Adding libraries to Omnet++ v4.6

[Me]

Hello everybody,

I need to add my own library to Omnet++.

So I inserted the library in the following sections :

1. Project->Properties->Paths and Symbols :
1. includes
2. Libraries
3. Library Paths
2. Makemake-> Src->Options->Link-> Additional Libraries

Neverthless I still get the error of undefined symbol when I use this library.

Am I missing something
