Can't build gcc46-multilib

tl;dr: hit this error

xgcc: error: unrecognized option '-V'

while building gcc46-multilib.

In pacman.conf,  I activated multilib:

[multilib]
Include = /etc/pacman.d/mirrorlist

Then:

pacman -Syu
pacman -S gcc-multilib libtool-multilib base-devel multilib-devel

When I build gcc46-multilib, I hit this error:

Re: Can't build gcc46-multilib

cc1: error: unrecognized command line option '-fstack-protector-strong'

That option was added in gcc 4.9.x , so it does make sense gcc 4.6 doesn't understand it.

the last update to pacman 4.1.2-6 , changed makepkg.conf and switched from -fstack-protector to -fstack-protector-strong

CFLAGS="-march=x86-64 -mtune=generic -O2 -pipe -fstack-protector-strong --param=ssp-buffer-size=4"
CXXFLAGS="-march=x86-64 -mtune=generic -O2 -pipe -fstack-protector-strong --param=ssp-buffer-size=4"

all pre-4.9 gcc pacakges will have to be changed to work with the latest makepkg.conf.

xgcc: error: unrecognized option '-V'

No clue where that comes from, i suggest fixing the stack-protector-strong issue first.

@Lone_Wolf
Excellent sleuthing, very informative! Thanks ;-)
It helped me realize that I was still using an old ${HOME}/.makepkg.conf which doesn't yet contain the change to "-fstack-protector-strong", which would explain why the package builds fine on my box.

Re: Can't build gcc46-multilib

@ackalker, @Lone_Wolf, thank you guys for figuring out what was wrong.

Removing `-strong` fixed my issue.

I just created a .makepkg.conf file with:

CFLAGS="-march=x86-64 -mtune=generic -O2 -pipe -fstack-protector --param=ssp-buffer-size=4"
CXXFLAGS="-march=x86-64 -mtune=generic -O2 -pipe -fstack-protector --param=ssp-buffer-size=4"

Re: Can't build gcc46-multilib

I've updated the PKGBUILD so that it replaces '-fstack-protector-strong' with '-fstack-protector' in both CFLAGS and CXXFLAGS. The package now builds fine on my end, with the updated makepkg.conf.
