Hi,

I got LNK 2001: unresolved external symbol problem.


Deleting intermediate files and output files for project 'ProxyReader
- Win32 Debug'.
--------------------Configuration: ProxyReader - Win32
Debug--------------------
Compiling resources...
Compiling...
StdAfx.cpp
Compiling...
ChildView.cpp
DoConnectReader.cpp
DoGuestInformation.cpp
DoReaderScanning.cpp
MainFrm.cpp
ProxyReader.cpp
DoConnectReaderAutoProxy.cpp
Generating Code...
Linking...
DoConnectReader.obj : error LNK2001: unresolved external symbol
"public: virtual struct CRuntimeClass * __thiscall
DoConnectReader::GetRuntimeClass(void)const " (?
GetRuntimeClass(a)DoConnectReader@@UBEPAUCRuntimeClass@@XZ)


From googling, this is some sort of link library issue, etc.
What should I check with class DoConnectReader in fact ? I go through
Project -> Setting -> etc, but find it ok.

Thanks.
kenji.

Hi,

I'd say that your class has a DECLARE_DYNAMIC or DECLARE_DYNCREATE in
the class definition, yet it doesn't has its corresponding
IMPLEMENT_DYNAMIC or IMPLEMENT_DYNCREATE.

Or maybe you are calling RUNTIME_CLASS(DoConnectReader) somewhere
without specifying your class as DECLARE_DYNAMIC or DECLARE_DYNCREATE.

Regards.
