cannot compile with minimal setup from readme

[jappyjan]

I am using the platformio.ini from the readme and have a basic lv_conf.h in the include folder

this is my platformio.ini

[platformio]
#default_envs = esp32-2432S028R

[env]
platform = espressif32
framework = arduino

monitor_speed = 115200
monitor_rts = 0
monitor_dtr = 0
monitor_filters = esp32_exception_decoder

# Partition scheme for OTA
board_build.partitions = min_spiffs.csv

build_flags =
    -Ofast
    #-Wall
    -D CORE_DEBUG_LEVEL=ARDUHAL_LOG_LEVEL_VERBOSE
    # LVGL settings
    -D LV_CONF_PATH="/Users/jappy/code/cyd-lvgl-test/include/lv_conf.h"

lib_deps =
    https://github.com/rzeldent/esp32-smartdisplay.git

[env:esp32-2432S028R]
board = esp32-2432S028R

this is my lv_conf.h

#define LV_COLOR_DEPTH 16

// debug only
#define LV_USE_PERF_MONITOR 1
#define LV_USE_MEM_MONITOR 1

/*Enable the lvgl log module*/
#define LV_USE_LOG 1

i cannot get past this error message during compilation.

@jappyjan, it looks like your LV_CONF_PATH is incorrect. Try switching out your definition in platform.ini to look like this:

build_flags = '-D LV_CONF_PATH="${platformio.include_dir}/lv_conf.h"'

This way the path comes directly from the platformIO.
Hopefully this helps.
