Hello,
thank you very much for your reply.
Since, as I've written before, I'm new to Linux could you please explain
to me how I can actually do the two options?
- _you need to provide debug symbols for it_
If I've well understood I should install the library libc6-dbg on the
board but where can I find this library for ARM / Angstrom platform?
- _you need to either stop your ld.so getting stripped in such a severe way_
What do I have to do to stop ld.so?
Thank you again for your help
Giuseppe

I'm trying to install Valgrind on an embedded linux platform (Angstrom

I've cross-compiled it Valgrind correctly but when I try to launch it
(valgrind ls -al) on the board I have the following error:
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:
valgrind: A must-be-redirected function
valgrind: whose name matches the pattern: memcpy

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: that exports the above-named function using the standard
valgrind: calling conventions for this platform. The package you need
valgrind: to install for fix (1) is called
valgrind:
valgrind: On Debian, Ubuntu: libc6-dbg
valgrind: On SuSE, openSuSE, Fedora, RHEL: glibc-debuginfo

valgrind: Cannot continue -- exiting now. Sorry.
Could you please tell me how I can fix this problem?
I believe the answer to your question is in the verbose message which
valgrind printed...
To reiterate, you need to either stop your ld.so getting stripped in
such a severe way, or you need to provide debug symbols for it.
