STM32F103C8T6 GCC problems in portmacro.h

Ymreinth · July 26, 2024, 7:16am

Hello!

I have problem with compilation FreeRTOS on STM32F103C8T6.

Command for compillator:

I don’t know how fix it problem.

I am not able to use IDE and use GCC + makefile. I try use differents makefile’s but all the time i got this problem. I took the portmacro.h and port.c from Source/portable/GCC/ARM_CM3. I use and try compile code for STM32 “Blue Pill”.

Please, help!

Do you have the definition of portFORCE_INLINE? My guess is it’s something like __attribute__((always_inline)) or even inline __attribute((always_inline)), or should be. It’s possible that the -std=gnu99 may cause the particular inline keyword used in the macro to not be recognized, so it’s treating that as an identifier, in which case it could be a dialect issue. Try changing the dialect to-std=gnu11 and see if it changes the behavior of the compiler.

From the version of portmacro.h I found in an old project (circa 2017 using the version of FreeRTOS provided in the STM32 Cube firmware library for the STM32F7 family):

#define portINLINE	__inline

#ifndef portFORCE_INLINE
	#define portFORCE_INLINE inline __attribute__(( always_inline))
#endif

It could be that you need to be using __inline instead of just inline in there, in which case you ought to define portFORCE_INLINE correctly before the header where portmacro.h is included is included.

I hope this helps you find your compilation problem.

Good afternoon and thank you for response!

I try use:

change -std=gnu99 to -std=gnu11
change portmacro.h:
it was:
#define portINLINE __inline

#ifndef portFORCE_INLINE
#define portFORCE_INLINE __forceinline
// __forceinline
#endif
it became:
#ifndef portFORCE_INLINE
#define portFORCE_INLINE inline attribute(( always_inline))
#endif
change portmacro.h:
it was:
#ifndef portFORCE_INLINE
#define portFORCE_INLINE inline attribute(( always_inline))
#endif
it became:
#ifndef portFORCE_INLINE
#define portFORCE_INLINE __inline attribute((always_inline))
// __forceinline
#endif
change -std=gnu99 to -std=gnu11 and:
it was:
#ifndef portFORCE_INLINE
#define portFORCE_INLINE inline attribute(( always_inline))
#endif
it became:
#ifndef portFORCE_INLINE
#define portFORCE_INLINE __inline attribute((always_inline))
// __forceinline
#endif

But I not found compilation problem.

I’m applying makefile:

It is old version, that i found in the Internet. URL: https

My experience is not enough for solve this problem. I try use differents makefile. If you have makefile for {stm32f103c8t6 + gcc + SPL}, please, share it.

aggarg · July 28, 2024, 6:27am

You should not need to change FreeRTOS source files. Where did you get the MakeFile from? Did you generate it using CubeMX or are you trying to write it yourself?

Ymreinth · July 29, 2024, 6:56am

Hello!

Yes, I’m trying it write myself.

I take ALL makefile’s from the internet for FreeRTOS on stm32f103, but just this makefile brought me the closest to a ready-made solution)

If you have FreeRTOS in full complectation on stm32f103c8t6, please, send me. I don’t understand Demo/CORTEX_STM32F103* - in all this demos not there is no makefile! How people it compile?)

aggarg · July 29, 2024, 9:55am

You should use CubeMX to get a starting point. Here is the Makefile project that I generated for STM32F103C8T6: FreeRTOSDemo.7z (398.2 KB)

These projects are for different IDE (such as Keil MDK, IAR) and are compiled using those IDEs.

danielglasser · July 29, 2024, 6:14pm

I’m afraid that without more information, I’m probably not going to be much help. The error message you reported in your original post is caused by the compiler thinking that the expansion of the macro portFORCE_INLINE contains an identifier of some sort.

I note that you’ve got #define portFORCE_INLINE __inline attribute((always_inline)). This should be written #define portFORCE_INLINE __inline __attribute__(( always_inline )). I don’t know for sure that the whitespace between parenthesis and the always_inline is significant, but it seems to be the common practice to surround the contents of an __attribute__(( )) qualifier with whitespace.

I am currently not working on any projects that use FreeRTOS or the STM32, so I cannot pull up the current FreeRTOS sources or any of the STM Cube firmware libraries and examples. You will find that it is sometimes hard to make an example work under the CubeMX IDE if for no other reason than that they don’t provide a CubeMX generated IO configuration file (.ioc) and you mostly have to work the IO configuration out for yourself; sometimes the documentation with the sample says what key peripheral settings are, but you must create your own .ioc file to create a usable CubeMX IDE project.

I wish you luck in solving your issues.

Ymreinth · August 5, 2024, 8:35am

I thank you for your help

Ymreinth · August 5, 2024, 8:46am

I just compile your project and it works! I am happy that the problem has been solved.

THANK YOU VERY MUCH!

I ask you to explain to me about the composition of the project. Do I understand correctly that the project that the user is writing should be in the directory?

aggarg · August 5, 2024, 9:47am

This is the project as generated by the CubeMX. I think you forgot to mention which directory you are talking about but you can create a new directory parallel to Core and Drivers to keep your code.
