  @Christian-Ehrlicher Thanks for your reply. I have used a newly installed machine with only qt 5.14 compiled, and I did not change any source code so it is strange if I by error have somehow included any Qt4 headers. I see that the build also fails at https://github.com/KDAB/GammaRay (ERROR: could not open HSTS store at 'C:\Users\appveyor/.wget-hsts') but I guess this is unrelated. Best Daniel

  I understand your frustration but there's nothing we can do here. Qt just provides tools. Someone just made a poor use of them. I'm a game engine programmer myself so I can tell you that it can be hard to diagnose these types of issues and it is often hard to even know they exist. It might be a bug, bad network design or a simple case of "works on my machine". Sometimes it's an entirely different team that makes a crappy launcher for otherwise good game or vice versa. Try to contact the creators. Developers often don't read forums but there's a lot of them on social media like twitter or reddit. Just be polite and keep your head cool. They're people too. Try to imagine how you'd like to be approached when something you made doesn't work for somebody ;)

  I solved by creating a stored procedure then passing the values to a json object. Created a trigger on Insert then execute the procedure. In my app it detects the source with switch case. I followed some examples and implemented to my needs.

  It's telling that the majority of the code examples in that PDF are in Visual Basic, and C++ is treated as a 2nd class citizen in it :-( The 2nd method (dumpcpp with only an .h) is at least technology from this century so I understand why you prefer it. Try to see if there's a pattern to the SEG faults, perhaps there's some extra initialization you need to do due to that missing staticMetaObject. The IDispatch errors are a symptom of inconsistencies in the .tlb file but are glossed over by Visual Basic and C#, but I think they can be fixed with some type coercing, e.g. static_cast<IDispatch*>(ptr) Good luck! P.S. There might actually be a 4th alternative, especially if you're only using a subset of that Robot library: write a "wrapper" COM .dll in C#, I think it's called a CCW (Com Callable Wraper) that exports the stuff you want in a more modern way, which then can be consumed by Qt C++.

  Side note for posterity, but I think I found a way to go about it which works better for me and doesn't involve messing around with MSVC. For whatever reason, downloading the full Pylon SDK package with the viewer and everything doesn't work very well for me and doesn't let the cameras be recognised as such by my device. However, if I use only a runtime (I used v5.2, but you could probably use a different one too), it works and gets recognised. QCamera now also recognises the camera, though it fails to set proper viewfinder settings and therefore doesn't work. It also finds 4 cameras instead of just one, which I think is a quirk of the driver or something, since OpenCV does the same thing. I would prefer to do everything with Qt and not be dependent on any external framework, so if there's any pointers on how to set proper viewfinder settings that would be much appreciated, but for now this is fine. What works and does recognise the camera while reading properly from the camera is OpenCV. In order to be used with MinGW, it has to be made from source with make, but I've managed to make it work on my machine. I followed this guide on the subject, and it worked for me after restarting. Anyway, I finally have something I can work on again, and I'll consider this question solved. Thanks for the help.

  @SGaist, Ok, I think I get where you're both going now. I should have a Database handler class with separate queries for reading and writing each table. No need to over-complicate it by trying to abstract the queries themselves. If I'm honest with myself, I'm probably trying to do that because SQL is like that cute girl in high school who intimidates you a little bit. You're a little afraid to talk to her, and if you do work up the courage, you want to get as much done in that one conversation as possible. :-)

  @bondrusiek said in Zlib library error | undefinied reference to: when I use function from zlib like gzopen Compilator gives error message: undefined reference to 'gzopen' It's the linker complaining indeed... Are you sure you have the shared object for Qt zlib library available? How do you install Qt framework? Is it configured for -qt-zlib? See documentation regarding 3rd party libraries

  Since you have the Docker-compose file, you can directly build the test server. Maybe just launch it before starting the test suit.

  Sorry for the late reply, CLIPS is a rule-based programming language, its interface "clips v6.4" is a command-line interface. So my task is to design a Qt GUI to better represent the output from CLIPS. Currently, I am facing issues with the importing of clips library into Qt VS. In sourceforge, a CLIPSwrapped library is provided, however, I am not sure how to "import" this wrapped library in Qt VS such that I can call the CLIPS functions in my Qt main.cpp. Please let me know on what I should do. Thank you.

  Hi, This the source package, you have to built it in order to use it MinGW build Visual Studio 2008 build Visual Studio 2010 build You can use 1 after you built it, and 3 to 4 directly in Qt Creator provided that you installed the corresponding compilers. Yes, you can have multiple versions of Qt in parallel no problem with that. No, they will not. Up to VS2015, there's no compatibility between Visual Studio versions. VS2017 is the first one that is backward compatible with VS2015. Also note that, if your really need to work with Qt 4, you should at least go with Qt 4.8.7 which is the latest and last version of the 4 series. Even more important, Qt 4 has reached end of life a long time ago, you should rather start with Qt 5.

  Exactly, why we have to include this: QWheelEvent wheelEvent( QPoint( 5, 5 ), we->delta(), we->buttons(), we->modifiers(), we->orientation() ); QPoint( 5, 5 ) is pos or global pos? What is pixelDelta? What does mean that it contains the scrolling distance in pixels on screen?

Your question/problem has no relation to Qt) I have is to do what the error message suggests: you need the OpenSSL libraries. Download them and put them into same directory where wsdl2h.exe is...
