Arduino compiler

Regarding a project with Squareline, I am following the instructions exactly, however, the arduino simply cannot compile, even when logged in. I tested it with the ‘smart gadget’ demo project and it worked. Here’s what pops up on the screen when compiling.

ui_helpers.h:23:32: error: unknown type name ‘lv_obj_t’
void _ui_dropdown_set_property(lv_obj_t * target, int id, int val);
^

ui_helpers.h:26:29: error: unknown type name ‘lv_obj_t’
void _ui_image_set_property(lv_obj_t * target, int id, uint8_t * val);
^

ui_helpers.h:26:56: error: unknown type name ‘uint8_t’
void _ui_image_set_property(lv_obj_t * target, int id, uint8_t * val);

Other error messages are similar.

Please add the whole compiler log.

Thanks for answering. I tried to find the log file but I couldn’t. Do you know which folder it is located in?

I mean the compiler log of Arduino that you see at the bottom of the window with orange letters.
