LNK2019: unresolved external symbol _RfcOpenEx

57 Views

Hi,

  • i downloaded the SAP RFC SDK 7.20 unicode (Windows Server on IA32 32bit)

  • opened VisualStudio 2010

  • created new MFC dialog based project

  • added additional include directories (linked to SDK folder)

  • added additional library folders (also linked to SDK directory)

  • added librfc32u.lib;libsapucum.lib as additional dependency

  • added #include "saprfc.h"

  • put some code into the project

void CsaprfcsdkDlg::OnBnClickedButton1()

{

RFC_HANDLE rfc_handle;

RFC_ERROR_INFO_EX rfc_err_inf_ex;

rfc_handle = RfcOpenEx("",&rfc_err_inf_ex);

}

and tried to compile ... the result is an error that the external symbol RfcOpenEx is unresolved.

Anyone has an idea what i am doing wrong ?

I have a Win7 64Bit running but i also tried it on VS2003 and WinXP ... but got the same error.

Thanks for your hints.
