Summary: An Open Source memory debugger for GNU/Linux.
Keychain 2.8.2 ReleasedKeychain 2.8.2, a maintenance and bug fix release, is now available.
Unfork Tree is Live!The "unfork" tree is now merged into the main Funtoo Linux tree, and Funtoo Linux is now using shards for core packages, x11 (including media libraries), KDE, GNOME, python and perl.
OpenSSH 7 Disables DSA Keys By DefaultPlease be aware of this important change to avoid getting locked out of your Funtoo server.
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.
