由于系统上次安装的wget版本过低，所以需要升级wget。这里主要记录一下要安装的依赖库文件。

1、下载源文件

Index of /gnu/wget

2、环境检测

./configure

报错：
 

checking for zlib... yes
checking for gnutls... no
configure: error: Package requirements (gnutls) were not met:

No package 'gnutls' found

Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.

Alternatively, you may set the environment variables GNUTLS_CFLAGS
and GNUTLS_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.

安装依赖lib

yum install gnutls-devel

3、编译安装

make && make install

4、换旧版本的wget换成新版本

mv /usr/bin/wget /usr/bin/wget.112

ln -s /usr/local/bin/wget /usr/bin/wget

wget --version

GNU Wget 1.25.0 在 linux-gnu 上编译。
