Cross-compiling standard utilities for MPC823

From: Cindy Peters <hidden>

I am attempting to cross-compile the file utilities that I downloaded from
the linuxppc ftp site for the MPC823 on an x86 PC running Redhat 6.2. I am
getting an error when configure is trying to determine the byte ordering.
Following is a clip from the config.log file.

configure:2220: checking whether byte ordering is bigendian
configure:2242: powerpc-linux-gcc -c -g -O2  conftest.c >&5
configure: In function `main':
configure:2236: `bogus' undeclared (first use in this function)
configure:2236: (Each undeclared identifier is reported only once
configure:2236: for each function it appears in.)
configure:2236: parse error before `endian'
configure: failed program was:
#line 2228 "configure"
#include "confdefs.h"
#include <sys/types.h>
#include <sys/param.h>

int
main ()
{
#if !BYTE_ORDER || !BIG_ENDIAN || !LITTLE_ENDIAN
 bogus endian macros
#endif

  ;
  return 0;
}

I have tried defining BIG_ENDIAN and BYTE_ORDERING but that is not helping.
Can someone tell me what I need to do to successfully cross-compile this?
Here is the command line I am using.

AR=powerpc-linux-ar AS=powerpc-linux-as LD=powerpc-linux-ld \
  RANLIB=powerpc-linux-ranlib CC=powerpc-linux-gcc NM=powerpc-linux-nm \
  ./configure --build=i686-pc-linux-gnu --host=powerpc-unknown-linux-gnu \
  --target=powerpc-unknown-linux-gnu \
	--prefix=/opt/usr/local/powerpc-linux

Thanks,

It sounds like your cross-gcc is messed up.  Have you tried the
MontaVista one?  it should be at ftp.mvista.com/Journeyman/  however, we
are currently having problems with the FTP site.. I hope it's back up
soon.

If you're cross-compiling applications that use autoconf "configure"
scripts, you will need to set some variables to override tests that
configure is unable to perform when you're cross-compiling.

Here are some mpc8xx-specific variables:

ac_cv_c_cross=yes
ac_cv_c_bigendian=yes
ac_cv_c_char_unsigned=no
ac_cv_sizeof_long_long=8
ac_cv_sizeof_long=4
ac_cv_sizeof_int=4
ac_cv_sizeof_short=2
ac_cv_sizeof_unsigned_long=4
ac_cv_sizeof_unsigned_int=4

..and some other ones if you use glibc-2.1.3:

ac_cv_header_stdc=yes
ac_cv_func_closedir_void=no
ac_cv_func_setvbuf_reversed=no
ac_cv_func_getpgrp_void=yes
ac_cv_func_setpgrp_void=yes
ac_cv_func_mmap=yes
ac_cv_func_setpgrp_void=yes
ac_cv_func_strcoll_works=yes
ac_cv_func_vfork=yes
ac_cv_func_wait3_rusage=yes
ac_cv_sys_restartable_syscalls=yes

The variables above will make it possible to cross-compile
fileutils-4.1. Other packages (bash, readline) might need
more variables, but if you read the configure-file, you
will figure out what is missing.

Or, you can take the blue pill and go the RPM-way ... ;)
