Closing -- the 2.2.x series is no longer supported.

I have tested with nano v2.25 both outside and inside an uptodate cygwin install - I neo longer get this warning message.

TERM is not set in the environment outside of cygwin.

As mentioned in bug #35214, it might help to set %TERM% to "cygwin". Can you confirm?

For others like me using mintty and reaching here via Google:

If you are using nano under the Git For Windows environment and mintty, you will get this redirection error. mintty is not a proper tty, and implements stdin/out with pipes (which I assume causes this issue) - see http://jpsoft.com/blogs/2012/03/windows-console-replacements-part-1-take-command-and-mintty/

i was able to compile 2.2.6 with ncurses-5.7.18 and gcc-3.3.4 under cygwin. the build runs with no problem... apparently this gives a clue that the 'redirection is not supported' issue is probably coming from pdcurses.

here is the 2.2.6 package:

i've repacked gnu-nano-2.2.5 from cygwin (dll 1.7.7-1)


the version from cygwin runs ok on this machine.
more information in README.txt

gave it a try on another machine with windows vista sp1 and it seems to work there.

bellow is some disassembly debug for the latest nano-2.2.6-win32.

any idea what the cause for this might be ?
