I am building libfzf.dll like this:

gcc -O3 -Wall -Werror -fpic -shared src/fzf.c -o build/libfzf.dll

gcc --version output:

I am currently stuck with this issue!

The first thing i notice is that i am not using the correct separator for windows but i dont think this is the issue here because i had people report that everything is working.
I am not much of a help when it comes windows because i dont own a windows device. If you find some time it would be cool if you could me @l-kershaw :) thanks

Hi @sametaylak, I won't pretend to fully understand what goes on in telescope-fzf-native.nvim, but a couple of things that I wanted to check:

• You give the command that you are using to compile the build. Are you typing this yourself, or are you using the makefile?
• Your gcc is from 2016, have you tried updating it?
• Does the build create a .dll file where you would expect?

Also, for completeness, could you provide a copy of your configuration as it pertains to telescope.nvim and telescope-fzf-native.nvim (both for installing the plugins and the setup and load_extension calls)?

[sametaylak]

First answer: I am typing myself.
Second answer: I haven't. I used mignw-get-setup.exe for installing gcc.
Third answer: Yeah, It is creating a .dll file called libfzf.dll.

Vim plugins:

call plug#begin('~/.vim/plugged')

Plug 'neoclide/coc.nvim', {'branch': 'release'}

Plug 'junegunn/fzf', { 'do': { -> fzf#install() } }
Plug 'junegunn/fzf.vim'


Plug 'nvim-lua/popup.nvim'
Plug 'nvim-lua/plenary.nvim'
Plug 'nvim-telescope/telescope.nvim'
Plug 'nvim-telescope/telescope-fzf-native.nvim', { 'do': 'make' }

Plug 'fannheyward/telescope-coc.nvim'

call plug#end()

Telescope setup in the end of init.vim file

lua << EOF
require('telescope').setup {
  extensions = {
    fzf = {
      fuzzy = true,                    -- false will only do exact matching
      override_generic_sorter = false, -- override the generic sorter
      override_file_sorter = true,     -- override the file sorter
      case_mode = "smart_case",        -- or "ignore_case" or "respect_case"
                                       -- the default case_mode is "smart_case"
    }
  }
}
-- To get fzf loaded and working with telescope, you need to call
-- load_extension, somewhere after setup function:
require('telescope').load_extension('fzf')
require('telescope').load_extension('coc')
EOF

Maybe this could help https://stackoverflow.com/a/17873843 gcc -m32 i think or maybe you need a 64bit gcc. Dont know which way around

I fixed this issue with msys2 installation.
