File lprodump missing after installing Qt6 and using LinguistTools in CMake

Question

I've encountered an issue while setting up a Qt6 project with CMake on Linux Mint.
Despite successful installation of Qt6 and its components, I'm facing a problem with Qt6LinguistTools. Specifically, when I use find_package(Qt6 REQUIRED LinguistTools) in my CMakeLists.txt, CMake generates an error indicating that the lprodump file is missing.

Here's the error message I receive:

CMake Error at /usr/lib/x86_64-linux-gnu/cmake/Qt6LinguistTools/Qt6LinguistToolsTargets.cmake:131 (message):
  The imported target "Qt6::lprodump" references the file

     "/usr/lib/qt6/libexec/lprodump"

  but this file does not exist.  Possible reasons include:

  * The file was deleted, renamed, or moved to another location.

  * An install or uninstall procedure did not complete successfully.

  * The installation package was faulty and contained

     "/usr/lib/x86_64-linux-gnu/cmake/Qt6LinguistTools/Qt6LinguistToolsTargets.cmake"

  but not all the files it references.

I've tried reinstalling Qt6 and its components, but the file still does not appear in the expected directory.

Is there a specific package in Linux Mint (Ubuntu) that contains the lprodump file for Qt6, or is there a known workaround for this issue?

Everything was working correctly before, and I haven't knowingly changed anything in my setup that would cause this problem.

Answer 1

To resolve the issue with the missing lprodump file, install the qt6-tools-dev-tools.

Use the following command:

sudo apt install qt6-tools-dev-tools

This should address the missing file problem.

To verify that the file is indeed in the package, you can use the dpkg utility:

dpkg -L qt6-tools-dev-tools

Output:

As seen, the file is presented in the list.
