multiple definition error when using MATLAB Coder

Hello I have problem to use the generated libraries by using Coder.

I make few static libraries by using the Coder. And the same function (inpolygon) is used in the generated libraries.

If I use the all libraries, the multiple definition error occurrs because the same function is included in the libraries.

How can I solve this problem?

Actually, when I use the MATLAB version 2020a, the previous version, there is no problem like this.

From the error shown in the screenshot you provided, both libCMAP_sector.a and libCMA_polygon.a include inpolygon.o. Additionally, both libOPGS_sector.a and libCMA_sector.a include minOrMax.o, which results in multiple definition errors during linking. To investigate further, please share a minimal reproducible sample and the exact steps to reproduce the issue.
