Re: Trying to build cross tool chain using egcs-980302

[Jim Wilson <wilson@cygnus.com>]

As yet, we have not had time to fix all of the cross-compiler issues in
EGCS, so it isn't as easy to build a cross compiler as it should be.

There are a number of different problems that you ran into, but most of
them seem to be version conflicts.

	When tyring to build for the RH-4.2, config.guess in egcs-980302
	declares the system to be a i686-pc-linux-gnulibc1, and gdb-4.16
	declares that an unsupported configuration: 

gdb-4.16 is two years old.  Since then, there was a change to the
configuration naming scheme which happens to affect your host.  This
was part of the support needed to handle glibc2 linux systems.  You will
not be able to use the same host name with gdb-4.16 and the current egcs
sources.  This will not be a problem with gdb-4.17 which is expected soon.

I think there is no real advantage to trying to build gdb in the same source
tree as the rest of the stuff.  Just build it separately.

	$ ../gdb-4.16/configure --host=i686-unkown-linux
	Created "Makefile" in /usr/bigdisk/pbarada/src/gdb/objdir
	../../gdb-4.16/bfd/../ltconfig: ../../gdb-4.16/bfd/../ltconfig: No such file or directory
	configure: error: libtool configure failed
	Configure in /usr/bigdisk/pbarada/src/gdb/objdir/bfd failed, exiting.

I am guessing that you use the binutils copy of bfd.  This was relatively
recently modified to use libtool.  libtool requires some scripts in the
toplevel directory which are not distributed with EGCS.  Just copy them
from the binutils toplevel directory into the toplevel EGCS directory.
I think that there are only two scripts involved here, both of which start
with lt.
