PSPad + MSYS2

After installing the program MSYS2, in the console window the command:

g++ hello.cpp -o hello

after execution creates file hello.exe
But, in PSPad Settings -> Highlighters Settings:

"C:\msys64\ucrt64\bin\g++.exe" "%File%" " -o hello"

after execution not creates file hello.exe
What do I need to change to get my hello.exe? It would be very convenient and fast.

remove last quotes, -o and result file name shouldn't be in quotes or enclode file name only, like this:
"C:\msys64\ucrt64\bin\g++.exe" "%File%" -o "hello"

Test your command line in Windows CMD (command interpreter)

I tried rewriting the settings in different ways.
This should work:

"C:\msys64\ucrt64\bin\g++.exe" "%File%"

but it doesn't exe. There may be a discrepancy between these two programs. But it doesn’t matter, it’s quite enough to write the code in the editor and compile it separately. It's not critical, and I can work with this.

When you run it in CMD intepreter (Windows command line window), does it work?

Yes, it works in command line.

I cleaned my disk, cleaned the Path, reinstalled MSYS2,
and now F9 works very well.
This was probably necessary and useful.

Sounds like you are constructing an IDE with the old Borland look and feel. I have a huge appreciation for Turbo Pascal, so I am interested if my suspicion is right and if affirmative how far you've got.
