Unsolved -qt-xcb won't work
-
I tried to pass qt-xcb parameter to configure Qt 5.5.1 and it doesn't work.
What are the steps to make -qt-xcb available to configure, what are dependencies? I tried to find a solution, but without success.

Hi,
What errors are you currently getting ? What OS are you building on ?
-
@SGaist I am trying to build qt 5.5.1 on my Ubuntu host machine for armhf target machine.

What errors are you getting exactly ?

- Warning: Disabling pkg-config since PKG_CONFIG_LIBDIR is not set.
Warning: Disabling pkg-config since PKG_CONFIG_SYSROOT_DIR is not set.
The test for linking against libxcb failed!
Use of pkg-config is not enabled, maybe you want to pass -force-pkg-config?
You might need to install dependency packages for libxcb.
See src/plugins/platforms/xcb/README.
I don't understand this 'You might need to install dependency packages for libxcb'. Dependency packages on my virtual host machine?
If I am right I need to add path to arm libxcb lib and include folder to make it work? Or there is more to do than what I wrote? Please describe what ./configure expecting to be done for xcb before add -qt-xcb argument to it, what things need to be met?
Is it possible to compile Qt5 and run app with LinuxFB instead of using XCB? What are advantages and disadvantages?

@SGaist I solved problem with xcb! But now it tells me something like this when trying to deploy and run my app on Beaglebone Black device:
No protocol specified
QXcbConnection: Could not connect to display :0.0 -
Do you have a X server running on your board ?
In any case, you can use the other backends of Qt if you don't. You have more details about them here

@Zola I have the same problem. How did you solve this problem?
