irony mode not working in spacemacs

[pyang-1981]

My spacemacs c-c++ layer package.el looks like this

(setq c-c++-packages '( cc-mode disaster clang-format cmake-mode company (company-c-headers :toggle (configuration-layer/package-usedp 'company)) company-ycmd flycheck gdb-mi ggtags helm-cscope helm-gtags semantic srefactor stickyfunc-enhance ycmd xcscope irony company-irony company-irony-c-headers flycheck-irony ))

(defun c-c++/init-flycheck-irony () (use-package flycheck-irony :defer t ) )

(defun c-c++/post-init-flycheck-irony () (eval-after-load 'flycheck '(add-hook 'flycheck-mode-hook #'flycheck-irony-setup)) )

(defun c-c++/init-irony () (use-package irony :defer t ) )

(defun c-c++/post-init-irony () (spacemacs/add-to-hooks 'irony-mode '(c-mode-hook c++-mode-hook)) (defun my-irony-mode-hook () (define-key irony-mode-map [remap completion-at-point] 'irony-completion-at-point-async) (define-key irony-mode-map [remap complete-symbol] 'irony-completion-at-point-async)) (spacemacs/add-to-hooks 'my-irony-mode-hook '(irony-mode-hook)) (spacemacs/add-to-hooks 'irony-cdb-autosetup-compile-options '(irony-mode-hook)) )

(defun c-c++/init-company-irony () (use-package company-irony :defer t ) )

(defun c-c++/post-init-company-irony () (eval-after-load 'company '(add-to-list 'company-backends 'company-irony)) )

(defun c-c++/init-company-irony-c-headers () (use-package company-irony-c-headers :defer t ) )

(defun c-c++/post-init-company-irony-c-headers () ;; Load with irony-mode as a grouped backend (eval-after-load 'company '(add-to-list 'company-backends 'company-irony-c-headers)) )

When I open a C++ file, the irony mode and company-irony are enabled. However I am only able to get some functions defined by irony, such as irony-get-type, other functions like irony-cdb-compilation-database are not defined. Also, code completion for the most part does not work. Any help is greatly appreciated. The irony version is 1.3.1
