RE: gcc-m68k cross compiler problem gcc2.95.2

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.

[root@Linux-Test sample]# ../bin/m68k-coff-gcc test.c

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 ?

Thanks for any help,

With best regards,
