Syntastic: Unknown function: SyntasticStatuslineFlag

[yusijs]

I'm unable to use the awesomeness that is Syntastic because of this error. My vim install is fine according to the requirements, so I'm kind of at a loss about what my issue is.

Error messages:

E117: Unknown function: SyntasticStatuslineFlag

E15: Invalid expression: SyntasticStatuslineFlag()

Your installation is broken: syntastic is not yet loaded at the time Vim gets to see the set statusline line. This is not a problem with syntastic. It might be a bug in NeoBundle (perhaps related to lazy loading), a problem in your vimrc, or something else entirely. You could try to debug it by adding set runtimepath just before set statusline+=%{SyntasticStatuslineFlag()} and looking at the output (syntastic should be listed there).

I see this is closed however I ran into this problem and the solution was to make sure powerline-status was installed. YMMV..

[lcd047]

@edrolo-paulm Then your installation is broken even worse. As noted in the manual, you aren't supposed to add set statusline+=... to your vimrc if you're using powerline:

Please note that __these settings might conflict with other Vim plugins that change the way 'statusline' works__. Refer to the syntastic-compatibility notes below and to the respective plugins' documentation for possible solutions.

In particular see syntastic-airline below if you're using the "airline" Vim plugin (https://github.com/vim-airline/vim-airline). See syntastic-flagship if you're using "flagship" (https://github.com/tpope/vim-flagship). See also syntastic-powerline if you're using the "powerline" Vim plugin (https://github.com/powerline/powerline).

I had this problem after moving my .vimrc to a different machine. Removed the following line: set laststatus=2 fixed it.

Disregard my last comment. My .vim/bundle directory got blown away during some git hiccup.
