安装开发包

sudo yum groupinstall "Development Tools" # 一口气安装编译时所需的一切工具
sudo yum install ncurses-devel #必须这样才能让 make *config 这个指令正确地执行。
sudo yum install hmaccalc zlib-devel binutils-devel elfutils-libelf-devel #创建 CentOS-6 内核时需要它们

执行安装 brew install dnscrypt-proxy brew cask install dnscrypt

会卡在这里

	;; An (imaginary) actor macro takes an initial state and callback fns.
	;; (actor {} (fn1 [state message]) (fn2 [state message) ...)

	;; The most obvious callback fn is (receive [state message) that is called when a
	;; message is consumed from the agents mailbox. receive is called with the old state
	;; and the message as parameters -- it returns the new state.
	;; sender is bound to the senders pid.

	;; other callbacks are stuff broken link detection etc.
