How to edit built-in include paths? [message #1748725] Mon, 28 November 2016 00:03 Go to next message

This is for Eclipse on macOS (and is also true of older versions of OS X).

Every time Apple upgrades the OS and releases a new version of Xcode, I get warning messages referring to Xcode content. For example, when macOS 10.12 replace OS X 10.11 this appeared:

Invalid project path: Include path not found (/Applications/

I can add the path for the includes for the library in the new version of Xcode but I can't get rid of the old path as it is "built-in" and not editable at:

Project > Properties > C/C++ General > Paths and Symbols > Includes (tab)

Does anyone know how I get rid of these warning permanently without creating a new project and moving all the source files across?

I had this problem long ago when I switched to a newer version of GCC.

You should be able to go to Project --> Properties --> C/C++ General --> Preprocessor Include Paths, Macros etc.
Select the builtin values on the Entries tab
Push Clear Entries
You need to do this for each compiler.

Collecting the current builtins should happen on the next build
But if needed, go to the Providers tab.
Select the proper builtin provider
Then press Apply

If you have Project --> Properties --> C/C++ Build --> Discovery Options,
you may need to clear the discovered entries for each compiler and configuration.
While you are there, disable auto discovery if necessary.
That's now controlled by Preprocessor Include Paths, Macros etc.
