gtk3 broken with Xorg 7.6

[Jason W]

Gtk3 and it's apps are broken with Xorg 7.6.  I one day will get around to fiddling with it, but for now the gtk3 apps can just be used with Xvesa.  I am not sure I will spend too much time right now with gtk3, but I will investigate.

I've been saying that it was not my job:

you know that I do cheering for you jason

I tried building with Xorg running, made no difference.

I don't know what the issue is, either an issue with our build of Xorg (which works with everything else, also it is the latest Xorg release, so not likely the issue), or something about gtk3 or it's dependencies.

I will revisit one day in the future.

Also I did both tests, with Xvesa and Xorg 7.5, but unfortunately nothing to do

Gtk3 and it's apps are broken with Xorg 7.6.  I one day will get around to fiddling with it, but for now the gtk3 apps can just be used with Xvesa.

I don't know what the issue is, either an issue with our build of Xorg (which works with everything else, also it is the latest Xorg release, so not likely the issue), or something about gtk3 or it's dependencies.

The "guilty" is libX11.so.0.6.3 from Xlibs.tcz...Was it compiled with some custom option?

To check it, you can do (with Xorg running):
Download: http://www.x.org/releases/X11R7.6/src/everything/libX11-1.4.0.tar.bz2
Untar and cd into

Code: [Select]

tc@box:~/libX11-1.4.0$ tce-load -iw compiletc Xorg-7.6-dev libxcb-dev  #compile dependencies
tc@box:~/libX11-1.4.0$ ./configure --prefix=/usr  # /usr because libX11 from Xlibs is into /usr/lib
tc@box:~/libX11-1.4.0$ make
tc@box:~/libX11-1.4.0$ sudo make install  # overwrite libX11

Then you can run gtk3 applications without problems...(Only tested with Xorg 7.6)

[Jason W]

Thanks for the find.  I don't maintain Xorg but maybe Curaga can perhaps test a rebuild and if this is the case perhaps update Xlibs.

[AmatCoder]

Even easier: Since libx11-xcb.tcz has correct libX11.so files we can do:

Code: [Select]

tc@box:~$ tce-load -iw libx11-xcb
tc@box:~$ sudo ln -f -s /tmp/tcloop/libx11-xcb/usr/local/lib/libX11.so.6.3.0 /usr/lib/libX11.so.6.3.0
tc@box:~$ sudo ln -f -s /tmp/tcloop/libx11-xcb/usr/local/lib/libX11.so.6.3.0 /usr/lib/libX11.so.6
tc@box:~$ sudo ln -f -s /tmp/tcloop/libx11-xcb/usr/local/lib/libX11.so.6.3.0 /usr/lib/libX11.so

With this, we change symbolic links to point to libX11 from libx11-xcb instead from Xlibs.

And then we can do:

Code: [Select]

tc@box:~$ scm-load -iw l3afpad
tc@box:~$ l3afpad

[Jason W]

That is ok as a workaround but I will pm Curaga and see if he is interested in rebuilding libX11.

[curaga]

Our libX11 is 1.3.6, a standard working build. It seems like gtk3 requires xcb (which libX11 starting 1.4.0 also requires).

I'm not willing to force-add that bloat to the base (Xlibs) just yet. As I see it now, it's 5.0 material.

[curaga]

Further check to the errors is that gtk3 seems to use Xlib from multiple threads, which is not really supported without xcb. Had it directly required XCB, it would've said so configure-time and saved some time .

[AmatCoder]

Our libX11 is 1.3.6, a standard working build. It seems like gtk3 requires xcb (which libX11 starting 1.4.0 also requires).

As far as I remember, 1.3.x series also require xcb (it needs explicit ./configure --without-xcb  to avoid xcb).
Therefore all others distros works with gtk3...They have a standard libX11 build.

[curaga]

I define "requires" as in can't be built without. 1.3 series still could.

[curaga]

Response from irc.gnome.org #gtk+ is that gtk3 should still be working without xcb. I'll open a bug.

Jason and others, please comment there with any requested info etc.

It also seems 3.4.0 is out, could anyone test it?

[AmatCoder]

I understand...yes, with 1.4 xcb can not be avoided.

It also seems 3.4.0 is out, could anyone test it?

Yesterday I tried 3.4.1 -- No luck, same failure.
