Hi, We already have condition for QUrlQuery class as below. It will be used only if Qt version is >= 5.0.
#if QT_VERSION >= 0x050000 // Extract filename and query from encoded URL QUrlQuery query_data(reply->url()); QString file_name = query_data.queryItemValue("filename"); QString query = query_data.queryItemValue("query"); #else QUrl url(reply->url()); QString file_name = url.queryItemValue("filename"); QString query = url.queryItemValue("query"); #endif In your case, it may possible that during qmake - Qt version is detected as 5 but you are compiling against Qt 4 so application is not able to find the QUrlQuery class. Can you please share console log and Makefile when you run the qmake command with project file ?
