No package 'gnutls' found 解决办法

安装libosmocore的时候, 执行下面的操作, 发现会报错

$ ./configure 

报错如下

configure: error: Package requirements (gnutls >= 2.12.0) 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 LIBGNUTLS_CFLAGS
and LIBGNUTLS_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details. 

这个时候 执行下面的语句可以解决这个问题

$  sudo apt-get install libghc-gnutls-dev
