Dear, I defined Port1 pins as in attached overlay file. The binding of pins is done as in lcd.h attached file. When, build is started, the error written in title is displayed and build failed. Please guide, how to fix this issue.

Hi Gulzar,
Could you kindly change the "tasks" option in the output to "output" and share the messages that appear there?
