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.

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.

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:

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