Clrdump (C ++) error LNK2019: unresolved external symbol __imp__RegisterFilter @ 8 specified in _main function

I use the makefile system with the pvcs compiler (using the Microsoft Visual C ++ compiler, 2008), and I get several link errors in the form:

error LNK2019: unresolved external symbol __imp__RegisterFilter@8 referenced in function _main

This happens DESPITE using the declaration extern "C", namely:

extern "C" int CLRDUMP_API RegisterFilter( LPCWSTR pDumpFileName, unsigned long DumpType );

In addition, in makeexe.mak the library is linked as:

$ (COMPILEBASE) \ lib \ clrdump.lib \

Honestly, I am not an expert in makefiles, and I am changing the system from Microsoft Visual C ++ 6.0 to 2008. This change may have something to do with link errors, because the system used to work before.

Any help would be really appreciated.

Thanks Advance,

Regards, Joseph

Does anyone know how to include verbose in the makefile pvcs system?

.DEF

If you decide to use __declspec (dllimport) with the .DEF file, you must modify the .DEF file to use DATA or CONSTANT to reduce the chance of the problem being encoded incorrectly:

// project.def
LIBRARY project
EXPORTS
   ulDataInDll   CONSTANT

The following table shows why:

Keyword      Emits in the import library   Exports
CONSTANT     _imp_ulDataInDll              _ulDataInDll
             _ulDataInDll                  

DATA         _imp_ulDataInDll              _ulDataInDll
