Build issue on Noble/Jazzy

[rjoomen]

I tried building Tesseract on Ubuntu 24.04 (Noble) with ROS2 Jazzy and ran (after fixing some minor other issues) into this issue, related to qt5_wrap_cpp, and I have no idea how to fix it:

@Levi-Armstrong, do you have an idea?

[Levi-Armstrong]

Do you have a branch to look at?

[rjoomen]

No branch, just master.

Only fix needed is adding C to the languages here project(${pkg_extracted_name} VERSION ${pkg_extracted_version} LANGUAGES C CXX) in some of the makefiles, because of an issue with a dependency (issue seems related to this).

[rjoomen]

For reference, a workaround like this might be needed for the MPI::MPI_C target issue requiring the C language to be enabled. But I don't think that's related to the QT issue.

[Levi-Armstrong]

What are the next steps on fixing this?

[rjoomen]

Just today I got it all building.

• Having to add C to the languages seems to be inevitable. Issue is tesseract_urdf depends on PCL, which in turn depends on VTK, which in turn depends on MPI, which is the cause of the MPI::MPI_C include problem needing the C language.
• I solved the QT issues by switching some of the makefiles to using AUTOMOC, AUTOUIC and AUTORCC. Strange thing is that not all makefiles needed this, sometimes qt5_wrap_cpp and qt5_wrap_ui work fine. It seems some kind of path issue, maybe you can find out what causes this.

I'll submit a PR to tesseract_qt tomorrow for you to check out and we can discuss how to continue.

[rjoomen]

Submitted. The mixing of AUTOMOC/UIC/RCC and qt5wrap is not ideal, of course, either we find out why qt5wrap fails, or switch everything over to AUTO*.
