一.編譯.so

CC = gcc
CFLAGS =

# opencv 標頭檔案和lib路徑
OPENCV_INC_ROOT = ../include
OPENCV_LIB_ROOT = /usr/local/lib

#.o檔案與.cpp檔案同名
OBJS = aaa..o
# 目標檔名
LIB = ../lib/libcommon.so

OPENCV_INC = -I $(OPENCV_INC_ROOT)

INCLUDE_PATH = $(OPENCV_INC)

LIB_PATH = -L $(OPENCV_LIB_ROOT)

# 依賴的lib名稱
OPENCV_LIB = -lopencv_objdetect -lopencv_core -lopencv_highgui -lopencv_imgproc

all : $(LIB)

# 2. 生成.o檔案
%.o : %.c
    #$(CC) $(CFLAGS) -fpic -c $< -o

[email protected] $(INCLUDE_PATH) $(LIB_PATH) $(OPENCV_LIB)
    $(CC) $(CFLAGS) $(INCLUDE_PATH) -fpic -c $< -o [email protected]
# 3. 生成動態庫檔案
$(LIB) : $(OBJS)
    rm -f [email protected]
    g++ -shared -o [email protected] $(OBJS)
    rm -f $(OBJS)

tags :
    ctags -R *

# 4. 刪除中間過程生成的檔案
clean:
    rm -f $(OBJS) $(TARGET) $(LIB)

二.編譯普通程式

CFLAGS = -g3
target = info-collect_new
INCLUDE = -I /usr/local/xxx/common/include
lib = -lcommon -lpthread
dirlib = -L /usr/lib/x86_64-linux-gnu/ -L /usr/local/xxx/common/lib/
object = $(patsubst %.cpp,%.o,$(wildcard *.cpp))
$(target):$(object)
     g++ $(CFLAGS) $(INCLUDE) $(object)  -o $(target) $(dirlib) $(lib) -Wl,-rpath=/usr/local/xxx/common/lib/
$(object):%.o:%.cpp
     g++ $(CFLAGS) $(INCLUDE) -c $< -o

[email protected]
.PHONY : clean
clean:
     rm $(object) $(target)
