Subject: Emacs 23.3 and 24.0.90 don't build on IRIX 6.5
Date: Thu, 06 Oct 2011 16:19:30 +0200

I've recently tried to build current emacs versions on IRIX 6.5
(6.5.30f, actually), but always failed in the same way.

The latest attempt was like this:

* Configure emacs 24.0.90 with

  /vol/src/gnu/emacs/emacs-24.0.90/configure --prefix=/vol/gnu --infodir=/vol/gnu/info --mandir=/vol/gnu/man --libexecdir=/vol/gnu/lib --localstatedir=/vol/gnu/share/emacs/var --with-xpm=no --with-jpeg=no --with-png=no --with-gif=no --with-tiff=no

* Build it with gcc 4.6.0 with make -j8.

  The C part of the build complete successfully, but then it fails like
  this:

Dumping under the name emacs
41988 pure bytes used
cd ../lisp; make -w --jobserver-fds=3,4 - --jobserver-fds=3,4 -j compile-first EMACS=/vol/obj/gnu/emacs/emacs-24.0.90/src/bootstrap-emacs
make[2]: Entering directory `/vol/obj/gnu/emacs/emacs-24.0.90/lisp'

make[2]: Leaving directory `/vol/obj/gnu/emacs/emacs-24.0.90/lisp'
cd ../lisp; make -w --jobserver-fds=3,4 - --jobserver-fds=3,4 -j autoloads EMACS=/vol/obj/gnu/emacs/emacs-24.0.90/src/bootstrap-emacs
make[2]: Entering directory `/vol/obj/gnu/emacs/emacs-24.0.90/lisp'

emacs: Invalid function: make-local-variable
make[2]: *** [compile-onefile] Error 1
make[2]: Leaving directory `/vol/obj/gnu/emacs/emacs-24.0.90/lisp'

I have no idea what might cause this; emacs 23.2 built fine and mostly
works.  For emacs 23.3, I tried several variations:

* build with gcc 4.4.2

* build with gcc -g3 -O0 instead of the default -g -O2

* build with SGI MIPSpro cc 7.4.4m

None of those makes a difference.

Does it help to drop the -j8 switch to Make?

And what version of GNU Make is that, btw?

If you have an SGI IRIX, maybe you could help out with
http://debbugs.gnu.org/cgi/bugreport.cgi?bug=7643 ?

The original submitter never replied.

Though presumably you don't see that problem since the C build completed
for you (also I'm not sure if you are using the same kind of system).

Thanks!

The same one that worked for 23.2 and all my GCC bootstraps.

Can you run any of these 2 commands under a debugger, put a breakpoint
in a function called xsignal1, and when it breaks, show the backtrace?
Preferably do this with GDB, and start GDB from the src directory, so
it reads the .gdbinit file there.  Also, please recompile Emacs
without the -O2 optimization switch, so that information shown by the
debugger would be reliable.

Thanks.

Of course: recompiled with -g3 -O0.

Unfortunately, they don't really work:

Breakpoint 3, xsignal1 (error_symbol=274352730, arg=274355066) at /vol/src/gnu/emacs/emacs-24.0.90/src/eval.c:1773

(gdb) pp args[0]
Address of symbol "print_output_debug_flag" is unknown.
(gdb)pp args[1] 
Address of symbol "print_output_debug_flag" is unknown.

This is really strange, though:

ro <at> columba 221 > nm print.o|grep print_output_debug_flag
[44]    |         0|       4|OBJT |GLOB |DEFAULT  |3      |print_output_debug_flag

[2868]  | 273886352|       4|OBJT |GLOB |DEFAULT  |MIPS_SCOMMON|print_output_debug_flag

Since the save/restore of print_output_debug_flag seems to be for the
benefit of w32 only, I've tried the following instead:

Breakpoint 3, xsignal1 (error_symbol=274352730, arg=274355066) at /vol/src/gnu/emacs/emacs-24.0.90/src/eval.c:1773

(gdb) set $tmp = fun
(gdb) set safe_debug_print ($tmp)
emacs: Invalid function: external-debugging-output
[Inferior 1 (process 24041591) exited with code 01]
The program being debugged exited while in a function called from GDB.
Evaluation of the expression containing the function
(safe_debug_print) will be abandoned.
(gdb) frame 1
No registers.

Seriously ugly.  This is all gdb 7.3, so nothing newer to try (except
perhaps for gdb mainline).

Maybe there's a problem with dumping, can you try running the above
command and using the  ../src/temacs binary instead of ../src/emacs ?

Then you will have to do it the hard way:

 (gdb) p fun
 (gdb) xtype

Then use the relevant x* commands, depending on what xtype says.
E.g., if it says that fun is a cons cell, use xcar and xcdr to display
the components, then xtype again for each component, etc.

But before you get down to all this mess, it would be good to use
Dan's suggestion first.

One possibility is that it's a garbage collector bug.
You might try commenting out this line in src/s/irix6-5.h:

#define GC_MARK_STACK GC_MAKE_GCPROS_NOOPS

and building from scratch.  If this fixes the problem,
we can investigate what went wrong in stack-marking
(though that won't be fun).

yes, using temacs instead works fine (but slooow, of course).

Any suggestions on how to best investigate undump failures?  I'll first
try both SGI MIPSpro cc and older gcc releases (3.4, 4.4) to check if
they make a difference.

Thanks.

I've just tried building 24.0.90 with gcc 3.4 and MIPSpro cc:

I haven't tracked this down yet, and it's certainly another bug.

I don't think there have been too many important changes in the dumping
infrastructure, so if something broke is probably an oversight.

You can try compiling a version of emacs that is known to work.
Compile the bzr trunk with the same compiler + flags (maybe use just -O0).
Compare the two "emacs" binaries, use readelf to compare the elf
sections, maybe there's something obvious. 
Compare the two versions of unexelf.o, and maybe the corresponding
preprocessed files (there shouldn't be many interesting differences).
Try linking the trunk temacs with the old unexelf.o and see if you
get better behavior.

as an intermediate datapoint: while looking for a version of emacs that
built correctly, I found that even 23.2 didn't when using gcc 4.4 or
3.4.  Fortunately, I had a 9 years old copy of gcc 3.1 around, which was
able to build both a working emacs 23.2 and 24.0.90 (from the tarball).

I'll start digging deeper from here, but it may take a bit.

Have you been able to make any progress with this?
We hope to release Emacs 24.3 in the not-too-distant future, and it
would be nice to fix this there, if possible and appropriate.

If you are not able to look into this, it's fine, since you seem to be
approximately the only person using Emacs on IRIX these days, so don't
feel pressured to spends ages on it. :)

not really: I've just tried to build emacs 24.2.92 and see similar
successes and failures as with 24.0.90:

* building with gcc 3.1 and MIPSpro 7.4.4m cc produces a working emacs

* building with gcc 3.4 or 4.6 yields the same error as before.

I suppose I'll be content with having a gcc 3.1-built emacs 24.3 if need
be.  Given that gcc 4.7 was the last release to support IRIX 6.5, I've
not much time for IRIX issues left.

I recently got access to an IRIX 6.5 host and ported the emacs-24 branch 
to it; see emacs-24 bzr 116961.  So this bug should be partly fixed in 
the next version of Emacs.  I say "partly" because I got it to work with 
IRIX cc but not GCC (some problem with undumping).

Time to close this as wontfix, since Emacs 26 NEWS has:

    ** Emacs no longer works on IRIX.  We expect that Emacs users are not
    affected by this, as SGI stopped supporting IRIX in December 2013.
