[SOLVED] 3.14.2-1 and CONFIG_CC_STACKPROTECTOR_STRONG

demizer · 2014-05-01 12:41:46

I'm trying to build the ZFS kernel modules for 3.14.2-1 and it's not happening. It seems 3.14.2-1 was built with gcc 4.9 which is in testing. fstack-protector-strong was added in gcc 4.9. I can't update the ZFS packages in AUR until either 3.14.2 is built with gcc 4.8, or gcc 4.9 is released to stable.

configure:12121: checking whether modules can be built
configure:12144: cp conftest.c build && make modules -C /usr/lib/modules/3.14.2-1-ARCH/build EXTRA_CFLAGS=-Werror-implicit-function-declaration   M=/build/spl-git/src/spl/build

Anyone have any ideas how to fix this? I can build the packages in testing, but not in stable.

You have already covered the main solutions. Wait for the updated tool chain to move into [core] or use [testing]. If you opt for the former, consider downgrading your kernel in the meantime.

EDIT: this is relevant: https://mailman.archlinux.org/pipermail … 36065.html

Welp, looks like we'll have to wait. Thanks!

Not real thrilled with this state of affairs. I use the broadcom-wl dkms package for wireless and am fortunate that I'm at a location today where I can plug in an Ethernet cable, as the toolchain is now broken. Somebody didn't think things through.

Same problem with rtl8723be-wifi driver. Glad to have wired lan at this moment.

Great! gcc-4.9 is in core, wifi-driver compiled just fine, all back to life.

I had the same problem. Even after updating the tool chain.

So I looked at the compilation errors and there was one regarding use of __DATE__ and __TIME__ (-Werror=date...) in line ~2043 in wl_linux.c coming from hybrid-v35_64-nodebug-pcoem-6_30_223_141.tar.gz.

I unpacked the file, changed line 2043 in wl_linux.c to not use __DATE__ and __TIME__. Repacked the tgz and updated the sha1sum in PKGBUILD. Et voila: it compiles and now I am online again.

(As I see there's now an updated aur package available on https://aur.archlinux.org/packages/broadcom-wl-dkms )
