undefined reference to ... - googleapis::client - analytics api

[Csaba Bordás]

I'm trying to build analytics api and got this kind of error message:

../google-api-cpp-client-master/build/lib/libgoogleapis_http.a(media_uploader.cc.o): In function `googleapis::client::MediaUploader::CreateMultipartPayloadReader(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >*)':
media_uploader.cc:(.text+0x1a15): undefined reference to `googleapis::client::NewCompositeReaderListAndContainerDeleter(std::vector<googleapis::client::DataReader*, std::allocator<googleapis::client::DataReader*> >*)'
media_uploader.cc:(.text+0x1a27): undefined reference to `googleapis::client::NewManagedCompositeDataReader(std::vector<googleapis::client::DataReader*, std::allocator<googleapis::client::DataReader*> > const&, googleapis::Closure*)'
../google-api-cpp-client-master/build/lib/libgoogleapis_http.a(http_request_batch.cc.o): In function `googleapis::client::HttpRequestBatch::PrepareFinalHttpRequest()':

collect2: error: ld returned 1 exit status


Very strange that got no errors if I write this:

        flow_->set_default_scopes( "https://www.googleapis.com/auth/analytics.readonly" );

but the error appears if the line changed to this:

        flow_->set_default_scopes( google_analytics_api::AnalyticsService::SCOPES::ANALYTICS_READONLY );


And I always got the error message above when I'm trying to create the AnalyticsService object:

     whatever I'm writing this:
        analytics_.reset(new AnalyticsService(config_->NewDefaultTransportOrDie()));
     or this:
        AnalyticsService* ga = new AnalyticsService(config_->NewDefaultTransportOrDie());


I have set the paths for the -I and -L flags well!

Can somebody help me please?
I'm struggling with this api for a long time...
