gcc crosstool chain with soft floating point support for arm9 + java

Thu Nov 27 13:42:00 GMT 2008

Hi 
I am using crosstool 0.43 to generate crosstool for arm9 with soft float,
with c,c++,java 
languages support.
demo-arm-softfloat.sh file is as below 
set -ex
TARBALLS_DIR=$HOME/downloads
RESULT_TOP=/opt/crosstool
export TARBALLS_DIR RESULT_TOP
GCC_LANGUAGES="c,c++,java"
export GCC_LANGUAGES
mkdir -p $RESULT_TOP
eval `cat arm-softfloat.dat gcc-3.3.6-glibc-2.3.2.dat` sh all.sh --notest
echo Done.
arm-softfloat.dat file has 
KERNELCONFIG=`pwd`/arm.config
TARGET=arm-softfloat-linux-gnu
TARGET_CFLAGS="-O"
GCC_EXTRA_CONFIG="--with-float=soft"
GCC_CORE_EXTRA_CONFIG="--with-float=soft"
GLIBC_EXTRA_CONFIG=" --without-fp"
GLIBC_EXTRA_CC_ARGS="-msoft-float"
gcc-3.3.6-glibc-2.3.2.dat` file has 
BINUTILS_DIR=binutils-2.15
GCC_DIR=gcc-3.3.6
GLIBC_DIR=glibc-2.3.2
GLIBCTHREADS_FILENAME=glibc-linuxthreads-2.3.2
LINUX_DIR=linux-2.6.9
LINUX_SANITIZED_HEADER_DIR=linux-libc-headers-2.6.12.0
And getting the below error

I have tried gcc-4.0.1 gcc-4.1.2 gcc-3.3.6 gcc-3.4.5 
for all of them i get , this kind of error , where in part of the librarries
get compiled 
for soft flaot and some part gets compiled with hard floating point.
Can u please guide me which all flags i missing for the compilation.
