Cpp web(一) Ubuntu下安装使用Crow服务

Ubuntu下安装Crow

#1 环境

C++11
boost 1.58.0
Ubuntu 16.04
cmake 3.18.2 
Clion

#2 安装

#2.1 安装Boost

C++ Crow 依赖boost

1. 下载boost源码

https://www.boost.org/users/history/version_1_58_0.html

2. 进入解压后的文件

cd boost_1_58_0

3. 执行

./booststrap.sh
// 必须要sudo 
sudo ./b2 install 

一两分钟分钟之后编译安装完成

• 头文件 : /usr/local/include/boost
• 库文件 : /usr/local/lib

#2.2 安装Crow

1. 下载Crow源码

我这里将Crow安装在/home/trunk/路径下

cd /home/trunk/
git clone  https://github.com/ipkn/crow.git
cd  crow 
mkdir build
cd build
cmake ..
make
ctest 

2. 测试Crow安装是否成功

在刚刚新建的build目录下,有一个二进制文件 build/examples/example, 运行一个最简单的http请求,端口号:18080

./example

#3 使用

#3.1 Clion

1. 使用Clion创建一个最简单的工程

我这里的工程名为: crow_demo

2. 配置CMakeLists.txt

cmake_minimum_required(VERSION 3.17)
project(crow_demo)

set(CMAKE_CXX_STANDARD 11)

set(BOOST_ROOT "/usr/local/include/boost")
set(BOOSTROOT "/usr/local/include/boost")
include_directories(/usr/local/include)
link_directories(/usr/local/lib)

FIND_PACKAGE(Threads REQUIRED)
SET(Boost_USE_MULTITHREADED ON)

find_package(Boost REQUIRED COMPONENTS system)

add_executable(crow_demo main.cpp)

target_link_libraries(crow_demo boost_thread boost_system ${CMAKE_THREAD_LIBS_INIT})

include_directories(/home/trunk/crow/include/)

3. main.cpp

#include <iostream>
#include "crow.h"

int main()
{
    crow::SimpleApp app;

    CROW_ROUTE(app, "/")([](){
        return "Hello C++ Crow";
    });

    app.port(9876).multithreaded().run();
}
