Unsolved How to use/include the QtNetwork Module
i'm trying to develop a simple application in C++ that sends Files between two computers over LAN. After some research i found out that the QtNetwork Module is the way to go. I do include the QTcpServer and QTcpSocket in my solution.
I added the following path to the Additional Include Directories of my project.
I then tried a very simple Code.
QTcpSocket* pTcpSocket = new QTcpSocket();
I get the "unresolved external symbol" Error which means that the functions are declared but are not defined. It seems to be a problem with the linking or building of the QtNetwork Module. On the Qt Website i found out that one should add the following line
QT += network
Since I have no experience with cmake or qmake i'm not sure where to add this line
Can anyone please recommend a simple example or explain how to correctly use the Module?
if you are using a CMake project add
find_package(Qt5 COMPONENTS Network REQUIRED)and then
target_link_libraries(MyApp PUBLIC Qt5::Network)where
MyAppis the name of your target
thanks for the answers. I'm actually using a Visual Studio 2017 Project and that's why I'm confused. There's no pro File under the Path of my Project :/.
Is it at all possible to use the Qt Network Module in a visual Studio 2017 Project ??
If you have the Qt Visual Studio Tools installed then right click on your project, go into the Qt Project property and in the modules tab put a tick next to Network
no I don't have the Qt VS Tools installed. How can i install them? Thanks !!
Now I installed the QT Vs Tools for VS 2017. Do I have to start new Project to add the Network Module or can i add it to my already exisiting VS Project?
Last time I used the VS Tools (that was with VS 2013) it required to start a project from scratch, not sure if they introduced a "convert to qt project" feature since
