Compile error

[martin072]

Hi,

I am new to the display, was trying to compile your library, but it fails with the following error. Any idea?

.pio/build/esp32dev/src/main.cpp.o:(.literal._Z10mainscreenv+0x8): undefined reference to `lv_font_montserrat_22'
collect2: error: ld returned 1 exit status
*** [.pio/build/esp32dev/firmware.elf] Error 1

Hi Martin,

You have to include the font in lv_conf.h.

Change the line
#define LV_FONT_MONTSERRAT_22 0
to
#define LV_FONT_MONTSERRAT_22 1

Regards

Yup, that was already done.. still an error:

Hi Martin,

What lv_conf are you updating? Have you defined the include path in platformio.ini?

# LVGL settings
-D LV_CONF_PATH="${platformio.include_dir}/lv_conf.h"

[martin072]

Hi Yes,

Well as follows:

-D LV_CONF_PATH="lv_conf.h"

its in the same dir. as main.cpp also there is no error about the lv_conf.h..

I suggest to make the path absolute

[martin072]

Thanks, that did the trick.

i think i solved the problem, finally realize the real lv_conf.h is on include folder..
thanks & sorry
