The preLaunchTask 'C/C++: g++.exe build ative file'terminated with exit code -1.

I keep running into this problem I made sure I have the right path. I have switched from Windows power shell to command prompt and still not working, reinstalled msys2,

• Executing task: C/C++: g++.exe build active file

Starting build...
cmd /c chcp 65001>nul && C:\msys64\ucrt64\bin\g++.exe -fdiagnostics-color=always -g C:\test\test3\main.cpp -o C:\test\test3\main.exe

Build finished with error(s).

• The terminal process failed to launch (exit code: -1).
• Terminal will be reused by tasks, press any key to close it.

Sometimes the build fails because the compiler path has not been added to the %PATH% environment variable. If that's the case, you can try setting 'cwd' in your task to "C:\\msys64\\ucrt64\\bin"

So it looks like the exe doesn't run on the terminal. Which version of the compiler do you have?

I'm sorry, at this point I'm out of ideas. We don't own msys64. You might need to engage with the support team for the compiler since it's not building runnable programs for you.

Thank you for your help. Ended up finding a fix by changing my launch.json and adding -static in the args in the task.json
