This is my makefile:
all:ll ll:ll.c gcc -c -Wall -Werror -02 c.c ll.c -o ll $@ $< clean : \rm -fr ll When I try to make clean or make make, I get this error:
:makefile:4: *** missing separator. Stop. How can I fix it?

Recipes in makefile rules must start with a tab (per definition). If a single tab (interpreted as 8 spaces wide) is not enough to put the recipe clearly indented (meaning at least 4 spaces difference) from the code around it, use additional tabs.
What Makefiles Contain. Makefiles contain five kinds of things: explicit rules , implicit rules , variable definitions , directives , and comments . Rules, variables, and directives are described at length in later chapters. An explicit rule says when and how to remake one or more files, called the rule's targets.
make has a very stupid relationship with tabs. All actions of every rule are identified by tabs. And, no, four spaces don't make a tab. Only a tab makes a tab.
To check, I use the command cat -e -t -v makefile_name.
It shows the presence of tabs with ^I and line endings with $. Both are vital to ensure that dependencies end properly and tabs mark the action for the rules so that they are easily identifiable to the make utility.
Example:
Kaizen ~/so_test $ cat -e -t -v mk.t all:ll$ ## here the $ is end of line ... $ ll:ll.c $ ^Igcc -c -Wall -Werror -02 c.c ll.c -o ll $@ $<$ ## the ^I above means a tab was there before the action part, so this line is ok . $ clean :$ \rm -fr ll$ ## see here there is no ^I which means , tab is not present .... ## in this case you need to open the file again and edit/ensure a tab ## starts the action part If you love us?
