Description ilia 2017-06-27 10:24:56 UTC 
Bug for issues in NativeExecution that appear when user have no MinGW nor Cygwin installed. And for issues that appear when cygwin/mingw path differs from a default one.
Comment 1 ilia 2017-06-27 10:28:12 UTC 
When trying to debug I'm getting redirected to Toolchain Options. That's good.
But when trying to attach I get "failed to parse output of ps" message and

stack. Maybe it's OK.
Comment 2 ilia 2017-06-27 10:31:01 UTC 
1) Launching NetBeans with no cygwin/mingw installed
2) Install cygwin (well, or just move from ___cygwin64 to cygwin64)
3) Everything in nativeexecution behaves like it's not installed (because WindowsSupport has "initialized" flag and want try to re-read settings anymore).

We should trigger re-initializing of WindowsSupport after toolchain was changed...
Comment 3 ilia 2017-06-28 08:29:07 UTC 
When first launched Terminal doesn't give any warning. All subsequent Terminals give a warning. Is this intended?
Comment 4 ilia 2017-06-28 08:42:55 UTC 
situation in #comment 3 happens because we are in silent mode.
Comment 5 ilia 2017-06-28 09:36:19 UTC 
Solution is to print 'no cygwin' message in a Termainl when invoking the Terminal.

Integrated into 'main-silver', will be available in build *201707201608* on http://bits.netbeans.org/dev/nightly/ (upload may still be in progress)
