Ubuntu – 编译安装libhv
1 编译安装libhv
编译libhv需要：
- gcc4.8+
- cmake 3.6 or later
官方编译文档可参考：https://github.com/ithewei/libhv/blob/master/BUILD.md
官方提供了两种编译方式，一种是Makefile，另一种是CMake，本文以CMake为例进行说明。
2 CMake编译libhv
首先下载libhv，这里以libhv v1.3.2为例
wget -c https://github.com/ithewei/libhv/archive/refs/tags/v1.3.2.tar.gz
解压缩
tar -xvf v1.3.2.tar.gz
进入到解压缩目录
cd libhv-1.3.2
创建build文件夹，进入build文件夹
mkdir build
cd build
然后通过cmake进行编译
cmake ..
cmake --build .
或者
cmake ..
make
cmake提供了比较多的编译选项，具体可参考官方CMakeLists，主要的编译选项如下
option(BUILD_SHARED "build shared library" ON)
option(BUILD_STATIC "build static library" ON)
option(BUILD_EXAMPLES "build examples" ON)
option(BUILD_UNITTEST "build unittest" OFF)
# see config.ini
option(WITH_PROTOCOL "compile protocol" OFF)
option(WITH_EVPP "compile evpp" ON)
option(WITH_HTTP "compile http" ON)
option(WITH_HTTP_SERVER "compile http/server" ON)
option(WITH_HTTP_CLIENT "compile http/client" ON)
option(WITH_MQTT "compile mqtt" OFF)
option(ENABLE_UDS "Unix Domain Socket" OFF)
option(USE_MULTIMAP "MultiMap" OFF)
option(WITH_CURL "with curl library (deprecated)" OFF)
option(WITH_NGHTTP2 "with nghttp2 library" OFF)
option(WITH_OPENSSL "with openssl library" OFF)
option(WITH_GNUTLS "with gnutls library" OFF)
option(WITH_MBEDTLS "with mbedtls library" OFF)
option(WITH_KCP "compile event/kcp" OFF)
在通过cmake ..默认编译的情况下会同时编译动态库和静态库，编译完成之后：
- include目录位于build/include目录下
- 动态库和静态库位于build/lib目录下
然后使用
make install
进行安装，安装之后的路径为
- include目录：/usr/local/include
- 静态库目录：/usr/local/lib
- 动态库目录：/usr/local/lib
安装完成之后，使用以下命令
sudo ldconfig
使得动态链接库配置生效，就可以在自己的项目中动态链接libhv库了。
详细的安装日志为

3 自定义demo cmake编译示例
新建一个main.cpp，在其中加入以下代码
#include <iostream>
#include "hv/HttpServer.h"
int main() {
HttpService router;
router.GET("/ping", [](HttpRequest* req, HttpResponse* resp) {
return resp->String("pong");
});
router.GET("/data", [](HttpRequest* req, HttpResponse* resp) {
static char data[] = "0123456789";
return resp->Data(data, 10);
});
router.GET("/paths", [&router](HttpRequest* req, HttpResponse* resp) {
return resp->Json(router.Paths());
});
router.GET("/get", [](HttpRequest* req, HttpResponse* resp) {
resp->json["origin"] = req->client_addr.ip;
resp->json["url"] = req->url;
resp->json["args"] = req->query_params;
resp->json["headers"] = req->headers;
return 200;
});
router.POST("/echo", [](const HttpContextPtr& ctx) {
return ctx->send(ctx->body(), ctx->type());
});
http_server_t server;
server.port = 8080;
server.service = &router;
std::cout << "run success" << std::endl;
http_server_run(&server);
return 0;
}
然后在同级目录下创建一个CMakeLists.txt。
如果是静态链接libhv，则CMakeLists.txt的内容为
cmake_minimum_required(VERSION 3.6)
project(myhvtest)
set(CMAKE_BUILD_TYPE Release)
set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} -fPIC")
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++14 -O3 -pthread -fPIC -ldl")
# 添加宏定义
add_definitions(-DHV_STATICLIB)
# 链接静态库
link_libraries(libhv_static.a)
add_executable(${PROJECT_NAME} main.cpp)
如果是动态链接libhv，则CMakeLists.txt的内容为
cmake_minimum_required(VERSION 3.6)
project(myhvtest)
set(CMAKE_BUILD_TYPE Release)
set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} -fPIC")
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++14 -O3 -pthread -fPIC -ldl")
add_executable(${PROJECT_NAME} main.cpp)
target_link_libraries(${PROJECT_NAME} hv)
然后依次执行以下命令进行编译
mkdir build
cd build
cmake ..
make
编译成功之后会在build目录下生成一个myhvtest的可执行文件。
如何判断可执行程序是否动态链接libhv成功？
使用以下命令
ldd ./myhvtest
如果出现以下日志则说明链接成功
[root@ai-0008 build]# ldd ./myhvtest
linux-vdso.so.1 => (0x00007ffe9f138000)
