I posted the following to the Discussion tab. I thought it would be best
to also post to the email list, in case someone looks here.
------------------------
I wanted to thank Greg Jung for sending a very helpful response. It
might benefit some others.
Run "C:\msys64\usr\bin\bash.exe --login -i" from within the windows 7
command prompt ("dos shell") and get a bash prompt. Then run the curses
(compiled with pdcurses) program with "./txu1-tpl-eg1.exe" - it runs
perfectly! Arrow keys work, everything looks / functions perfectly.
Next, make a copy of the command prompt desktop icon, change the target
to the command line given above, it works perfectly.
------------------------
I'm still confused about the difference between 1) mintty, 2) winpty
from within mintty, 3) bash.exe from within dos window, and 4) dos
window itself. For example, I notice that mc runs poorly under the
bash.exe environment. Arrow keys don't work, colors get messed up, it is
slow. Oddly, mc (same exe) runs perfectly when run directly from dos shell.
Obviously, I don't really understand what's going on. It would be nice
if someone who understands more about this could post some advice,
related to different options for compiling and running curses
applications under msys2.
Anyway, at least the bash.exe option is good progress.
