Hello,
I have been using a win32 dll that I created using rootcint +
compiler/linker. I have been using this dll from within root for some time
now (root 3.02/07, VC++ 6.0 on win2K) - everything works fine. Here's my
question: Is it possible to use this same dll from a stand-alone win32
program?
I've tried the following:
I added the .lib file that VC++ when I built my dll to my new stand-alonge
project. The DLL exports a global variable:
R__EXTERN CAnalysis *gAn;
and I have this same line in my stand-alone program. I get the following
linker errror:
Summary.obj : error LNK2001: unresolved external symbol "public: __thiscall
CAnalysis::CAnalysis(void)" (??0CAnalysis@@QAE@XZ)
Note 1: when I use rootcint, I use a linkdef.h file that contains
#ifdef __CINT__
#pragma link off all globals;
#pragma link off all classes;
#pragma link off all functions;
#pragma link C++ class CManage;
#pragma link C++ class CAnalysis-;
.
.
.
#pragma link C++ global gAn;
#endif
Note 2: In my DLL project, I have a class CManage which contains
CAnalysis *gAn
in the implementaion file and
R__EXTERN CAnalysis *gAn;
in the .h file. When I build the DLL, I get the warning message:
LINK : warning LNK4049: locally defined symbol ""class CAnalysis * gAn"
(?gAn@@3PAVCAnalysis@@A)" imported
perhaps this is a hint...
Thanks,
Ed Oltman
