Hi
This is due to the improper installation of support package.
Consider performing the clean - reinstallaiton as mentioned in the following post :

I am tring to generate nad deploy code on my STM32NUCLEOF767ZI board but i met this problem "Build process stopped at compile stage. Unable to find the following link-only objects that are specified in the build information: C:\ProgramData\MATLAB\SupportPackages\R2023b\3P.instrset\cmsis_dsp.instrset\Lib\GCC\arm_cortexm7ldfdp_math\libCMSISDSP.a " and i have done the uninstallation and re-install 3 times according to the mathwork answer"Build process stopped at compile stage. Unable to find the following link-only objects that are specified in the build inform... - MATLAB Answers - MATLAB Central (mathworks.cn)"and "simulink编译报错找不到\Lib\GCC\arm_cortexm3l_math\libCMSISDSP.a - MATLAB Answers - MATLAB Central (mathworks.com)" and the problem still there. Could you pls gibe me some clue?

I have found the reason: because I am using the work computer assigned by the company, there are restrictions on the permissions, and when I use the "Get Add-ons" method to get the supportpackage in MATLAB, the installation process is successful on the surface, but in fact, the library files and other files corresponding to the supportpackage are not installed successfully, so the corresponding files cannot be found in the actual code generation phase of compilation and linking. However, the corresponding libraries of the supportpackage are not installed successfully, so the corresponding files cannot be found in the compilation and linking phases of the actual code generation.
Solution: Instead of using the one-click installer in MATLAB, use the standalone supportpackage installer:
Support Software Downloader - MATLAB & Simulink (mathworks.cn)
