Please read these details and reply clearly, as I have to wait for a day for reply, if something is missed out.

Updated:

undefined reference to `RevLib::GetRevLibObjectInterface()’

undefined reference to `RevLib::DeleteRevLibObjectInterface()’

Here RevLib is namespace in my shared library. GetRevLibObjectInterface() & DeleteRevLibObjectInterface() are declared in RevLibAPI.h and defined in RevLibAPI.cpp (i.e. exported functions of a dll)

Note:

Structure of My Project:

RevLibConApp is a windows application project. I have added LinuxConApp for this and compiled it.

Then added existing project RevLib (Initially a windows dll project, cross compiled with another Configuration, LinuxConfig) to the solution.

RevLibConApp is set dependent on RevLib from right_click->Project_dependencies.

compiled together with LinuxConApp config. Following is the output log:
