Qt3D 6.0.2 on Windows using MinGW 8.1.0

I am experiencing a strange problem when trying to compile Qt3D 6.0.2. I am using the MinGW 8.1.0 compiler conveniently supplied with Qt. I installed all depencies (Vulkan SDK, OpenSSL, and Perl). The compilation as such succeeded and I got all of the DLLs:
C:\Qt\6.0.2\mingw81_64\bin>dir Qt63D*.dll Volume in drive C is Windows Volume Serial Number is xxxx-xxxx Directory of C:\Qt\6.0.2\mingw81_64\bin 12.03.2021 10:17 1,370,252 Qt63DAnimation.dll 12.03.2021 09:43 1,261,206 Qt63DCore.dll 12.03.2021 10:11 1,544,460 Qt63DExtras.dll 12.03.2021 09:46 1,129,967 Qt63DInput.dll 12.03.2021 09:43 196,690 Qt63DLogic.dll 12.03.2021 10:18 610,793 Qt63DQuick.dll 12.03.2021 10:25 208,899 Qt63DQuickAnimation.dll 12.03.2021 10:23 377,370 Qt63DQuickExtras.dll 12.03.2021 10:24 183,885 Qt63DQuickInput.dll 12.03.2021 10:20 550,844 Qt63DQuickRender.dll 12.03.2021 10:22 251,139 Qt63DQuickScene2D.dll 12.03.2021 10:06 6,123,165 Qt63DRender.dll 12 File(s) 13,808,670 bytes 0 Dir(s) 533,357,686,784 bytes freeode_text
Compiling the basic shapes 3D example was also successful. Anyhow, trying to execute the program (from within QtCreator) yielded the following error message:
13:00:45: Starting C:\Qt\Examples\Qt-5.9.7\qt3d\basicshapes-cpp\release\basicshapes-cpp.exe ... Unable to find renderer plugin for opengl 13:00:46: The program has unexpectedly finished. 13:00:46: The process was ended forcefully. 13:00:46: C:\Qt\Examples\Qt-5.9.7\qt3d\basicshapes-cpp\release\basicshapes-cpp.exe crashed.
Taking a look inside the respective plugins directory reveals that the plugins where not built correctly (only .a and .prl files, but no DLLs):
C:\Qt\6.0.2\mingw81_64\plugins\renderers>dir Volume in drive C is Windows Volume Serial Number is xxxx-xxxx Directory of C:\Qt\6.0.2\mingw81_64\plugins\renderers 12.03.2021 10:55 <DIR> . 12.03.2021 10:55 <DIR> .. 12.03.2021 10:49 127,890,310 libopenglrenderer.a 12.03.2021 10:52 82,535,202 librhirenderer.a 12.03.2021 10:43 1,020 openglrenderer.prl 12.03.2021 10:49 1,094 rhirenderer.prl 4 File(s) 210,427,626 bytes 2 Dir(s) 533,356,797,952 bytes free
Am I missing something here, or might I have just come across a bug?
Many thanks in advance!
Hi and welcome to devnet,
There's something strange indeed.
It seems they have been built statically.
How did you build Qt3D ?

thanks for your reply. I built Qt3D according to the HowTo (https://wiki.qt.io/Qt6_Add-on_src_package_build_using_Conan_package_manager). More specifically I opened the appropriate Qt MinGW 8.1.0 command prompt and entered the following command line:
conan.exe install qt3d/6.0.2@qt/final --build=missing --profile=C:/Qt/Tools/Conan/profiles/qt-6.0.2-mingw81_64 -s build_type=Release -g cmake_paths -g=cmake -g deploy
I did not encounter any anomalies during the build process and it seemed to finish successfully. Might one of the dependencies cause such a strange behavior (e.g. OpenSSL)?
No that looks fine. Using static dependencies does not automatically trigger a static library creation.
It's seems to be a bug indeed.
