Details

Description: since pacman 5.0.2-2. I've recompiled xorg-server, xf86-input-libinput and xf86-video-nouveau packages using makechrootpkg and when I attempt to start X server using "startx" command ( I don't use a display manager ), There is an error in the Xorg.0.log saying undefined symbol 'exaDriverAlloc'

going back to the previous settings in makepkg.conf by removing "-fno-plt" from CFLAGS and CXXFLAGS and ",-z,now" from LDFLAGS and recompiling the xf86-video-nouveau package, X starts fine even though xorg-server is still compiled with the new pacman 5.0.2-2 changes

Additional info:
* package version(s)
1.0.15-1
* config and/or log files etc.

Steps to reproduce:

compile xorg-server and xf86-video-nouveau with pacman 5.0.2-2 default settings in makepkg.conf

CFLAGS="-march=x86-64 -mtune=generic -O2 -pipe -fstack-protector-strong -fno-plt"
CXXFLAGS="-march=x86-64 -mtune=generic -O2 -pipe -fstack-protector-strong -fno-plt"
LDFLAGS="-Wl,-O1,--sort-common,--as-needed,-z,relro,-z,now"

start X ( I used the command "startx" ) and this is where it fails to start. Look in your Xorg log file and you should see an error saying

(EE) Failed to load /usr/lib/xorg/modules/drivers/nouveau_drv.so: /usr/lib/xorg/modules/drivers/nouveau_drv.so: undefined symbol: exaDriverAlloc

recompile xf86-video-nouveau with default settings before pacman 5.0.2-2 in makepkg.conf

CFLAGS="-march=x86-64 -mtune=generic -O2 -pipe -fstack-protector-strong"
CXXFLAGS="-march=x86-64 -mtune=generic -O2 -pipe -fstack-protector-strong"
LDFLAGS="-Wl,-O1,--sort-common,--as-needed,-z,relro"

starting X works fine

So the package in Extra is fine?
Comment by Eli Schwartz (eschwartz) - Monday, 17 July 2017, 13:49 GMT
I should think so... if this is still a problem with the next version of xf86 drivers I'm sure [testing] will catch it immediately. Until then, why import trouble?
Comment by Jan de Groot (JGC) - Thursday, 20 July 2017, 11:59 GMT
X.org and drivers cannot use "-z now" in LDFLAGS. Fedora disables hardened build for Xorg and all drivers, so we should consider removing -z now from LDFLAGS when building X and drivers.

and Intel and Amdgpu is affected too:

from xorg.log:
[ 345.170] (EE) Failed to load /usr/lib/xorg/modules/drivers/intel_drv.so: /usr/lib/xorg/modules/drivers/intel_drv.so: undefined symbol: vgaHWFreeHWRec
...
[ 345.171] (EE) Failed to load /usr/lib/xorg/modules/drivers/amdgpu_drv.so: /usr/lib/xorg/modules/drivers/amdgpu_drv.so: undefined symbol: fbImageGlyphBlt

without -z,now in LDFLAGS and -fplt in CFLAGS works good.

xf86-video-intel was updated in the meanwhile, it's broken now.
Comment by Laurent Carlier (lordheavy) - Friday, 11 August 2017, 06:58 GMT
I will rebuild all xf86-video drivers with -fno-plt and -z,now filtered out and a proper comment
