Yes.
The official documentation for Qt 3D Extras (https://doc.qt.io/qt-5
/qt3dextras-module.html) says:
"This module is under development and is subject to change."
We decided not to include headers for this module until it becomes
stable. We made an exception for Qt 5.14 packages because the difference
between 5.14 and the final Qt 5 API/ABI was minimal, and I backported a
patch to make sure the ABI does not change in the future. For Qt 5.12 no
such exception can be made.
I can't say that it makes the Qt 3D package unusable. You can still use
the API that is declared stable. Also you are always free to build your
own version of Qt 3D or create a PPA for it.

Bug description:
Hi,
I am a scientific software developper and I'm trying to use Qt3D on Ubuntu
20.04LTS.
I am not used to filing bugs here, sorry if its not following the standards,
any comments on this will also be appreciated.
Here is a list of the packages I installed prior to this bug.
sudo apt install qt3d5-dev
sudo apt install qt3d5-dev-tools
sudo apt install qt3d-assimpsceneimport-plugin
sudo apt install qt3d-defaultgeometryloader-plugin
sudo apt install qt3d-gltfsceneio-plugin
sudo apt install qt3d-scene2d-plugin
sudo apt install qml-module-qt3d
I also ran the command line:
sudo strip --remove-section=.note.ABI-tag
/usr/lib/x86_64-linux-gnu/libQt5Core.so.5
as per my computer science colleague request
But I am having errors left and right concerning the headers, as much
as I actually have to include in my CMakleLists.txt those lines (I
started to debug from Windows to Linux since our scientific build
machine uses this target):
#------------------------- *target*
# Note: 3D Disabled on build machine because of 3D in QT
if( ${CMAKE_SYSTEM_NAME} STREQUAL "Windows")
add_subdirectory(*target*)
set_target_properties(*target* PROPERTIES FOLDER "apps/*target*")
#Tell CMake to produce a visual studio Qt Project for integration with Qt
Vs Tools
set_target_properties(*target* PROPERTIES VS_GLOBAL_KEYWORD Qt4VSv1.0)
else
include_directories("/usr/include/x86_64-linux-gnu/qt5/Qt3DCore")
include_directories("/usr/include/x86_64-linux-gnu/qt5/Qt3DRender")
include_directories("/usr/include/x86_64-linux-gnu/qt5/Qt3DExtras") ->this
one useless
endif()
as you can see:
/usr/include/x86_64-linux-gnu/qt5$ ls
Qt3DCore Qt3DQuickRender QtDBus QtNetwork
QtPositioning QtQuick QtSerialPort QtUiTools QtWebKit
Qt3DInput Qt3DQuickScene2D QtDesigner QtOpenGL
QtPositioningQuick QtQuickParticles QtSql QtWebChannel
QtWebKitWidgets
Qt3DLogic Qt3DRender QtDesignerComponents QtOpenGLExtensions
QtPrintSupport QtQuickShapes QtSvg QtWebEngine
QtWidgets
Qt3DQuick QtConcurrent QtGui QtPacketProtocol
QtQml QtQuickTest QtTest QtWebEngineCore QtXml
Qt3DQuickInput QtCore QtHelp QtPlatformHeaders
QtQmlDebug QtQuickWidgets QtUiPlugin QtWebEngineWidgets
And this sub-package that you have does not contain the headers.
https://packages.ubuntu.com/focal/amd64/libqt53dextras5/filelist
I think I will also be submitting there I find it weird.
I will probably download Qt3D sources and temporarily link the headers
directly there but this is far from optimal for a build machine, as you might
expect.
And finaly, this packages appear when I tab on: apt install qt3d-op...
but when I run the install it cant find it. This is probably the issue that
you want to look at, as I will be going to this other package to see why the
headers are not following.
Thank you very much and I hope I followed the guidelines here are my infos:
