Hello all,

	I want to compile and build the gcc ( cross compiler) for m68k-coff on
Linux.
	I successfully built the cross compiler by using the FAQ provided by the
www.obsw.com and running the shell script. But i want to build the tools one
by one and I got the errors as below.

	I performed the following.

/home/kc> mkdir build-bin
/home/kc> cd build-bin
/home/kc/build-bin>
../binutils-2.9.1/configure --target=m68k-coff --prefix=/home/kc/gnu-tools

....
/home/kc/build-bin> make all install
/home/kc/build-bin> mkdir ../build-gcc
/home/kc/build-bin> cd ../build-gcc
/home/kc/build-bin>
../gcc-2.95.2/configure --target=m68k-coff --prefix=/home/kc/gnu-tools --wit
h-local-prefix=/home/kc/gnu-tools --with-newlib --enable-languages="c"

..... successfully

Could any one point me where can i get these header files in order to
compile the gcc ?

Thanks for any help

Hi, Mahadev.
I'm also works with m68k-coff, and succeed build on my windoze.
The problem you got is lack of header files, because gcc needs
them to build libgcc.a. Therefore, get newlib package and put
them in the directory the same as gcc (/home/kc), and run
configure script of gcc again. If you have put newlib in
other directory, it's ok, using
'--with-header=/somewhere/newlib/libc/include' with
configure script of gcc.

RE: gcc-m68k cross compiler problem gcc2.95.2

[Mahadev K Cholachagudda]

Thanks Mike,
It worked.

But now i have written a sample program to test this.

#include <stdio.h>

int main( void )
{
	printf("\nHello World");
	return 0;
}

When i compile the program  using "m68k-coff-gcc hello.c".
But i got the error as below.

What i did was, i wrote a linker script by using the example script. At that
point the entry point is not a main(). I got the appropriate executable.

Can some body tell me how to work around the above problems ?.

I think if i execute gcc to get me the final executable file, the gcc will
intern call pre-processor, c-compiler, assembler and then linker. I think
the linker may not be getting correct linker script or the above definitions
such as (hardware_init_hook etc) are not there in the linker script which ld
is looking for.

Am i correct ?

Yes, you are.
Just look at the ld.info documentation (part of binutils package) to
study how the linker takes your script and which commands you can use to
write this script.
Your command line to compile should look like that (if your linker
script is named "hello.ld"):
m68k-coff-gcc -Wl,--script=hello.ld hello.c
Moreover, as your gcc compiler do not link with a default C standard
library, I think you did not generate and install correctly the newlib
package.
That's why reference to atexit, printf, _exit and _cleanup symbols
are unresolved.
Your gcc compiler should automatically (without adding any option to
the m68k-coff-gcc invocation) link your executable file with the libc.a
or libg.a.
Check the presence of these libraries under:
<your-installation-directory>/m68k-coff/lib
For __FINI_SECTION__ and __INIT_SECTION__ sections, you should have
defined them into your linker script.
For software_init_hook and harware_init_hook symbols, I don't know.
Regards,
Pierre.

Hello all,

	I want to compile and build the gcc ( cross compiler) for m68k-coff on
Linux.
	I successfully built the cross compiler by using the FAQ provided by the
www.obsw.com and running the shell script. But i want to build the tools one
