Include files problem

I have a stepper.cpp file and I want to call some functions which exist in linkedList.cpp which also has a header file linkedList.h

so in PIO.ini (for the stepper project) I included the lib_extra_dirs line as below (directory copied from Windows explorer), but the code won’t complile, it doesn’t seem to find the .h file

should I do this a different way perhaps?

thanks for help.

Compiler output extract:

src\Stepper.cpp:31:10: fatal error: linkedList.h: No such file or directory
Compiling .pio\build\ATmega4809\FrameworkArduino\Tone.cpp.o

* Looking for linkedList.h dependency? Check our library registry!

It looks like you’ve pointed lib_extra_dirs directly into the include folder of the library. That’s wrong when using that directive – as the documentation says

This is a not direct path to a library with source code. It should be a path to storage that contains libraries grouped by folders. For example, D:\PlatformIO\extra\libraries but not D:\PlatformIO\extra\libraries\FooLibrary.

So you should try to add the Development folder to the lib_extra_dirs so that the LDF finds the usage of the Circular-Linked-List library (this shows up in the dependency graph too).

lib_extra_dirs = 

ah thanks, I should’ve read the stuff first :frowning: I’ll give it a try.
