"Wrong lvgl version" compile error (v8.0)


I upgraded from v7.10.1 to v8.0 and compiled it, but the below error occurred. What should I do?

What LVGL version are you using?


You need to update lv_examples as well.

I did that all of lvgl v7 files are replaced with v8 and sample folder set to ‘exclude from build’. But the sample folder is not excluded from build after build. I don’t know why it doesn’t work.
Anyway I deleted the sample folder from project then builded successfully.
