The latest version of guile, guile-1.8, does not work on ia64. See #401400 for more information.
Because lilypond depends on guile, this causes a problem for further support for lilypond on ia64 in Debian. The latest version of lilypond, 2.8, does not build against guile-1.6.8, and thus requires guile-1.8. Bug #401498 is my request to ftpmaster to remove the ia64 package for lilypond since the current source cannot support this arch until guile-1.8 works. According to #401400, Rob Browning (Debian guile maintainer) has forwarded relevant info to the upstream developers' list, but there isn't any short-term progress likely yet there. I'm not the guile maintainer, so I can't offer any more information except what I read on the lists, and this: guile is based on the scm interpreter, and ia64 did not ever work successfully on scm until the upstream scm maintainer (Aubrey Jaffer) was asked by me to look into it. He found an ia64 expert who could help with the stack munging, and make scheme continuations work on ia64. Given that the failure in building guile is in the unwind-protect test, I would not at all be surprised if the same is true: that guile has never really worked on ia64 (at least, continuations have not); and, I would not at all be surprised in the work which make scm run on ia64 would not also help guile. See bug #335980 for the addresses and an intro to the solution for the scm problem. However, it will still be a while before this actually gets into a guile release, I would imagine, if it is not a red herring. Hence this heads-up. Thomas PS: Please keep the bug addresses above on replies as appopriate; also, I do not read debian-ia64 so if you want me to get a reply, keep me in the list of recipients explicitly.
