3.C++ boost库和muduo库的编译安装

muduo库是基于boost开发的，需要先在Linux平台上安装boost库

boost的源码下载地址:https://boostorg.jfrog.io/artifactory/main/release/

下载.tar.gz
tar -xvf boost*
./bootstrap.sh
./b2
./b2 install

打开vs2019的命令行窗口,切换到下载好的boost源码的位置

./bootstrap.bat
./b2
./b2 install

如图,我电脑的源码安装位置是c盘

在vs中的配置

#include 
#include 
#include 
using namespace std;

class A
{
public:
	void func(string name)
	{
		cout << name << " A: hello world!" << endl;
	}
};

int main()
{
	A a;
	auto func = boost::bind(&A::func, &a, "boost");
	func();
	return 0;
}

muduo是基于boost开发的,需要先安装boost库,用git clone来在linux上下载源码

git clone https://github.com/chenshuo/muduo.git

muduo库源码编译会编译很多unit_test测试用例代码，编译耗时长，也用不到,在源码目录打开 CMakeLists.txt.

vim CMakeLists.txt

./build.sh
./build.sh install

./build.sh install把muduo的头文件和lib库文件放到了muduo-master同级目录下的build目录下的release-install-cpp11文件夹下

cd release-install-cpp11/ 

配置以下信息,就可以不用在指定头文件和lib库文件路径,g++会自动从/usr/include和/usr/local/lib路径下寻找所需要的文件。

cd include/
mv muduo/ /usr/include/
cd ../lib/
mv * /usr/local/lib/

  // 接收到所有的消息，然后回显
  muduo::string msg(buf->retrieveAllAsString());

  loop.loop();
