用clang补全时出错 about emacs.d

[redguardtoo]

Version of plugins

auto-complete-clang的版本时20120612,我下了个20120730版本的,把auto-complete-clang.el替换了,但是不行,我是个emacs新手,求指点呀

@baby-bear 看看*clang error* buffer的头几行报什么错吧：-）

我感觉是clang-cc1的问题,首先好像没空格,而且编译c++一般好像用clang++,之后我把auto-complete-clang.el中一行 (append '("-cc1" " -fsyntax-only") 改成了 (append '("++ -cc1" " -fsyntax-only") 之后byte-compile-d,可还是不行.出现的错误都一样,而且minibuffer在开始只有一个build目录找不到的小错

@baby-bear clang的介绍页面是这样说的

Note, the -cc1 argument indicates the compiler front-end, and not the driver, should be run.

@brianjcj 原来的elisp上出错信息写得很不好，你如果信得过的话试试我这个吧https://github.com/HongxuChen/dotfiles/blob/master/_emacs.d/site-lisp/auto-complete-clang/auto-complete-clang.el ，出错的话就看echo area或者/tmp/ac-clang-stderr文件

不过我觉得auto-complete-clang响应时间上不行，所以基本上放弃了

use company-clang instead. I don't use auto-complete any more.

I will see to the auto-complete issue this weekend. besides, you know to make auto-complete-clang work in real project, you need manual set up, right?

I created another project cpputils-cmake to do that set up.

if you don't use cmake and cpputils-cmake, you need set upac-clang-flags by yourself.

In one of my project, the value of ac-clang-flags is:
("-I/home/cb/wxWidgets-master/build-release/lib/wx/include/gtk2-unicode-static-2.9" "-I/home/cb/wxWidgets-master/include" "-I/home/cb/projs/dumbway/src/desktop/lua-5.2.1/src" "-I/usr/include/gtk-2.0" "-I/usr/lib64/gtk-2.0/include" "-I/usr/include/atk-1.0" "-I/usr/include/cairo" "-I/usr/include/gdk-pixbuf-2.0" "-I/usr/include/pango-1.0" "-I/usr/include/glib-2.0" "-I/usr/lib64/glib-2.0/include" "-I/usr/include/pixman-1" "-I/usr/include/freetype2" "-I/usr/include/libpng15")

@redguardtoo auto-complete-clang sucks a lot since it uses vanilla clang --code-completion-at and cannot work well for larger projects(the flags issue is a permant headache, neither directory variables nor file local variables work well); there is also a problem with it: you cannot complete the function arguments when you are in template snippets stats. I remembered that the author referenced a lot of code from company-clang beforehand, which might be superior. But I think irony-mode and rtags are more suitable for C++ development. I hope you can have a try and share some customizations:-)

[redguardtoo]

cool, definitely I will try irony-mode

恩，在编辑 .C 文件的时候，当想输入 struct test_stru 来定义一个结构体的时候， 输入到 struct tes 这个位置之后，就会出现这样的错误 /usr/bin/clang-cc1 -fsyntax-only -code-completion-macros -x c -code-completion-at -:2:12 - , clang error buffer 中的内容如下

clang failed with error 1:
/usr/bin/clang-cc1 -fsyntax-only -code-completion-macros -x c -code-completion-at -:5:12 -

<stdin>:1:10: fatal error: 'stdio.h' file not found
#include <stdio.h>
         ^
1 error generated.

如果已经定义了这个结构体，就不会出现这样的错误。

[redguardtoo]

C-h v, check ac-clang-flags.

[notzhan]

应该是在 init.el 中使用了 company-mode 而不是 auto-complete 的原因。

[redguardtoo]

what's your auto-complete plugin?
