cross gcc -3.0.1 building for mips

[manjunatha <msrinivasan at celestialsys dot com>]

Hi
  I am  trying to build cross gcc  for mips. I have followed following 
steps:

1. Building binutils (binuitls - 2.17)
2. Building bootstrap gcc ( gcc- 3.0.1)
3. Building uClibc ( 0.9.27)
4. Building  final gcc ( gcc-3.0.1)

Iam  successful in building first three  steps (upto building uClibc).  

My bootstrap gcc configuration is :
  
# ../gcc-3.0.1/configure --target=$TARGET --prefix=$PREFIX 
--without-headers --with-newlib --with-gnu-ld --with-gnu-as 
--enable-languages=c --disable-threads --disable-shared --disable-nls

Building as:
   # make all-gcc

Installing as:
  # make install-gcc

Then I successfully built uClibc with  bootstrap cross gcc.

final  gcc configuration:
# LD=mips-linux-ld AS=mips-linux-as ../gcc-3.0.1/configure 
--target=$TARGET --prefix=$PREFIX --enable-languages=c,c++ 
--with-headers=/root/Project-uClibc++/Genesis/tools/usr/mips-linux-uclibc/usr/include 
--with-libs=/root/Project-uClibc++/Genesis/tools/usr/mips-linux-uclibc/usr/lib 
--with-gnu-as --with-gnu-ld --enable-shared --disable-nls

I need c++ support to build the apps. library  by uClibc++.

tried to  build as :  make LD=mips-linux-ld AS=mips-linux-as  all
      
My uClibc library  and  header is located at 
/root/Project-uClibc++/Genesis/tools/usr/mips-linux-uclibc/usr/lib and 
/root/Project-uClibc++/Genesis/tools/usr/mips-linux-uclibc/usr/include.

Iam  successful in building  final gcc with  C language only 
(enable-language=c).  It is  failing of building libstdc++. I am getting 
following error as below:

let me know what may  be  reason, can I check with  gcc-3.0.4.
