Re: Building m68k-coff-gcc
Bill,
I've checked your site for the build instructions, thanks for the link
there. Now, I proceed according to your recommendations, but - I'm a
lazy guy - I wrote a Makefile. The make process aborts with error, when
doing a 'make all-gcc' in the compiler build directory. It tries to
build the archive:

##/snip
I think, there is some little b.. in that configure jungle: the archiver
program is called with the program suffix of the bootstrap compiler.
Below is the Makefile, there are a few options at the top, one may edit
according to his local topology.
Who in the WWW is to badmouth for such a scripting bug ? Is there a
build scripts documentation, and/or a CVS or RCS or PVCS or bitkeeper
repository somewhere in the web, one may have a look in ?

Hi, folks.
It's a strange thing: xgcc can't find stdlib.h and unistd.h, when doing
a make.
It tries to build the libgcc (m68k-coff-ar rc tmplibgcc2.a ${name}.o;)
gcc 2.95.3 has been configured with
'--target=m68k-coff --program-prefix=m68k-coff- --enable-languages=c
--host=i686-pc-linux-gnu', like the binutils were, before.
Building another cross-compiler - h8300hms - from the same sources, works.
BTW, xgcc wants to include files from /usr/local/m68k-coff/include,
which does not exist.
Any hints would be welcome ...
Sounds like the h8300's libgcc doesn't need header files, but m68k's does.
You need to build a bootstrap compiler first, then build header files
for the target, then build the full cross compiler.
