@tuzepoito said in How do I use Qt headers in a CMake sub-project?: I think I have a solution, or maybe a workaround. Why workaround? If you want to use a library, you have to link against it what you're doing now - how should this be a workaround?

AFAIR, they match the mkspecs that you can find in your Qt installation.

Maybe I expressed myself incorrectly. By native I meant that uses the WinMain function as an entry point, for example. Something like the code in the link I've poste. But If you can provide some example code on HOW I can use Qt and the win32 APi and Direct X 11, I'd appreaciate it. I have not been able to find ANYTHING online. Just a simple open a window and draw a circle or something will do. I want to know how con configure the .pro so that it will find all the appropriate libraries and the code will compile.

Thanks for your help with this. The Qt Creator editor is a good alternative. I did run Dependency Walker - long time since I have looked at the output from this and not sure what I am seeing right now, but I've pasted the an abreviated version of the output below (too long to paste the whole thing) if it tells you something.

@oblivioncth said in Building 5.12.1 32-bit static Qt for MSVC on Windows 10: The system cannot find the file specified (qgltf5.pdb).: C:\Engineering\Development\Qt\Tools\QtCreator\bin\jom -j 8 I wanted to keep the versions for the standard and static versions consistent, but its not like it would really matter since its just a small revision difference. So, I attempted to build 5.12.3 this time and while I was at it I grabbed the dynamically linked version of 5.12.3 from the maintenance tool as well. This time I ran the Visual Studio Native Tools command prompt as an administrator since I figured that had a shot at mattering even though I didn't see it mentioned anywhere and wasn't doing this is a UAC protected directory. And... it built completely with no issues and I was able to produced a statically linked version of the app I'm working on like I wanted to. I don't know if there was a bug in the 5.12.3 source, if it actually was running the prompt as administrator, if there was just a simultaneous access issue with some of the files/tools on the last run, or if it was just a fluke, but everything works fine now. The build ended on the same two lines but succeeded in copying qgltf.pdb instead of not finding it and the process took much longer than the previous attempt, so I'm guessing that there were errors earlier in the process that didn't stop the build script so I didn't catch them.

@SGaist said in Win32 static linking?: Qt Creator architecture has nothing to do with the architecture of your application. To build a 32bit version of your application, use the 32bit package for MSVC2017. The same goes for the 64bit version. Yeah, that worked. When I tried it in 5.12.0 and failed, there must have been something misconfigured. I currently don't know for the static version, however when building the dynamic version you can say to configure that it should build dynamic backend selection. Following some info from another post, I tried the following configure.bat options: -prefix "C:\Qt\Qt5.12.2\5.12.2\msvc2017sr" -release -platform win32-msvc -confirm-license -opensource -nomake examples -nomake tests -static -static-runtime -opengl dynamic -angle -combined-angle-lib -no-feature-d3d12 Now it works on the 32-bit Windows machine I used to build Qt and the application (and still works fine on the 64-bit machine I can also build it on), but when I run it on another Win7 64-bit machine that has never had Qt installed on it, I just get the window frame again. Is it looking for a DLL? I only have a nebulous idea of what some of those configure options actually mean, so I don't know what to try next.

@sirop Vielen Dank für den Tipp. Ich habe jetzt herausgefunden das DLLs gefehlt haben. Dies habe ich herausgefunden als ich selbst die Anwendung ohne IDE gestartet habe. Da kamen entsprechende Fehlermeldungen. Nach einfügen dieser fehlenden DLLs funktioniert es nun. Vielen Dank für die Hilfe und an alle ein schönes Wochenende und einen guten Start in die neue Woche. Grüße Sven

I wrote to chromium developers, so, here is the summary It is not a crash, it is a failed debug assertion It happens if: you use webview's chromium backend (recent versions, old versions don't have this assertion) some part of you code consumes COM and that code's thread is not explicitly initializing COM via CoInitialize or CoInitializeEx My code uses a library that was not properly initializing COM in its threads before calling CoCreateInstance. Calling CoInitialize should fix my issue, but I cannot prove it until I have access to that libraries source code. What is left to be done by qt/webview team is to fix the failed assertion on "Chrome_InProcGpuThread" which is not created by user.

Thanks, I tried it without success. For me it seems the documentation is not up to date as the named folder sturcture is not existing in the EnterpriseDB installer installed version or in the official sources. I also looked whether there is something like an extra psql module to download, but have not found anything.

You are right! It is my error, rebuild all project with full delete old directory and all work fine. Thanks for fast and good answer!

@milan said in Qt App runs and exits with crash 1073741819: But, I do not understand which widget is using OpenGL QQuickWidget (=> QML) Unless you explicitly tell it to use the software rasterizing backend. e.g. either via code QQuickWindow::setSceneGraphBackend(QSGRendererInterface::Software); or via environment variable QT_QUICK_BACKEND=software (before QApplication instantiation)

@jsulm there was in fact a problem with window3d() that MinGW didnt complain about! Thanks! @JonB no I had commented out only up to the second screenshot, so that's why this was the problem. And about the second issue, to be honest I adapted the constructor from an older version of the application and it also had &argc. At one point I also noticed it and now I tried out both and both work.

@EinderJam said in "Mismatch detected for RuntimeLibrary" when trying to statically compile with a static build of Qt: Before building, using this tutorial, I modified qt-everywhere-src-5.11.1\qtbase\mkspecs\msvc-desktop.conf and replaced every -MD by -MT Build process went fine. If you changed the Qt compilation flags at some point, did you clean out absolutely everything before rebuilding? Many times it seems bits get left over which have been compiled with previous flags.

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.

@SGaist Thanks. I will try it.

There's an initial release of the VS-AddIn here Sure there is, just build qtbase statically then build only the modules you want by hand or exclude all the modules you don't want when calling configure.

It went in but after the release of 5.8.0. So if you need it, either check the 5.9 alpha or build from Git.
