    @J-Hilk Hi!

    It looks like you're right. My PATH variable is EMPTY, but I don't know why!

    However, I can compile with MSVC without problems! At any rate, I'll reinstall MSVC and see what happens.

    Thanks!

    alternatively, try removing the settings file of QtCreator,

    https://doc.qt.io/qtcreator/creator-quick-tour.html#location-of-settings-files

    I think that file is actually persistent and does not get automatically resolved with a reinstall

    or give it a (temporary) different location for the settings
    -settingspath <path>
    or
    -temporarycleansettings, -tcs

    if that fixes it, that the settings are at fault

      @J-Hilk OK, if reinstalling does not work, I'll remove the settings file for QtCreator.

      The question is: how will be these regenerated? Automatically when I start this app?

      Thanks!

        @bleriot13 on start of QtCreator

        see the command line option I added in my previous post

          seems like your path variable was messed up somehow. Maybe update of OS, MSVC ?

          I think you're using MSVC compiler? So reinstalling QtCreator should not make any differences.

          Maybe reinstall MSVC, Windows Kits, will fix this.

          Or you manually patch it in the project settings:

          @J-Hilk Hi.

          I don't know how did you get the window with that environment variables. Are the ones set by Windows? Or, on the contrary, these are handled by Qt? I mean: if I check my Windows variables I have no INCLUDE nor LIB variables... even after reinstalling MSVC, so I guess that these correspond to some option available in QtCreator. Can you tell me if I'm right and, if so, how to get to that window????

          I'm asking that because it seems that reinstalling (well, REPAIRING) MSVC does not work.

          Just one extra question: the command line switches you mention correspond to some tool,I guess. I assume that you mean that I should start qtcreator from the command line passin any of that arguments, is this so?

          Thanks you! Now I leave. No more interaction until tomorrow...

            You should run the Visual Studio Installer and do any updates that it thinks it needs to be done.

            By running cmd.exe and then:

            call "C:\Program Files (x86)\Microsoft Visual Studio\2022\BuildTools\VC\Auxiliary\Build\vcvars64.bat"
            

            (adjust to your local setup C:\Program Files (x86) -> C:\Program Files, and BuildTools -> Professional | Community | Enterprise)

            You will then get the environment where you can run the Visual C++ compilers - cl.exe.

            In my case it looks like:

            **********************************************************************
            ** Visual Studio 2022 Developer Command Prompt v17.6.0
            ** Copyright (c) 2022 Microsoft Corporation
            **********************************************************************
            [vcvarsall.bat] Environment initialized for: 'x64'
            

            With:

            set | findstr /i ^^INCLUDE=
            

            You can then see the paths that the compiler will look after files.

            Qt Creator when it registers the Visual C++ compilers runs the same vcvars64.bat to collect the environment variables.

            With Ctrl+Shift+F12 (Tools -> Debug Qt Creator -> Inspect C++ Code Model) you can have some information about what Qt Creator considers to be available.

            I have math.h under:

            "c:\Program Files (x86)\Windows Kits\10\Include\10.0.22000.0\ucrt\math.h" 
            

            and this path is part of the INCLUDE environment variable from above.

            On Windows setting up a working Visual C++ compiler can be a bit complicated. More than just unpacking an archive.

              @bleriot13 Often magic happens when Windows is rebooted.

                Hi once more.

                I'm on the verge of desperation.

                Following a mix of the advice given by all of you I have gone through the steps below:

                • Updated MSVC using the MSVC installer.
                • Uninstalled Qt completely.
                • Deleted the Qt settings in %appdata%\QtProject and %localappdata%\QtProject (not the contents of these folders but the folders themselves, so no trace of settings remained).
                • Removed all temporary files using Bleachbit.
                • Cleaned the registry using Glarysoft Registry Cleaner.
                • Restarted the computer.
                • Installed Qt from scratch.

                The problem persists.

                If I show the paths used by Qt using Tools -> Debug Qt Creator -> Inspect C++ Code Model I get the following:

                paths.png

                The red rectangle points to the paths that seem to indicate include directories. There, there's no trace of the actual path where one of the missing header files (math.h, for instance) is located:

                C:\Program Files (x86)\Windows Kits\10\Include\10.0.22000.0\ucrt

                a folder which is the same as the one given by cristian-adam.

                My last hope is to UNINSTALL everything (MSVC, Qt) and start again. This is what I'm going to do right now. If this doesn't work, I don't know what else can I do.

                  Big uff @bleriot13 ! It shouldn't be that hard to get a working MSVC installation.

                  Alternatively you could try a different way of installing Visual Studio, via a package manager (Chocolatey):

                  $ choco install visualstudio2022buildtools
                  $ choco install windows-sdk-11-version-22H2-all
                  

                  Then at the end I start the "Visual Studio Installer" from start menu and selected "Desktop Development with C++".

                  I only need Visual Studio BuildTools and not Community.

                    No joy.

                    This time I have uninstalled everything, cleaned preferences, registry and temporary files.

                    The result is exactly the same. However, there's something I have noticed that is related to the MSVC compiler.

                    If you open an "x64 Native Tools Command Prompt" using the MSVC 2022 entry in Windows Start menu, the vcvars64.bat batch file is automatically executed. Therefore, issuing the "SET" command lists the environment variables set in such a way that the compiler (cl.exe) may work properly.

                    Well, just after installing MSCV 2022 from scratch and before installing Qt, I opened the said command prompt and typed "set". The result is shown below:

                    If you take a look to the INCLUDE variable, you'll see that its contents is exactly the same that I presented in screenshot showing the "C++ Code Model Inspector - Qt Creator" a few posts before.

                    So, if MSCV 2022 does not include the complete list of include directories to look for when executing vcvars64.bat, Qt will never be able to learn where are they!!!

                    Obviously, after installing Qt I've got exactly the same results: the list of folders to look for headers is, once more, the one reported in the said image, so my code does not compile.

                    Curiously, compiling a simple C++ program using any of the offending headers (such as "math.h" or "string.h" using MSVC 2022 instead of Qt works without problems.

                    So, having arrived to this point, I'm afraid there is nothing else I can do to solve the problem. My only guess is that, maybe, it is possible, somehow, to add manually the missing paths to Qt creator, but a quick Google search seems to contradict me. The usual answer is "you can't add MSVC manually, it must be autodetected".

                    Any ideas from the experts?

                    Thanks.

                      Oh, my God.

                      I have installed MSVC 2022 in my wife's laptop, which has never seen a compiler in its life, and there the INCLUDE variable is perfect, listing all the necessary paths located in c:\Program Files (x86)\Windows Kits\10\Include\10.0.22000.0* (the ones my laptop does not have).

                      So, by some unknown reason, when I try to install MSVC 2022 in MY laptop, something goes wrong in spite of all the cleaning made.

                      I know that this goes beyond the scope of this forum but, any ideas about what to do so the MSVC 2022 installer thinks that it's working in a brand new computer, with no history behind that might lead to this undesirable problem???

                      Thanks.

                            @JonB Unfortunately, none of your two suggestions will work. First, programming is not exactly the kind of activity my wife would choose to make a living :-) so I discarded this solution immediately.

                            Concerning the second one, the INCLUDE variable is set by a chain of batch files, since QtCreator uses these to retrieve the value of this and others environment vars. Changing these batch files is firstly difficult and secondly undesirable, since any update of the underlying MSVC 2022 compiler will restore these.

                            At any rate, thanks for trying. I know that helping remotely is complicated.

                              @cristian-adam This is what I'm doing right now, but I have no faith on this working at all. I'm starting to consider reinstalling Windows... :-(

                                If you don't want to change the supplied MSVC batch files, you can always e.g. simply add an extra batch file which is invoked after them and alters/adds to INCLUDE variable. Just saying.

                                  Re-installing Windows from time to time is a good idea. Forces you to think about things, where to store information, how to backup etc.

                                  You could try two things:

                                  1. Open Qt Creator from a Visual Studio Command Prompt, where I assume that the INCLUDE, LIB and PATH environment variables contain the necessary paths needed to compile the project.
                                    With set INCLUDE=%INCLUDE% paths could be prepended or appended.

                                  2. If Qt Creator works fine, one could then add in the Qt Creator's Preferences -> Environment -> System -> Environment the INCLUDE, LIB, and PATH values.

                                  They would be global, affect all kits, but hopefully work as expected.

                                  PATH=${PATH};\some\extrapath is the format of Qt Creator's macro expansion.

                                    @cristian-adam This is a very good suggestion. In fact, in one of my previous posts I was asking where these variables could be set.

                                    At any rate, it is much more than just probable that I will reinstall Windows. If things start to fail like in this case, I think it's time to reset the system.

                                    Thanks!

                                      Well, reinstalling Windows did the trick. Now everything works as it always did.

                                      A pity that posting in MS Visual Studio help forum takes about two weeks to get an answer. Or at least, this is what the bot that first answers you says.

                                      Two weeks, yes.

                                      Thanks to all of you.
