Help hpux10.20 -> m68k-*-aout

[Ray Lillard <Ray_Lillard@eng.trimble.com>]

Ladies & Gentlemen

I just found out about this list while searching for help building
a cross hosted on hppa1.1-hp.hpux10.20 for m68k-*-aout.  I'm sure
coff would be OK too.  My actual target is a m68332.

My most recent effort and what I will describe here is taken from
the embedded FAQ.  I hope I haven't committed some social offence
by posting such a large message, but fire-walls and such prevent
me from putting it in some public place.

I am continuing to work on this and hope for some illumination
from the gurus on this list.

Thanks to any and all who help,
Ray




The prob:

The 'make' proceeds until it fails on the first attempts to run
the newly created 'xgcc' which core dumps due to having received
SIGABRT.  I have used gdb to determine that this is caused by
a call to xmalloc() place at line 4392 of gcc.c.  A buffer is being
allocated to process the arguments.  xmalloc() tries to access memory 
at address 0.

These is nothing sinister about the file SYSCALLS.c.  xgcc never
even gets far enough to open it.

My suspicion is some interaction between newlib and hpux, but at
this point I don't know what's going on.  There is a call to alloca()
in snapshot_warning() at line 4389 which succeeds.

from gcc.c (v2.8.1)
     4387   /* If this is a test release of GCC, issue a warning.  */
     4388   if (version_string[0] == 't' && version_string[1] == 'e')
     4389     snapshot_warning ();
     4390
     4391   argbuf_length = 10;
 --> 4392   argbuf = (char **) xmalloc (argbuf_length * sizeof (char *));
     4393
     4394   obstack_init (&obstack);


Attempting to do the one pass installation of GCC+BinUtils I have
followed the steps outlined in Sec 3.2 of the FAQ:

I have acquired and installed:
	gcc-2.8.1
	binutils-2.9.1
	newlib-1.8.1

Applied patch:
	patch-2.5

Ran:
	one-tree-1.5.sh

Made a build directory:

Configured thusly:

    ../src/configure \
	    --prefix=/opt/xgcc68k \
	    --target=m68k-*-coff \
	    --with-stabs \
	    --program-prefix=x \
	    --program-suffix=-68k \
	    --with-gnu-as \
	    --with-gnu-ld \
	    --enable-m68332
