解决omnicppcomplete显示”pattern not found”

  其实是tags文件有问题，确切说是生成tags文件时，使用的命令行参数有问题。

  我最开始这样：ctags -R -f ~/.vim/tags/c 。很好笑吧，我就为它折腾了半个下午。

  是在google上看了一篇帖子，改成：ctags -R -f ~/.vim/tags/c  --C-kinds=+p --fields=+aS --extra=+q就好了。

  原帖答案贴过来（是他自问自答）：

I found the problem.

My tags file is NOT Ok as I thought.

Incorrect version generated with:

ctags -R --C-kinds=+p --field=+S

This generates this tags file:

-bash-3.2$ cat tags

!_TAG_FILE_FORMAT 2 /extended format; --format=1 will not append ;" to lines/

!_TAG_FILE_SORTED 1 /0=unsorted, 1=sorted, 2=foldcase/

!_TAG_PROGRAM_AUTHOR Darren Hiebert /[hidden email]/

!_TAG_PROGRAM_NAME Exuberant Ctags //

!_TAG_PROGRAM_URL http://ctags.sourceforge.net        /official site/

!_TAG_PROGRAM_VERSION 5.8 //

a f1.h /^ int a; $/;" m struct:mystruct

b f1.h /^ int b;$/;" m struct:mystruct

main f1.c /^void main (void)$/;" f signature:(void)

myType f1.h /^} myType;$/;" t typeref:struct:mystruct

mystruct f1.h /^typedef struct mystruct {$/;" s

-bash-3.2$

tags that works for this particular example were generated with:

ctags -R --C-kinds=+p --fields=+aS --extra=+q

-bash-3.2$ cat tags

!_TAG_FILE_FORMAT 2 /extended format; --format=1 will not append ;" to lines/

!_TAG_FILE_SORTED 1 /0=unsorted, 1=sorted, 2=foldcase/

mystruct f1.h /^typedef struct mystruct {$/;" s

mystruct::a f1.h /^ int a; $/;" m struct:mystruct access:public

mystruct::b f1.h /^ int b;$/;" m struct:mystruct access:public

-bash-3.2$

The help file in omniCppComplete plugin (in .vim/doc/ folder) calls for:

ctags -R --c++-kinds=+p --fields=+iaS --extra=+q .

I had assumed that since I am not using C++ (simply C), that the +ia in --fields and +q in --extra would be irrelevant.

Thanks
