Unresolved symbol problems

[SteveBrett]

AFAIK I have added a DLL correclty and yet am still gettting the following errors:

SSLTest error LNK2019: unresolved external symbol "public: int __thiscall COpenSSLApp::Hello(void)" (?Hello@COpenSSLApp@@QAEHXZ) referenced in function "public: void __thiscall CSSLTestDlg::OnBnClickedButton1(void)" (?OnBnClickedButton1@CSSLTestDlg@@QAEXXZ)

I created the Hello function as a test and can see it from the call app. However I get the errors when I compile the calling app. As a bit of a newbiew to C++ (god this is SO easy in C#) I'm kind of struggling.

The header file for COpenSSLApp is inluded and there is an entry for the location of the lib file.

Any ideas ?

Where is a body (i.e. definition or implementation) of a member function COpenSSLApp::Hello()? If your app compiled OK, this class have this member function declaration...

when i compile the calling app i get the error.

the dll compiles fine

This is a linker, not a compiler error.
Read my post again, please.

it is indeed a linker error. i have no idea what you are talking about.

i was missing the additional depencies setting in the linker options.

adding the location of the lib file fixes it.

thanks for your help.
