编译和交叉编译curl

## 一、Linux下编译curl： ##

在编译或交叉编译curl之前需要对应编译或交叉编译openssl，详细见：  
https://blog.csdn.net/qq\_43603677/article/details/105064209  
先下载curl安装包curl-7.69.1.tar.gz并解压安装包：  
tar vxf curl-7.69.1.tar.gz：

root@kwt-virtual-machine:/home/kwt# tar vxf curl-7.69.1.tar.gz

进入curl-7.69.1目录：

执行./configure命令生成Makefile：

root@kwt-virtual-machine:/home/kwt/curl-7.69.1# ./configure --prefix=/home/kwt/curl

然后执行make和make install:

root@kwt-virtual-machine:/home/kwt/curl-7.69.1# make

root@kwt-virtual-machine:/home/kwt/curl-7.69.1# make install

完成后在/home/kwt/下生成curl文件夹，curl安装成功。  
下面写一个简单使用libcurl的例子：  
curl\_test.c：

#include <stdio.h>
    #include "/home/kwt/curl/include/curl/curl.h"
     
    int main(void)
    { 
      CURL *curl;
      CURLcode res;
     
      /* http://curl.haxx.se/libcurl/c/curl_easy_init.html */
      curl = curl_easy_init();
      if(curl) { 
        /* http://curl.haxx.se/libcurl/c/curl_easy_setopt.html#CURLOPTURL */
        curl_easy_setopt(curl, CURLOPT_URL, "http://127.0.0.1/index.html");
        /* http://curl.haxx.se/libcurl/c/curl_easy_perform.html */
        res = curl_easy_perform(curl);
     
        if(CURLE_OK == res) { 
          char *ct;
          /* ask for the content-type */
          /* http://curl.haxx.se/libcurl/c/curl_easy_getinfo.html */
          res = curl_easy_getinfo(curl, CURLINFO_CONTENT_TYPE, &ct);
     
          if((CURLE_OK == res) && ct)
            printf("We received Content-Type: %s\n", ct);
        }
     
        /* always cleanup */
        /* http://curl.haxx.se/libcurl/c/curl_easy_cleanup.html */
        curl_easy_cleanup(curl);
      }
      return 0;
    }

执行gcc curl\_test.c -o curl\_test -L/home/kwt/curl/lib/ -lcurl得到可执行文件，执行可执行文件如下：

root@kwt-virtual-machine:/home/kwt/Test/3# ./curl_test

## 二、交叉编译curl： ##

同样下载安装curl-7.69.1.tar.gz并解压安装包，进入curl-7.69.1目录之后执行一下命令生成Makefile：

CPPFLAGS="-I/home/kwt/openssl/aarch/openssl/ -I/home/kwt/openssl/aarch/openssl/include" LDFLAGS="-L/home/kwt/openssl/aarch/openssl/lib" LIBS="-ldl" ./configure --host=aarch64-linux-gnu CC=aarch64-linux-gnu-gcc CXX=aarch64-linux-gnu-g++ --with-ssl --enable-shared --enable-static --disable-dict --disable-ftp --disable-imap --disable-ldap --disable-ldaps --disable-pop3 --disable-proxy --disable-rtsp --disable-smtp --disable-telnet --disable-tftp --disable-zlib --without-ca-bundle --without-gnutls --without-libidn --without-librtmp --without-libssh2 --without-nss --without-zlib --prefix=/home/kwt/curl/aarch/curl

然后执行make和make install生成/home/kwt/curl/aarch/curl。  
修改使用libcurl的例子curl\_test.c的如下内容：

#include "/home/kwt/curl/aarch/curl/include/curl/curl.h"

交叉编译：

aarch64-linux-gnu-gcc curl_test.c  -o  curl_test -L/home/kwt/curl/aarch/curl/lib/ -lcurl

生成可执行文件（丢到开发板测试）。
