Identifiers in the .icf file is undefined in IAR

[Aatif Shaikh1]

I'm working on a project, which is built on the IAR workbench 7.50 ID. I'm trying to compile the code since so long, but I keep getting errors in the .icf file, and I don't know how to resolve them. Basically, all the identifiers/ keywords in the .icf file show the same error "undefined definition". Can anyone help with understanding, what mistake I'm making or step I'm following which is not the right way?
