The C++ Compiler cannot run a simple test program

As an alternative, you could open a cmd.exe and this time trying it out with Visual C++.

For this you need to to have Qt for MSVC installed at c:\Qt\6.5.0\msvc2019_64.

Then:

set PATH=C:/Qt/Tools/CMake_64/bin;C:/Qt/6.5.0/msvc2019_64/bin;%PATH%
$ cmake -S . -B build -DCMAKE_PREFIX_PATH=C:/Qt/6.5.0/msvc2019_64 
$ cmake --build build --config Release

This time no -G was passed, CMake will pick up the Visual Studio generator using msbuild.

If this works, then you'll have to change the Generator in Qt Creator's Kits configuration for the Visual C++ kit.

Edit: new cmd.exe window, so that no MinGW bits are preset in the PATH variable, CMake should pick cl.exe as before when it complained about the missing QT package.

about the Visual Studio thing I also tried using the Qt extension in Visual Studio but when I tried to create a new Qt Widget Application it shows this

cristian-adam

@Daemonitas Since I'm the maintainer of the CMake bits in Qt Creator I can't say much about the Visual Studio Qt plugin. A different colleague is responsible.

Since the Visual Studio experiment from a few posts passed the ABI check, it means that at least that generator works.

If you modify the generator to "Visual Studio" in the Qt 6.5.0 MSVC Kit like this:

You should be able to to finally compile your application.

Here is the result in the "General Messages" tab

Since you have changed the generator in the Kit you would have to click in the Project settings on the "Re-configure with Initial Parameters" or just create a new project using this Kit.

The new project will get the right generator and should configure just fine 🙂

it somehow worked (?) in a way

it enables the build and run button but at the same time it can't build when i'm using the minGw kit but when I use the MSVC kit it shows a ton of errors

as shown here

Edit:

this is the output on the MinGW kit

cristian-adam

A MSVC Kit works with these generators:

Ninja
Visual Studio 17 2022
NMake Makefiles
NMake Makefiles - JOM

The MinGW Kit would work with these generators:

Ninja
MinGW Makefiles

You can't have a MinGW Kit working with a Visual Studio generator.

There is something broken on your PC. I'm running out of ideas.

@cristian-adam
for the msvc kit it seems the error to be in just one line
" <Exec Command="%(PreBuildEvent.Command)$(_BuildSuffix)" StdOutEncoding="%(PreBuildEvent.StdOutEncoding)" StdErrEncoding="%(PreBuildEvent.StdErrEncoding)" Condition="'%(PreBuildEvent.Command)' != ''"/>"

If nothing works Ig I cant use Qt then

Edit:
i tried changing the generator to MinGW Makefiles in the MinGw kit and get this error

You should check your global PATH environment variable.

At https://github.com/isl-org/Open3D/issues/2316 it's being mentioned:

Error MSB3073 is generally caused by an incorrect path in the command line

You can type in Qt Creator in the Locator field (press Ctrl+K):

! cmd /c set PATH

In the General Messages pane you should get the output. Maybe you can paste it here.

This could explain why so many command line tools are broken.

On this Arm64 Laptop I have something like:

Starting command "cmd /c set PATH".
Path=C:\Projects\github\vcpkg;C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOWS\System32\Wbem;C:\WINDOWS\System32\WindowsPowerShell\v1.0\;C:\WINDOWS\System32\OpenSSH\;C:\ProgramData\chocolatey\bin;C:\Program Files\Git\cmd;C:\Users\Cristian\AppData\Local\Programs\Python\Python311-arm64\Scripts\;C:\Users\Cristian\AppData\Local\Programs\Python\Python311-arm64\;C:\Users\Cristian\AppData\Local\Microsoft\WindowsApps;C:\Users\Cristian\AppData\Local\Microsoft\WinGet\Links;c:\Tools\cmake\bin;c:\Tools\ninja;c:\Tools\ccache;;C:\Users\Cristian\AppData\Local\Programs\Microsoft VS Code\bin;C:\Users\Cristian\AppData\Local\Microsoft\WinGet\Packages\Microsoft.Sysinternals.ProcessExplorer_Microsoft.Winget.Source_8wekyb3d8bbwe;
PATHEXT=.COM;.EXE;.BAT;.CMD;.VBS;.VBE;.JS;.JSE;.WSF;.WSH;.MSC

The command "cmd /c set PATH" finished successfully.

And for me all the things just work. Qt 6.5.0 with MSVC and MinGW.

I can't see anything that would break things 😔

How does the MSVC Kit with NMake Makefiles JOM generator work?

Daemonitas

@cristian-adam
the build button was disabled again

oops I accidentally marked it as solved

goldenhawking

QMake sometimes is simpler than CMake for simple applications.

Daemonitas

@Daemonitas

I got this pop up now when compiling using the msvc kit

Orkun Tokdemir

@Daemonitas Can you compile anything with the compiler CMake found?
Can you please try it with the hello word code?

<the full path I highlighted>  hello.cpp -o hello

Daemonitas

@Orkun-Tokdemir
you mean this one?

Orkun Tokdemir

@Daemonitas yes

Daemonitas

@Orkun-Tokdemir
well clearly it works
perhaps the problem is actually my laptop itself
but what causes this in the first place

Orkun Tokdemir

@Daemonitas Did you run it as below?

"C:Qt/Tools/mingw120_64/bin/c++.exe"  hello.cpp -o hello
