build gnuradio from source on kubuntu22.04 error

[lai wieniawski]

hi, all,

I am trying to build gnuradio from source on kubuntu22.04.

I am flowing the guide:

https://wiki.gnuradio.org/index.php?title=LinuxInstall#From_Source

Where I have done

1. build UHD, and installed
   
2. build volk, and installed
   
3. build gnuradio, just clone from git, and build, donot switch to v3.9 or else.
1. using cmake to generate makefile
2. make

I face error while make:

[ 85%] Linking CXX executable display_qt
/usr/bin/ld: /lib/libqwt-qt5.so: undefined reference to `qt_version_tag@Qt_5.15'
/usr/bin/ld: /lib/libqwt-qt5.so: undefined reference to `QPushButton::hitButton(QPoint const&) const@Qt_5'
collect2: error: ld returned 1 exit status
make[2]: *** [gr-qtgui/examples/c++/CMakeFiles/display_qt.dir/build.make:135: gr-qtgui/examples/c++/display_qt] Error 1
make[1]: *** [CMakeFiles/Makefile2:3196: gr-qtgui/examples/c++/CMakeFiles/display_qt.dir/all] Error 2
make: *** [Makefile:146: all] Error 2

It seems that the version libqwt-qt5.so is not correct.

How can I fix it?

thx
