I always get this or similar errors when trying to install gcc (-hardened):

there's a problem in step 2.5:

I only get:

Quote:

gcc-config -l
[1] i686-pc-linux-gnu-3.4.6
[2] i686-pc-linux-gnu-3.4.6-hardenednopie
[3] i686-pc-linux-gnu-3.4.6-hardenednopiessp
[4] i686-pc-linux-gnu-3.4.6-hardenednossp
[5] i686-pc-linux-gnu-3.4.6-vanilla
[6] i686-pc-linux-gnu-4.1.2 *

gcc 4.1.2 is supposed to offer a hardened profile, which is disabled by ebuild

update:

now using hardened toolchain overlay ...

update2:
by using kevin quinn's hardened overlay files for gcc it worked pretty easily:
http://overlays.gentoo.org/svn/dev/kevquinn/hardened/toolchain/branches/

switching from a default to a hardened profile + using the hardened gcc 3.4.6 compiler of a hardened box also worked with that ebuild (4.1.2-r1)

thanks for that great work, now that only needs to be merged to the official portage tree (when it's ready (TM)

)...
