Installation and Deployment

@SGaist ; @Christian-Ehrlicher you guys are the best. FFMpeg-6.1.1 links and compiles with QT just fine! Thank you very much again.

I tried to create a minimal CMake project, which uses OpenGL - it does find it well. This is the output: "-- Detecting C compiler ABI info -- Detecting C compiler ABI info - done -- Check for working C compiler: /usr/bin/cc - skipped -- Detecting C compile features -- Detecting C compile features - done -- Detecting CXX compiler ABI info -- Detecting CXX compiler ABI info - done -- Check for working CXX compiler: /usr/bin/c++ - skipped -- Detecting CXX compile features -- Detecting CXX compile features - done CMake Warning (dev) at /usr/share/cmake-3.23/Modules/FindOpenGL.cmake:315 (message): Policy CMP0072 is not set: FindOpenGL prefers GLVND by default when available. Run "cmake --help-policy CMP0072" for policy details. Use the cmake_policy command to set the policy and suppress this warning. FindOpenGL found both a legacy GL library: OPENGL_gl_LIBRARY: /usr/lib/aarch64-linux-gnu/libGL.so and GLVND libraries for OpenGL and GLX: OPENGL_opengl_LIBRARY: /usr/lib/aarch64-linux-gnu/libOpenGL.so OPENGL_glx_LIBRARY: /usr/lib/aarch64-linux-gnu/libGLX.so OpenGL_GL_PREFERENCE has not been set to "GLVND" or "LEGACY", so for compatibility with CMake 3.10 and below the legacy GL library will be used. Call Stack (most recent call first): CMakeLists.txt:14 (find_package) This warning is for project developers. Use -Wno-dev to suppress it. -- Found OpenGL: /usr/lib/aarch64-linux-gnu/libOpenGL.so -- Configuring done -- Generating done" I also tried adding set(OpenGL_GL_PREFERENCE GLVND) and set(OpenGL_GL_PREFERENCE LEGACY)

I haven't use the plugin myself but from my understanding you should have the project already configured for MSBuild and it should be possible to build it from the command line using MSBuild.exe.

I had the same issue. In my case, it was a wrong run configuration. (left pane) "Projects" -> "Build & Run" -> "Run" -> "Run" -> "Run configuration:" Make sure the you have selected the right configuration. [image: 50cf3394-cbe9-4c6e-93c5-7a56884a9756.png]

@Christian-Ehrlicher Tysm! Hv a great day!

I also may have posted this in the wrong thread. I thought I was posting it in one of the many threads reporting an identical error. This thread appears to have been reporting a similar qt build issue. Too many threads with too many qt build issues

@Karlovsky120 & @JonB , same error when i compile my project in msvc_2019 compiler(qt creator 13.0.1) with qt version 6.7.1 . I do the some library that needed but also having same error . How to solved ????

Open source (under the GPL/LGPL) only means that if someone gives you the binaries they must also provide the source code. There is no obligation to provide anyone with the binaries (or even the source code). Everybody is free to choose to whom they want to give GPL/LGPL software. As @Christian-Ehrlicher already mentioned the Qt source can be found on GitHub. You can even compile a full Qt from that (which is a little more trouble than just using the installer). I assume that you even need to build the docs. Though you can easily access all the docs at docs.qt.io (assuming this is not also blocked for Russia). There used to be tools to download whole webpages (following all links) for offline reading. If these kind of tools still exist you could grab the full docs from their website. BTW, there is no offline installer for the open source version anymore.

update for anyone else this affects: after installing openssl-3.3.1 form source, I also had to add /usr/local/lib64 to the ldconfig search path (sudo ldconfig /usr/local/lib64). This is the default openssl-3.3.1 install location and had not been used by anything else on my Debian 11.3 system

But, if you install https://www.python.org/ftp/python/2.7.18/python-2.7.18.msi then you will get arm-none-eabi-gdb-py.exe starting! [image: fd2fa350-06a1-4bb0-8e41-5df957dd4a35.png]

If you are using CMake to build your Qt Application, you could think of using cpack. In the cpack generators you have both NSIS and the Qt Installer Framework (IFW), and also WIX. See also Qt's CMake deployment API for more details.

You still don't follow the instructions... You need the source code to compile something.

If memory serves well, that's where QtChooser comes into play.

@YordanBonev Hello, did you find anything for this particular subject? The company I am working for is stuck in Qt5.15 for a while, but I need to have a more recent Chromium version. Version 87 mainly lacks a lot of features from modern CSS, for us.

Your original problem most likely stems from the fact that you didn't have MSVC properly set up in your command line. One way is to start the Developer Command Prompt for your Visual Studio version and execute qmake.exe inside that prompt. Another way is to call something like call "C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Auxiliary\Build\vcvarsall.bat" amd64 on your command line to set up MSVC and after that call qmake.exe.

where make.exe, where sh.exe and where bash.exe willshow you from where it's picked up

Thanks that is working.
