Static build qt. Getting error because of xcb

BrMisha

Hi!
I'm trying to build static qt on Ubuntu. I built using this:

./configure -prefix /home/misha/Qt5_14_2_static -release -opensource -confirm-license -static -no-glib -no-pulseaudio -no-alsa -opengl desktop -nomake examples -nomake tests

Then made simple gui project, but after start i got error:

qt.qpa.plugin could not find the qt platform plugin "xcb" in ""

Then i tried to build qt with xcb:

./configure -prefix /home/misha/Qt5_14_2_static -release -opensource -confirm-license -static -no-glib -no-pulseaudio -no-alsa -opengl desktop -nomake examples -nomake tests -qt-xcb

But getting this:

ERROR: Feature 'xcb' was enabled, but the pre-condition 'features.thread && features.xkbcommon && libs.xcb' failed.

I tried to set direct link to xcb after "-qt-xcb" but it still doesn't want to configure.
Help me, please)))

Hi,

You need the libxkbcommon development package for your distribution.

BrMisha

No, i already installed))

SGaist

Then check the test logs to see exactly what failed.

BrMisha

Thanks, there is really something strange)))

loaded result for library config.qtbase_gui.libraries.xkbcommon

But /usr/include/xkbcommon/xkbcommon.h is exist. I can include it from qt creator. But why ./configure doesn't see that?

A very similar discussion is taking place at: https://forum.qt.io/topic/114784/definitive-guide-to-building-source-from-downloaded-run-file/29

No solution posted yet, though.

SGaist

Silly question but did you check that you have that file in your system ?

BrMisha

@SGaist Of course i checked))

SGaist

Did you install the package after calling configure ?
If so, did you call configure from a clean state ?

BrMisha

I have re-unziped sources and tried again. And... configure done)))
Thank you very much))))

@BrMisha - so is "configure -qt-xcb" working for you now?

Tom asso

@SGaist - how to make a "clean slate" before running configure again?

Tom asso

See my note in this thread - I'm able to configure and build 5.14.0, but experience the same problem as @BrMisha with 5.14.2.

BrMisha

@Tom-asso yes))

BrMisha

I can share my build package if somebody need

SGaist

The easiest is to do out of source builds so you can easily nuke the build folder to start anew.

Tom asso

@BrMisha - I'm trying to build qt-everywhere-src-5.14.2 on ubuntu, having very similar problem with xcb that you report, i.e. "./configure -qt-xcb" gives errors. Are you also building qt-everywhere-src-5.14.2? How exactly did you overcome your problem and successfully build?
Thanks!

BrMisha

@Tom-asso At first i installed libxkbcommon-dev then
@BrMisha said in Static build qt. Getting error because of xcb:
