Hi, I'm trying to compile Qt 5.15.10 and Qt Creator 7.0.2 from source on CentOS 7.9.2009, kernel version 3.10.0-1160.95.1.el7.x86_64.
I think I successfully built and installed Qt & Qt Creator, however I couldn't launch Qt Creator. The error is always:
qt.qpa.plugin: Could not find the Qt platform plugin "xcb" in ""This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.Available platform plugins are: linuxfb, minimal, offscreen, vnc, wayland, webgl.I downloaded the source code from Qt's official archives, and this is what I did:
First, I installed necessary dependencies:
sudo yum install epel-release centos-release-scl
sudo yum update
sudo yum install python3 cmake3 devtoolset-9-gcc devtoolset-9-gcc-c++
And switched to GCC 9:
source /opt/rh/devtoolset-9/enable(When installing CentOS 7, I already selected the Develepment Tools so most other building tools were already present.)
Then I
cd'd to Qt's source directory and ran:./configure(I chose the Open Source license)
gmake
sudo gmake installNo task-stopping errors occurred, so I went on building Qt Creator. I
cd'd into Qt Creator's source directory and ran:export PATH=/usr/local/Qt-5.15.10/bin:$PATH
(Becausegmake installinstalled Qt to/usr/local/Qt-5.15.10/)
qmake -r
cmake3 -DCMAKE_BUILD_TYPE=Release "-DCMAKE_PREFIX_PATH=/usr/local/Qt-5.15.10/" /home/me/qt-creator-opensource-src-7.0.2/
cmake3 --build .
sudo cmake3 --install . --prefix /usr/bin/qtcreator_install
(I opted to install the binaries to/usr/bin/qtcreator_install)
export PATH=/usr/bin/qtcreator_install/bin:$PATHAll went well until I tried to actually run Qt Creator:
[me@localhost qtcreator_build]$ export PATH=/usr/bin/qtcreator_install/bin:$PATH[me@localhost qtcreator_build]$ qtcreator
qtcreator: error while loading shared libraries: libQt5Qml.so.5: cannot open shared object file: No such file or directoryI thought this was about the dependecies, so I installed again with them bundled:
[me@localhost qtcreator_build]$ sudo cmake3 --install . --prefix /usr/bin/qtcreator_install --component Dependencies
-- Install configuration: "Release"
'/usr/bin/python3.6' '/home/me/qt-creator-opensource-src-7.0.2/scripts/deployqt.py' '/usr/bin/qtcreator_install/bin/qtcreator' '/usr/local/Qt-5.15.10/bin/qmake'
Cannot find required binary 'chrpath'.Naturally I installed chrpath:
sudo yum install chrpathAnd did it again:
sudo cmake3 --install . --prefix /usr/bin/qtcreator_install --component DependenciesThis time the installation succeeded, but I ran into the issue in the topic:
[me@localhost qtcreator_build]$ qtcreator
qt.qpa.plugin: Could not find the Qt platform plugin "xcb" in ""
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.
Available platform plugins are: linuxfb, minimal, offscreen, vnc, wayland, webgl.
Aborted (core dumped)Now I'm stuck with this xcb problem. I checked this
link in the forums and followed suit by running:
sudo yum install libxcb libxcb-devel xcb-util xcb-util-devel
But installing those packages didn't resolve the issue.Running Qt Creator directly from my build directory also returns the same result:
[me@localhost qtcreator_build]$ ./bin/qtcreator

This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Aborted (core dumped)Interestingly, I tried to Qt Creator again, this time without prefixes, and got the following:

[sudo] password for me:

Cannot find Qt Creator binary.Has anybody built Qt Creator from source on CentOS 7? Can anyone please offer guidance on why I'm running into this
xcbissue with theqt.qpa.pluginwhen launching Qt Creator? Thanks! -
Hi and welcome to devnet,
Start Qt Creator with the QT_DEBUG_PLUGINS environment variable set to 1 to see exactly what fails.

It is not enough to install these packages. You need to rebuild Qt so, that xcb plug-in is built. Check output of the configure command to see whether xcb was activated or not.

xcb-util-wm-devel, then rebuilt Qt and Qt Creator repeating the same steps, but the issue persists, I still couldn't get Qt creator running.The output of Qt's configuration is:

@jsulm Hi, thanks for replying. In addition to those packages I also installed
xcb-util-wm-devel, then rebuilt Qt and Qt Creator repeating the same steps, but the issue persists, I still couldn't get Qt creator running.The output of Qt's configuration is:

From the looks of it, your custom built Qt does not have the xcb plugin. You are likely missing one or more of the dependencies required to build it.

Based on the configuration output of
./configureprior to building Qt, all things related toxcbseem to be fine.The debug output of Qt Creator's launching also shows that
QFactoryLoader::QFactoryLoader()was able to get keys by looking at/usr/local/Qt-5.15.10/plugins/platforms/.According to the debug output, my issue occurs when
QFactoryLoader::QFactoryLoader()looks at/home/lbh/qt-creator-opensource-src-7.0.2/bin/platforms, which is where I built Qt Creator. Does this suggest that the problem is with Qt Creator itself? -

libqxcb.sois not generated when building Qt. So far all attempts to build that plugin have failed. Any suggestions? -
