Linux build failing on Ubuntu 22.04 — Qt6 version mismatch (needs 6.4, system has 6.2.4)

[migueandres1]

Hi! I'm trying to build LibrePods on Ubuntu 22.04 following the instructions in the linux/ folder. When running cmake .. inside the build directory, the process fails with a Qt version error:

-- The CXX compiler identification is GNU 11.4.0
-- Detecting CXX compiler ABI info
-- Check for working CXX compiler: /usr/bin/c++ - skipped
-- Detecting CXX compile features
CMake Error at CMakeLists.txt:7 (find_package):
  Could not find a configuration file for package "Qt6" that is compatible
  with requested version "6.4".

  The following configuration files were considered but not accepted:
    /usr/lib/x86_64-linux-gnu/cmake/Qt6/Qt6Config.cmake, version: 6.2.4
    /lib/x86_64-linux-gnu/cmake/Qt6/Qt6Config.cmake, version: 6.2.4

Ubuntu 22.04 ships with Qt 6.2.4 in its official repositories, so there’s no straightforward way to install Qt 6.4 or newer without using external sources.

Before I go the route of manually installing Qt from the official Qt installer or building Qt from source:

My questions:

1. Is Qt ≥6.4 actually required, or would Qt 6.2 work with some minor changes to the CMakeLists?

2. If Qt 6.4+ is mandatory, would you consider adding:

   • A note in the README clarifying the required Qt version for Linux?
   • Recommended installation method for Linux distributions that ship older Qt versions?

3. Has anyone successfully built LibrePods on Ubuntu 22.04 or 20.04? If so, which Qt version did you use?

Thanks in advance — happy to test patches or help refine the Linux build instructions!
