最近使用ubuntu14.04，搭配gitlab出现此gnutls_handshake() failed: Handshake failed问题，一直未能解决，直到找到本文的脚本，修正编译错误后，终于得以解决。记录一下，分享给大家。

错误提示

fatal: unable to access 'https://192.168.31.187/aw/android.git/': gnutls_handshake() failed: Handshake failed

错误原因

• git工具默认使用gnutls包进行网络加密传输，但在特殊情况下（如使用了代理服务器）gnutls会出现奇怪的问题，我们可以使用更稳定的openssl包来代替gnutils的功能。
• 只有在低版本Ubuntu 14.04上遇到此问题，其余版本20.04及以上未有遇到

解决方法

• 如下，直接使用此脚本，已在原版上增加CFLAGS=-std=gnu99，亲测OK
