Undefined reference Problem

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

ah right, yeah that seemed to work now, thanks!
