I'm trying to write a simple make file that automatically finds all C++
source files, compiles a corresponding object file and puts it in
directory "build" and then links the resulting binary. But I don't know
how to put the object files in directory "build" - they always end up
in the same directory as the source files.
Here is my make file:
# ============
# Variables
# ============
PROGRAM = program.bin
CXX = c++
SOURCES = $(shell ls src/*.cpp)
OBJECTS = $(SOURCES:.cpp=.o)
INCS = -Iinclude -Igfx
LIBS = -L/app/glib/1.2.10/lib -L/app/gtk+/1.2.10/lib
# ============
# Targets
# ============
$(PROGRAM): $(OBJECTS)
$(CXX) -o $(PROGRAM) $(OBJECTS) $(LIBS)
%.o : %.cpp
$(CXX) -c $(INCS) -o $@ $<
clean:
\rm src/*.o $(PROGRAM)
I suppose I have to move the object file at the end of target "%.o" to
the "build" directory, but I don't know how.
