A simple example of the recording makefile

Build its shared library

######################################
# makefile shared library 
######################################
# set your all envrionment.
CC=g++
CC_FLAGS=-D_FILELINE
SRCS=$(wildcard *.cpp */*.cpp)

# set your all inc and lib
INCS=-I.
LIBS=-lpthread -L.  

#make taget lib and relevent obj
TARGET=libxxdk.so
OBJS=$(patsubst %.cpp, %.o, $(SRCS))

#all target 
all:$(TARGET)
$(TARGET):$(OBJS)
	$(CC) -shared -o $@ $^ $(LIBS)

%.o:%.cpp
	$(CC) $(CC_FLAGS) $(INCS) -c -fpic $< -o $@ -g

clean:
	rm -rf $(TARGET) $(OBJS)

Compile static library

######################################
# makefile static library 
######################################
# set your all envrionment.
CC=g++
AR=ar
CC_FLAGS=-D_FILELINE
SRCS=$(wildcard *.cpp */*.cpp)

# set your all inc and lib
INCS=-I.
LIBS=-lpthread -L.  

#make taget lib and relevent obj
TARGET=libxxdk.a
OBJS=$(patsubst %.cpp, %.o, $(SRCS))

#all target 
all:$(TARGET)
$(TARGET):$(OBJS)
	$(AR) crv $@ $^

%.o:%.cpp
	$(CC) $(CC_FLAGS) $(INCS) $(LIBS) -c $< -o $@  -g

.PHONY: clean
clean:
	rm -rf $(TARGET) $(OBJS)

Compiled executable file

######################################
# makefile executable 
######################################
# set your all envrionment.
CC=g++
CC_FLAGS=-D_FILELINE
SRCS=$(wildcard *.cpp */*.cpp)

# set your all inc and lib
INCS=-I.
LIBS=-lpthread -L.  

#make taget lib and relevent obj
TARGET=xxdk
OBJS=$(patsubst %.cpp, %.o, $(SRCS))

#all target 
all:$(TARGET)
$(TARGET):$(OBJS)
	$(CC) -o $@ $^

%.o:%.cpp
	$(CC) $(CC_FLAGS) $(INCS) $(LIBS) -c $< -o $@  -g

.PHONY: clean
clean:
	rm -rf $(TARGET) $(OBJS)
