 Posted: Thu Oct 15, 2009 2:50 am Post subject: libxcb-xlib.so.0: undef ref `_xcb_unlock_io' [SOLVED] |
 |
|
Hi All,
I tried to follow the upgrade guide for libxcb.
I did
| Code: |
# emerge -1av x11-proto/xcb-proto x11-libs/libxcb
# emerge -1av x11-proto/xproto x11-proto/xextproto x11-libs/libX11 x11-libs/libXext
|
with no problems.
I also run:
| Code: |
/usr/portage/x11-libs/libxcb/files/xcb-rebuilder.sh
|
which reports a list of packages affected.
I cannot run the following code
| Code: | # emerge --oneshot \
$(for i in x11-proto/ x11-libs/libxcb x11-libs/libX11 x11-libs/libXext \
x11-libs/libX x11-libs/xcb-util x11-libs/cairo \
x11-libs/pango x11-libs/gtk\\+ \
x11-libs/qt-gui; do \
qlist -IC $i; \
done) -av
|
because a big list of blocks due to qt related packages (I'm using stable amd64 with kde4 enabled through package.keywords).
So, as decided to run revdep-rebuild to fix all the affected binaries.
Here is where it fails... anything that tries to link against libxcb-xlib.so.0, fails with undefined reference to `_xcb_unlock_io'
and undefined reference to `_xcb_lock_io'
I read many post, bugs reports, duplicated bugs, etc. with no luck.
I just don't know how to fix first libxcb-xlib.so.0 (in fact libxcb-xlib.so.0.0.0) so that all needed symbols are in place, in order to recompile the rest of my system.
Below is ldd output. Any help is appreciated.
| Code: | # ldd libxcb-xlib.so.0

Did you remove all /usr/lib/libxcb-xlib.* before running xcb-rebuilder.sh ?
Did you keyword all the qt splits ?
Do you get any output from emerge --depclean -pv ? |

I tried both, running xcb-rebuilder before and after removing lixcb-xlib.*
| Quote: |

I just have keyworded packages I needed for the 4.3 slot of kde. Up to now, I did not need
qt keyword.... Should I?
| Quote: | | Do you get any output from emerge --depclean -pv ? |
Yes, I get errors
| Code: |
Calculating dependencies... done!
* Dependencies could not be completely resolved due to
* the following required packages not being installed:
*
* <x11-libs/libxklavier-4 pulled in by:

*
* <x11-libs/libxklavier-4 pulled in by:

I don't understand why emerge --depclean is complaining. As you can see the required package is installed (in fact I reinstalled it to be sure).
Going back to the original problem I noticed that when I try revdep-rebuild , it fails in the configure part of kde3.5, complaining about a missing qt-mt library. So, I tried to re emerge qt, and I get the previously mentioned error:
| Code: | /usr/lib/libxcb-xlib.so.0: undefined reference to `_xcb_lock_io'
/usr/lib/libxcb-xlib.so.0: undefined reference to `_xcb_unlock_io' |
So, I am in cycle of errors. Please help me escape from this....
Thanks. |

The problem was solved by following the guide but avoiding the qt packages that were a problem for me (due to the blocks).
Rebuilding in the order suggested in the guided worked.
Just a piece of advice for newbies (like me) having problems during the following step :
| Code: | # emerge --oneshot \
$(for i in x11-proto/ x11-libs/libxcb x11-libs/libX11 x11-libs/libXext \
x11-libs/libX x11-libs/xcb-util x11-libs/cairo \
x11-libs/pango x11-libs/gtk\\+ \
x11-libs/qt-gui; do \
qlist -IC $i; \
done) -av |
If something fails, try emerging the base packages:
x11-proto/ x11-libs/libxcb x11-libs/libX11 x11-libs/libXext \
x11-libs/libX x11-libs/xcb-util x11-libs/cairo \
and then the rest.
thanks for all the replies. |

|

Hello, I've had a similar problem and I've been able to solve it as follows:
A)CONTEXT:
-Trying to create Unigraphics Open C api external application, compiling and linking using the ufcomp and uflink utility
-Running ubuntu64 12.04
B)PROBLEM (2):
1) When linking external applications (which you can run without UG NX running):
/usr/ugs085/ugii/libxcb-xlib.so.0: undefined reference to '_xcb_lock_io'
/usr/ugs085/ugii/libxcb-xlib.so.0: undefined reference to '_xcb_unlock_io'
2) the shared library libxcb-xlib.so is not available ubuntu anymore (libxcb1.so does still exist)
C)SOLUTION (2):
1) FAILED: Been trying pass the --as-needed flag to the GNU linker (ld) as mentioned on http://www.gentoo.org/proj/en/qa/asneeded.xml
This solution ran to dead end
2) WORKED: Backup and remove /usr/ugs085/ugii/libxcb-xlib.so.0. Now creating libxcb-xlib.so.0 as symlink to libxcb.so.1.1.0 seemed to do the trick!!
$ ln -s /usr/lib/x86_64-linux-gnu/libxcb.so.1.1.0 /usr/ugs085/ugii/libxcb-xlib.so.0
Took me a while to figure out this (rather simple) solution, hopefully it may help somebody
kind regards,
Dieter |

Great:-)
this guide helped me a lot when I compiled old but perfect twinkle (on puppylinux).
A great trick, thank you  |
