vim - Cant Get NeoComplCache in GVim on Ubuntu -

i have installed gvim on ubuntu computer , after adding necomplcache files vimfiles adding let g:neocomplcache_enable_at_startup = 1 .vimrc, still not getting popup autocompletion in gvim. tried execute :neocomplcacheenable , "not editor command".

i new using gvim on ubuntu , did same thing in windows , works fine on windows. tried autocomppop , couldnt work in ubuntu either.

do these plugins work in ubuntu gvim?

are there other options autocompletion in gvim in ubuntu?

i changed directory plugins vimfiles .vim , seemed fix problem.
