I don't know what the problem is, I get no errors.
Please make the "Build output " window bigger so that I can see all the compilation messages.

Have you been able to compile any version of the project with any
version of Keil?

Change the mobile number as [number removed] in the program. Compile it and send me the program and hex file also.

The compiler thinks the micro doesn't have enough memory.
You probably selected an 8051.

Change the selected device.

Go into "Project " then "Select Device for target"

Select the AT89C55

If that works, try changing to AT89C52.

Code for the AT89C55 will be okay for this project.

Check your messages, I sent you some files.

Pins high is the normal state. You need a program to set them low
