-bash-3.2# valgrind -v -d /bin/date
--1059:1:debuglog DebugLog system started by Stage 1, level 1 logging

valgrind: failed to start tool 'memcheck' for platform 'ppc32-linux': No
such file or directory

The install path on my host is /work/rber/eldk-4.2-ppc_4xx/ppc_4xx
On my target this is /

I hacked this by:

mkdir -p /work/rber/eldk-4.2-ppc_4xx/ppc_4xx/lib
ln -sf /lib/valgrind /work/rber/eldk-4.2-ppc_4xx/ppc_4xx/lib/valgrind

I guess this should be fixed for cross debugging, or maybe I should use
some additional --{?} in configure to tell valgrind where the find the
stuff on the target.

Followed by:

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:
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:
valgrind:  Cannot continue -- exiting now.  Sorry.

I'll try to install the glibc with debuginfo as indicated here:

http://lists.denx.de/pipermail/eldk/2010-June/001505.html

.. but so far without much success.

In worst case I will need to rebuild the glibc with an unstripped ld.

Robert
