Hi all. After failing to build VTK 8.2.0 with Qt5.12.12, I decided to build it without Qt. This went without errors. But I am puzzled by one thing. I selected BUILD\_EXAMPLES, but as far as I can see no examples were built. Maybe I’m not looking in the right place.  
Which examples should I expect to get built, and where?  
Thanks,  
Gib

VTK-9.3.0 excellent works with Qt-6.7.0 in Windows and Linux

Well that’s interesting. There presumably is a binary download for Qt-6.7.0.  
Could you tell me what cmake settings for Qt in the vtk build you used?  
Thanks.

I split this post off the “Welcome to Discourse” post. Please ask new questions in new topics.

Do you mean `VTK_BUILD_EXAMPLES`? That’s the one you need to enable.

To build examples, use ctest:

`ctest -R VTKExamples`

Why ctest? It lets us test and report test results in VTK’s continuous integration builds to make sure the examples work.

Hello,

You can get the latest Qt here: [Get and Install Qt | Qt 6.7](https://doc.qt.io/qt-6/get-and-install-qt.html). There are desktop installers for Linux, MacOS and Windows (presumably compiled with Visual Studio 2017-2022).

If you have an odd combination of OS, compiler and architecture, then I recommend building Qt from sources with the Conan ([Introduction — conan 2.5.0 documentation](https://docs.conan.io/2/introduction.html)) recipe from here: [qt - Conan 2.0: C and C++ Open Source Package Manager](https://conan.io/center/recipes/qt?version=6.7.1). Building Qt and its entire dependency tree with Conan (think of Java’s Maven) is relatively easy. All you need, in addition to have a developer toolset installed, is to install a recent version of Python and install Conan with a `pip install conan`.

best,

PC
