    I'm having an issue building the simulationserver example.

    I, Running QT Creator 17.0.0 "Built on Jun 17 2025 16:32:24 based on Qt 6.9.1 (MSVC 2022, x86_64).

    I'm using the qtopcua supplied with Qt6.9.1 for develpmment.

    I built the main qtopcua without issue, but when I try to build the example simulation server I get the following error when I try to build it.

    In the example I am providing I told the maintenance tool no, but in a previous build I told it yes and it cannot find the missing addon, and stalls.

    It calls the maintenance tool and is looking for OpcUa and cannot find it.

    I'm excited that I have gotten this far I just need some clarity.

      Qt6OpcUa only appears on my computer as a directory or a cmake file. I could not find any libraries or plugins.

        @dencla You have to build it yourself and install it.

        I would like!

          @sbela I thought that I did that when I did the build on qtopcua. Or am I missing something?
          It said that it was successful.

              Did you install it? cmake --install . This assumes that you had your CMAKE_PREFIX_PATH set correctly, for example by using the qt-cmake tool: https://doc.qt.io/qt-6/cmake-build-on-cmdline.html#qt-cmake

                Just an Update. I have been able to build bothe the client and server example application. Thanks to all!! I was exstatic aa few weeks ago and was able to get a device to connect the new clinet that i created to its opc ua Server and it kept failing. I was successful using MinGW 64 6.9.1, but then I was told that that version did not include security and I needed to use MSVC 2019 x64. I have been trying to rebuild it eversince under MSVC 6.10.1 64 with out success, I keep gettin build errors of all sorts. I fix one thing then I get another. Are ther instructions on how to build OPC UA under either platform with security enabled?

                  Glad to hear that you've made progress!

                  Let's continue the security question at https://forum.qt.io/topic/163829/opc-ua-client-security
