Answer 1

You can also use wild cards to specify all files in the directory.

eg:

#Generic Makefile.

CC := g++

LD := g++

CFLAGS := -c

LDFLAGS := -L -l \

           -L -l>libname> \
            ......................

ifeq (${TARGETARCH}, debug)

  CFLAGS += -g -O0

elif 

  CFLAGS += -O4 -DNDEBUG

SRCFILES := $(wildcard *.cpp)

OBJFILES := $(patsubst %.cpp, %.o, ${SRCFILES})


all: main

main: ${OBJFILES}

  @echo "[Linking]"$@

  ${LD} ${LDFLAGS} ${OBJFILES}

%.o: %.cpp

  @echo "[Compiling]"$@

  ${CC} ${CFLAGS} $^ -o $@
