C++ IDE seems to either be missing necessary standard files or can't see them since OS update to macOS from El Capitan.
Each of my C++ Applications has small '?' in each icon, and I get red error points everywhere starting from '#include' & 'using' calls at top of each main class. My only thinking is this is because of the OS upgrade, some special call to these files had issues, or they were somehow in a folder not accessible in this upgrade of the OS. I tried reinstalling 2 times, once with v8.1 and once with v.8.2RC, but all seem to unable to access these standard files. I hope this uprade doesn't kill this great IDE.
Nothing would change, but missing standard files is essential for IDE to properly compile.

It seem a root cause is the same as in the bug #268144.
Problem seemed to have resolved once I installed Xcode 8 and opened the developer app. It must have triggered the missing/hidden standard c/c++ file folder Netbeans could not find or install properly. I can't say hy or how this exactly resolved, but that after upgrading to macOS and Netbeans v8.1 noting not able to find folder with standard files (#include files or namespace file), the Xcode install and app opening (I am not sure if just the install triggered access to missing folder, or needing to start up the app too, so I suggest starting it up to be sure, or go step by step to see where the access for Netbeans is resolved).
Thanks for the information. And yes, installing XCode package installs some folders with headers. So it could be the reason
