c++ makfile error: makefile:5: *** missing separator. Stop

Question

I'm trying to run my c++ (written in clion) program in linux. When I try to compile it in the terminal using "make" command, I get this error: "makefile:5: *** missing separator. Stop." I already checked that there tabs and not 4 spaces in my makefile. Anyone has an idea? Thanks!

This is my makefile:

CFLAGS := -c -Wall -Weffc++ -g -std=c++11 -Iinclude
LDFLAGS := -lboost_system

all: StompBookClubClient
    g++ -pthread -o bin/StompBookClubClient bin/ConnectionHandler.o  bin/Book.o bin/keyboardInputSend.o bin/socketReader.o bin/User.o $(LDFLAGS)

StompBookClubClient: bin/StompBookClubClient bin/ConnectionHandler.o  bin/Book.o bin/keyboardInputSend.o bin/socketReader.o bin/User.o

bin/Book.o: src/Stomp/Book.cpp
    g++ -pthread $(CFLAGS) -o bin/Book.o src/Book.cpp

bin/ConnectionHandler.o: src/Stomp/ConnectionHandler.cpp
    g++ -pthread $(CFLAGS) -o bin/ConnectionHandler.o src/ConnectionHandler.cpp

bin/keyboardInputSend.o: src/Stomp/keyboardInputSend.cpp
    g++ -pthread $(CFLAGS) -o bin/keyboardInputSend.o src/keyboardInputSend.cpp

bin/socketReader.o: src/Stomp/socketReader.cpp
    g++ -pthread $(CFLAGS) -o bin/socketReader.o src/socketReader.cpp

bin/StompBookClubClient.o: src/Stomp/StompBookClubClient.cpp
    g++ -pthread $(CFLAGS) -o bin/StompBookClubClient.o src/StompBookClubClient.cpp

bin/User.o: src/Stomp/User.cpp
    g++ -pthread $(CFLAGS) -o bin/User.o src/User.cpp

.PHONY: clean
clean:
    rm -f bin/*

Answer 1

I already checked that there tabs and not 4 spaces in my makefile.

Check it a bit harder. The Makefile you pasted here has 4 spaces on line 5 and produces exactly the error you are seeing. If I replace them by a tab, the next error occurs on line 10, and so on.

Answer 2

This is not an answer but I do not have sufficient points to comment and hence answering.

Apart from 'tab' issue ,you get a similar error if ':'(colon) is missed after the rule name.

Ex makefile:

helloworld.o
    g++ helloworld.cc -o helloworld.o;

Error:

Makefile:1: *** missing separator.  Stop.

Solution: Colon after helloworld.o like below

helloworld.o:
    g++ helloworld.cc -o helloworld.o;
