Paths from -I command line don't seem to be searched?

[wberrier]

Turns out it does work as long as I run:

company-irony-c-headers-reload-compiler-output

for every file I open.

Am I doing something wrong? Should I be adding an open buffer hook to call the above for every file?

[hotpxl]

This should happen automatically. Could you print company-irony-c-headers--compiler-output before and after the call and see if there is a difference in the parsed compiler options?

I have same problem. Before company-irony-c-headers--compiler-output is nil however after i run company-irony-c-headers-reload-compiler-output the value of it becomes

I think this value is correct.
Do you have any idea?

[hotpxl]

@frostedpenguin This behavior is correct. If you look at this function, every time compiler-output is nil, reload is called. So when you are doing auto completion, it fetches the include paths, and then would call this function if the search path is nil.

[hotpxl]

@frostedpenguin Is your project path included in the output strings? What does your project structure look like?

[lazysquid]

@hotpxl hmmm i see. I think it should work but I don't know why it's not working.
I was reading this code https://github.com/mmp/pbrt-v3. I generate compile_commands.json using Cmake so i guess the path is included in output strings. Because whenever I applied M-x company-irony-c-headers-reload-compiler-output manually, company-irony-c-headers parse my project headers really nicely

[lazysquid]

@hotpxl I figured out the problem
It was hook problem of Company-mode
(use-package irony
:ensure t
:init
(add-hook 'c++-mode-hook 'irony-mode)
(add-hook 'c-mode-hook 'irony-mode)
(add-hook 'irony-mode-hook 'my-irony-mode-hook)
(add-hook 'irony-mode-hook 'company-irony-setup-begin-commands)
(add-hook 'irony-mode-hook 'irony-cdb-autosetup-compile-options))
this is my irony-mode setup and

(use-package company
:ensure t
:init
(add-hook 'prog-mode-hook 'company-mode)
:config
(setq company-idle-delay 0.02)
(setq company-minimum-prefix-length 1)
(setq company-show-numbers t)
(setq company-selection-wrap-around t)
(setq company-transformers '(company-sort-by-occurrence company-sort-by-backend-importance))
(setq company-tooltip-limit 20)
(setq company-dabbrev-downcase nil)
(setq company-dabbrev-ignore-case t)
(setq company-dabbrev-code-ignore-case t)
(setq company-dabbrev-code-everywhere t)
)

and this was my original Company-mode setup. I thought c and c++ mode hook is part of prog-mode-hook but it's different.. so I have changed it to
(use-package company
:ensure t
:init
(add-hook 'prog-mode-hook 'company-mode)
(add-hook 'c-mode-hook 'company-mode)
(add-hook 'c++-mode-hook 'company-mode)
:config
(setq company-idle-delay 0.02)
(setq company-minimum-prefix-length 1)
(setq company-show-numbers t)
(setq company-selection-wrap-around t)
(setq company-transformers '(company-sort-by-occurrence company-sort-by-backend-importance))
(setq company-tooltip-limit 20)
(setq company-dabbrev-downcase nil)
(setq company-dabbrev-ignore-case t)
(setq company-dabbrev-code-ignore-case t)
(setq company-dabbrev-code-everywhere t)
)

and it works great.
Thanks @hotpxl

Glad you figured it out. :)
