Missing header files for Qt3DExtras:

[Tom Wimmenhove]

Unable to build most examples contained in the qt3d5-examples (and, of course, any code that relies on Qt3DExtras). This is caused by a missing development package with headers for Qt3DExtras.

The Qt3DExtras binary library (libQt53DExtras.so) is included in the qt3d5-dev package, but all the Qt3DExtras header files are missing (Qt3DExtras/QForwardRenderer, Qt3DExtras/QPhongMaterial, etc...). This makes QT OpenGL development in Ubuntu pretty much unusable.

At first, installing mssql-mlservices-python and manually copying it's version of the Qt3DExtras headers seemed to be a work-around, but it resulted in undefined references during linking.

I would have tagged "qt3d5-examples" in the "In what package did you find this bug?", but it tells me that the package doesn't exist in ubuntu, whereas https://packages.ubuntu.com/focal/qt3d5-examples clearly lists it

Thank you for taking the time to report this bug and helping to make Ubuntu better. It seems that your bug report is not filed about a specific source package though, rather it is just filed against Ubuntu in general. It is important that bug reports be filed about source packages so that people interested in the package can find the bugs about it. You can find some hints about determining what package your bug might be about at https://wiki.ubuntu.com/Bugs/FindRightPackage. You might also ask for help in the #ubuntu-bugs irc channel on Freenode.

To change the source package that this bug is filed about visit https://bugs.launchpad.net/ubuntu/+bug/1926373/+editstatus and add the package name in the text box next to the word Package.

Launchpad has bug reports for source packages and not binary packages, I've moved this bug to be about qt3d-opensource-src.

This is fixed in Ubuntu 20.10 (Groovy) and newer versions.

Unfortunately it is not possible to fix this for 20.04 (Focal) because the change does not meet the stable update criteria.
