So irony-mode scans include directories through a file called .clang_complete, which looks like something like: -I./include/

However, it does not automatically load this file. Rather, I have to go into the source file and call irony-cdb and then load it manually by hitting l. I tried:

(add-hook 'c++-mode-hook 'irony-cdb-load-compile-options)

But it did not do anything. In fact, irony-mode wouldn't work period. I am trying to use irony-mode as a company-mode backend.

Q: How would I make this process automatic?

You have to use a more recent version of irony-mode to have automatic loading. This feature is supported since irony-mode's version 0.2.0-cvs. M-x irony-version to know you version.

To load the compile options manually the method has changed, you can call the interactive function irony-cdb-autosetup-compile-options manually: M-x irony-cdb-autosetup-compile-options RET.

To make this process automatic, you only need to add call this function automatically when irony-mode is enabled. This is easily done with a the add-hook function:

In your irony-mode configuration add:

(add-hook 'irony-mode-hook 'irony-cdb-autosetup-compile-options)
