Linux下静态链接库和动态链接库的创建与使用

1 创建链接库

使用简单的一个函数来实现链接库功能，函数实现如下：
library.cpp文件：

#include "library.h"

#include 

void hello() {
    std::cout << "Hello, library World!" << std::endl;
}

library.h文件：

#ifndef LIB_PUBLISHER_LIBRARY_H
#define LIB_PUBLISHER_LIBRARY_H

void hello();

#endif //LIB_PUBLISHER_LIBRARY_H

链接库生成的CMakeLists文件：

cmake_minimum_required(VERSION 2.8)
project(lib_publisher)

set(CMAKE_CXX_STANDARD 11)
SET (LIB_PUBLISHER_SRC library.cpp library.h)

add_library(lib_publisher SHARED ${LIB_PUBLISHER_SRC})
ADD_LIBRARY (lib_publisher_static STATIC ${LIB_PUBLISHER_SRC})

INSTALL (TARGETS lib_publisher lib_publisher_static LIBRARY DESTINATION lib

        ARCHIVE DESTINATION lib)

INSTALL (FILES library.h DESTINATION include/library)

将链接库生成动态和静态两种链接库，并安装到系统的指定位置（/usr/local/bin与/usr/local/include）。

2 在项目中使用动态链接库

CMakeLists文件：

cmake_minimum_required(VERSION 2.8)
project(ExoSSimulator)
add_definitions(-std=c++11)

set(CMAKE_CXX_STANDARD 11)


find_library(
        pub
        lib_publisher
)


add_executable(simulator main.cpp src/communication/Server.cpp src/utilities/unchararray_utility.cpp include/Server.h include/wraper.h include/unchararray_utility.h)
target_link_libraries(simulator ${pub})

其中lib_publisher为在1中动态链接库中生成的名称。
在工程中直接引入.h文件#include "library/library.h",
并调用hello()。
结果如下：
