Unable to get any completion suggestions (Cygwin) #49

Closed opsound closed 11 years ago

opsound commented 11 years ago

Hi - I am unable to get autocompletion suggestions for anything when I am editing C files in C-mode. I'm using the emacs-w32 package from Cygwin on Windows 7.

(emacs-version)
"GNU Emacs 24.3.1 (i686-pc-cygwin)
 of 2013-03-11 on fiona"

I was able to build it successfully

The llvm-config version I used is:

alex ~/.emacs.d/emacs-clang-complete-async>llvm-config --version
3.1

I have this in my .emacs.d/init.el

;; Emacs Clang Complete Async
(require 'auto-complete-clang-async)
(defun ac-cc-mode-setup ()
  (setq ac-clang-complete-executable "~/.emacs.d/clang-complete")
  (setq ac-sources '(ac-source-clang-async))
  (ac-clang-launch-completion-process)
)

(defun my-ac-config ()
  (add-hook 'c-mode-common-hook 'ac-cc-mode-setup)
  (global-auto-complete-mode t))

(my-ac-config)

(setq ac-clang-flags
      (mapcar (lambda (item)(concat "-I" item))
               (split-string
                "
/cygdrive/c/gcc-arm-embedded/lib/gcc/arm-none-eabi/4.7.4/include
/cygdrive/c/gcc-arm-embedded/lib/gcc/arm-none-eabi/4.7.4/include-fixed
/cygdrive/c/gcc-arm-embedded/arm-non-eabi/include
"
                )))

When I evaluate

ac-sources

with C-x-e in a C-mode buffer, it lists ac-source-clang-async in the minibuffer.

I put the wrong path for 

(setq-ac-clang-complete-executable)
