Re: help building cross compilation ia32 to ia64

This normally means using the current native $build/$host GCC to compile the $target
binutils and the $target GCC from their sources, the FSF GCC release sourcess being
preferred. The current ones are 'binutils-2.17' and 'gcc-4.1.1', but for a Linux target the
"Linux binutils" sources, '' at '' are recommended....

You seem to need also GDB, so producing it from its sources is required.

We have downloaded the following tar-balls from from i686 package:

Are these correct binaries or do we need to get them from ia64 package?
Never heard about this "", what on earth it is?
Do we need to download something else?
Although one needs to produce the $host-to-$target crosstools, one usually doesn't need
to rebuild the existing target libraries. If the $target system, for instance "RedHat 7.1/ia64"
there also exist the prebuilt target libraries: 'glibc', 'X11-libs', 'gtk' etc. for it !

So the sources for binutils, GCC and GDB plus all the required prebuilt target libraries are

Do we need to have a certain combination of tools to build cross
compiler? If yes, have we downloaded the right combination?
Your 'ia64' or "Itanium" isn't very well supported in the Linux distros nowadays, the last I
remember seeing among the mainline distros is that "Red Hat Linux 7.1 for ia64". The
'amd64' or 'x86_64' 64-bit CPU has replaced it totally among the 64-bit PCs... The WinNT4.0
probably was the last Windoze for that too...

Although your 'ia64-linux-gnu' Linux distro would be old, with 'glibc-2.2.2' or something,
the current binutils and GCC sources shouldn't care... But always consulting the nice GCC
manuals, in this case the "Installing GCC", is highly recommended! If the "Target Specific
Install Instructions" tell something about the 'ia64-*' targets, that should be read!
