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?

Dear Priyanka, I am just new to Nordic. Please, give example to include overlay, .h and .c files in CMakeLists.txt ..I tried that way also, the error is shown in atached image. The CMakeLists.txt also shown on roght side in the image.
Hi PY, I have done all the changes. The erros and warinings are shown in attached iamge. The project Zip file also attached. I am using SES and nRF1.71.
