Valgrind fails to run on osmc

Help and Support Raspberry Pi

Hi,

when running valgrind to find cause of segmentation fault in a program compiled on OSMC, valgrind bails out with a fatal error:

$valgrind ./a.out
==12089== Memcheck, a memory error detector
==12089== Copyright (C) 2002-2017, and GNU GPL’d, by Julian Seward et al.
==12089== Using Valgrind-3.14.0 and LibVEX; rerun with -h for copyright info
==12089== Command: ./a.out
==12089==

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: index
valgrind: in an object with soname matching: ld-linux-armhf.so.3
valgrind: was not found whilst processing
valgrind: symbols from the object with soname: ld-linux-armhf.so.3
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. 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:
valgrind: Note that if you are debugging a 32 bit process on a
valgrind: 64 bit system, you will need a corresponding 32 bit debuginfo
valgrind: package (e.g. libc6-dbg:i386).
valgrind:
valgrind: Cannot continue – exiting now. Sorry.

steps to reproduce (minimalistic example)
compile following program (main.c)

#include <stdio.h>
int main()
{
printf(“Hello, World!”);
return 0;
}

compile using gcc main.c
then run valgrind ./a.out

$ ./a.out

Hello, World!

Any suggestion how to fix this?

(re)installing libc6-dbg does not fix this issue…

P.S. I searched the forum(s) and osmc’s github and only found one issue mentioning valgrind and that was from 2016, so I considered that unrelated.

I have used valgrind successfully on OSMC some time ago (last year?)

It would help to know which model of Pi you are using.

Nothing obvious. My initial suspicion was you were using Pi 4 (aarch64 kernel; armhf userland); but this doesn’t seem to be the case.

Maybe Valgrind is too old for the kernel and needs building from source.

You could try using strace to see exactly what invokes that message.

running strace valgrind ./a.out gives

from https://valgrind.org : valgrind current release: Valgrind 3.18.1
installed valgrind version:
valgrind --version
valgrind-3.14.0

build from source following instructions found at

git clone git://sourceware.org/git/valgrind.git
cd valgrind
./autogen.sh
./configure
make
Then run the vg-in-place binary built at the root of the clone.
./vg-in-place ./a.out results in same error
