[Linux-ia64] can't compile on x86 - building cross-compiler for ia64 getting SIGSEGV

[k Macy]

Is it actually possible to cross-develop from x86?

This must have been answered before, but I did not
see any way to search the posts to this list.
> ./configure --prefix=/usr/local/ia64
--host=ia64-hp-linux; gmake 

gives me:
cc1: Internal error: Segmentation fault
on both gcc-3.0 and gcc-3.0.1

The snapshot distributed from HP with nue fails
building both 2.4.5 and 2.4.9 with:
/home/kmacy/linux/include/asm/hw_irq.h:122: 
Internal compiler error in `pushdecl', at
c-decl.c:2310
Please submit a full bug report.
See <URL:http://www.gnu.org/software/gcc/bugs.html>
for instructions.
gcc: Internal compiler error: program cpp got fatal
signal 13

Current gcc code will not cross compile from ix86 to ia64, it gets
problems with conditional return of 64 bit values in some functions.
Disabling optimization for some directories avoids the problem, but is
too messy as a long term solution.  Report the bug to gcc.

It looks like in both cases it was my fault,
when building the compiler I set the --host=ia64...
when it should have been --target=ia64...
When building 2.4.9 I hadn't downloaded and applied
the latest patches to the tree. The default IA64 in
the linux tree is pretty broken.

In both cases the compiler should have failed a lot 
more gracefully, but it sounds like 32bit->64bit
cross-compilation is non-trivial.

Thanks.
