Getting "Undefined reference to" errors when building S-Function using S-Function Builder block

17 Ansichten (letzte 30 Tage)
I am creating a S-Function in simulink with the S-Function Builder block. I was initially facing "file not found" errors for some of the headers I am using in the code which got resolved after I put the entire path to the headers and source files in the libraries tab of the builder. However, I am now getting "undefined reference to" errors for all the functions that use the headers I included.

How do I resolve this? I am using Matlab 2022a

Hi Saiesh,
Refer to the "Use the Libraries Table to Specify External Code and Paths" section of the documentation - https://www.mathworks.com/help/releases/R2022a/simulink/sfg/s-function-builder-dialog-box.html and make sure that you are including the header and source files as mentioned in the documentation link. There are some examples available in the doc as well.

Hi Piyush,
It would seem I missed adding the ENTRY for the source files. With that the "undefined reference to" errors are gone but now I am getting some new errors:

The errors you are encountering are related to assembly instructions that are not recognized by the assembler being used. These specific instructions (mrs, cpsid, and cpsie) are typically used in ARM assembly language, which suggests that the code you are trying to compile is intended for an ARM architecture, but it is being compiled with a toolchain that supports a different architecture, such as x86.
Here are some steps to address this issue within Simulink:
  1. Check Target Hardware Configuration: In the Hardware Implementation pane, ensure that the Hardware board is set to the correct target hardware. If you are targeting an ARM-based board, select the appropriate option from the list.
  2. Update S-Function Builder Settings: If you are using the "S-Function Builder, ensure that the settings within the builder are configured for the correct target. Double-click on the S-Function block to open the S-Function Builder. Check any custom code or assembly code to ensure it matches the target architecture
For more information kindly refer following MathWorks documentation.
I hope this will be helpful.
