Be able to include files from folders

Hi. I have a project where I want to be able to include "hal/app_hal.h" from a folder called hal, but doing so gives an error. How do I fix it?

Please use the folder structure proposed by PlatformIO. That saves you from having to do manual build flags configurations / source filters:

github.com

platformio/platform-atmelavr/blob/develop/examples/arduino-blink/lib/README


This directory is intended for project specific (private) libraries.
PlatformIO will compile them to static libraries and link into executable file.

The source code of each library should be placed in a an own separate directory
("lib/your_library_name/[here are source files]").

For example, see a structure of the following two libraries `Foo` and `Bar`:

|--lib
|  |
|  |--Bar
|  |  |--docs
|  |  |--examples
|  |  |--src
|  |     |- Bar.c
|  |     |- Bar.h
|  |  |- library.json (optional, custom build options, etc) https://docs.platformio.org/page/librarymanager/config.html
|  |
|  |--Foo

hal looks like a library. So just put the hal/ folder inside lib/ and only #include <app_hal.>.
