Summary: An Open Source memory debugger for GNU/Linux.
Perl UpdatesGentoo has bumped perl from 5.20 to 5.22. Be sure to run perl-cleaner --all after the upgrade.
ARM RebuildARM systems will use new stage3's that are not compatible with earlier versions.
ABI X86 64 and 32Funtoo Linux has new 32-bit compatibility libraries inherited from Gentoo. Learn about them here.
Fatal error at startup
If you receive the following error message when you try to run Valgrind:
==23489== Memcheck, a memory error detector ==23489== Copyright (C) 2002-2013, and GNU GPL'd, by Julian Seward et al. ==23489== Using Valgrind-3.10.1 and LibVEX; rerun with -h for copyright info ==23489== Command: <some command name goes here> ==23489== valgrind: Fatal error at startup: a function redirection valgrind: which is mandatory for this platform-tool combination valgrind: cannot be set up.

it is because sys-libs/glibc (package not on wiki - please add) was built without the
debug USE flag. To enable this USE flag, you can do the following:
# mkdir /etc/portage/package.use (if it doesn't exist on your system) # touch /etc/portage/package.use/glibc # echo "sys-libs/glibc debug" > /etc/portage/package.use/glibc # echo 'FEATURES="splitdebug"' >> /etc/portage/make.conf
After making the required changes, simply re-emerge
glibc with the following command:
# emerge --ask glibc
You should receive an output similar to the following:
Calculating dependencies... done! [ebuild R ] sys-libs/glibc-2.20-r1 USE="debug*"
glibc, Valgrind should function properly.
