QSctpSocket does not compile

[hape]

Hi,
i'm trying to play around with QSctpSocket, Linux (Ubuntu 18.04), Qt 5.9.5
QtCreator won't compile, g++ says:

../sctptest/main.cpp:8:5: error: unknown type name 'QSctpSocket'; did you mean 'QTcpSocket'?

(i really meant QSctpSocket)

.pro contains:

QT -= gui
QT += network

CONFIG += c++11 console
CONFIG -= app_bundle

what am i missing?

thanks, HaPe

Hi,

Might be a silly question, but are you sure you are using Qt 5.9.5 to build your application ? QSctpSocket has been added in Qt 5.8.

Hi
Just as a note.
I tried in my Mint linux with Qt5.9.1
and it seems not active.

[SGaist]

It is unless Qt was built with SCTP disabled. The second condition is to allow QDoc to do its magic.

@SGaist
Well it is a version from online installer.
So i do wonder why it seems compiled without.

@SGaist and others
This is standard Ubuntu Qt package (open source version); i do have /usr/include/x86_64-linux-gnu/qt5/QtNetwork/qsctpsocket.h which starts with "#if !defined(QT_NO_SCTP) || defined(Q_CLANG_QDOC)"
So how can i check if QSctp is supported? And what is Q_CLANG_QDOC?
Do i need to install additional packages? Linux Sctp module is enabled (which shouldn't make a difference when compiling).

Hi
Does your .h file also show the class part in
grey ?

also could you test if QT_NO_SCTP is defined ?

[hape]

@mrjj indeed, class QSctpSocket is greyed out in QtCreator and QT_NO_SCTP is defined. So probably Ubuntus Qt package is not compiled with SCTP support?

[J.Hilk]

surprisingly, the OnlineInstaller variant for MSVC2015

is shipped with QT_NO_SCTP defined as well

On MacOS QT_NO_SCTP is not defined

Both 5.11 from the online installer.

@hape
seems like you'll have to compile the Qt libs yourself to enable the feature for your OS-distribution

@J.Hilk i think we will completly forget about Qt Sctp support and write a wrapper for the C-socket interface.
