debian下需要安装apt安装下clang和llvm
sudo apt-get install llvm-dev sudo apt-get install libclang-dev
网上抄来一个大神的配置
~/.emacs.d/el-get-user/recipes/clang-complete-async.rcp
1 (:name clang-complete-async 2 :website "https://github.com/Golevka/emacs-clang-complete-async" 3 :description "An emacs extension to complete C and C++ code using libclang." 4 :type github 5 :pkgname "Golevka/emacs-clang-complete-async" 6 :build '(("make")) 7 :depends auto-complete 8 :features auto-complete-clang-async 9 :prepare (setq ac-clang-complete-executable 10 (expand-file-name 11 (concat (el-get-package-directory "clang-complete-async") "clang-complete"))))
emacs，alt+x,执行el-get-install,输入clang-complete-async
在~/emacsConfig下建立clang-complete-async-setting.el
