I have recently installed YouCompleteMe and can't figure out how to disable its error checking feature. I am developing in C++ and wanted to use Neomake as my checker.

1 Answer 1


The g:ycm_show_diagnostics_ui variable controls this:

The *g:ycm_show_diagnostics_ui* option

When set, this option turns on YCM's diagnostic display features. See the
_Diagnostic display_ section in the _User Manual_ for more details.

So, do:

let g:ycm_show_diagnostics_ui = 0
