I couldn't get mklink2.cc to compile until I made the attached changes.
It appears that CoCreateInstance() and sl->lpVtbl->QueryInterface() are
looking for pointers to values in certain arguments instead of the values.
Almost the exact same code is used in src/winsup/cygwin/shortcut.c except
for the '&'s and it compiles cleanly. Both functions defined in mklink2.cc
are declared extern "C" so the function calls should work the same.
Here are the relevant pieces of code.
src/winsup/cinstall/mklink2.cc (make_link_2):
23: CoCreateInstance (CLSID_ShellLink, NULL,
24: CLSCTX_INPROC_SERVER, IID_IShellLink, (LPVOID *) & sl);
25: sl->lpVtbl->QueryInterface (sl, IID_IPersistFile, (void **) &pf);
src/winsup/cygwin/shortcut.c (check_shortcut):
85: hres = CoCreateInstance (&CLSID_ShellLink, NULL, CLSCTX_INPROC_SERVER,
86: &IID_IShellLink, (void **)&psl);
87: if (FAILED (hres))
88: goto close_it;
89: /* Get a pointer to the IPersistFile interface. */
90: hres = psl->lpVtbl->QueryInterface (psl, &IID_IPersistFile, (void
**)&ppf);
src/winsup/w32api/include/objidl.h:
640: EXTERN_C const IID IID_IPersistFile;
src/winsup/w32api/include/olectlid.h:
76: extern const GUID IID_IPersistFile;
src/winsup/w32api/include/shlguid.h:
13: extern const GUID CLSID_ShellLink;
28: extern const GUID IID_IShellLinkA;
68: #define IID_IShellLink IID_IShellLinkA
src/winsup/w32api/lib/shell32.c:
6: DEFINE_SHLGUID(CLSID_ShellLink,0x00021401L,0,0);
21: DEFINE_SHLGUID(IID_IShellLinkA,0x000214EEL,0,0);
src/winsup/w32api/lib/uuid.c:
226: DEFINE_GUID(IID_IPersistFile,0x10b,0,0,0xc0,0,0,0,0,0,0,0x46);
