Unsolved Building Qt for MCU Evaluation
-
Hello everone,
I am trying to build the new Qt for MCU for an STM32F769 board but have no success to do that properly. I am using the 1.0.1-eval version for that and stucking to configure the cmake build process. Somehow the cmake is not able to find the Qt 5 package in my project. Does anybody has the same issue? Here is the cmakes output:
Running C:\Program Files\CMake\bin\cmake.exe C:/Users/martwe/Documents/FirstQtMCU "-GCodeBlocks - NMake Makefiles JOM" "-DCMAKE_BUILD_TYPE:STRING=Release" "-DCMAKE_TOOLCHAIN_FILE:INTERNAL=C:\Qt\QtMCUs\1.0.1-eval\CMake\stm32f769i-discovery.cmake" in C:\Users\martwe\AppData\Local\Temp\QtCreator-wgnjsP\qtc-cmake-qMkgucGm.

Hi and welcome to devnet,
Qt for MCU is a commercial product, you should rather contact the Qt company about matter.

Hello,
I found a workaround by myself. Actually the problem lies in the multilanguage feature, which needs some Qt tools for configuring it correctly with cmake. One Workaround is just install one binary of Qt 5.14.0 e.g. msvc2017 32 bit and assigne CMAKE_PREFIX_PATH to the location where the missing cmake file is located e.g. CMAKE_PREFIX_PATH:INTERNAL=C:\Qt\5.14.0\msvc2017\lib\cmake\Qt5. After that, cmake is then running to the end giving some warnings, but this can be ignored and all demos can be build and flashed on the target board.

Hi MMMartin,
It does look like you need to install the desktop MSVC2017 64 bit kit in order for the QT for MCU kit to compile.
It would have helped if the install instructions in getting started with Qt for MCU video would have identified what components of Qt need to be installed if only Qt for MCU is desired, and not the entire Qt software, which is a huge install. The need for this is shown in the video at 13:00.Hope this helps,
