including files from a C library [message #1822553]

I have little experience with Eclipse. I am specifically using Kinetis Design Studio version of Eclipse., on Window 10.

I'm trying to use a file "in" a library, fsl_clock_MK64F12.h. Highlighted here:
index.php/fa/37545/0/

I have linked to the library libksdk_platform.a successfully (see image below).
index.php/fa/37546/0/

I saw this [post](https://www.eclipse.org/forums/index.php/m/1765382/?srch=including+files+from+a+C+library#msg_1765382) on the forum, so I added the file path "C:\Freescale\KSDK_1.3.0\lib\ksdk_platform_lib\kds\K64F12" to the Preprocessor Includes Path and in all the Includes paths in the C/C++ Build/Settings Tool Settings tab.

But my includes statement in my source code results in "fsl_clock_MK64F12.h: No such file or directory". How do I include this file?

You have to tell two different things where your headers can be found:

the compiler via the makefile
the CDT Indexer

They are independent.

To do (1) Set the include path for each compiler at:
Project --> Properties --> C/C+ Build --> Settings --> Tool Settings tab --> <compiler> --> Includes
This only works when Eclipse is generating the Makefile.

To do (2) Set the include path as a User Entry at:
Project --> Properties --> C/C++ General --> Preprocessor Include Paths, Macros etc. --> Entries tab --> <language>

From your images, the include path for the clock header appears to be
<workspace dir>/ksdk_platform_lib_K64F12/platform/clock/system
Where: <workspace dir> is the absolute path to your workspace
You can use the workspace drop down (or button depending on which dialog) to select subdirectories in your workspace.

The library path appears to be:
<workspace dir>/ksdk_platform_lib_K64F12/debug

ksdk_platform_lib_K64F12 appears to be a project in your workspace.

As a side-note:
the second entry for lib searches starting with $(ProjDirPath)/Proj_Settings ...
doesn't contain a library from what I can see.
It doesn't hurt to keep it but it's useless and can be removed.
