    • Undefined reference Problem

    Posted by r2com on 2018-02-12 04:35

    Starting my c++ project normally with Projects-->New, etc.

    my main.cpp is inside src folder.

    I added some library folder to project (just copied it in a browser). That library basically contains one folder, and inside of it several folders each with .c and .h files.

    I am trying to use one function within that library func() inside main.cpp function.

    Inside main.cpp file I did include of course the main header file of the library added. However, upon compilation i still get: Undefined reference to func()

    any idea whats going on?

    The added library has .c and .h only, no object files.

    I already did try adding include directories inside project and build properties, i tried cleaning and re-building, nothing helps so far.

    quick update... i can in a crude way "fix" this problem by directly including the .c file with that function with #include statement.

    But I think it is not the right way of solving it, so what would be a better way to properly integrate it?

    Hello again r2com 😉

    Don't forget that if you add source file outside of the src folder you need to add the path of your new folder in:
    properties of your project -> C/C++ General -> Paths and Symbol -> Source Location
