multiple definition of `SystemCoreClock' (system_stm32g4xx.c included twice)

[Robert Poor]

I thought this was a manifestation of the previously reported bug Multiple definition error after STM32CubeIDE 1.9.0 update, but adding -fcommon to my compiler flags didn't fix it.

The error message is:

• multiple definition of `SystemCoreClock'
• multiple definition of `AHBPrescTable'

The root problem appears that two copies of system_stm32g4xx.c are being included in the build:

• Core/Src/system_stm32g4xx.c
• Drivers/CMSIS/Device/ST/STM32G4xx/Source/Templates/system_stm32g4xx.c

Here's an example of the full error message:

c:\st\stm32cubeide_1.9.0\stm32cubeide\plugins\com.st.stm32cube.ide.mcu.externaltools.gnu-tools-for-stm32.10.3-2021.10.win32_1.0.0.202111181127\tools\arm-none-eabi\bin\ld.exe: ./Drivers/CMSIS/Device/ST/STM32G4xx/Source/Templates/system_stm32g4xx.o:C:/Users/r/Projects/mulib-examples/test_stdbsp/nucleo_g431rb/Debug/../Drivers/CMSIS/Device/ST/STM32G4xx/Source/Templates/system_stm32g4xx.c:152: multiple definition of `SystemCoreClock'; ./Core/Src/system_stm32g4xx.o:C:/Users/r/Projects/mulib-examples/test_stdbsp/nucleo_g431rb/Debug/../Core/Src/system_stm32g4xx.c:152: first defined here

The questions:

Is this a known issue, and if so, what's a suitable workaround or proper fix?

A newcomer, what's the best way to capture the relevant environmental info in STM32CubeIDE?

Environment:

Update:

For the nonce, my workaround is to simply exclude Core/Src/system_stm32g4xx.c from the build (so it uses the file from CMSIS instead). It compiled and linked without error.

Hello @Robert Poor​ ,

First let me thank you for having reported 😊

In fact I wasn't able to reproduce any building issue from my side when starting a project based on STM32G431RBTx MCU and using the latest version of STM32CubeMX / STM32CubeIDE: the build has finished without any errors.

Could you please add more details about how did you proceed or attach your .ioc file to be able to further investigate from my side.

Your feedback will be very helpful to track the root cause of the issue.

Khouloud.

I have same kind of problem: multiple defined symbols:

SystemCoreClock

SystemD2Clock

D1CorePrescTable

SystemInit

SystemCoreClockUpdate

@CJans.1​ Files in Drivers/CMSIS/Device/ST/STM32H7xx/Source/Templates should not be included in build.

Is your makefile generated by CubeMX or CubeIDE? If not, please fix the makefile or CubeIDE project.

[Robert Poor]

Regarding the OP, note that I used CubeIDE, and I didn't specifically ask for two copies of system_stm32g4xx.c, but that's what CubeIDE generated. I had to manually exlude of of the two from the project to get it to compile.

This seems like a bug.

[Pavel A.]

@Robert Poor​ Yes, I recall the bug in CubeMX or CubeIDE that copied templates of some C files from the repository when regenerating a project. But IIRC it has been fixed long ago.

[CJans.1]

How should I remove it? Just delete it from the project browser? I do not want to delete anything that I should not delete.

[Pavel A.]

1. Exclude all these duplicate files in /Drivers/CMSIS/Device/ST/STM32H7xx/Source/Templates/ from build.
2. If this helps, you can delete the directory /Drivers/CMSIS/Device/ST/STM32H7xx/Source/Templates/ if it is copied into your project directory, then refresh the project in eclipse.
3. Consider instead of copying the ST library files into your project directory to create references to the library location (share the ST library among many projects).

@Pavel A.​ 

"But IIRC it has been fixed long ago."

That may be true, but note that I reported this problem July 10, 2022 (not that long ago). Here's the version number and build date:
