How to correctly write the path to the header file in the directive in Eclipse?

Question

Eclipse

Good afternoon.
Some header files have a directive that must contain the path to the header file with the choice of the iar/gnu compiler.
What is the correct path to this file?
The definition of the directive was added to C/C++ general -> path and symbols -> symbols
symbol (directive) value("gnu.h")
before the definition of the directive, the folder with gnu.h was added to inlcude.
When you open project files that contain a directive with gnu.h, you can see that the directive has taken a value and you can open this header file.
But when compiling, arm-none-eaby gives an error
/gnu arm eclipse/build tools/2.6-201507152002/bin/sh: can't open gnu.h: no such
file
${workspace_loc:/${ProjName}/compiler/gnu.h}
With this declaration, the directive was not defined at all.
Can anyone tell me how to correctly write the path to the file in the directive?

Answer 1

You will have to answer yourself,
Add the folder with gnu.h to inlcude C/C++ general -> path and symbols -> includes for gnu C and gnu C++
In C/C++ general -> path and symbols -> symbols add
symbol (directive) value(<gnu.h>)
