[SOLVED] [5.0-5944 on Linux] Dolphin Fails To Build From Source

[Sonic2kk]

Tried building a few versions of Dolphin over the past few days. I have a script which automatically clones and builds Dolphin, and noticed just yesterday that the builds were failing. Not sure what the builds were and I was too tired to take note of the errors. I just tried installing it now with version 5.0-5944 and I get the following error:

Code:

/homedir/dolphin-emu/Source/Core/DolphinQt2/MainWindow.cpp:66:42: fatal error: qpa/qplatformnativeinterface.h: No such file or directory
compilation terminated.
Source/Core/DolphinQt2/CMakeFiles/dolphin-emu-qt2.dir/build.make:374: recipe for target 'Source/Core/DolphinQt2/CMakeFiles/dolphin-emu-qt2.dir/MainWindow.cpp.o' failed
make[2]: *** [Source/Core/DolphinQt2/CMakeFiles/dolphin-emu-qt2.dir/MainWindow.cpp.o] Error 1
CMakeFiles/Makefile2:1814: recipe for target 'Source/Core/DolphinQt2/CMakeFiles/dolphin-emu-qt2.dir/all' failed
make[1]: *** [Source/Core/DolphinQt2/CMakeFiles/dolphin-emu-qt2.dir/all] Error 2
Makefile:149: recipe for target 'all' failed
make: *** [all] Error 2

Using my common sense incredible deduction skills I think it's something to do with the new Dolphin QT backend. I checked that MainWindow.cpp file and it's an include for something called "qpa/qplatformnativeinterface" (as the error would suggest). However from Googling this seems to be something that is included with QT by default. My desktop, KDE, is based on QT, so I'm not sure why I'm getting this error. It's running QT 5.9.2, and my system is fully up to date. Is there a missing dependency that I need to install perhaps? If so, what is it?

Many thanks!

What distribution do you use? KDE is a Desktop Environment, not an distribution/OS.
Did it fail recently, or for some? Did you do any package updates?
Did you install the QT private header files? It seem it is in qtbase5-private-dev (Debian).
You can also disable building the not-finished QT backend if you don't use it: Go to the build folder, run "cmake . -DENABLE_QT2=OFF", and then build manually like usual ("make -j4")

I am very aware that KDE is a desktop, I never said it was my distro ("My desktop, KDE, is based on QT"). My distro is KDE neon. I did not have the private headers installed, so using apt-get to install them worked with the package name you provided! Cheers.

No, it says "KDE neon", which is a distro.
