guile on HP-UX IA64

guile on HP-UX IA64

[Steve Ellcey]

I have been attempting to build guile 1.6.7 on an HP-UX 11.23 IA64
system.  I ran into a couple of problems because there are some __ia64__
ifdefs in the libguile code and these seem to have been done for Linux
and don't necessarily work on HP-UX.  The main problem I have run into
so far is the direct access of the ucontext_t structure via field
accesses.

HP-UX, starting at 11.23, has decided to make this an opaque type and
provides various accessor routines to get at the data.  These routines
are in the libuca library, not in libc.

Anyway, my thought about fixing this was to change the the __ia64__
ifdefs to IA64 and to set IA64 in libguile/gc_os_dep.c only if both
__ia64__ is set and if LINUX is set.  GCC does not set IA64 by default
like it does __ia64__.  This way IA64 is not set for HP-UX and libguile
seem to build OK.  I was able to build libguile but then I eventually
died with the attached failure.

I have not contributed to guile before so I do not have a copyright
assignment on file for guile (I do for GCC, binutils, glibc, and gdb)
but maybe this change is small enough to do without it?  Or else someone
else can make the change based on my description above.  I have
subscribed to guile-devel so I will get email sent to the list.

Apparently, CVS HEAD and 1.7.2 already fix this:

  http://savannah.gnu.org/cgi-bin/viewcvs/guile/guile/guile-core/libguile/gc_os_dep.c?rev=1.24&content-type=text/vnd.viewcvs-markup

Is it correct?

Ludovic.

I don't think it is.  While gc_os_dep.c was changed to set IA64, the
continuations.c, gc-malloc.c, gc-mark.c, gc.c, and threads.c files still
appear to have ifdef's based on __ia64__ instead of IA64.  I didn't try
to build the latest CVS sources but I don't see how guile could build
with these ifdef's on HP-UX.
