Hello, I have a doubt very basic.I can not do basic includes as conacts.h or calendar.h order to use the functions of these APIs.
For example:
I create any project, however when I try to insert an include in the header of a file or .cpp .h it displays the error:
"Multiple markers at this line
- Fatal error: 'calendar.h' file
not found
- Unresolved inclusion:
<calendar.h> "
Note: sorry, my very basic is English.
