Hi 

I built a cross compiler and compiled a toy program, but I got a error like 
this: 
/home/student/wangy/eCos-arm-elf/H-i686-pc-linux-gnu/arm-elf/bin/ld: cannot 
open crt0.o: No such file or directory 
collect2: ld returned 1 exit status 

My cross compiler was under 
/home/student/wangy/eCos-arm-elf/H-i686-pc-linux-gnu/bin, I built the cross 
compiler with the help of this document: 
http://sources.redhat.com/ecos/tools/linux-arm-elf.html 
but the versions of the components wad not what it provided, while I 
couldn't find them, I choose some upper release: 
binutils-2.13.tar gcc-g++-2.95.2.tar.bz2  gcc-core-2.95.2.tar.bz2 
insight-5.2.1.tar.bz2 
gdb-5.2.1.tar.bz2 

Someone told me that maybe it was because I haven't install the glibc(or 
newlib), but in the toy c program, I did not use any lib function! The c 
program was:  

int main()
{
        return 0;
}

In addition, in the document 
"http://sources.redhat.com/ecos/tools/linux-arm-elf.html ", the newlibc or 
glibc was not required while build the toolchain, but in the ajunct file 
which also talks about how to build a arm toolchain, the glibc was 
required.
I tried to build the glibc, I config and make the glibc with the command:
> ../glibc-2.2.4/configure --target=arm-elf 
--prefix=/homex/student/wangy/arm-elf-toolchain/arm-elf --enable-add-ons
> make 
but I got a error like:

What to do now? 

Thanks for your help!
