      @biaspoint I am pleased you have your situation sorted. Purely OOI, because I like shell scripting, why did you bother to put the xargs into your command when dpkg -l | grep qt | awk '{print $2}' would deliver the same result? :) | xargs -n1 echo is a bit of a no-op?

      @hfinger said in How to fix installer file while installing: @sierdzio Do you mean something like /home/.qt5/? (This is Ubuntu.) Or something like /home/myhome/.qt5/? Note sure what you mean by local directory. I am a newbie. I usually install to /home/username/qt.

      @aha_1980 said in Project ERROR: Cannot run compiler 'clang++': You usually get *.pro.user.16fe832 files if you copy the project to another machine and open it there without deleting the .pro.user first. ...yes. I suppose that's a missing piece of information. The machine I developed on couldn't properly report to github, so I copied it to a flash drive.

      I've solved it. To handle long I did not have to send immediately reply (even though tutorial said that we have to). And delayed reply will be send. Also in extension, QDBusPendingReply<QString, QByteArray> reply = *call; setting expecting signature to \"say\" and not looking to xml interface.

      Hello, Sorry, it took me a bit of time to make the tests: A simple "Hello world" project runs correctly in Qt Creator? When using the external lib, the program crashes. I suspect an incompatibility of this old lib with Windows 10. I need to further investigated this issue... Many thanks for your help!

      Well, I consider to remove/change the code in my qt app to not depend on qtwebengine... It just displays some wheather maps (images) from an online source. I think I can realize that by fetching those images somehow from that online source and display them on an QLabel or so. I think qtwebengine is quite an overkill for that :)

      @SGaist Thanks for the reply. Indeed you are wright. It is very easy actually. I just compiled qt4.8.6 for my system. Then I found the sqlite project in sqldrivers. Compiled this library for my system, copied it and it works! Very easy. Learned again a lot! Thank you all for the great support!

      Ok, thanks for the reply. It pointed me in the correct direction and after many failures I finally figured it out. I guess you only learn when you need to dig deep. The only thing I had to do was install the correct version of openSSL. Since it is my first time I had no idea what the letter actually meant, I picked the first build, which was version g, I had to install version n. For all future wanderers, the only thing you need to do to make the client work is one of the two options: Just copy ssleay32.dll and libeay32.dll to working directory OR Install the latest version and set PATH to the folder where the two dlls are located. After that you can use QWebSocket without even knowing SSL exists. Just call: QWebSocket socket; socket.open( QUrl("someaddress") ); And, when the dlls are found the warnings disappear. That's it.

      Did not work with Firebird 3.0.3 embedded without a running server or firebird.exe -a. It just started to work as a real embedded database and not a tcp based connection when using an empty hostName. Instead of: const QString hostName = "localhost"; just const QString hostName = ""; That helped finally!

      Hi! You could install a custom message handler or force your application to die on warnings by defining QT_FATAL_WARNINGS.

      @Konstantin-Tokarev For normal web browsing that would be sufficient, yes. In my case we use a web-driven GUI. If I stop the script that needed too long (due to some network error or whatever) the GUI is missing on the device.

      These messages aren't critical, you can ignore them. What's important is, that you don't crash the application anymore.

      The problem is the same as in your other thread: you need to take care of the destruction order of your qobjects.

      Unplugging the tablet does not help. You have to at least temporarily disable the driver. The issue is described in detail here: https://bugreports.qt.io/browse/QTBUG-47548 You can stop the driver like this: net stop WTabletServicePro And restart the driver with this command: net start WTabletServicePro

      @M4RZB4Ni said: Hi When you dont have uSocket = new QUdpSocket(this) ; then uSocket->writeDatagram(xx will crash. as uSocket just point to random location. (dangling pointer) Next: QByteArray *priPackNuser; <<< also just a pointer. You should do ( as @SGaist mention) QByteArray priPackNuser; ( no *, means its real bytearray, not a pointer to one) So you change it from heap allocation to stack allocation. If you dont change to non pointer then you need QByteArray *priPackNuser = new QByteArray ; as else its a dangling pointer too! But no need for pointer to QByteArray here.

      Did you install MSVC2015 before or after Qt ? Can you see it in the Compilers tab ?
