bug#11971: Emacs 24.1 fails to build on ia64 with "value as variable is void"

[Rob Browning]

Here's another unusual build failure.  This time on Debian Wheezy ia64:

  Compiling /build/buildd-emacs24_24.1+1-3-ia64-1WcbZW/emacs24-24.1+1/debian/build-x/lisp/progmodes/cc-fonts.el

  In toplevel form:
  progmodes/cc-fonts.el:76:27:Error: Symbol's value as variable is void: quote
  make[4]: *** [/build/buildd-emacs24_24.1+1-3-ia64-1WcbZW/emacs24-24.1+1/debian/build-x/lisp/progmodes/cc-fonts.elc] Error 1
  make[4]: *** Waiting for unfinished jobs....

  https://buildd.debian.org/status/fetch.php?pkg=emacs24&arch=ia64&ver=24.1%2B1-3&stamp=1342582280

Does that look familiar?

I think we probably have an ia64 porterbox, so I should be able to do
some testing when I get time.

Thanks

See http://bugs.debian.org/582439.  The Debian emacs23 package has been
compiled with -O1 on ia64 to work around this.

There may be a problem with stack marking on ia64.  Using
GC_USE_GCPROS_AS_BEFORE lets the build succeed.

What does "using" mean here?  Do you mean defining GC_MARK_STACK to
GC_USE_GCPROS_AS_BEFORE rather than to GC_MAKE_GCPROS_NOOPS?

(And Sven's probably right -- using -O1 may also avoid this failure.  I
 had removed the special-casing we had in 23 (to set -O1 rather than -O2
 on ia64), in order to see if 24 still needed it, and then forgot about
 the change.)

This discussion didn't go anywhere.

Are you saying we need to change Emacs's configure.ac to define
GC_MARK_STACK as GC_USE_GCPROS_AS_BEFORE on ia64 GNU/Linux?

You can define via CPPFLAGS, see the comment in lisp.h.

Better would be to firgure out the actual problem and see if/how we can
fix it.

Sure. But if the problem occurs on many/most ia64 platforms, obviously
we should change the default to the conservative one. Or is there
something unusual about the Debian one?

Maybe the bug has been fixed already, I couldn't reproduce it with
current trunk.

Rob, could you try the latest pretest from

http://alpha.gnu.org/gnu/emacs/pretest/

on ia64 and see if it works unmodified?

(It would be super-awesome if you could test it on _all_ the Debian archs.
Is this what experimental is for?)

It may also be a Debian-specific compiler bug, since 24.1 builds without
problem on SLES11.

More information was requested a year ago, and there are other reports
that this is working now, so I'm closing this bug report.  If this is
still a problem, please reopen.
