disabling stack smashing protector

[qleak]

One of my computers has a gentoo install with the stack smashing protector and position independent code compiled into all the libraries by default. I would like to compile wesnoth on it with the -fno-stack-protector-all or -fno-stack-protector compiler options but am not sure how to do this

I would rather compile it myself than use gentoo.. but I'm not sure where to add the -fno-stack-protector option in the config process.

Any help would be appriciated

but I'm not sure where to add the -fno-stack-protector option in the config process.

This should work:

Code: Select all

./configure CXXFLAGS=-fno-stack-protector

You will have to add a few flags because you probably want to use more of them (optimization level, architecture target, etc).

Hi,

what is wrong with

export USE="-pie" emerge wesnoth?

Albeit untested for wesnoth as of this posting, this solution works for customizing the environment for other packages. For example:

• /etc/portage/env/x11-base/x11-drm:VIDEO_CARDS=radeon
  /env/media-sound/alsa-driver:ALSA_CARDS=emu10k1
  /etc/portage/env/games-strategy/wesnoth:CFLAGS="$CFLAGS -fno-stack-protector"

1) Add the following to /etc/portage/bashrc

Code: Select all

for conf in ${PN}-${PV}-${PR} ${PN}-${PV} ${PN}; do
        if [[ -f /etc/portage/env/$CATEGORY/${conf} ]]; then
                . /etc/portage/env/$CATEGORY/${conf}
                break
        fi
done

2) Add the following to the file /etc/portage/env/games-strategy/wesnoth

Code: Select all

CFLAGS="${CFLAGS} -fno-stack-protector"

3) (Re)?Compile wesnoth

Code: Select all

emerge wesnoth
