while compiling the file 1_10_1_Calibration_Sketch.ino (module_1) I get the error :
” d:Arduinolibrarieslvglsrcexamplesstyleslv_example_style_14.c:1:10: fatal error: .. /../src/themes/lv_theme_private.h: No such file or directory
1 | #include “.. /.. /src/themes/lv_theme_private.h”
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
compilation terminated.
exit status 1
Compilation error: exit status 1 “
I think I have arranged the folders as indicated. I note that I work on PC (win10) with disk D:
What could it be?
Thanks for a tip

Hi.
what version of the ebook are you following? 
The latest version is 1.4. Make sure that’s the version you’re following at the moment.
 
when setting up the lvgl library, don’t move the demos folder.

Hi
I use the book with the last version 1.4
I noticed that in the course guidelines v. 1.4 the library “ESP32 Core by Espressif Systems version 3.0.4” is requested but that in the “library Manager” is not present !!What could it be?
I still note that the “libraries” folder is located on D:Arduinolibraries and not on C:
Could this be a problem?
Thanks for a tip

Where exactly they should
find the “Demos” and “Examples” folders?

Hi.
The ESP32 version is not in the library Manager.
It is on the Boards Manager.
 
Our Arduino installation is on the C driver, but yours might be on a different place. That’s why you need to follow your sketchbook location.
 
As for the LVGL library, is this the first time installing it? Or have you previously installed it?
 
Please unninstall the LVGL library and follow the installing procedure steo-by-step exactly as shown in the eBook.
Move copy lv_conf.h configuration file to Arduino libraries folder Arduino IDE 2
 
That compilation issue is because the demos and examples folder are not in the original place (probably because you’re using a previous installation).
 
Regards,
Sara
