I just managed to build/install today's version of the valgrind trunk on
my kilauea board with eldk 4.2

Now I have the infamous problem:
valgrind:  Fatal error at startup: a function redirection
valgrind:  which is mandatory for this platform-tool combination
valgrind:  cannot be set up.  Details of the redirection are:
valgrind:  A must-be-redirected function
valgrind:  whose name matches the pattern:      strlen
valgrind:  in an object with soname matching:   ld.so.1
valgrind:  was not found whilst processing
valgrind:  symbols from the object with soname: ld.so.1
valgrind:  Possible fixes: (1, short term): install glibc's debuginfo
valgrind:  package on this machine.  (2, longer term): ask the packagers
valgrind:  for your Linux distribution to please in future ship a non-
valgrind:  stripped ld.so (or whatever the dynamic linker .so is called)
valgrind:  that exports the above-named function using the standard
valgrind:  calling conventions for this platform.
valgrind:  Cannot continue -- exiting now.  Sorry.

Before I'll try to rebuild the glibc in order to get a non stripped
ld.so I tried to do what Eric suggested.

${CROSS_COMPILE}rpm -i glib-debuginfo-ppc_4xx-1.2.10-26.ppc.rpm
${CROSS_COMPILE}rpm -i glib2-debuginfo-ppc_4xx-2.12.13-1.ppc.rpm

... but unfortunately without success.

Do I need to uninstall something before?
Eric, which rpm fixed the problem for you?

Can you please advise?
