Cube Hal cmsis_os bug, missing #define __CORTEX_M

Using STM32Cube_FW_F4_V1.9.0 and setup a project with CubeMX 4.11 and using Freertos.

I usually build with -Wundef. When compiling cmsis_os.c, I earn a:

core_cmFunc.h:501:12: warning: ''__CORTEX_M'' is not defined

http://www.openstm32.org/-Wundef

This is, because `#include ''core_cmFunc.h''` obvouisly needs a e.g. `#include …` before so that the preprocessor symbol `__CORTEX_M` became defined. This appears for every source which tries to include cmsis_os.h (e.g. the cubemx generated freertos.c).

I'd checked the suggestion of thomas.004 ''changing the #include order'', but in my project this approach won't fix the warning because my FreeRTOSConfig.h has no `#include ''stm32...h''`.

I further confirm, that this issue still exist in F4 V1.10.0. Could this please fixed by ST Cube Hal developers in future releases?

__CORTEX_M

is defined in core_cm4.h

maybe a solution is to swap the following includes in cmsis_os.h

//#include ''core_cmFunc.h''

#include

''FreeRTOS.h''

#include

''core_cmFunc.h''

FreeRTOS.h includes

FreeRTOSConfig.h << stm32f4xx_hal_conf.h << stm32f4xx_hal_XXX.h

<< stm32f4xx_hal_def.h << stm32f4xx.h << stm32f4??xx

<< core_cm4.h

For me, I had to add the following include in cmsis_os.h:

#include ''stm32f4xx.h''

before

#include ''core_cmFunc.h''

How ever it gets overwritten on every re-generation from ST32CubeMX. To solve this temporarily, you can edit the template used by STM32CubeMX in cmsis_os.h in <PATH TO YOUR STM32CUBEMX-REPOSITORY>\STM32Cube_FW_F4_V1.0\Middlewares\Third_Party\FreeRTOS\Source\CMSIS_RTOS\
