libevhtp windows build

windows 编译evhtp 说明

依赖库

evhtp依赖库

• openssl（主要为了https）
• libevent
• pthread （多线程模式）

编译工具

• vs 2017
• perl

# 判断系统是否安装cmake
where cmake
D:\vs2008\Common7\IDE\CommonExtensions\Microsoft\CMake\CMake\bin\cmake.exe

# 判断系统是否安装 perl
where perl
D:\Strawberry\perl\bin\perl.exe

编译opensll

工具

• x86 Native Tools Command Prompt for VS 2017(vs2017 命令行 编译32位库)

下载源码

# 这里什么方式下载都行
# 下载完解压
curl -O 'https://www.openssl.org/source/old/1.0.1/openssl-1.0.1u.tar.gz'
tar -xzvf openssl-1.0.1u.tar.gz
cd openssl-1.0.1u

编译

# 在vs 命令行中进行操作
$ perl Configure VC-WIN32 --prefix="D:\vs2008\code\openssl\openssl" --openssldir="D:\vs2008\code\openssl\ssl"
$ ms\do_ms
$ nmake -f ms\nt.mak 
$ nmake -f ms\nt.mak test
# 安装库和openssl工具
$ nmake -f ms\nt.mak install

编译libevent

下载源码

# 下载源码
libevent-2.0.22-stable.tar.gz
# 解压源码
tar -xzvf libevent-2.0.22-stable.tar.gz

修改配置文件

• 需要修改Makefile.nmake 修改内容当作参考
• 主要为了生成 libevent_openssl.lib， libevent_pthreads.lib 库

# 查看文件
$ cat Makefile.nmake


# WATCH OUT!  This makefile is a work in progress.  It is probably missing
# tons of important things.  DO NOT RELY ON IT TO BUILD A GOOD LIBEVENT.

# 目前使用的分支
git checkout 1.2.13

修改部分源码

• 为了编译源码，源码有一些改动。

编译工具

• x86 Native Tools Command Prompt for VS 2017(vs2017 命令行 编译32位库)
• cmake
• vs 2017

编译

# 第一步
# 进入 vs 命令行（x86 编译32位库）
# 使用cmake 生成vs 工程
# 这个地方 主要是 开启几个宏定义，代码中开启相应功能
# 只是一个参照，需要根据不同版本 进行调整

vs 编译

# 第二步
# cmake 之后 vs就可以打开工程

# 在vs 中添加
# pthread include
# opensll include

# 点击生成，可以生成对应的库

# 复制生成的头文件(所有)

build/include
build/compat
include

# lib库位置

build/Debug/

编译中遇到的问题

# cmake 修改
cmake 查看系统中是否有openssl库，查找不到cmake不过。需要注释一些配置，使其可以通过

# 会报strndup 奇怪错误
需要把定义放在调用前面

# 开启pthread时，各种奇怪错误
需要包含<sys/queue.h> 头文件

# 具体细节看，evhtp中的改动

例子

#include <stdio.h>

#include <WinSock2.h>      // windows socket

#include <iostream>
#include <string.h>
#include "evhtp.h"
