create makefile for static library and executable simultaniously

I have 3 files which should included in static library (file1.c,file2.c,file3.c) and one file which should include the main function (main.c file) and linked to the static library.

I would like to create one makefile that create the library and then create the executable.

My base makefile is:

CC=gcc
CFLAGS=-c -Wall
LDFLAGS=
SOURCES=file1.c file2.c file3.c
OBJECTS=$(SOURCES:.c=.o)
OUT=libctest.a
EXECUTABLE=hello
LDFLAGS = -static

.c.o:
    $(CC) $(CFLAGS) -c $< -o $@

$(OUT): $(OBJECTS)
    ar rcs $(OUT) $(OBJECTS)

all:
    (CC) -o $(EXECUTABLE) main.c $(OUT)

clean:
    rm -f $(OBJECTS) $(OUT)

The library is created but the executable doesn't created (all: (CC) -o $(EXECUTABLE) main.c $(OUT)) Any idea what is needed?

Make will by default process the first target in the Makefile. In your case this is the .c.o target. To make all the default target move it to the top. Many people would prefer a style where all won't do anything but rather depend on others. Something along those lines:

all: $(EXECUTABLE)

$(OUT): $(OBJECTS)
    ar rcs $(OUT) $(OBJECTS)

$(EXECUTABLE): main.c $(OUT)
    (CC) -o $(EXECUTABLE) main.c $(OUT)
