User:Immolo/Fortify Headers

Use the live ebuild version of sys-libs/fortify-headers

FILE /etc/portage/package.accept_keywords/fortifyfortify-headers-9999

sys-libs/fortify-headers **

Then, emerge the package:

root #emerge --ask sys-libs/fortify-headers

To use fortify-headers with Gentoo then a patch from Alpine Linux is required and a small edit to the Gentoo sys-devel/gcc ebuild.

root #mkdir -p /etc/portage/patches/sys-devel/gcc

root #cd /etc/portage/patches/sys-devel/gcc

root #wget https://git.alpinelinux.org/aports/plain/main/gcc/0016-add-fortify-headers-paths.patch

This will allow you to emerge sys-devel/gcc:

root #emerge --ask sys-devel/gcc

Note
Make sure you check that the system is using the correct version of GCC.

Finally the system needs to be rebuilt against the new headers:

root #emerge -empty-tree --exclude sys-devel/gcc @world
