help about cross-compiler

[Vermeulen Jan]

Hi once again,


Ah... You said you are running a sun-solaris computer, so why don't you try
to do the following:

(do not change 'configure' with vi, simply add all the options on the
command line)
tar-gunzip the sources into their directories and 'make' them from another.

For your gcc-problems... It might be that your system is trying to use it's
own assembler and not the one from binutils. So it is best that you add
"--with-gnu-as --with-gnu-ld" to make sure it will use the GNU toolchain.

It is best that you build a core-gcc first, so you can build those *.a
files. (libraries)

(please have a look at http://crossgcc.billgatliff.com/ He didn't make it
just for fun, but it is actually usefull too :)

[prompt$] TARGET_LIBGCC2_CFLAGS=-Dinhibit_libc
[prompt$] ../gcc-3.0/configure --target=m68k-coff --prefix=<your directory>
--enable-languages=c --with-local-prefix=<your directory>/m68k-coff
--without-headers --with-newlib --disable-shared --with-gnu-as --with-gnu-ld
[prompt$] make all-gcc install-gcc

After that, you build newlib.
Finally, after that, you build your full gcc with the generated libraries...

At http://crossgcc.billgatliff.com/ you can find a script that does all
those things for you...
I really suggest you try it, as it will help you a lot.

Good luck,
I hope you get it working now :)
Jan

>cd /my-gcc
>/my-gcc/vi configure(change the target(m68k-hp-bsd4.3 and prefix director 
>(I am not administor) )
>/my-gcc/ ./configure
>/my-gcc/make
