Problem in building a cross-compiler for powerpc (gcc 3.3)


Hi all,
I've got a problem in building a cross compiler for an IBM powerpc.
I successefully built the binutils (versione 2.13.92) and installed them under 
the ~/cross_compiler/Sources/install directory.

I've then built the glibc 2.3.2 library using a minimal gcc build and 
installed it under my ~/cross_compiler/Sources/inst_glibc directory.

I've finally tried to build the real fully-featured gcc (version 3.3) 
specifying the new built glibc as target libraries.

The process runs for a while but it stops when it checks if the xgcc works.
Looking at the 
~/cross_compiler/Sources/build-real-gcc/powerpc-linux/libiberty/config.log 
I've noticed the compiler complain for some missing libraries.
This is a snippet of the problem:

It seems to look for the file ld.so.1, needed by 
/home/lapo/cross_compiler/Sources/inst_glib/lib/libc.so.6.

But the file is in the same durectory as for libc.so.6

[lapo@localhost libiberty]$ file 
/home/lapo/cross_compiler/Sources/inst_glib/lib/ld.so.1
/home/lapo/cross_compiler/Sources/inst_glib/lib/ld.so.1: symbolic link to

/home/lapo/cross_compiler/Sources/inst_glib/lib/ld-2.3.2.so: ELF 32-bit MSB 
shared object, PowerPC or cisco 4500, version 1 (SYSV), not stripped

I've also tried not using the --with-sysroot option at all when I configured 
the gcc, with no luck.

Can somebody help me in this problem.

Thanks.
	Lapo
