Question

我正在尝试为c ++编程设置emacs。大部分都遵循此处的说明.. http://truongtx.me/2013/03/10/emacs-setting-up-perfect-environment-for-cc-programming/ 一切都很好，除了我遵循指示的自动完成 http://truongtx.me/2013/03/06/emacs-ccpp-autocomplete-with-clang/

根据说明，[C-]应该绑定，但是当我按[ctrl +' - ']时，我看不到任何建议.. 这是我的.emacs文件

Answer 1

您ac-complete-clang已绑定到C-`，而不是C--;如果用正确的bindng触发它，它应该可以工作。

正如the troubleshooting section of auto-complete-clang's README中所述，您可能需要在系统库中手动指向auto-complete-clang：

clang无法找到标准的inlcude文件？

这是因为clang的包含文件搜索路径不正确。这是解决方案：

找出g ++的包含文件搜索路径：

echo "" | g++ -v -x c++ -E -

你会得到这样的东西：

#include "..." search starts here：
#include <...> search starts here：
 /usr/include/c++/4.6
 /usr/include/c++/4.6/x86_64-linux-gnu/.
 /usr/include/c++/4.6/backward
 /usr/lib/gcc/x86_64-linux-gnu/4.6.1/include
 /usr/local/include
 /usr/lib/gcc/x86_64-linux-gnu/4.6.1/include-fixed
 /usr/include/x86_64-linux-gnu
 /usr/include
End of search list.

设置ac-clang-flags以包含这些默认包含的pathes。如，

(setq ac-clang-flags
      (mapcar (lambda (item)(concat "-I" item))
              (split-string
               "
 /usr/include/c++/4.6
 /usr/include/c++/4.6/x86_64-linux-gnu/.
 /usr/include/c++/4.6/backward
 /usr/lib/gcc/x86_64-linux-gnu/4.6.1/include
 /usr/local/include
 /usr/lib/gcc/x86_64-linux-gnu/4.6.1/include-fixed
 /usr/include/x86_64-linux-gnu
 /usr/include
"
               )))

您可以将其放入.emacs文件中。

然后代码完成工作正常！
