debug

For valgrind to work, glibc needs debug symbols, according to its Gentoo postinst message ⇗.

Of course I don't want splitdebug on everything so I set up a Portage env instead. See the wiki for debugging ⇗ and valgrind ⇗.

/etc/portage/package.env/debugsyms

sys-libs/glibc debugsyms

/etc/portage/env/debugsyms

CFLAGS="${CFLAGS} -ggdb3"
CXXFLAGS="${CXXFLAGS} -ggdb3"
LDFLAGS="${LDFLAGS} -ggdb3"
FEATURES="${FEATURES} splitdebug -nostrip"

/etc/portage/env/installsources

FEATURES="${FEATURES} installsources"
