找不到emacs和gnutls

我在Ubuntu16.04上构建了emacs26，执行./config --prefix=/usr/local/emacs后显示如下：

configure: error: The following required libraries were not found:
     gnutls
Maybe some development libraries/packages are missing?
If you don't want to link with them give
     --with-gnutls=no
as options to configure

我试图解决这个问题很多次，但是失败了。谁能帮助我，非常感谢。

该错误消息告诉您解决问题的两种方法。

安装gnutls开发包。您可以通过执行以下操作找到它apt-cache search 'libgnutls.*-dev'，然后使用进行安装apt-get。

链接不带gnutls，点./config --prefix=/usr/local/emacs --with-gnutls=no
