deoplete-clang get errors #59

andrea993 · 2016-10-13T21:21:19Z

Deoplete-clang doesn't work I get this error when it should complete the cpp syntax:

[deoplete] Could not get completions from: clang.  Use :messages for error details.

:messages says:

zchee · 2016-10-14T01:37:11Z

@andrea993 Thanks issue :)

Hmm.. I have not yet debug, will check it.
Sorry, if you have time, could you post a sample C source at occurring this problem?

andrea993 · 2016-10-14T07:48:03Z

I have this issue with all .cpp files

#include <iostream>

using namespace std;

int main()
{
    std::
}

If. for example. I go at the end of std:: and I press a to write I get the error

zchee · 2016-10-14T08:04:37Z

@andrea993 I think your problem same as #54
That's not yet merged, but Could you try it?

Shougo · 2016-11-30T23:20:57Z

@andrea993

Please upload the compilation database file.
I cannot get your init.vim. Please upload it to another place.

parnmatt · 2016-12-04T15:27:52Z

Rather than creating another issue, this issue seems to be similar if not the same.

I do not know what the compilation database file is, @Shougo, where would this file be located?

Minimal init.vim

The test file I used was:

As typing the d in std the following errors were printed to :messages

Shougo · 2016-12-04T15:30:51Z

I do not know what the compilation database file is, @Shougo, where would this file be located?

Hm. It is not specified.
We should improve the error message.
But where is your libclang installed?
I think you need to set it like this.

let g:deoplete#sources#clang#libclang_path = '/usr/lib/libclang.so'

parnmatt · 2016-12-04T20:09:25Z

Indeed, libclang is located, and symlinked to /usr/lib/libclang.so -> libclang.so.3.9.

This is a standard place for the library to be located, and certainly should be in the library path.
Why wouldn't this be found by neovim / deoplete-clang?

I will try the minimal configuration with the path hardcoded as suggested and get back to you.

Shougo · 2016-12-04T23:37:44Z

This is a standard place for the library to be located, and certainly should be in the library path.
Why wouldn't this be found by neovim / deoplete-clang?

Unfortunately, it is not standard.
This is for Ubuntu 16.04 configuration.

let g:deoplete#sources#clang#libclang_path = '/usr/lib/llvm-3.8/lib/libclang-3.8.so'

parnmatt · 2016-12-07T20:35:15Z

Yep correcting this has solved my issue.
I correctly pointed libclang_path and clang_header to the correct paths.

However the moment I start typing #include it freezes (I assume looking for headers to complete; and uses ) for 5-10; and does so whenever I edit on that line.

Shougo · 2016-12-07T22:38:09Z

Yes, deoplete-clang has many performance problems.
But it will be fixed by @zchee .

Cypher1 · 2016-12-09T07:27:48Z

I'm also having a similar problem, can we just get deoplete-clang to ignore lines that start with '#'?

(or have an option for that)

kierun · 2016-12-19T11:21:10Z

I have the same issue (I think?) but setting libclang_path and clang_header did not solve it. The really weird thing is that after the error, completion works just fine.

Is there something I can try to provide you with more debug information?

sshtmc · 2017-03-06T15:39:33Z

I have the same problem. Any update on the issue?

Shougo · 2017-03-08T23:03:59Z

You should use deoplete-clang2 instead.

https://github.com/tweekmonster/deoplete-clang2

Cypher1 · 2017-03-08T23:25:46Z

Why is there a second deoplete rather than a second version?

Shougo · 2017-03-08T23:32:11Z

Because, @zchee implements the new version of deoplete-clang.
He is very busy. No time to fix the bugs in deoplete-clang currently.

Cypher1 · 2017-03-09T02:25:58Z

Hmm, fair enough, couldn't we just have branches to facilitate visibility and merging?

Deoplete is an awesome plugin, I'd hate to see two parts diverge and end up with incompatible features.

sshtmc · 2017-03-09T07:41:11Z

@Cypher1 I think there's a misunderstanding (from the eyes of a complete outsider). Deoplete is a separate project from deoplete-clang. Deoplete stays as is. However, deoplete-clang had too high code complexity (it seems) and now there's going to be deoplete-clang2.

But regardless of the above, I would also like to see deoplete-clang2 replace deoplete-clang (become version 2). IMHO there's no point in having deoplete-clang if it's full of bugs and nobody is maintaining it.

kierun · 2017-03-09T07:43:55Z

This is going to add to the confusions of users unless someone actually write this on the main README…

sshtmc · 2017-03-09T09:11:47Z

I just tried deoplete-clang2 (https://github.com/tweekmonster/deoplete-clang2) and it worked great, without any issues.

I like deoplete-clang than deoplete-clang2.
deoplete-clang will be rewritten.

AnisPeysieux · 2017-04-07T23:48:02Z

Hi!
I have the same problem. My PC is on Debian testing.
My libclang is at /usr/lib/llvm-3.8/lib/libclang.so.
I tried deoplete-clang2 but I get errors too, even if I write let g:deoplete#sources#clang#executable='/usr/bin/clang', let g:deoplete#sources#clang#executable='/usr/bin/clang2' or let g:deoplete#sources#clang#executable='/usr/bin/clang-3.8'.

Have you an idea?

Thanks.

Shougo · 2017-04-09T14:06:03Z

I tried deoplete-clang2 but I get errors too, even if I write let

You should create new issue in deoplete-clang2.
