ubuntu 编译安装curl

https://www.cnblogs.com/suidouya/p/7387861.html

亲测ubuntu16.04安装成功。

步骤

1）下载curl包（可以在这个网站上找最新的版本 http://curl.haxx.se/download/）

wget https://curl.haxx.se/download/curl-7.55.1.tar.gz

2）解压

tar -xzvf  curl-7.55.1.tar.gz

3）覆盖安装

1 cd curl-7.55.1
2 ./configure
3 make
4 make install

4）使用 curl --version 检查是否更新成功

根据这个步骤安装过程中，如出现错误，如下，是因为权限问题，使用sudo make install即可。
