Multiple definitions linking error

[zisi]

Describe the bug
When the stm32_fetch_cube() is used it gets also templates like system_stm32h7xx.c.
In case that a modified system_stm32h7xx.c is used, an error in linking is appeared related
to multiple definition of functions inside the system_stm32h7xx.c.

Sources to reproduce
https://gitlab.com/librespacefoundation/satnogs-comms/libsatnogs-comms/-/merge_requests/1/diffs
The project it is under development.

Steps to reproduce

1. Under test/CMakeLists.txt in add_executable(test ... add system_stm32h7xx.c
2. mkdir build
3. cd build
4. cmake ..
5. make

Expected behavior

Screenshots

Environment (please complete the following information):

• OS: kubuntu 20.04
• Compiler: arm-none-eabi-gcc 9.3.1
• stm32-cmake: 70a5a0a
• cmake: 3.21.0
• HAL/cube/CMSIS: stm32cubeH7 v1.9.0

Additional context
In order to fix the issue, the below code is used:

# Do not use HAL template
set(CMSIS_TEMPLATE "${PROJECT_SOURCE_DIR}/build/_deps/stm32cubeh7-src/Drivers/CMSIS/Device/ST/STM32H7xx/Source/Templates/system_stm32h7xx.c")
set(CMSIS_TEMPLATE_PATH "${PROJECT_SOURCE_DIR}/build/_deps/stm32cubeh7-src/Drivers/CMSIS/Device/ST/STM32H7xx/Source/Templates")
file(REMOVE ${CMSIS_TEMPLATE})
file(COPY "${PROJECT_SOURCE_DIR}/test/system_stm32h7xx.c"
    DESTINATION ${CMSIS_TEMPLATE_PATH}
)

Does it exists another way to not include templates?

Thank you for reporting. I think you use wrong target.
When you wish to replace some template files you must update target.

From readme:

CMSIS creates the following targets:

CMSIS::STM32:: (e.g. CMSIS::STM32::F4) - common includes, compiler flags and defines for family
CMSIS::STM32:: (e.g. CMSIS::STM32::F407xx) - common startup source for device type, depends on CMSIS::STM32::
CMSIS::STM32:: (e.g. CMSIS::STM32::F407VG) - linker script for device, depends on CMSIS::STM32::

But your code uses this:

Please have a look at #237 and #252 that have same issues with .ld files.

Hey, i use the CMSIS::STM32::H7::M7 and this commit 1dd8b73. I add to the build system system_stm32h7xx.c and startup_stm32h743vitx.s and i got errors like error: 'GPIOD' undeclared (first use in this function). I can't understand how by using the CMSIS family the building system does not include the CMSIS template like system_stm32h7xx.c.

[atsju]

Thank you for reporting.
I do not see the question ? Please clarify the question you have.

I have seen your history and you are not a noob. You can understand we maintain this repo in our free time (several hours a week). It would realy help if you could do a quality questions or clearly documented bugs. If needed please provide a code

• Github hosted
• minimalist (ideally it would be based on our examples)
• reproducing the issue

This would really help us to help you. Personally I won't look any deeper for now.

[zisi]

Hey, sorry for the delay. I prepare an example to reproduce the error. This is the example, https://github.com/zisi/stm32-cmake/tree/linking-error/examples/link-error. To reproduce it, run:

1. mkdir build
2. cd build
3. cmake ..
4. make

The output:

System:

Expected behavior
I expect to use the system_stm32h7xx.c and startup_stm32h743vitx.s that are placed inside the project and not the templates which is provided by the stm32_hal.

Thanks!!

Hello,
as already stated

CMSIS creates the following targets:

CMSIS::STM32:: (e.g. CMSIS::STM32::F4) - common includes, compiler flags and defines for family
CMSIS::STM32:: (e.g. CMSIS::STM32::F407xx) - common startup source for device type, depends on CMSIS::STM32::
CMSIS::STM32:: (e.g. CMSIS::STM32::F407VG) - linker script for device, depends on CMSIS::STM32::

So in your example it's normal that with CMSIS::STM32::H743xx::M7 you use template system and startup files.

Please add a commit to reproduce what you described here #256 (comment)

I have no time to look a this now but have you tried to understand the problem ?

/home/azisi/Documents/stm32-cmake/examples/link-error/build/_deps/stm32cubeh7-src/Drivers/CMSIS/Device/ST/STM32H7xx/Include/stm32h7xx.h:164:3: error: #error "Please select first the target STM32H7xx device used in your application (in stm32h7xx.h file)"
  164 |  #error "Please select first the target STM32H7xx device used in your application (in stm32h7xx.h file)"

first error seems to be pretty clear. You want to use your own files it's normal that you have more defines and other things to provide yourself. Please open the file and you will see that your are obviously missing a simple and mandatory define.

Thanks for the comment, i add this definition:

add_definitions(-DSTM32H743xx)

add it works.
