru64 etc.

A shame! I certainly make sure that all of these are supported by my own software. Other than gaining access to a system, it is not particularly difficult for well designed software.

I agree. I've had one of my own programs on a large range of platforms. To quote from the web page:

"In addition to the the commmon Linux PC, atlc has been tested on a Sony Playstation 2 as well as the Cray YMP-EL supercomputer, which is available for free public access at Cray-Cyber network. It has also been tested on Debian Linux, Slackware Linux, Gentoo Linux, Redhat Linux, Suse Linux, IBM's AIX, Apples's OS X for Mac, HP's HP-UX (both PA-RISC and Itanium), SGI's IRIX, Sun's Solaris, SCO's UNIXWare, HP's Tru64, Cray's UNICOS, NetBSD, OpenBSD and FreeBSD."

However, unless there is someone with access to an HP-UX box, and is interested in helping develop Sage on HP-UX, it is just not going to happen. I have machines at home capable of running Solaris (both SPARC and x86), tru64, AIX, HP-UX and IRIX. But I've no inclination to use any of the other operating systems - for one the machines are too old.

The problem is, if we started from scratch, I'm sure with an eye to portability, we could have made Sage very portable. But making use of existing software means you are reliant on what others have done before you. Given there is probably a hundred plus man-years gone into the development of the software Sage uses, it's not practical to rewrite everything from scratch.

I'd love to see a port to HP-UX, where I know at least one person is interested in Mathematical software, but the userbase is not large. Wolfram Research gave up development on AIX and IRIX many years ago, and HP-UX more recently.
