在Ubuntu下编译VLC源代码生成的VLC无法播放Youtube视频（比如https://www.youtube.com/watch?v=mDp-ABzpRX8）
错误提示如下：
[email protected]:~/vlc-2.1.5$ ./vlc VLC media player 2.1.5 Rincewind (revision 2.1.4-49-gdab6cb5) [0x9872a98] main libvlc: 正在以默认界面运行 vlc，使用 ‘cvlc‘ 将 vlc 运行在无界面的状态下。 [0x9931448] main tls client error: TLS client plugin not available [0xb5d034d8] main input error: open of `https://www.youtube.com/watch?v=mDp-ABzpRX8‘ failed
原因是缺少TLS客户端插件，因此需要将GNUTLS库编译进来。
下载GNUTLS库，最新版本3.3.12，configure时报错，缺少依赖库Libnettle，而且只能适配2.7.1，nettle3.0还不行。
[email protected]:~/gnutls-3.3.12$ ./configure --prefix=/usr configure: error: *** *** Libnettle 2.7.1 was not found. Note that this version of gnutls doesn‘t support nettle 3.0.
又去下载NETTLE库，编译安装，再运行GNUTLS的configure，NETTLE倒是检查通过，但依然报错，还需要HOGWEED库和GMP。
[email protected]:~/gnutls-3.3.12$ ./configure --prefix=/usr .................. checking for NETTLE... yes checking for HOGWEED... no configure: error: *** *** Libhogweed (nettle‘s companion library) was not found. Note that you must compile nettle with gmp support.
下载GMP库，编译安装：How to Install GMP in Ubuntu
下载HOGWEED库，编译安装。
然后，需要重新配置安装NETTLE，可以参考这篇文章（遇到的一模一样的问题及解决方案）。
再再次重新配置编译GNUTLS，
configure正常通过，但make时又报错了，典型的undefined reference to的error问题。
