 IRAF on new laptops

Does anyone know if the MAC version of IRAF would work on the new MAC intel-based MacBook ? Alternatively would the LINUX IRAF version be more compatible?

A new port is required for a number of reasons, and I can guarantee that neither the existing mac/linux systems will simply recompile on the new platforms. We're very keen on doing the port but need access to a machine first (both for the initial port and long-term support/patches). This would also be a good time to do things like move to G77 for compilation, consolidate the linux versions, etc. See the Projects and Support pages for more about our hopes/plans.-Mike

A somewhat more detailed follow-up question:The new Intel-based Macs (iMac and MacBook Pro) can also run (most) PowerPC-based MacOS X programs using the Rosetta emulator, which translates PowerPC code to Intel code. This is slower than using native Intel code, obviously, but it provides a potential interim solution while waiting for code to be ported to the Intel architecture.Your answer implies that generating an Intel-native set of iraf binaries for Intel-basesd MacOS X (the ideal ultimate solution) is not trivial, but do you have any idea whether the current MacOS X (PowerPC) iraf might run in the Rosetta emulator on Intel Macs?

A port is not trivial, but it isn't that difficult either. In any case, I haven't actually seen a physical machine yet so can't answer about Rosetta until I try it. If anybody else ordered a machine and can try it, please post here.Assuming though that it does run, the things most likely to NOT work are compilation and signal handling. Also keep in mind the byte-swap issue betwee PPC and Intel -- binaries may run but think the image data is swapped. Anyway, will let you all know what we find out.-Mike

Mmm, yes I'm sure it'll take some doing to get IRAF running on Intel based OS X, what with the byte swapping and such. On a slightly related matter, the IRAF Button Applescript Studio program I wrote is now a Universal Binary. With the new xcode 2.2.1 tools and a few changes to the project it compiled Universally fine. Of course, Applescript-based applications are basically a tiny cocoa-shell with some applescript inside, so making it Universal is trivial and also probably not needed... still, it worked. Since no one is running IRAF yet on Intel based Macs, I haven't put it up on my web site yet.
