[SOLVED] valgrind doesn't work

07 October 2022, 20:12:18

whenever i try to run valgrind, this is what i get:

==1342== Memcheck, a memory error detector
==1342== Copyright (C) 2002-2022, and GNU GPL'd, by Julian Seward et al.
==1342== Using Valgrind-3.19.0 and LibVEX; rerun with -h for copyright info
==1342== Command: ./bin/yed
==1342== 

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:      strlen
valgrind:  in an object with soname matching:   ld-linux-x86-64.so.2
valgrind:  was not found whilst processing
valgrind:  symbols from the object with soname: ld-linux-x86-64.so.2
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.

i've got debuginfod

Reboot, there is some environment variable that is set at boot, it doesn't get set on installation.

i installed valgrind ages ago, and it also used to work fine not long ago

You can check if it's set like this:

Code: [Select]

$ env |grep debug
DEBUGINFOD_URLS=https://debuginfod.artixlinux.org

You might need to be fully updated too so all the versions match with all this separate debug symbols stuff. If I try:

Code: [Select]

$ valgrind ls

it works OK here, anyway, although that is not to say there might be a problem for others of course.

It is supposed to "just work" now since we have a debuginfod. Maybe double check and make sure all of your packages are up to date and from Artix repos?

[yeti:~/dev/cc/yed] env | grep debug

[yeti:~/dev/cc/yed]

Code: [Select]

valgrind ls

Your output of DEBUGINFOD_URLS says archlinux. That's wrong. It should be artixlinux.

Unfortunately I'm out of ideas here. No clue why it's not working for you. Hopefully someone else has an idea.
