Hello, I have the following declared: class RADCOMMGT_API CradComMgt { public: CradComMgt(CLog* Log=NULL); ~CradComMgt(); --- snip --- }; /***************************************/ In another file I declare this: extern CLog Log; // <- Note declaration of CLog object class radApp : public lnDaemon { public: virtual void DaemonInit(); protected: CradComMgt m_MyServer(&Log); // <- Note initialization }; /******************************************/ I get this from the compiler: g++ -o radApp -D_LINUX -L../Libraries -I../Headers radApp.cpp -lApp -lLog -lSock -lNetDataSvc -lradComMgt -lradCore In file included from radApp.cpp:16: radApp.h:24: error: invalid data member initialization radApp.h:24: error: (use `=' to initialize static data members) make: *** [radApp] Error 1 Compilation exited abnormally with code 2 at Fri Sep 12 20:04:53 I have Stroustrup's C++ reference manual and Ellis and Stroustrup's C++ Annotated reference, both of which say this should be a valid form to call the CradComMgt::CradComMgt(CLog *) constructor. What am I doing wrong here? Thanks in Advance, anw
