The C++ Compiler cannot run a simple test program

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?

@cristian-adam
the build button was disabled again

oops I accidentally marked it as solved

QMake sometimes is simpler than CMake for simple applications.

@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

Daemonitas

@Orkun-Tokdemir
yes It works fine

There is something wrong with your Windows installation / laptop.

The compilers themselves seem to work, but not the build programs (ninja, mingw32-make, msbuild, jom).

The antivirus is not the issue. I can think of two issues:

some sort of a disk failure
some user rights access issues

You can get yourself a Windows Virtual Machine from https://developer.microsoft.com/en-us/windows/downloads/virtual-machines/

That is if the laptop is powerful enough to run a VM.

@cristian-adam
so I reinstalled windows and mingw works

msvc said its missing cxx compiler path but hey atleast mingw works so I guess problem solved
my windows is the problem after all. Had to sacrifice my files but as long as it works its a win in my book.
