cross-compier with gcc

cross-compier with gcc

[Hua Ji]

Hi, guys,

Good morning!

Help needed!

I made a cross compiler on my solaris machine for powerpc-elf target.
Everything looks fine when I did the make.

When I used my powerpc-elf-gcc to compile and link my helloworld.c, I got
some error described below. Basically,
my helloworld.c is:
--------
#include <stdio.h>
void main()
{
	printf("Hello World!\n");
}
--------

The command line used for compile and link is: powerpc-elf-gcc -v -o
helloworld helloworld.c

The error is: Can't link printf codes from library!!

---------
GNU assembler version 2.9.1 (powerpc-elf), using BFD version 2.9.1

Thanks, guys.

You need to configure for "powerpc-linux", and build a glibc.
