I am also running Redhat 5.1, and installed the binutils and gcc sources
via the 5.1 cd. When I tried to
follow the instructions for cross compiling I got:
[root@razoo gcc-2.7.2.3]# ./configure
--prefix=../binutils-2.9.1.0.4/binutils --targ
This appears to be a i586-unknown-linux system.
... stuff deleted...
Merged h8300/t-h8300.
Created `cp/Makefile'.
Links are now set up to build a cross-compiler for h8300-hitachi-hms
from i586-unknown-linux.
(so it looks like it is set up for the Hitachi)
[root@razoo gcc-2.7.2.3]# make LANGUAGES=c

So I tried your trick with the make -k and got further, but could not
"make install"
and so I moved the files to the proper location by hand. Now I try to
compile
the demos now I get stuff like:
/tmp/cca08929.s:39: Error: invalid character '.' in opcode
/tmp/cca08929.s:40: Error: no such 386 instruction: `bne'

/tmp/cca08929.s:53: Error: invalid character '.' in opcode
/tmp/cca08929.s:55: Error: no such 386 instruction: `rts'
It looks like the assembler i may still in be i386 mode or something.
I have no experience with cross compiling, is there a step that
I might be missing? Any assistance appreciated Thanks -- Bobby
