Re: [Interest] Qt5.15 from source on centOS 7
Hej Mike and Simon, allright – although I successfully (conventionally) installed a more recent gcc on my centOS 7 I ran into further trouble with the actual Qt5.15 compilation. Now I brought all back to centOS defaults including gcc4.8 and Qt5.9. As suggested by you I will now give it a try with the Developer Toolset and get back later.

Re: [Interest] Qt5.15 from source on centOS 7
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; ^~~~ echoserver.cpp:33:19: Fehler: Variable »QSslKey sslKey« hat Initialisierung, aber unvollständigen Typ QSslKey sslKey(&keyFile, QSsl::Rsa, QSsl::Pem); ^ echoserver.cpp:36:40: Fehler: »QSslSocket« wurde nicht deklariert 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.

Re: [Interest] Qt5.15 from source on centOS 7
Build OpenSSL 3 and add its install directory lib/pkgconfig to PKG_CONFIG_PATH and choose -openssl-linked as one of the config parameters. If you can get through configure, it should build.

If you can get through configure, it should build. OpenSSL 3 isn't supported in 5.15. Use the very latest release from 1.1, but no older and no newer. Then there's the question of whether you want to ship OpenSSL libraries with your product. If you do, then you must also keep an eye to OpenSSL security advisories and make proper and timely updates to your release. Be prepared to make new builds and release to customers once per month. If you can't sustain this rate, then don't ship OpenSSL. You don't have to do it: the default build doesn't link to OpenSSL, but instead tries to find it at runtime and dlopens() it. That places the burden of providing OpenSSL and keeping it up to date on your user, not you. If they choose to be vulnerable by choice or by ignorance, it's not your fault. If you choose this route, make sure your application works properly when OpenSSL 1.1 is missing. By "properly", I mean "doesn't crash left and right". Please make sure that it is not silently falling back to unencrypted connections where encrypted were required. If your application requires encrypted connections to work at all, then display a dialog with a link to documentation on how to install OpenSSL. PS: OpenSSL is the most visible and most important library when it comes to patching security vulnerabilities, but is not the only one. You should do the same for ALL libraries you ship with your application, and that includes ALL the libraries that are bundled inside Qt's source. For example, the just- released Qt 5.15.5-LTS includes a vulnerable version of zlib, so you should patch it. Better yet, don't use bundled libraries. -- Thiago Macieira - thiago.macieira (AT) intel.com Cloud Software Architect - Intel DCAI Cloud Engineering ___ Interest mailing list Interest@qt-project.org https://lists.qt-project.org/listinfo/interest
