Issue after updating to STM32CubeIDE 1.13.2

[crwper]

After updating to STM32CubeIDE 1.13.2, and updating my workspace, I'm suddenly getting warnings when compiling the STM32_WPAN SHCI library, followed by a handful of linker errors. The warnings are all in `shci.c` and look like this:

Project/Middlewares/ST/STM32_WPAN/interface/patterns/ble_thread/shci/shci.c: In function 'SHCI_C2_FUS_GetState':
Project/Middlewares/ST/STM32_WPAN/interface/patterns/ble_thread/shci/shci.c:57:98: warning: array subscript 'TL_CcEvt_t[0]' is partly outside array bounds of 'uint8_t[16]' {aka 'unsigned char[16]'} [-Warray-bounds]
   57 |     *p_error_code = (SHCI_FUS_GetState_ErrorCode_t)(((TL_CcEvt_t*)(p_rsp->evtserial.evt.payload))->payload[1]);
      |                                                                                                  ^~

      |           ^~~~~~~~~~~~

 The linker errors look like this:

Any idea what's going on here? As far as I know, I've made no changes to the project since it last compiled without issues.

Hello @crwper ,

I think you have the same issue shared in this post. 

Please try to use this workaround:

Go to Windows > Preferences
Open the tab Error Parsers into C/C++ > Build > Settings
Select GNU Linker Error Parser, double click on the pattern for the 1st severity Ignore
Changer :
(.*?):?(\(\.[^\s+]+\+.*\))?:\s*(In function [`'"](.*)['"]:)
to :
(.*?):?(\(\.[^\s+]+\+.*\))?:\s*([Ii]n function [`'"](.*)['"]:)

Please let me know if the issue is solved.

Thank you.

Kaouthar.

This now seems to ignore the linker errors, but I still get warnings for the following items:

• The "partly outside array bounds" issue mentioned above
• The "not implemented an will always fail" issue mentioned above

As this code belongs to a bootloader which cannot be modified in the field, I want to be absolutely certain that these warnings won't affect function. Can you please explain to me in detail why these warnings started showing up when I updated the workspace, what they are indicating, and why you feel they can safely be ignored?

Thank you!

Hello @crwper ,

Thank you for your sharing this update.

The problem that is causing the failed build was described in CDT (https://github.com/eclipse-cdt/cdt/commit/1b2472faff2028f0323ad5c5eb85565f81b89053).

For more information about these warnings and how fixed them, I advise you to check this post and precisely @Peter BENSCH answer. 

I hope this help you.
