I don’t really understand why my project is not building on the server. “make” is working with just warnings in my VM. I executed patch.sh already.

Thanks for every help

There are no definitions of the various functions in your code.
For reference, your source directory only contains the files main.c, unit_tests.c, and test_main.c.
You can see what files are on the server by using git status or by cloning into a new location.
