Ok everyone...as I've said I am trying to build a GNU-C 68K cross compiler
that runs under i486 Linux.  In an effort to help out anyone who is doing the
same and to help get answers to the problems I haven't solved I'm publishing my
progress so far and how I got there.
 
The host system is a 486-33, Linux kernal 1.1.50 with gcc2.5.8 installed
 
*.  Obtained binutils2.4, GCC 2.6, GAS 2.3 from Infomagic Linux CD
 
*.  Obtained crossgcc-2.6.0.patch.gz and newlib-1.6.tar.gz from ftp.cygnus.com
 
*.  Applied crossgcc-2.6.0.patch.gz to GCC 2.6
 
*.  Did a "./configure --target=m68k-aout --host=i486-linux --with-gnu-as
    --with-gnu-ld"  on binutils, gcc and gas directories with no 
		error messages.
 
*.  Built binutils, it failed because SIGEMT wasn't defined in the Linux
    signals.h file.  I added a dummy definition to signals.h to keep the 
		build happy and re-ran make.
 
*.  Now the binutils build dies on linking objdump due to missing _frexp.  
    I add a -lm to the compile line for objdump and it links ok.  The 
		remaining build of binutils finishes without error.
 
*.  Built GAS, it builds normally and without errors.
 
*.  Did a "make install" in both GAS and binutils directories.  
    The /usr/local/m68k-aout directory is filled in apparently ok.
		
*.  Created "/usr/local/m68k-aout/includes" directory and copied all the 
    newlib include files over into it.
		
*.  Entered the GCC directory and did a "make LANGUAGES=c"
 
*.  After a very long compile cycle it comes to building cross-test.c  The 
    compile goes ok but the link bombs out with the error:
		/usr/local/m68k-aout/bin/ld: target cross-test not found
		
I am not sure what the above error means yet, a cursory search of the
documents and readme files didn't give me any immediate clues (but I am 
going on to search other resources).  Attempts to compile a simple "hello
world" program fail due to ld being unable to find crt0.o but I expected
this to happen at some point.
 
Obviously, I need to provide crt0.o or a suitable "stand in" before I can
complete the build of the GCC cross compiler and build newlib, this I know
how to do.  But does anyone know what the "target cross-test not found"
error mentioned above means?
 
Thanks to the folks at Cygnus who pointed me to the patches and newlib on
their ftp site.  By the way I did consider just buying support from you guys
but I didn't see many of the configurations we need in your online brochure.
Specifically what I need to suport is all combinations of the following
hosts and targets:
 
Hosts needed:   i486-Linux, DOS, SGI Irix5.2
Targets needed: DOS (32 bit flat model DOS extender support a must!)
                68020/68881 embedded CPU
								
Two-machine remote debugging support a major plus.
