Hi All,

I wanted to install gcc-3.4 on my ppc-linux m/c. I tried cross 
compiling, but cought up with error which i'm not familiar with as i'm 
new here.

The following is the error log on make:

This is how i configured :
[root@crazy gcc_build]# ../gcc-3.4.4/configure --host=ppc-linux 
--target=ppc-linux --build=i386-linux

This is how i set my cross-compiler :
export 
PATH=$PATH:/opt/WindRiver/gnu/3.4.4-wrlinux-1.3/x86-linux2/powerpc-wrs-linux-gnu/bin 

export CC=powerpc-wrs-linux-gnu-ppc7400-glibc_cgl-gcc
export CXX=powerpc-wrs-linux-gnu-ppc7400-glibc_cgl-g++
export LD=powerpc-wrs-linux-gnu-ppc7400-glibc_cgl-ld
export NM=powerpc-wrs-linux-gnu-ppc7400-glibc_cgl-nm
export AR=powerpc-wrs-linux-gnu-ppc7400-glibc_cgl-ar
export AS=powerpc-wrs-linux-gnu-ppc7400-glibc_cgl-as
export CPP=powerpc-wrs-linux-gnu-ppc7400-glibc_cgl-cpp


Please help me where i'm wrong....

Thanks
