Environment:

IDF 5.0.2

idf_components.yml

dependencies:
  espressif/freetype: "*"
  lvgl/lvgl: "~8.2.0"

LVGL Configuration: -- to set LV_USE_FREETYPE

idf.py menuconfig to select FreeType library in menu Component config -> LVGL Configuration -> 3rd Party Libraries

Compilation result: -- lvgl cannot found ft2build.h

managed_components/lvgl__lvgl/src/extra/libs/freetype/lv_freetype.c:12:10: fatal error: ft2build.h: No such file or directory
12 | #include "ft2build.h"

Question: Could someone tell me how to solve the issue? What I forgot to do or what I misunderstood with managed components?

Hi. To do that you can link FreeType to LVGL in your CMakeLists.txt like so:

Code: Select all

idf_component_get_property(lvgl_lib lvgl__lvgl COMPONENT_LIB)
idf_component_get_property(freetype_lib espressif__freetype COMPONENT_LIB)
target_link_libraries(${lvgl_lib} PUBLIC ${freetype_lib})
