How can i static build qt project in Visual Studio

Another way is to build your own version of Qt with all unused features disabled. That requires some work as well.

Depending on the modules you use, you can shave off some things like unused image/database plugins.

You need to adjust your PATH environment variable so the dlls are found during runtime.

In your first post you wrote where you installed your Qt to, so I would start searching in there...

As you can see in your output you're building for MinGW, not MSVC. Adjust your environment (hint: Visual Studio Command prompt) so cl.exe is properly found by configure.bat/cmake.

No - I already told you that you have to make sure that configure picks up the msvc compiler and not the MinGW one as you can't mix the two compiler. So clean up your build dir and start over.

I seriously don't understand qt, I just want to compile as static and I couldn't do it in 3 days..

Have 3 folders (you can name them however you want):

/src
    //this is where Qt sources are
/build
   // this is where you build
/install
   //this is where you install

From start menu open x64 Native Tools Command prompt for VS. You don't need admin privileges.
cd to your build directory (not src!)
In your build directory:
../src/configure -prefix <full path to install dir> -static -static-runtime <any other options you want>
cmake --build . --parallel
cmake --install .
if you also built debug version then also cmake --install . --config Debug
That's it, 3 or 4 commands.

@Chris-Kawa

it was running fine but still gave an error

Chris Kawa · 15 Jan 2023, 22:29

Read the third line.

@Chris-Kawa

cd c:/qt-static/build
c:/qt-static/src/configure -debug-and-release -commercial -confirm-license -static -platform win32-msvc2019 -nomake examples -nomake tests -prefix C:\Qt-Static\install
cmake --build . --parallel

build success.

install error

I think I did all the steps correctly but the result is still like this.

Don't re-run configure in a directory that you have a failed build in. If a build fails clear the build directory and start over from clean state: empty dir, configure, build, install.
Don't pass -platform win32-msvc2019. Platform is deduced from the environment i.e. the command prompt bat you used. Note that you're building 32bit version. If you want to build 64bit version start the x64 command prompt.
Don't try to build modules you don't need. In the src dir you have directories like this:

qt3d
qt5compat
qtactiveqt
qtcharts
...

Each of them is a Qt module. You need qtbase and qttools. Others are optional. Go through the list and for each module you're not planning to use exclude it via parameter of configure. Some of those are also not supported in a static build (you got a message about it in your previous post). Exclude those too. For example to exclude qtwebengine pass -skip qtwebengine. Do that for every module that is not supported or you're not planning to use.
