安装glib库：
configure 配置选项 --enable-debug=no 选项：默认是mini模式，在release的时候应该使用该选项 --disable-included-printf 选项：这个选项要谨慎使用，可能会造成某些 printf 家族的函数不能使用 tar xf glib-2.40.0.tar.xz cd glib-2.40.0 ./configure --enable-debug=no make make install
配置环境变量：
vim /etc/profile
添加下面的内容:
export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig
那就去清华开源站点下载glibc
https://mirrors.tuna.tsinghua.edu.cn/gnu/libc/
在介绍压缩目录里建build，../configure --prefix=/opt/glibc-2.27 make make install
