RE: help about cross-compiler

["Liu Yong" <yliu at newavetech dot com>]

Hi.
I think I haven't made things clear.
I have succeeded in building core-gcc as you described 
in your mail.
And succeeded building newlib.
But failed to build cross-gcc,the last step.
That's what I typed in building cross-gcc:

[prompt$] ./configure --target=m68k-hp-bsd4.3 --prefix=/home/yliu/local
 --with-gnu-as   --with-gnu-ld
[prompt$]  make all install

The error is :

checking whether the C compiler
(/home/yliu/program/forchen/gcc-3.0/gcc/xgcc
 -B/home/yliu/program/forchen/gcc-3.0/gcc/ -B/home/yliu/local/m68k-hp-
bsd4.3/bin/ -B/home/yliu/local/m68k-hp-bsd4.3/lib/ -
isystem /home/yliu/local/m68k-hp-bsd4.3/include -g -O2 )
works... no
configure: error: installation or configuration problem: C compiler
cannot create executables.
make: *** [configure-target-libiberty] Error 1

I have looked at the directory /home/yliu/local/m68k-hp-bsd4.3/bin/  ,
/home/yliu/local/m68k-hp-bsd4.3/lib/ and
/home/yliu/local/m68k-hp-bsd4.3/include ,there are files in there:
bin: ar as c++ g++ gcc ld nm ranlib strip
lib: bcc.ld crt0.o idp.ld libgcc.a libdbug.a libidp.a libmvme135.a
libmvme162.a libnosys.a mvme135.ld mvme162.ld
      sbc5204.ld sbc5206.ld and a directory ldscripts that contains
hp300bsd.x hp300bsd.xbn hp300bsd.xn hp300bsd.xr
      hp300bsd.xu
include:  there is no include directory ,just a sys-include directory that
contains a file named COPIED (file length is 3 bytes, just has a 
word 'no')

So what 's wrong with it?
I am so near the success.

DANK SE

Best Regards.
Yong Liu
