"make: *** no rule to make target 'all' Eclipse Error

Question

I have read many threads about this problem, but I was not able to solve it.

I'm running on Linux, with Eclipse and CDT plugin installed. I have an existing C project, located in /home/luca/prova. In this folder there are some source files and a makefile (called makefile), that I report below:

CC = gcc
CFLAGS = -Wall -Werror -O2
HEADERS = lz78_compressor.h lz78_decompressor.h 
SOURCES := $(wildcard *.c)
OBJ = $(SOURCES:.c=.o)
EXECUTABLE = lz78


.PHONY : clean install uninstall help


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


$(EXECUTABLE) : $(OBJ)
    $(CC) -o $@ $^ $(CFLAGS)
    @echo "Build finished. Executable file created : $(EXECUTABLE)"

clean : 
    rm -f $(EXECUTABLE) $(OBJ)


install :
    -@cp ./$(EXECUTABLE) /usr/bin
    @echo "Tool installed"


uninstall :
    -@rm /usr/bin/$(EXECUTABLE)
    @echo "Tool uninstalled"


help :
    @echo
    @echo "Makefile"
    @echo
    @echo "make                     : build all"
    @echo "install          : install the tool in the system"
    @echo "uninstall        : remove the tool from the system"
    @echo "clean            : remove all .o files and the executable file"
    @echo 

If I compile in the shell, it works all fine. But I want to import it in Eclipse. Following this wiki, http://help.eclipse.org/neon/index.jsp?topic=%2Forg.eclipse.cdt.doc.user%2Fgetting_started%2Fcdt_w_import.htm I create a new C project, then I modify settings about the project building. In the next image there are the settings that I set:

When I try to build the project, I see the error

"make: *** no rule to make target 'all'

Why? Anyone could help me?

Thanks

Answer 1

You don't have an all target in your Makefile.

Option 1

Try adding this as a line to tell make what to do when make all is done:

all: $(EXECUTABLE)

Option 2

You can add extra Make rules with the Make Target View in Eclipse CDT.
