      Hi, Because of chromium minimal compiler requirements. Nothing Qt can do about. Either use an older version or update your compiler to VS 2019 which is backward compatible with VS2017 and has less bugs.

      Problem fixed! The image data has to be written into the buffer returned by the QImage::bits() method. Here's the solution: auto sz = img.byteCount(); uchar* a = new uchar[sz]; memcpy(a, img.bits(), sz); m_lastFrame = QImage(imgSize.width(), imgSize.height(), imgFormat); memcpy(m_lastFrame.bits(), a, sz); // We write the image data into the new QImage delete[] a; And with a QDataStream: QByteArray arr; QDataStream ds(&arr, QIODevice::ReadWrite); ds.writeRawData((const char*)img.bits(), img.byteCount()); ds.device()->seek(0); m_lastFrame = QImage(imgSize.width(), imgSize.height(), imgFormat); ds.readRawData((char*)m_lastFrame.bits(), img.byteCount()); // We read the data directly into the image buffer Thank you so much for your help JKSH an koahnig!!

      @ed-wright Not sure, but probably you have to do a "nmake distclean" in between or it finds your license information. However, this is the opensource forum. You would need to approach the commercial, they have to able to give the proper answer.

      The mkspec says win32-msvc. Is this the correct one? I am building a 32 bit app with 32 bit Qt. Is the following line correct for the qmake.conf there? It compiles and runs with that line, but I don't know that if it's incorrect it just ignores it. I can't test it because I don't have that older architecture on my development PC. It's a build for one of the users of my application. QMAKE_CFLAGS_RELEASE = /arch:SSE

      hi @cc672012 you may have several problems, but the first one is that you assigned a 32bit compiler to a 64bit Qt version. That will not work.

      @dawidp said in Sqldrivers: Postgresql not found while it is installed and configured (win 8.1, Psql 9.6.6, Qt 5.10.0, MSVC2015_x64): And Qt installer was download from Qt website The Qt installer can install any officially provided Qt version, so you should know what Qt version you actually installed.

      @ambershark That seems to be the case, for some reason the tool copied the dlls from the MinGW-Folder instead of the MSVC ... every single dll was the wrong one. That also explains, why no SQL-Driver was loaded. Wrong plugin-folder as well.

      @pmh4514 I received an answer from Qt support, it solved the problem. Their answer below: On a virtual machine the OpenGL support might not be enough for rendering Qt WebEngine, so the quickest way to check if this is the case here is to do: set QT_OPENGL=angle on the command line or add: QGuiApplication::setAttribute(Qt::AA_UseOpenGLES); before the creation of the application object

      Hi and welcome to devnet, Qt Creator should auto detect the compiler for you. However what usually happens is that people install Visual Studio without checking the C++ option during installation thus they have a VS environment but nothing to build C++ code. You should first check that. Note that you also need to install the debugger separately. The one coming with VS is "internal" and cannot be used by other applications.

      @ifmihai I found that your steps also worked in my case, but I also installed the Universal CRT: KB2999226. That is because the Windows 10 SDK mentioned that non-Windows 10 platforms must install the Universal CRT. I installed Qt 5.8.0 on a Windows 7 platform.

      @Blacktempel said: Is that an existing bug in "include" ? Is there currently no way to include external source files where the path has space[s] in it ? I'm not sure; I have never used the include() function with space-containing paths. You can ask the Qt engineers by subscribing to the Interest mailing list and posting there.

      Hi, just to want add, while Qt Creator's capturing of your qDebug() output is usually 100%, but if you want to be sure to get everything, you could try running DebugView when your app exits.

      Did you really install VS2015? Do you have "Microsoft Visual Studio 2015" in Control Panel\All Control Panel Items\Programs and Features? If so then select it and press "Change" and make sure to install C++.

      Glad you found out and thanks for sharing your findings ! Thanks for the link, I've forgotten that page. What I usually do is an out of source build, so when there's something to change, you can just nuke the build folder and start fresh without to worry about what would need to be cleaned from the source tree. Since you have it working now, please mark the thread as solved using the "Topic Tool" button so that other forum users may know a solution has been found :)
