> I’m using SCons to build an Arm Cortex-M7 project based on GNU Arm
> Embedded Toolchain.
> Other than compiling the project, I’d like to generate the list of symbols
> to import from my IDE to get an accurate code highlighting.
> I wrote some code to generate the list of header files included in the
> projects, then I’m trying to get the symbol form every header file.
> The main issue I’m facing is that the include hierarchy is not preserved,
> so for example I got errors from freertos because FreeRTOS.h must appear in
> source files before include task.h.
> Does anybody know how to fix this problem or a different method to
