gcc 3.0 mips (elf) cross compiler problem

[patrick k <pkeshish at yahoo dot com>]

Greetings,

There seems to be a problem in building a cross compiler for (at least) the
mips target.

Using:
   binutils-2.11.2/  gcc-3.0/  gdb-5.0/  newlib-1.9.0/

Host platform:
   % uname -a
   Linux chef.xxxx.xxx 2.4.2-2 #1 Sun Apr 8 20:41:30 EDT 2001 i686 unknown

   % gcc -v
   Reading specs from /usr/lib/gcc-lib/i386-redhat-linux/2.96/specs
   gcc version 2.96 20000731 (Red Hat Linux 7.1 2.96-81)



First I configured, make and make installed the binutils for --target=mips.



Next I configured gcc-3.0 with following options:

% cat config.status 
#!/bin/sh
# This file was generated automatically by configure.  Do not edit.
# This directory was configured as follows:
../../gcc-3.0/configure
--with-gcc-version-trigger=/export/dev/gcc/3.0/mips/gcc-3.0/gcc/version.c
--host=i686-pc-linux-gnu --target=mips --prefix=/usr/local/gcc/3.0/mips
--enable-languages=c,c++ --with-newlib
--with-headers=../../newlib-1.9.0/newlib/libc/include --with-gnu-as
--with-gnu-ld --norecursion 
# 

(see attachment for a copy of configure script's output)

Next I did `make cross' which failed as follows:


make[2]: Entering directory
`/export/dev/gcc/3.0/mips/obj/gcc-3.0/mips/libiberty'

(see attachment for a copy of `make cross' output)


Note that if were to re-issue the compile line that failed and include as a
command line option -isystem /usr/local/gcc/3.0/mips/mips/sys-include/ the
compilation succeeds.


Any ideas why that directory isn't included as part of the command line?


Attached tar.bz2 file contains output from:

   configure script
   make cross
   config.status
   config.cache

The files are prefixed with `gcc-3.0'.



Thanks for all who take the time to reply,


patrick 

Btw. the GCC Cross Compiler HOWTO seems out-dated as its instructions did not
work since 2.95.2 release (at least).
