[Interest] Qt5.15 from source on centOS 7

[Alexander Carôt]

Succes !! Thanks so much for this hint of using the Developer Toolset ! Qt5.15 is compiled and installed just fine but now a new issue arises which might have a different cause but I am embedding it into this thread anyways: My app contains a secure websocket and anything related to ssl is not available obviously:


echoserver.cpp: In Konstruktor »EchoServer::EchoServer(quint16, bool, QObject*)«:
echoserver.cpp:18:63: Fehler: »SecureMode« ist kein Element von »QWebSocketServer«
                                             QWebSocketServer::SecureMode, this)),
                                                               ^~~~~~~~~~
echoserver.cpp:27:23: Fehler: Aggregat »QSslConfiguration sslConfiguration« hat unvollständigen Typ und kann nicht definiert werden
     QSslConfiguration sslConfiguration;

     sslConfiguration.setPeerVerifyMode(QSslSocket::VerifyNone);
                                        ^~~~~~~~~~
echoserver.cpp:40:25: Fehler: »class QWebSocketServer« hat kein Element namens »setSslConfiguration«
     m_pWebSocketServer->setSslConfiguration(sslConfiguration);
                         ^~~~~~~~~~~~~~~~~~~
echoserver.cpp:52:56: Fehler: »sslErrors« ist kein Element von »QWebSocketServer«
         connect(m_pWebSocketServer, &QWebSocketServer::sslErrors,
                                                        ^~~~~~~~~
echoserver.cpp: In Elementfunktion »void EchoServer::onNewConnection()«:
echoserver.cpp:190:14: Fehler: »class QWebSocket« hat kein Element namens »ignoreSslErrors«
     pSocket->ignoreSslErrors();


I believe there is another module to be compiled, however, since I build everything I currently don't know how to proceed next.

Thanks for helping me out also with this,
best

Alex
