Need cloud storage with c++ and OSX

The problem seems to be in FMX.TMSCloudCustomFlickr.pas  I would only send Embarcadero that file, files in the "uses" section, or otherwise needed to support the c++ source code:
    TMSFMXCloudFlickr1->App->Key = FlickrAppkey;
    TMSFMXCloudFlickr1->App->Secret = FlickrAppSecret;

    #if defined(TARGET_OS_MAC) || defined(_Windows)
        // windows and mac use a shared documents folder requiring a subfolder
        UnicodeString us = IncludeTrailingPathDelimiter(System::Ioutils::TPath::GetDocumentsPath());
    #else
        // ios and android setup special document folders for each app
        UnicodeString us = IncludeTrailingPathDelimiter(System::Ioutils::TPath::GetDocumentsPath());
    #endif
    us += "flickr.ini";
    TMSFMXCloudFlickr1->PersistTokens->Key = us;
    TMSFMXCloudFlickr1->PersistTokens->Section = "tokens";
    TMSFMXCloudFlickr1->LoadTokens();

    int acc = TMSFMXCloudFlickr1->TestTokens();

    if (!acc)
    {
        TMSFMXCloudFlickr1->RefreshAccess();
        TMSFMXCloudFlickr1->DoAuth();
    }

I don't have a complete list yet.
