With CubeMX 5.4 TouchGFX 4.12.3

I create a project from scratch on 32F746DISCO.

Generate code for IAR 8.32

And I have an linking error :

Error[Li005]: no definition for "MX_FREERTOS_Init()" [referenced from .......

Is it a bug or I miss something ?

Can you post the complete error log?

MX_* are methods created by CubeMX. Can you show me your main.cpp ? You shouldn't be missing something here, in my oppinion.

MX_FREERTOS_Init() is what creates the default task handle with the touchgfx main-event loop. It would appear that, for some reason, Core/src/freertos.c is not a part of your project. Can you confirm?

Did you enable the FreeRTOS IP in CubeMX?

you shuild add "extern "c" " before MX_FREERTOS_Init().

The idea here is that the user shouldn't be required to do anything in order to achieve a compiling project - If extern "C" is missing and freertos.c is actually being compiled then we may have found an issue.

I think I found why :

You can reproduce it by validate "Generate peripheral initialization as a pair of '.c/.h' files per peripheral in generated files in project manager of STM32CubeMX project.

Is I devalidate this option, I have mo more this error

Let me know if you can reproduce it

I can reproduce the problem in CubeIDE 1.1.0 The project was created using the integrated CubeMX-tool.

I found the problem only occurs when I activate the GRAPHICS Middleware in the setup tool and the "Generate peripheral initialization as a pair of '.c/.h' files per peripheral". If either is deactivated everything seems fine.

I also tried adding "extern "c" before MX_FREERTOS_Init() but this just leads to more errors inside freertos.c.
