Re: help about cross-compiler

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

Hi.
Long time not ask questions .
Thanks for your help .
I have tried m68k-coff & m68k-elf . Both are failed .
I don't know why I cann't succeed .
This is all that I've done in m68k.
Used  tools:
    sparc-sun-solairs2.6 make 3.79 , binutils-2.11.2 , newlib-1.9.0 ,
gcc-2.95.3 .
modify the path, added path : /home/yliu/local/bin $path in .cshrc 
(because
I use cshell)

build script:
     cd ../bin-m68kcoff



  ../binutils-2.11.2/configure --target=m68k-coff --
prefix=/home/yliu/local;
     make all install > ../make/m68kcoffbin.txt

    cd ../gcc-core-m68kcoff




../gcc-2.95.3/configure --target=m68k-coff --prefix=/home/yliu/local --
enabl
e-language=c
    --with-local-prefix=/home/yliu/local/m68k-coff --without-headers --
with-
newlib
    --disable-shared --with-gnu-as --with-gnu-ld;
    make all-gcc install-gcc > ../make/m68kcoffcore.txt ;

   cd ../newlib-m68k-coff
   ../newlib-1.9.0/configure --target=m68k-coff --prefix=/home/yliu/local;
   make all install > ../make/m68kcoffnewlib.txt;

  cd ../gcc-cross-m68kcoff ;


../gcc-3.0/configure --target=m68k-coff --prefix=/home/yliu/local --
enable-l
anguage=c,c++
   --with-local-prefix=/home/yliu/local/m68k-coff --with-gnu-as --with-
gnu-l
d;
   make all install > ../make/m68kcoffcross.txt;

I have checked the output , it seemed I have succeed in
building bin,core,newlib. Because the three
files($prefix/bin/m68k-coff-ld,$prefix/bin/m68k-coff-gcc,$prefix/bin/
$target
/libgc.a) exist.

But in directory ../gcc-cross-m68kcoff/libiberty, the Makefile exists !!
So what's wrong with it? I really cann't find the reason.
I think I have done every thing that descripted in a script from
http://crossgcc.billgatliff.com .
Maybe my environment is wrong?  Or some other things?

 I have tried target mips because actually I will use mips.
Unfortunately failed again ( Why I am so unfortunate ?  :-)  ).
What I 've done is same as what I did in m68kcoff and I get the same error
information.
 I hope someone can help me to find the reason.

Because I must make a platform for mips .
Anybody can help me or give me some advice in debugging mips under
sparc-sun-solaris2.6 as what you do
to help me build m68k?
Thanks again!

Best Regards
Yong Liu
