error: ‘SHGetKnownFolderPath’ was not declared in this scope

I know this question asked before, my CPP file is :

#include <shlobj.h>
int main(int argc, char *argv[])
{
    PWSTR pszPath;
    HRESULT hr = SHGetKnownFolderPath(&FOLDERID_Startup,0,NULL,&pszPath);
}

And i am using Linux Mingw compiler to compile it for windows by this command :

i686-w64-mingw32-gcc hub.cpp

or

x86_64-w64-mingw32-g++ hub.cpp

And i get :

In function ‘int main(int, char**)’:
error: ‘SHGetKnownFolderPath’ was not declared in this scope
                 &pszPath);
                     ^

Adding these to the header doesn't help, and i get same error:

#define WINVER 0x0600
#include <windows.h>

or

#define WINVER 0x0600
#define _WIN32_WINNT 0x0600

And I've looked into shlobj.h, and SHGetKnownFolderPath is in it.

How can i fix it ?

EDIT :

The change my friend ssbssa suggested in the comments to put #define _WIN32_WINNT 0x0600 before #include <shlobj.h> , raise a new error and a new note :

hub.cpp: In function ‘int main(int, char**)’:
hub.cpp:8:69: error: invalid initialization of reference of type ‘const KNOWNFOLDERID& {aka const _GUID&}’ from expression of type ‘const GUID* {aka const _GUID*}’
  HRESULT hr = SHGetKnownFolderPath(&FOLDERID_Startup,0,NULL,&pszPath);
                                                                     ^
In file included from hub.cpp:2:0:
/usr/share/mingw-w64/include/shlobj.h:755:10: note: in passing argument 1 of ‘HRESULT SHGetKnownFolderPath(const KNOWNFOLDERID&, DWORD, HANDLE, WCHAR**)’
   STDAPI SHGetKnownFolderPath (REFKNOWNFOLDERID rfid, DWORD dwFlags, HANDLE hToken, PWST

I can see the error say , It expect a pointer and I gave him an adress, but i don't know how to declare it in the right way.

Try adding #define NTDDI_VERSION 0x06000000 before #include <windows.h>
