Comment 2 Alexander Pepin 2010-12-22 15:41:50 UTC

This happens on any Windows system with both MSYS and cygwin.

Comment 3 Egor Ushakov 2010-12-22 20:34:38 UTC

standard output console type never worked on windows, see bug 148204, I will re-disable it in new infrastructure

Comment 4 Egor Ushakov 2010-12-22 21:33:43 UTC

not a regression

Comment 5 Egor Ushakov 2010-12-22 21:36:33 UTC

The problem here is that with msys on windows "internal terminal" is also not available (see bug 193241), so only external terminal really works for debugging.
But how to indicate that in GUI?

Comment 6 Alexander Pepin 2010-12-29 13:50:33 UTC

IT IS A REGRESSION! Previously a user can not only enter anything into Output window while debugging. Now it's impossible to debug any application using Standard Output.

Comment 7 Alexander Pepin 2010-12-29 13:54:20 UTC

Sorry for mistake "Previously a user could not..."

Comment 8 Egor Ushakov 2011-01-13 07:31:57 UTC

Comment 9 Egor Ushakov 2011-01-13 16:14:01 UTC

fixed in:
http://hg.netbeans.org/cnd-main/rev/0f2d8a39fa53
now on Windows Standard Output is switched to External Terminal and warning is shown to the user.

Comment 10 Quality Engineering 2011-01-14 06:08:17 UTC

Integrated into 'main-golden', will be available in build *201101140000* on http://bits.netbeans.org/dev/nightly/ (upload may still be in progress)
Changeset: http://hg.netbeans.org/main/rev/0f2d8a39fa53
User: Egor Ushakov <gorrus@netbeans.org>
Log: fixed #193740 (NPE in IOProxy$OutputReaderThread) - disabled standard output on windows (swithing to external terminal)

Comment 11 AlyonaStashkova 2011-02-11 21:46:28 UTC

Added to the Known Issues: C/C++ section of the NetBeans IDE 7.0 Beta 2 Release Notes as follows:

Issue #193740: On Windows platform, the "Use external terminal" warning displays when the Standard Output console is used for debugging.

    Description: The Standard Output console type is not used for debugging on Windows platform.

    Workaround: Use the Internal Terminal in the CYGWIN environment and the External Terminal in the MSYS environment instead.
