Wimax package with ns_2

This is a common error received during compiling (making) ns2 after some modification.

It means you are doing some copy-past operation in makefile. The copy-past operation will add some non standard end of line characters at end of those lines. The make command will fail if it will ‘see’ those strange end of line characters. So, you can remove those unwanted characters using a suitable text editor(lean it).

Or simply type those new lines in makefile using a simple editor like “vi”(lean it).

It will solve the problem.
