      Hi,
      I am trying to get autocompletion working for C files, specifically for structure members.

      I installed OmniCppComplete plugin.
      I get "-- Omni completion (^O^N^P) Pattern not found" after I type the "." for a struct variable "foo" as shown below.
      I am using vim 7.3 and exuberant ctags 5.8.


      -bash-3.2$ cat ~/.vimrc
      " This is a comment

      syntax on
      set path=**
      set tabstop=4
      set number

      " omnicppcomplete
      set nocp
      filetype plugin on
      -bash-3.2$



      -bash-3.2$ ls
      f1.c f1.h tags
      -bash-3.2$


      -bash-3.2$ cat f1.h
      typedef struct mystruct {
      int a;
      int b;
      } myType;


      -bash-3.2$ cat f1.c
      #include "f1.h"

      void main (void)
      {
      myType foo;
      foo. <-- as soon as I type the ".", I get Pattern not found!
      }

      My tags file looks OK to me with the typedef and structure members, etc.
      omnicppcomplete must be working since as soon as I type ".", I get pattern not found (I don't even need to type C-x C-o).
      It is not the "typedef" that is causing me the problem because I have the same problem without it as well (struct mystruct { int a; int b; }; etc).

      Any idea how to debug this further? or what is wrong?

      Thanks

        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/

        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/

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

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