Hello, I got some procompiled .o files (Atollic studio) for my CubeIDE Project. In which way can i include this files. Best regards Stephan

You compile your code with header files that contain the definitions of the global symbols of the object files, and then link the object files with the program.

You can use the ranlib tool to create a library. It is usually part of the gcc toolchain.

And yes, you would need the headers for the compiler.
