I recently started learning C language on Ubuntu 15.10 .Today I learned about Makefile from http://c.learncodethehardway.org/book/ex2.html .But the problem is I keep on getting error
bharat@ratcoder:~/Programing/C$ make Makefile:4: *** missing separator (did you mean TAB instead of 8 spaces?). Stop.
I know I have to use Tab key instead of spaces and I am using the Tab key,But when using Tab does not solve my problem I tried googling and use
this in vim as advised here https://unix.stackexchange.com/questions/125757/error-while-executing-make-commad-in-ubuntu-terminal. But still I get the same error as above,so someone please help me where I am wrong or what should I do.I am new to Ubuntu.
