Error LNK2019 when using GetFileVersionInfoSize()

Question

I just included this bit in my already working code, but I am getting an LNK2019 error. I'll paste the error after pasting the code.

The Class CAboutDlg has:

public:

    CStatic m_VersionInfoCtrl;

   virtual BOOL OnInitDialog();

};

The Function itself:

BOOL CAboutDlg::OnInitDialog()

{

   CDialog::OnInitDialog();

   CString inFileName = AfxGetApp()->m_pszExeName;

   inFileName += ".exe";

   void * theVersionInfo;

   void * theFixedInfo;

   unsigned long aVersionInfoSize = GetFileVersionInfoSize ( inFileName , &aVersionInfoSize);

   CString returnString;

   if (aVersionInfoSize)

   {

   theVersionInfo = new char [aVersionInfoSize];

   GetFileVersionInfo ( inFileName, 0 , aVersionInfoSize, theVersionInfo) ;

   unsigned int aSize = 0;

   VerQueryValue( theVersionInfo , "\\" , &theFixedInfo , &aSize);

   if (theFixedInfo)

   {

   VS_FIXEDFILEINFO * aInfo = (VS_FIXEDFILEINFO *) theFixedInfo;

   DWORD dwMajorVersionMsb = HIWORD( aInfo->dwFileVersionMS );

   DWORD dwMajorVersionLsb = LOWORD( aInfo->dwFileVersionMS ); 

   DWORD dwMinorVersionMsb = HIWORD( aInfo->dwFileVersionLS );

   DWORD dwMinorVersionLsb = LOWORD( aInfo->dwFileVersionLS ); 



  returnString.Format("Version %d . %d . %d. %d",dwMajorVersionMsb,dwMajorVersionLsb,dwMinorVersionMsb,dwMinorVersionLsb);

  //memcpy(sVer,returnString.GetBuffer(),returnString.GetLength()+1);

  }

delete theVersionInfo;

   }

   m_VersionInfoCtrl.SetWindowText(returnString);

   return TRUE;  // return TRUE unless you set the focus to a control

   // EXCEPTION: OCX Property Pages should return FALSE

}

....

Its giving me the following three errors:

1.RangemasterGenerator error LNK2019: unresolved external symbol _VerQueryValueA@16 referenced in function "public: virtual int __thiscall CAboutDlg::OnInitDialog(void)" (?OnInitDialog@CAboutDlg@@UAEHXZ)

2.RangemasterGenerator error LNK2019: unresolved external symbol _GetFileVersionInfoA@16 referenced in function "public: virtual int __thiscall CAboutDlg::OnInitDialog(void)" (?OnInitDialog@CAboutDlg@@UAEHXZ)
3.RangemasterGenerator error LNK2019: unresolved external symbol _GetFileVersionInfoSizeA@8 referenced in function "public: virtual int __thiscall CAboutDlg::OnInitDialog(void)" (?OnInitDialog@CAboutDlg@@UAEHXZ)

... I am not able to understand what the problem is. Can anyone help please. Thanks.

You need to link against the library that contains the two functions VerQueryValue and GetFileVersionInfo - the linker doesn't know by default where to find them.

A quick search for the two functions on MSDN suggests that they're both in the system library version.dll and the library you want to link against is version.lib. Just add that to the library list in the linker properties.

I have added version.lib in my header file as: #pragma comment(lib,"Version.lib") How do I add the .dll file? – Neophile Aug 11 '11 at 15:18
Are you sure that header file gets compiled? Specially the line that has given `#pragma` ? – Ajay Aug 11 '11 at 15:22
line 11. Its after declaring my header files. – Neophile Aug 11 '11 at 15:24
Cheers, I got it. Thanks Guys. – Neophile Aug 11 '11 at 15:36

You don't have to add the .dll file - the .lib is an import library that ensures that the loader pulls in the correct .dll at runtime. – Timo Geusch Aug 11 '11 at 18:49

This answer is helpful because the current version of MSDN says to include `mincore.lib` which does not contain the symbols. Version.lib is still needed. – Nathan Kidd Apr 24 '18 at 00:19
I just noticed that too "Library Mincore.lib" not version.lib, which actually fixed it. – stu Aug 09 '18 at 14:21

The functions GetFileVersionInfo and GetFileVersionInfoSize are defined in Version.dll and Version.lib so make sure, you are liking to the appropriate libraries.

Actually a CStatic is a specific kind of MFC control, not a static member. See here: http://msdn.microsoft.com/en-us/library/t98kd6f7%28v=vs.80%29.aspx – Timo Geusch Aug 11 '11 at 15:15
@Timo: Ahh, corrected, that was a blinder & someone up voted it! ;-) – Alok Save Aug 11 '11 at 15:19
Wait, but following the provided links I see that those functions are in `mincore.lib`. And you are right, they are in version.lib . What is wrong? – Ivan P. May 16 '18 at 06:09

For VS2012 or 2013 add to Project Properties->Linker->Input->Additional Dependencies -> Add Version.lib

This is all that I needed to do. No need to worry about the dll, or the full path to the file,etc. – BuvinJ Dec 16 '16 at 21:37

I am also getting same error, while upgrading the VS6.0 application to VS2012 platform.

a. error LNK2019: unresolved external symbol _GetFileVersionInfoSizeA@8 referenced in function _main

b. error LNK2019: unresolved external symbol _GetFileVersionInfoA@16 referenced in function _main

c. error LNK2019: unresolved external symbol _VerQueryValueA@16 referenced in function _main

Resolution:

I found that it is due to missing reference to library "Version.lib".

a. For VS6.0 add it to Project Setting->Link->library modules

b. For VS2012 add to Project Properties->Linker->Input->Additional Dependancies and add full lib path to Include directory.
