Is there a different way to build GNU softwares for windows. because i also build "GNU make"​ but it's also same as "GNU grep​". if there's a better way which you guys recommend you can share it with me.

WSL 2 should be much less painful.

With MSYS2 you have several options and could try some of the other 
options. Again, I'm the wrong person to ask about this. You'll need some 
expertise in these systems to use any of them.

Can you run grep.exe in the Visual Studio debugger? Then you should be
able to see what is happening more clearly. For example, does it go into
main()?, does it parse command line arguments?, etc.

Another obvious thing to check first is whether a simple "hello world"
program shows any output. If that is not working, there is something
wrong with your MSYS development environment.
