This is the first time i'm trying to create a make file. and it looks like there is an error. Could you help me with it? The line that is in bold has the error according to the output.

Answer 1

Make is very picky about spaces vs. tabs. Command lines absolutely must be indented with a single tab, and not spaces. You may need to adjust your editor to generate tab characters.
