Re: pgAdmin 4 as Web application

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 ?

Thanks,
Neel Patel
