xorg-x11 crashes when compiled with gcc 3.4

darkphader · Veteran Joined: 09 May 2002 Posts: 1217 Location: Motown

If I compile xorg-x11 with gcc-3.3 it works fine but when compiled with gcc-3.4 it always crashes after starting up. When trying to start kde I receive "Can't contact kdeinit!", but it's not just kde, none of the window managers will stay running if I compile xorg-x11 with gcc-3.4.
Wondering if anyone else is seeing this problem and if there's a cure.

Thanks.

Chris

I have not experienced this problem yet. What CFLAGS are you using? Did you try recompiling everything with 3.4?

I have xorg compiled with gcc-3.4.1 and glibc-2.3.4. I don't remember exectly the problems I had, but after I emerged gcc, I emerged new glibc, then ran all the update scripts and re-emerged new gcc and glibc again... :roll:

Though it's not a nice way to do things, but it worked. :oops:

On my bootstrapped-with-3.4.1 system, xorg-x11 is extremely unstable, especially using the nvidia driver. It consistently crashes when I try to start KDE or Gaim. Fluxbox works okay, though. With the nv driver, it seems a little more stable, but again always crashes if I try to start Kolf (for example).

My CFLAGS are very conservative.

No problems here 3.4.0.

CFLAGS="-march=pentium3 -O2 -pipe -ffast-math -fomit-frame-pointer -mfpmath=387,sse -ftracer -fforce-addr"

Kernel 2.6.3 headers

I also have stability problems in X with nvidia using GCC 3.4.x. At first I thought it was a dependency problem so I re-emerged everything but it didn't work. I just started from scratch today, and I find that most desktop environments crash except fluxbox. Fluxbox is pretty minimal so I think it is some type of dependency problem. Reading the logs only tells me that xorg is causing some IO error, and it isn't too descriptive. I hope someone can find the issue here.

I'll see if I can just recompile xorg-x11 with 3.3.3, and see if the staiblity problems go away.

I wouldn't blame it on nvidia...

I just compiled my xorg-x11 with gcc 3.3.3, and left the rest of my system as 3.4 compiled. Everything runs smoothly now. I'd think xorg-x11 is the culprit.

I have my complete system compiled with gcc-3.4.0 and have no problems with xorg and kde-3.3.0-beta1, using Matrox...

Just to add to the topic, I'm having similiar problems. Using the nvidia drivers, xorg crashes at some point loading my desktop (I use gnome). However, if I login in as root it loads just fine but it crashes if I start trying to do sometime, like clicking on an object. I switched over to the nv drivers and I haven't had any probs yet.

I'm running xorg-x11-6.7.0-r2, nvidia 6106 drivers, and gcc 3.4.1.

xfree was running just perfectly fine under that setup.

PS: Incase anyone wants/needs to know, my entire system is compiled with 3.4.1.

So do we post a bug report for the nvidia drivers?

No, I don't think it's anything to do with the nvidia drivers. The common factor is something else. Can all those who are having stability problems please post the output of "emerge info"?

Why not, rob? Can you (or someone you know) run xorg/nvidia/gcc34 without problems?

Here's mine:

Are everyone with problems using -march=pentium4? How about trying to compile xorg with CFLAGS="", just to see if CFLAGS are related to the problem.

I don't believe it. I just did:

pkdawson · Posted: Mon Jul 19, 2004 1:07 am Post subject:

My results so far:

CFLAGS="-O2 -march=pentium4 -fomit-frame-pointer -pipe"
USE="+mmx +sse"
CRASH

CFLAGS="-march=pentium4"
USE="-mmx -sse"
OK

CFLAGS="-march=pentium4"
USE="+mmx +sse"
OK

CFLAGS="-O2 -march=pentium4 -fomit-frame-pointer -pipe"
USE="-mmx -sse"
CRASH

CFLAGS="-O2 -march=pentium4"
USE="-mmx -sse"
CRASH

CFLAGS="-O2 -march=pentium3"
USE="-mmx -sse"
OK

CFLAGS="-O2 -march=pentium3 -fomit-frame-pointer -pipe"
USE="+mmx +sse"
OK

Conclusion(s) thus far:
- pentium4 and O2 don't mix

I'll keep updating this post until I have enough data to suggest a solution.

well, i got stability probs too with xorg, gcc3.4.x, nvidia and -march=pentium4 -O2 -fomit-frame-pointer -pipe.
One example is when i start gcalctool X instantly crashes.
The problem was gone when i changed march to pentium3.
Nevertheless now its still a bit unstable, at least since im using the latest 6xxx nvidia drivers.. X tends to hang with 100% cpu usage when i play videos with mplayer quite often for example, though it happened while browsing with firefox too..
To finally get rid of this i changed the X driver to nv and got a perfectly stable system again now. (i don't need 3d most of the time, though yeah it should work..)
as it is more stable with march=pentium3 and worked with gcc3.3.x it sounds like a gcc3.4.x problem, either a bug or compatibility issue :/
