Hi Ulrich,

thank you for your help.

Yes, it is.  So it's time for a new kernel, isn't it?

_____________________________^_________________________^  This have to be '='s?

I'm a bit confused here.  There already is

gcc -nostdlib -nostartfiles -o /home/jochen/glibc-2.2.4-build/io/test-lfs \
-Wl,-dynamic-linker=/lib/ld-linux.so.2 
/home/jochen/glibc-2.2.4-build/csu/crt1.o \
/home/jochen/glibc-2.2.4-build/csu/crti.o `gcc --print-file-name=crtbegin.o` \
/home/jochen/glibc-2.2.4-build/io/test-lfs.o \
-Wl,-rpath-link=/home/jochen/glibc-2.2.4-build:/home/jochen/glibc-2.2.4-build/math:
 \
/home/jochen/glibc-2.2.4-build/elf:/home/jochen/glibc-2.2.4-build/dlfcn: \
/home/jochen/glibc-2.2.4-build/nss:/home/jochen/glibc-2.2.4-build/nis: \
/home/jochen/glibc-2.2.4-build/rt:/home/jochen/glibc-2.2.4-build/resolv: \
/home/jochen/glibc-2.2.4-build/crypt:/home/jochen/glibc-2.2.4-build/linuxthreads
 \

`gcc --print-file-name=crtend.o` /home/jochen/glibc-2.2.4-build/csu/crtn.o

Am I to replace -Wl.-dynamic-linker=/lib/ld-linux.so.2 with
the options you've given above?  Sorry for these rather
elementary questions, but I'm not very familiar with
debugging yet.

Thank you for your time,
Jochen
