I am using Qt and QTcpSocket to create a small chat client/server application.
When I compile my code, the compiler returns the following error:
main.cpp:3:22: fatal error: QTcpSocket: No such file or directory
This refers to #include <QTcpSocket>.
Where is this library located and how can I install it?
You need
in your .pro file. Otherwise the module in which those headers are defined/libraries are built won’t be loaded.
