I'm in sync with the latest commit and i recompiled with ./install.sh --clang-completer

Thats the output of the compilation

± ./install.sh --clang-completer                                                                                                                   1.9.3-p448

This is the error that is showed to me when I try to start vim
ycm_client_support.[so|pyd|dll] and ycm_core.[so|pyd|dll] not detected; you need to compile YCM before using it. Read the docs!

The ycm_core.so is found in ./python/ycm_core.so but ycm_client_support.so is not found

[vol0da]

it seems that changing ycm_core to ycm_support_libs at line 80 in install.sh will fix that.

Oops, sorry for the breakage. @vol0da Thanks for tracking this down.

[mikeyjk]

Hey I realise this is from a long time back, but I don't really know where else to put this information in case someone is having the same issue I did.

If you are using neovim and are receiving this error, it is quite possibly because vundle is installing YouCompleteMe into your .vim directory instead of your .nvim directory. Which makes sense in retrospect. Given they are cross compatible, I just rm -r'd the .vim directory, and then made a symbolic link from .vim to .nvim.

[nomasprime]

@mikeyjk just saved me some head scratching, thanks.

[Valloric]

@tarruda @justinmk Why does neovim insist on using an .nvim dir instead of a .vim dir? Seems like it's breaking backwards compatibility with Vim for no reason in this case.

Similar with .nvimrc vs .vimrc; it would make more sense to me to facilitate special neovim configuration in user's vimrc files by making has('neovim') return true in neovim (vim would of course return false for that expression). Users could then use that to use different codepaths for vim & neovim in the same vimrc file.

This would be far more backwards compatible and it would save users tons of pain.

You could even make it so that neovim uses an .nvimrc if present, and if not, uses the .vimrc.

[justinmk]

@Valloric It's kind of a moot point since the plan is to default to XDG layout in the near[ish] future.

by making has('neovim') return true

We do support has('nvim') for that case.

However, we can add a sanity check (with a passive warning) if .nvim{rc} is missing but .vim{rc} is present.

[justinmk]

You could even make it so that neovim uses an .nvimrc if present, and if not, uses the .vimrc.

That would not have helped in @mikeyjk's case, because (if I'm not mistaken) he had a _copy_ of his plugins in .nvim. Otherwise he would have noticed that vundle was using the wrong &rtp since _none_ of his plugins would be working....

[nomasprime]

Would definitely help - atm I'm using separate manifests in my boxen provisions to be on the safe side.

[tarruda]

However, we can add a sanity check (with a passive warning) if .nvim{rc} is missing but .vim{rc} is present.

We can use an approach similar to waht zsh does: If .nvimrc is missing, display a warning/prompt offering to create an empty file avoid future warnings

[Valloric]

We do support has('nvim') for that case.

Yay! :)

It's kind of a moot point since the plan is to default to XDG layout in the near[ish] future.

Could you elaborate on this? If you could provide a link to some docs/an issue where I could read more about this plan, that would be great.

The point I'm trying to get across is that in an ideal world, someone running vim could just run nvim and their vim configuration mostly works out-of-the-box in neovim. I'm sure some breaking changes might be necessary, but such breakage would be best avoided if at all possible.

Neovim could then have a different system of configuration with the old .vimrc/.vim folder being deprecated but still supported for the sake of backwards compatibility.

As a case in point, YCM used to run all completers directly in the Vim process. Last year I split the vast majority of YCM logic into the separate ycmd server, with a thin Vim client that now talks to that server. It was a _huge_ endeavor that affected the entire codebase, and yet the vast majority of users were completely unaware that it happened because the new setup was almost entirely backwards compatible with the old one.

I'd personally love it if the vim -> neovim transition could be that painless since it would mean more users switching over. I want neovim to succeed _so much!_

@Valloric XDG discussion: https://github.com/neovim/neovim/issues/78

in an ideal world, someone running vim could just run nvim and their vim configuration mostly works out-of-the-box in neovim

I think it's optimizing for what is intended to be a very temporary situation. We don't want to optimize for "flirtation". Ultimately people should not need to flirt with Neovim _and_ Vim. They should only need to pick one.

I'm sure some breaking changes might be necessary, but such breakage would be best avoided if at all possible.

We tried that with VIMRUNTIME, etc., but it causes a lot of pain and confusion when things "mostly work", yet some things don't.

I'd personally love it if the vim -> neovim transition could be that painless since it would mean more users switching over.

I think the sanity checks will go a long way for little cost.

@Valloric Sorry, i always got the problem that "ycm_client_support.[so|pyd|dll] and ycm_core.[so|pyd|dll] not detected;".

I just found the ycm_client_support.cpp and ycm_core.cpp :1234:

Alright, my mistake. I miss the step that './install.sh --clang-completer'. :+1:

cd ~/.vim/bundle/YouCompleteMe
./install.py

Fix this problem for me, i have Ubuntu 14 as OS and CMake installed, previously..

I hope they serve ..

Regards.-
