Trying to write a cpp unit test for a Cpp mapper. During compile, I get the

"
undefined reference to <function>
"

error message. The issue is that my function declaration is found (compiler knows what the arguments of the function are...) and it also finds the function implementation IF the function is implemented inline in the header file. However, it misses it when the function is implemented in the .cc file. Is this a build feature?
