CMake project generation with CubeMX + CubeAI fail

Associate II


I use STM32CubeMX V6.11.1 with cmake version 3.28.1 (the one embedded in STM32CubeCLT_1.15.1) to generate a project for STM32F746G Discovery kit.

When trying the new cmake project generation feature in conjunction with CubeAI, the generated project is not building.

I get the error:

[build] Starting build
[build] Build finished with exit code -1
[cmake] -- Configuring done (1.8s)
[cmake] Build type: Debug
[cmake] CMake Error at CMakeLists.txt:64 (target_link_libraries):
[cmake] Cannot find source file:
[cmake] C:/projects/st_trials/X-CUBE-AI/App/network.c
[cmake] CMake Error at CMakeLists.txt:38 (add_executable):
[cmake] No SOURCES given to target: ai_app
[cmake] CMake Generate step failed. Build files cannot be regenerated correctly.
This issue is due to the file `cmake\stm32cubemx\CMakeLists.txt` being incorrectly generated and containing two issues:
The first one is that all over the file some path are one level too high, for example:
target_include_directories(stm32cubemx INTERFACE
    ../../../Middlewares/ST/AI/Inc #<---incorrect path
    ../../../X-CUBE-AI/App #<---incorrect path
The second one is that for some reason in `target_include_directories` the main includes are omitted (e.g. `
Once corrected, the project builds but everytime the project is regenerated, the file `cmake\stm32cubemx\CMakeLists.txt` is overwritten and the correction have to be redone. Is there a way to have the project correctly building after generation?
Thanks in advance for the response

Hello @jjaccard and welcome to the ST Community 😊.

Can you share your .ioc file so we can try to reproduce (with a description on how you did it if possible).

Best Regards.

Thanks for the welcome : )

Sure, you can find linked the .ioc file. As mentionned above, I created a project with STM32CubeMX V6.11.1 for STM32F746G Discovery kit (all default periph.). I then added X-CUBE-AI V9.0.0 with the application template and added a simple dense .tflite model. Finally I generated the code for cmake toolchain.

Then I followed your video to open and import the cmake project in vscode:

And when I try to build, the issue mentioned in my original post arise. As mentioned above, I can fix it but every time I want to change something in CubeMx and regenerate the code I have to re-fix the build system (when I update the .tflite model for example, which happens quite often).

Thanks in advance for the help.
