If you've tried to run Windows console programs (such as pdcurses based applications) using a terminal emulator (rxvt, mintty) via msys (including msys2), you'll probably have I/O issues. Output may not appear properly on the screen.

There are two work-arounds for the issue.

1. Use software from a project that deals with console/terminal incompatibilities.

Winpty - provides and interface similar to a Unix pty-master for communicating with Windows console programs.

Alternative to MinGW and Cygwin and build scripts for various Open Source tools:

2. Run the program in a console instead of a terminal.

I have an article on setting up msys to work with the standard Windows console instead of a terminal at:
http://www.distasis.com/cpp/msys.htm

For alternatives to the standard Windows console, take a look at these projects.

ConEmu Console emulator - Unlike Console 2, this has a build file for gcc.

Console 2 - Command prompt replacement. May be used with cmd.exe or rxvt or other shells.

ConsoleZ - Console 2 fork with improved support for Windows Vista/7/8/10.
