Thanks for the help, but I finally got my mistake. As I tried to call a function written in an .cpp-file in the ReportDefault.c which is a .c-file, the linker wouldn't accept the reference.
I got around this problem by inserting a #ifdef __cplusplus extern "C" { #endif extern int Wlan_Logger(unsigned int); #ifdef __cplusplus } /* end extern "C" */ #endif in my Wlan_Logger.h like it's already done in the PerfSocket.hpp. Now the project builds without any problems...
