Description
Hello there, I’m new to LVGL 
and I use the Visual studio simulator on Windows for the projects. The issue I’m facing now is that there are some functions or arguments not appearing in the lvgl liberary even though they are available on the other platforms (Mac and Linux) according to the explanations in the website.
Also these functions should be there according to the documenttion of LVGL website.
Examples of functios:
lv_page_create();
lv_cont_create();
lv_obj_set_auto_realign();
and other functions that relates to the layouts and screens and Auto-fitting.
So what could be causing this issue? 
and thank you very much 
What MCU/Processor/Board and compiler are you using?
I’m using the widows simulator for now.
What do you want to achieve?
To use some functions that seems not working.
What have you tried so far?
I went through the simulator and example files that are ptovided by LVGL but I didn’t find the cause of the issue.
Screenshot and/or video
As you can see in the screenshot, the functions with red underlines are supposed to be there but I cannot use them and they are not appearing anywhere
