Symbol’s function definition is void: irony-completion-candidates-async

[pivorics]

Hi,

I am currently using the latest version of doom emacs (26.1). I was trying to get autocompletion in C++ work but nothing popped up as I typed. I have made sure irony server is installed, and have llvm and cmake installed using homebrew. I toggled on the debugging error and ran M-x counsel-irony, and it showed the following:
(void-function irony-completion-candidates-async)
irony-completion-candidates-async(counsel-irony-callback)

How should I go about debugging this? Thank you!
