#include "src/MeSingleLineFollower.h"
#include "src/MeCollisionSensor.h"
#include "src/MeBarrierSensor.h"
#include "src/MeNewRGBLed.h"

Where exactly are these libraries located in relation to the sketch file ?

twade · April 24, 2024, 8:39pm

The libraries are relative to the folder that the sketch file is in.

b707 · April 24, 2024, 8:43pm

You can't use a source code directories inside the sketch folder.
You have either copy these files to the sketch folder itself or put it in standard Arduino library.

UKHeliBob · April 24, 2024, 8:55pm

As a matter of fact you can

For complete clarity, what is the full path to the sketch .ino file and the full path to MeSingleLineFollower.h ?

twade · April 24, 2024, 9:05pm

Full path is: Arduino > libraries > Crab Walk > The_crab_walk

UKHeliBob · April 24, 2024, 9:08pm

Full path of what ?

twade · April 26, 2024, 8:29pm

full path to the MeSingleLineFollower.h

twade · April 26, 2024, 8:31pm

The full path for the sketch.ino file is the same path, because for both once you're in The_crab_walk you can then access the files

b707 · April 26, 2024, 8:37pm

Please be more accurate when presenting a path. Does your path contains a ">" characters?

If suppose that the path is something like
Arduino/libraries/Crab Walk/The_crab_walk

I see a several problems in it

the library name can't contain a spaces
the library code must be either in the first level folder or in src folder. The folder name The_crab_walk is invalid name for this.

b707 · April 26, 2024, 8:42pm

So why did you included it in the code as

where the src/ in your path?

twade · April 26, 2024, 8:55pm

I moved it to Arduino/libraries/src/MeSingleLineFollower.h(plus the rest)

b707 · April 26, 2024, 8:59pm

It is incorrect path too.
The file should be in the folder, for example:
Arduino/libraries/CrabWalk/MeSingleLineFollower.h

and the includes in the code shouldn't have a "src" part at the beginning

Also the sketch itself must be moved to sketch folder from the library.

(edited - remove the src part from the path)
