[SOLVED] - LibX11-xcb.so.1 => not found
-
Hi
I just installed QT5 with QTcreator using the online installer for linux and got this error.
I looked at the many reports of this error on the forum and elsewhere but still have not found a solution.I did the ldd and found this
@linux-gate.so.1 => (0x0077c000)
libX11-xcb.so.1 => not found
libXi.so.6 => /usr/lib/libXi.so.6 (0x006d8000)
@I do not have the source nor did I compile the package. It was installed from the web. Can anyone please tell me how to solve this. I wasted a day on this already and after trying all the good advice I could find I am still no closer to using the software.

Hi and welcome to devnet,
Which version of libX11-xcb do you have on your desktop ?
Did you installed the related dev packages ?
-
Thanks for the reply. I am not sure how to tell the libX11-xcb version. Please give a hint.
I only used the linux online installer. I did install some things as they were suggested in the various posts but I cannot say that I installed any dev packages. What should I be looking for? -
You distribution package manager should tell you that.
Not knowing which distribution you are using I can't help more.
-
Ok I found the version info. It seems to be 2:1.3.2-1ubuntu3. The dev package is also installed of the same version.

You need to install libx11-xcb-dev
-
That was rather silly. I did not notice the packages were not installed. I done that and get this now.

@How do I get the right version?
-
Ok it took some scratching but I think I have it sorted. The synaptic package manager did not pick up on the fact that the gcc version was not the latest. So I had to do this:
sudo apt-get install gcc-4.7-base
sudo apt-get install libstdc++6-4.7-devand then the QTcreator loaded without a problem. Now to see if I can make it work :)
Thanks a lot for the help, it is appreciated.
-
You're welcome !
If Qt Creator can load then you are ready to do some work :)
Happy coding !

I spoke too quick, after the upgrade, I lost most of my desktop applications. I cannot even open a terminal or chrome. What applications are open is all that I have to work with. I am busy making copies of my crucial stuff and then I will have to rebuild the machine.
Linux is dangerous. -
What distribution are you on ?
Depending on the age of it and the possibility to upgrade, you should consider building Qt yourself.
-
I have a feeling that I did something stupid along the way and that I might have had something else missing or not installed correctly.
I rebuild the machine on Ubuntu 10.04 (used for Linuxcnc development) and did it this way. All is working now.@1: Download the linux 32-bit package from the QT-project website (http://qt-project.org/downloads).
NOTE: Do not use the online installer (nothing to fallback on)
2: With synaptic package manager install libx11-dev
3: then do this
sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade
4: Make the downloaded QT file executable
5: run qt-opensource-linux-x86-5.2.1.run@ -
My guess: dist-upgrade :)
Out of curiosity, can you check the Ubuntu version you have now ?
-
dist-upgrade only effected the four library files. This is the system as is now. Same as before I think.

@I think what happened is when I did the gcc upgrade I saw many removes. I do not know how I did it though and it was to late to stop. I guess I did not read the prompts well enough.

Package management is like a contract always read all the content ;)
What matters is that you have your documents and that you are up and running with Qt :)
Happy coding !
