下载

从GitHub下载最新版本的 curl 源码：

git clone https://github.com/curl/curl.git

安装cmake

一句话的事情：

sudo apt-get install cmake

编译curl

进入curl目录下，创建一个build文件夹，用于存放编译产生的中间文件、动态库、头文件等内容：

cd curlmkdir build

进入build文件夹

cd build

通过cmke生成Makefile，注意，cmake的语法是：cmake [路径]，.. 表示上一级目录

cmake ..

在执行完成后你会发现当前目录下存在一个Makefile文件，你直接make就可以编译了。

make

安装

在编译完成后，可以进行安装，注意要用sudo权限：

sudo make install

它按照的位置信息如下：

-- Install configuration: ""
-- Installing: /usr/local/bin/curl-config
-- Installing: /usr/local/lib/pkgconfig/libcurl.pc
-- Installing: /usr/local/include/curl
-- Installing: /usr/local/include/curl/urlapi.h
-- Installing: /usr/local/include/curl/stdcheaders.h
-- Installing: /usr/local/include/curl/curl.h
-- Installing: /usr/local/include/curl/typecheck-gcc.h
-- Installing: /usr/local/include/curl/system.h
-- Installing: /usr/local/include/curl/multi.h
-- Installing: /usr/local/include/curl/easy.h
-- Installing: /usr/local/include/curl/curlver.h
-- Installing: /usr/local/include/curl/mprintf.h
-- Installing: /usr/local/lib/cmake/CURL/CURLTargets.cmake
-- Installing: /usr/local/lib/cmake/CURL/CURLTargets-noconfig.cmake
-- Installing: /usr/local/lib/cmake/CURL/CURLConfigVersion.cmake
-- Installing: /usr/local/lib/cmake/CURL/CURLConfig.cmake
-- Installing: /usr/local/lib/libcurl.so
-- Installing: /usr/local/bin/curl
-- Set runtime path of "/usr/local/bin/curl" to ""

最后更新一下系统的链接库信息，注意也要用sudo权限：

sudo ldconfig -v

简单使用

在curl的example随便找一个例子：

https.c

/****************************************************************************                                  _   _ ____  _*  Project                     ___| | | |  _ \| |*                             / __| | | | |_) | |*                            | (__| |_| |  _ <| |___*                             \___|\___/|_| \_\_____|** Copyright (C) 1998 - 2019, Daniel Stenberg, <daniel@haxx.se>, et al.** This software is licensed as described in the file COPYING, which* you should have received as part of this distribution.

#include <stdio.h>
#include <curl/curl.h>int main(void)
{CURL *curl;CURLcode res;curl_global_init(CURL_GLOBAL_DEFAULT);curl = curl_easy_init();if(curl) {curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/");#ifdef SKIP_PEER_VERIFICATION/** If you want to connect to a site who isn't using a certificate that is* signed by one of the certs in the CA bundle you have, you can skip the* verification of the server's certificate.

#endif#ifdef SKIP_HOSTNAME_VERIFICATION/** If the site you're connecting to uses a different host name that what* they have mentioned in their server certificate's commonName (or* subjectAltName) fields, libcurl will refuse to connect.

#endif/* Perform the request, res will get the return code */res = curl_easy_perform(curl);/* Check for errors */if(res != CURLE_OK)fprintf(stderr, "curl_easy_perform() failed: %s\n",curl_easy_strerror(res));/* always cleanup */curl_easy_cleanup(curl);}curl_global_cleanup();return 0;
}

然后随便编写一个Makefile文件，注意需要动态链接curl库 -lcurl：

Makefile：

CC=gcc
SRC = $(wildcard *.c */*.c)
OBJS = $(patsubst %.c, %.o, $(SRC))
DEP_FILES := $(patsubst %, .%.d,$(OBJS))
DEP_FILES := $(wildcard $(DEP_FILES))
FLAG = -g -Werror -I. -Iinclude -lpthread -lcurl
TARGET = targets$(TARGET):$(OBJS)$(CC) -o $@ $^ $(FLAG)ifneq ($(DEP_FILES),)
include $(DEP_FILES)
endif%.o:%.c$(CC) -o $@ -c $(FLAG) $< -g -MD -MF .$@.dclean:rm -rf $(TARGET) $(OBJS)distclean:rm -rf $(DEP_FILES).PHONY:clean

编译并运行：

013 git:(master) ✗ makegcc -o https.o -c -g -Werror -I. -Iinclude -lpthread -luv -lcurl https.c -g -MD -MF .https.o.d
gcc -o targets https.o -g -Werror -I. -Iinclude -lpthread -luv -lcurl➜  013 git:(master) ✗ ./targets <!doctype html>
