Do you have all dependencies properly installed on your target computer ? Check running ldd on the xcb plugin[/quote]

Hi,
How I do install this dependence libxkbcommon?Regards, Niko H.

Hi,
I found how to install libxkbcommon. But now I get next error:
Linux system - locale: "English"
Cant find EGLConfig, returning null config
Unable to find an X11 visual which matches EGL config 0
QXcbConnection: XCB error: 165 (Unknown), sequence: 149, resource id: 0, major code: 149 (Unknown), minor code: 20How fix this?
Regards, Niko H.

I don't know, sorry. It looks like an issue with your Linux filesystem, not just Qt -- I think you'll have better luck if ask devs who have Raspberry Pi experience. See http://www.raspberrypi.org/phpBB3/viewtopic.php?t=35099
EDIT: You can reach people in the "Qt on Pi" project at http://qt-project.org/wiki/QtonPi-Collaborate

I'm sorry but I'm receiving the same error when I try to launch the qtcreator ide. I have just installed the qt 5 but I can't launch qtcreator for the same reason. Any ideas?
-
You need install dependencies in raspberry pi: sudo apt-get install libdrm-nouveau1a libegl1-mesa-drivers libgbm1 libopenvg1-mesa libxcb-dri2-0 libxcb-image0 libxcb-icccm4 libxcb-sync0 libxcb-keysyms1 libxcb-render-util0 libxcb-randr0
-
I've tried on installing the dependencies you have suggested installing using the apt-get command. Unfortunately that doesn't work. I'm not using raspbian at the moment, I'm trying to install the qt5 onto my ubuntu 10. I've read it is possible to develop App on ubuntu and after compilation move it to the raspbian using the cross-compiling technique.
-
Check your dependencies with command ldd program_name
-
ok... now I receive an error when I try to launch qtcreator... it seems the "libCore.so" is missing! How can I check if it is properly installed? What do I have to do to install it?
-
I have tried on installing Qt5 from git repository, I have followed the instruction guide described "here":http://qt-project.org/wiki/Building_Qt_5_from_Git and and when I make Qt using the command "make -j4 all" (I have tried both the command) I received the error bellow:
@collect2: ld returned 1 exit status
make[6]: *** [../../../../plugins/platforms/libqxcb.so] Error 1
make[6]: Leaving directory/root/opt/qt5/qtbase/src/plugins/platforms/xcb' make[5]: *** [sub-xcb-plugin-pro-all-ordered] Error 2 make[5]: Leaving directory/root/opt/qt5/qtbase/src/plugins/platforms/xcb'

-
Ok, I have installed evrything again and it has started working well. Thank you anyway.
