If so, looks as if current git versions of the intel driver will not be
usable with gcc-5.1.
But I only tried the git version to see if the segfault had already been
fixed.
Unfortunately, we are on the bleeding edge here, along with Arch.
Arch uses post-release GCC snapshots. So they already include all (most) patches
>from gcc 5 branch.
For me the patch applies cleanly and the build is OK. I'm running tests now.
I need to update some packages in LFS anyway so I'll add this patch and
start a new build on a system that uses the intel driver to see if that
fixes things up. Since I'll need to build X on the new system, I may not
get to that until tomorrow.
I intend to continue with the released version of the driver, to see
if I can get a backtrace when I build an unstripped system.
If not, or if that gets blamed on gcc, it will be useful to know if
the git version will build with a patched version of gcc.
I didn't do a git version, but I did build Xorg today with yesterday's LFS svn.
I built the following drivers in this order:
libvdpau-1.1
libevdev-1.4.2
xf86-input-evdev-2.9.2
xf86-input-synaptics
xf86-video-intel-2.99.917
libva-1.5.1
libva-intel-driver-1.5.1
libvdpau-va-gl-0.3.4
My video is:
00:02.0 VGA compatible controller: Intel Corporation 4th Gen Core Processor
Integrated Graphics Controller (rev 06) (prog-if 00 [VGA controller])
Subsystem: Toshiba America Info Systems 4th Gen Core Processor Integrated
Graphics Controller
model name : Intel(R) Core(TM) i7-4700MQ CPU @ 2.40GHz
With the patch in gcc, everything built fine, but with the default sna
acceleration I *did* get a seg fault.
Adding the /etc/X11/xorg.conf.d/20-intel.conf file as in the current book did
allow Xorg to come up.
One other thing. The first time I ran xorg, I had some driver failures. It was
easily fixed by running ldconfig, but we might want to consider adding that to
the instructions to run startx at the beginning of Xorg-7.7 Testing and
Configuration.
