[LVGL] Generated image c file must use project defined Build - Include parameter

[drik]

Describe the bug
When I define LVGL Include parameter in my project, EEZ still generate c file with lvgl/lvgl.h

To Reproduce
Steps to reproduce the behavior:

1. Go to Project Settings --> Build --> LVGL Include (change tthe default 'lvgl/lvgl.h' by 'lvgl.h'
2. Add an image (named xxx) to your project and Build
3. Open the generated ui_image_xxx with a text editor
4. On line 7, you can see #include "lvgl/lvgl.h"

Expected behavior
The build system must use LVGL Include parameter to generate ui_images

Desktop (please complete the following information):

• OS: Windows
• Version: 11

LVGL version (if used)

• 9.x

We are using LVGL tool to generate these image files and doesn't change them afterwards. If you look closely you can see that following is generated:

#ifdef LV_LVGL_H_INCLUDE_SIMPLE
#include "lvgl.h"
#else
#include "lvgl/lvgl.h"
#endif

So, you can add preprocessor definition LV_LVGL_H_INCLUDE_SIMPLE and lvgl.h will be included.

i had to ask because i have the same problem, where to make this definition of LV_LVGL_H_INCLUDE_SIMPLE?
For now i'm editing every image_xx.c file to include the "lvgl.h" and not "lvgl/lvgl.h"
Sorry if my question is noob. thx in advance.

where to make this definition of LV_LVGL_H_INCLUDE_SIMPLE

Are you on Arduino?

[petrubuciu]

yes, ESP32 s3

I think you can't add preprocessor definitions using Arduino IDE.

So, I decided to prepend each generated img_xxx.c file with the following:

#ifdef __has_include
    #if __has_include("lvgl.h")
        #ifndef LV_LVGL_H_INCLUDE_SIMPLE
            #define LV_LVGL_H_INCLUDE_SIMPLE
        #endif
    #endif
#endif

This should fix the issue for Arduino.

Implemented as described in my previous comment.
