Hope this helps Replace all that is not a file and does not exist (reason why make tries to build it each time) by program, a real file that make can see. If you really want an all symbolic target, declare it as phony and add a rule without recipe to tell make that all depends on program:
code :
.PHONY: all
all: program

this will help I found the answer, sort of:
The problem was with the installation process of LLVM. It seems that if you do the installation in one order instead of another it can lead to this error. It doesn't make any sense to me, but after I installed it properly everything compiles great (same code, same Makefile, same make program).

I wish did fix the issue. Put exprtest on the same line as all. Dependencies come after the colon, commands come on the following lines, indented.
code :
target: dependencies
[tab] system command
all: exprtest
exprtest: exptrtest.o driver.o parser.tab.o scanner.o
    g++ -Wall -g -o exprtest exptrtest.o driver.o parser.tab.o scanner.o

I wish this helpful for you My C++ program consists of three files: , You need to change:
code :
OBJECTS = ./bin/main.o \
          ./bin/hellolib.o
OBJECTS = bin/main.o \
          bin/hellolib.o
./bin/%.o : src/%.cpp
        $(CC) -c $< -o $@
SOURCES = src/main.cpp \
          src/hellolib.cpp

OBJECTS = $(patsubst src/%.cpp,bin/%.o,$(SOURCES))

may help you . Just a guess but maybe the 'clean' target in the second makefile calls 'clean-linux'?
Can you post the clean target of the second makefile?
