After downloading YouCompleteMe from ubuntu repositories and installing it I have used this script as extra config. I suppose this config may help me with in-headers functions auto-completion.

:YcmDebugInfo shows

    Printing YouCompleteMe debug information...

Currently the problem is that plugin doesn't complete functions from headers, only from current file. I spent several hours but still have no idea how to fix this, need help.

    Probably you're best asking the YCM devs. None of the error text means much to me, though it might to folks who use the plugin. (PS Guessing that the config helps with a particular thing is probably a poor way to go—you may want to read the docs for the plugin and find out how to configure it to use headers. Vim can natively complete from included files with <C-x><C-I> see :help compl-keyword if configured to detect and find includes correctly.)

  • @D.BenKnoble very nice, that is enough, you can post this as an answer if you wish. Thank you. Jul 27 at 18:43

Not a YCM answer, but Ctrl-x Ctrl-i will complete from included files, assuming path/include/etc. are configured correctly. See :help compl-keyword for more.
