[Qt6][Windows] How To Clean Build in Source Dir

BosGemiler

Hi all,

I am trying to build Qt6 source statically on Windows platform. After configuration is done, I got some errors in build step. And I want to clean my build directory before rebuild.

In Qt docs, it is described as ;
If you later need to reconfigure and rebuild Qt from the same location, ensure that all traces of the previous configuration are removed by entering the build directory and running nmake distclean or mingw32-make distclean before running configure again.

But there is no any makefile in my source directory to be able run. As a result when I tried to run mingw32-make distclean I receive an error that makefile couldn't find.

How can I clean my build directory before rebuilding ? Why don't I have a makefile in my build folder ?

Meanwhile, I tried to make clean with cmake with below command. But I think that's not what I need.

>cmake --build . --target clean
[2/2] Cleaning all built files...
Cleaning... 486 files.

Configure and build commands I have used ;

>configure -static -release -prefix C:\QtStatic -skip qttranslations,qtdoc,qttools,qt3d,qtlanguageserver,qtmqtt,qtmultimedia,qtquick3d,qtquicktimeline,qtsensors,qtvirtualkeyboard,qtwebchannel,qtwebsockets,qtwebview

>cmake --build . --parallel

You can see my source directory below.

Not source directory, "build directory". Build directory is the folder from which your calling configure and cmake.

@jsulm Hi,

you are right. But I used Src folder as Build directory in this case. In linux, the build directory was the path in where I call configure. But when I tried it in Windows, I couldn't achieve the same result, somehow all outputs are extracted to Src folder.

I tried it again. First, I create a build dir, and moved to this path in cmd, and then run configure, and I saw in output prints that build files are located to Src folder.

>Build files have been written to: C:/Qt/6.3.2/Src

and the files in build dir ;

qtbase, config.opt, config.opt.in

Which is bad. So in what directory are you exactly when you call configure? All the configure/build artefacts are in that directory.
And actually there is build.ninja file generated in the folder you're showing which means that you're using Ninja to build.

Definitely :)
Okay, I removed Src folder and reinstalled it via qt-maintenance tool. Then, I followed same steps again to configure & build. Now, I can see outputs in my Build dir as expected.
