Project type as LVGL(No EEZ Flow).

When using a widget LV_ROLLER and assigning variable to the options an error occurs during compilation of project.

../Drivers/STM32/GUI/src/ui/screens.c:2870:9: warning: implicit declaration of function 'compareRollerOptions' [-Wimplicit-function-declaration]
 2870 |     if (compareRollerOptions((lv_roller_t*) objects.roller_select_ils, new_val, cur_val, LV_ROLLER_MODE_NORMAL) != 0) {
      |         ^~~~~~~~~~~~~~~~~~~~


c:/program files (x86)/gnu arm embedded toolchain/10 2021.10/bin/../lib/gcc/arm-none-eabi/10.3.1/../../../../arm-none-eabi/bin/ld.exe: ./Drivers/STM32/GUI/src/ui/screens.o: in function `tick_screen_ils_selection':
D:\Projectos\***\***\****\Debug-STM32/../Drivers/STM32/GUI/src/ui/screens.c:2870: undefined reference to `compareRollerOptions'

The function is not part of LVGL (at least don't find anything as compareRollerOptions

As a quick workaroud, change the definition of screens.c to:

#include <string.h>

#include "screens.h"
#include "images.h"
#include "fonts.h"
#include "actions.h"
#include "vars.h"
#include "styles.h"
#include "ui.h"

static int32_t compareRollerOptions(lv_roller_t *roller, const char *new_val, const char *cur_val, lv_roller_mode_t mode) {
        return strcmp(new_val, cur_val) != 0;
}

//${eez-studio LVGL_SCREENS_DEF}
//${eez-studio LVGL_SCREENS_DEF_EXT}

int eez_flow_get_selected_theme_index() { return 0; }
