makefile如何调用静态库的方法实现
makefile如何调用静态库
1、在windows下g++环境中，调用一个python的静态链接库，在makefile文件有一段是全局的g++命令：
$(PROG):$(OBJS) $(CXX)$(LFLAGS)$^-o$@
现在我要链接上一个python的静态库，lib存储在makefile同目录下libs文件夹下：
$(PROG):$(OBJS) $(CXX)$(LFLAGS)$^-o$@./libs/libpython37.a
2、在LinuxUbuntu18.04版本中添加静态库，视python版本而定：
$(PROG):$(OBJS) $(CXX)$(LFLAGS)$^-o$@-lpython3.6m
Makefile如何调用opencv的静态库
main.cpp
#include#include"opencv2/opencv.hpp" intmain() { cv::Matimage=cv::imread("./testPic/jianhui.jpg"); //cv::imshow("xxx",image); //cv::waitKey(40); printf("image.col=%dimage.row=%d\n",image.cols,image.rows); cv::imwrite("aa.jpg",image); return0; }
Makefile
EXE=main
#SUBDIR=srcobject
#CXXFLAGS:编译选项,LDFLAGS:链接选项
thirdparty_root:=/local_install/static
CC:=g++
#exportPKG_CONFIG_PATH:=${thirdparty_root}/lib/pkgconfig:${PKG_CONFIG_PATH}
#INCS+=`pkg-config--cflagsopencv`
#LIBS+=`pkg-config--libsopencv`

LDFLAGS:=$(LIBS)
LDFLAGS+=-lpthread
#LDFLAGS+=-Wl,-rpath,${thirdparty_root}/share/OpenCV/3rdparty/lib:${thirdparty_root}/lib:#动态库的时候需要寻找的路径
#CXX_SOURCES=$(foreachdir,$(SUBDIR),$(wildcard$(dir)/*.cpp))
#CXX_OBJECTS=$(patsubst%.cpp,%.o,$(CXX_SOURCES))
CXX_OBJECTS:=$(patsubst%.cpp,%.o,$(shellfind.-name"*.cpp"))
DEP_FILES=$(patsubst%.o,%.d,$(CXX_OBJECTS))
$(EXE):$(CXX_OBJECTS)
$(CC)$(CXX_OBJECTS)-o$(EXE)$(LDFLAGS)
%.o:%.cpp
$(CC)-c$(CXXFLAGS)-MMD$<-o$@
-include$(DEP_FILES)
clean:
rm-rf$(CXX_OBJECTS)$(DEP_FILES)$(EXE)
test:
echo$(CXX_OBJECTS)
上面的Makefile是用调用动态库的方式来调用静态库，如果同时存在静态库和动态库，会优先调用动态库
EXE=CppWebServer
#SUBDIR=srcobject
#CXXFLAGS:编译选项,LDFLAGS:链接选项
CC:=g++
thirdparty_root:=/local_install/static
#INCS+=`pkg-config--cflagsopencv`

INCS+=-I/usr/lib/jdk1.8.0_191/include/linux/
INCS+=-I./include
INCS:=-I${thirdparty_root}/include
#这种方式调用静态库，保证在在动态库也存在的时候也能调用到静态库
