A lot of errors 'was not declared in this scope' (Read 227 times)

Vosreinard Newbies Offline Posts: 6	A lot of errors 'was not declared in this scope' Sep 8^th, 2019 at 10:31pm Hi, In my Rotary Table Project I use two sets .cpp & header files: Wstepper and Wcld. I get errors in Wstepper.cpp an Wcld.cpp saying about a lot of variables, included over ARDUINO.h, that they are not declared. What can be mitigated?

Ensure the include paths for your header files includes the relative path, like below:

#include "src/Wlcd/Wlcd.h"
#include "src/Wstepper/Wstepper.h"

This should resolve the initial errors, and this also detailed on the below page:

Dear Simon,
Thanks for your reply. Helas Embarrassed

, when applying #include "src/Wcld/Wcld.h" instead of #include "Wlcd.h" the program will be thrown back to the situation I had before I posted my previous question "Source file cannot find header file" with answer from Tom Leek. https://www.visualmicro.com/forums/YaBB.pl?num=1567802164/1#1 .
The problem is as follows: EEPROM.h can be found but not the underlaying functions, etcetera.
again: What can be done to resolve those problems?

Then you will see that you have not included the src sources codes in your project. Right click them and click "Include in project", then the red warning indicator will be removed.

https://www.visualmicro.com/public_html/yabbfiles/Smilies/dankk2.gif Yes I did without a positive result.https://www.visualmicro.com/public_html/yabbfiles/Templates/Forum/default/cry.gi...
In Solutions Explorer I have included RotaryTable.log . Maybe this will be useful.

Thise errrors are visual studio trying to make a build and idicates some unexpected errors. Visual Micro has given up trying to compile or things that it does not have too.

I just compiled your project okay but I had to add

#include <Arduino.h>

and change
#include <Wstepper.h>

to
#include "Wstepper.h"

I notice you have used a couple of arduino from the web. You should not try to compile arduino libraries from within your project code most are not designed for that.

You should make your project work in the arduino ide so you can understand how arduino works. Then if you want local library sources you can use the options on the Add Library menu in visual micro which will create a local copy.

The ideal would be

SolutionFolder
   Libraries
      Library1
   Projects
      Project1

But intiially place libraries in mydocument\arduino\libraries because both visual micro and arduino will consider that valid.

The error you have posted is from the visual studio output window when set to build. Visual Micro adds Micro Build output window with its own reporting.

tip: If the project name, project folder name and an .ino name are all the same then visual micro will consider the project an arduino project and manage it for you.
