STM32CubeIDE 1.13.0 problem

[Phillip Wolstencroft]

I have just updated the IDE from 1.12.1 and updated my project as requested but I have encountered an issue when compiling.

I get 3 errors on previously compiling  source code. as follows

Can you help with what might be the problem?

Hi everybody,

I have the same problem working on an old workspace with STM32L4 fw package 1.11.0. The trick suggested by Peter works for me, but I would like to know if it depends on the old fw package or there is something else. I have regenerated the code from CubeMX and I have added my sources keeping the old version of HAL, LL and CMSIS libraries. I'm also using FreeRTOS version 10.1.1. So, doing this, only the project files have been updated (.cproject and .project files), but the problem is still there. Does anyone help me to figure it out? Which library has a reference to (or use) these "undeclared functions"?

Thanks in advance.

Same Problem here. Solved as follows:

- create a new project with 1.13.1
- grab the files syscalls.c and sysmem.c from Core/Src
- add those files to your existing project

You're done

Thank you! Now I get it, I didn't notice that those functions are defined in syscall.c. There were no sysmem.c and syscall.c in my old workspace.

So, I still have problems with the GCC from STM32CubeIDE version 1.13.2, and no workaround is working for me.

So fare:

• My project is compiling perfectly fine with CMake and GCC from IDE version 1.12.1
• When changing to GCC from IDE 1.13.2 (and changing only that), I have link error.
• After copying sysmem.c and syscalls.c from a new project generated with IDE 1.13.2, I still have errors:

Is there any other workaround to use?

Do ST plan to release a corrected version of STM32CubeIDE version 13? First mentions of the problems are more than 3 month old! Or should I go back to version 1.12 and never update any more?

Hi ANauz.1

Those issues are not a bug or a defect from the latest STM32CubeIDE. This is a generic issue of gcc libraries causing a warning at linking stage.

“warning: _close is not implemented and will always fail” is not a linker error but a warning placed inside the recent implementation of libnosys as part of gcc libraries. This libnosys provides dummy system calls (read/write/close/lseek) and kindly warns the user during linking stage that any attempt to use those system calls will fail (as this is a dummy implementation). As explained, this is ‘just’ a warning, and the linker is able to generate a proper ELF file. As long as your application does not use read/write/close/lseek (which should be the case for a bare metal application), your application will run properly.

 

So,

• the first option is to ignore those warnings.
• A second option is to patch the libnosys.a to get rid of those warnings (see stackoverflow discussion below).
• A third option is to provide your ‘own’ implementation of the system calls. You can simply generate a new STM32CubeIDE project with STM32CubeMX and reuse the syscalls.c and sysmem.c files in your initial project.
• and all other options suggested in this thread (use older toolchain, etc.).

 

Regarding the multiple definition linker error in your application, this is likely caused by a duplicated object file having the system calls symbols or a duplicated syscall source file: clean your build directory, make sure your source files do not contains several definitions of those system calls. The linker map file should help to find the root cause of the duplicate symbol definition (or use linker verbose mode).

1.) find your old version of syscalls.c

2.) find the #if 0 and matching #endif

3.) remove them.

4.) enjoy!

This problem has been resolved with the latest update from STM32 CubeIDE. Just update your IDE and make sure you are using the following Toolchain: 11.3 rel 1.
