Link error Visual Studio 2005 with CwclServer
« on: May 08, 2013, 12:21:26 AM »
Hello there,

I'm coding a dll that uses WCL.  When I try to get the device address and name in CwclServer , I get this weird link error from Visual Studio 2005.  I can only work in VS2005, there is no way I can upgrade to 2008 or newer.

error LNK2019: unresolved external symbol "__declspec(dllimport) public: class ATL::CStringT<unsigned short,class ATL::StrTraitATL<unsigned short,class ATL::ChTraitsCRT<unsigned short> > > __thiscall wcl::CwclCustomServerConnection::GetDeviceName(void)" (__imp_?GetDeviceName@CwclCustomServerConnection@wcl@@QAE?AV?$CStringT@GV?$StrTraitATL@GV?$ChTraitsCRT@G@ATL@@@ATL@@@ATL@@XZ) referenced in function "private: void __thiscall bluetoothCom::OnDisconnected(void *)" (?OnDisconnected@bluetoothCom@@AAEXPAX@Z)

I think the problem is related to ATLString being newer in the wcl.dll than what I have with Visual Studio 2005.

Thanks for your help,

Rene

WCL uses UNICODE. Change your project options to use UNICODE instead of MuliByte.

Hi Mike,

Even by modifying project options to use Unicode character set, I still get this error.  Do you have any idea what it could be ?

Thanks

Hi Mike,

I check my Visual Studio project and every WCL functions that returns an ATL:CStringT has a linker error like this even if the unicode character is set in the project options :

bluetoothCom.obj : error LNK2019: unresolved external symbol "__declspec(dllimport) public: class ATL::CStringT<unsigned short,class ATL::StrTraitATL<unsigned short,class ATL::ChTraitsCRT<unsigned short> > > __thiscall wcl::CwclCustomServerConnection::GetDeviceName(void)" (__imp_?GetDeviceName@CwclCustomServerConnection@wcl@@QAE?AV?$CStringT@GV?$StrTraitATL@GV?$ChTraitsCRT@G@ATL@@@ATL@@@ATL@@XZ) referenced in function "private: void __thiscall bluetoothCom::OnDisconnected(void *)" (?OnDisconnected@bluetoothCom@@AAEXPAX@Z)

bluetoothCom.obj : error LNK2019: unresolved external symbol "__declspec(dllimport) public: class ATL::CStringT<unsigned short,class ATL::StrTraitATL<unsigned short,class ATL::ChTraitsCRT<unsigned short> > > __thiscall wcl::CwclAPI::GetVersion(void)" (__imp_?GetVersion@CwclAPI@wcl@@QAE?AV?$CStringT@GV?$StrTraitATL@GV?$ChTraitsCRT@G@ATL@@@ATL@@@ATL@@XZ) referenced in function "public: void __thiscall bluetoothCom::startAPI(void)" (?startAPI@bluetoothCom@@QAEXXZ)

Received and checked

Option "Treat wchar_t as Built-in Type" must be Yes.
