Re: [sage-support] Re: SAGE and .NET interoperability.
OK, this patch appears to fix the problem, indeed. Dima 2010/1/11 Stephen Linton s...@cs.st-andrews.ac.uk: Try this patch for saveload.c: 708a709 static Obj ProtectFname; 727a729,731 /* For some reason itanium GC seems unable to spot fname */ ProtectFname = fname; 730a735,736 ProtectFname = (Obj)0L; 1070a1077,1078 InitGlobalBag(ProtectFname, Protected Filename for SaveWorkspace); It should bullet-proof the filename through the garbage collection.

Regarding Itanium and Sage, here's the specific statement from our README.txt about Sage's official platform support: OFFICIALLY SUPPORTED PLATFORMS -- Building of Sage from source is regularly tested on (minimal installs of) the following platforms: PROCESSOROPERATING SYSTEM x86 32-bit Linux -- Debian, Ubuntu, CentOS (=Red Hat), Fedora, openSUSE, Mandriva x86_64 64-bit Linux -- Debian, Ubuntu, CentOS (=Red Hat), Fedora, openSUSE, Mandriva IA-64 Itanium 2 64-bit Linux -- Red Hat, SUSE x86 Apple Mac OS X 10.5.x PPC Apple Mac OS X 10.5.x In particular, we support running Sage on Itanium 2 with 64-bit RHEL or SUSE. In order to upgrade the GAP spkg in Sage, we just need an spkg that can be dropped into the Sage install (i.e., sage -i gap-.spkg) such that the Sage test suite passes: make test ... All tests pass! Last time with gap-4.4.12 (I think), the spkg worked on everything but Itanium, where there were serious issues (mainly involving saving workspaces, I think, which our test suite caught). We couldn't sort out the issues when making that particular Sage release, so we just reverted to gap-4.4.10, hoping that things would get fixed by the next Sage release. (I did write to Steve Linton about the issues, but I don't think I did a good job following up...) But then we got lazy, and here we are. But you're clearly not lazy, so I really hope this gets sorted out. Note that GAP didn't support Itanium at all 2 years ago. I got access to some Itanium machines, and then convinced Steve Linton to write new assembly code so that the memory manager for GAP would work on Itanium. He graciously did so, for which I'm very thankful. If you need access to the Itaniums I use for build testing, let me know (off list) and that can be arranged. -- William -- To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-support URL: http://www.sagemath.org

IMHO, it might be more reasonable to require Cygwin with the right tools (gcc + cython + whatever else is needed) being pre-installed, than to package everything in one mega-bundle. (one could perhaps have a custom Cygwin installer, with right things selected, provided) Possibly one can do all three, then find out what people demand by far the most: * self contained install (includes cygwin1.dll, etc.) * tar ball that gets extracted into an installed cygwin (like what we distribute for linux) * a standard cygwin package that one installs via the cygwin setup.exe program; e.g., singular is in there already. Although I understand that I touch upon a sensitive issue of packaging Sage in general... :) We just want to minimize our work and the complexity of the problem. By the way, anything new about moving to the newest GAP version? Somebody should post a new spkg. Then I'll test it on Itanium and see whether or not it works. If not, then it doesn't go in, but we can at least report the problem again to the GAP list.

There is little chance that these parts would be ported to Windows natively (on the other hand, e.g., GAP has a Cygwin port, that is well-supported etc). I toyed with making a native port of GAP to Windows some ten years ago. It was a highly non-trivial task that would have taken me months back then (and then I was relatively well-versed in Windows programming). So a native port of Sage would still settle for Cygwin ports of some of its modules. That was why thought such a port would take 10-30 man years. William and I disagree over what is a 'native' application, but as he said, the lawyers can argue that one out. It helps that Sage's primary front end is a web interface, in a native Windows browser--as long as the back end runs smoothly and out of sight the user won't notice how it works. As for those that preferrer the command line, they'd probably be just as happy in a Cygwin shell or VM (if they choose Windows at all). I'm more hopeful about the Sage Python classes--Python and Cython are both supported on Windows, and distutils is supposed to handle all the linking stuff. I'm not saying there won't be issues though--from what I've seen of it the path to a Windows port is littered with so many tools and solutions that, in theory, should Just Work (cygwin, colinux, virtualization, ...) but in practice just don't. - Robert -- To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-support URL: http://www.sagemath.org
