Why do I get an error similar to "undefined reference to <filename> file" when compiling MATLAB generated code with GCC?

I am using MATLAB Coder to generate C code. I want to compile this code externally, specifically using GCC and compiling the generated main.c file. but I get errors similar to "undefined reference to <filename> file".

What is the cause and how do I fix this?

This error arises because the GCC compilation command is incomplete. You need to specify all the C files that are used in the application at the command line when using GCC.

This will resolve issues with undefined references.
