TranslationUnitLoadError

[covercash2]

Problems summary

just trying to get autocomplete with neovim.

from neovim :messages : http://pastebin.com/d48cuBTR

this is very similar to #59, but that seems to be solved with setting the right clang paths, which I think I have set correctly in my init.vim (this is minimal, but confirmed): http://pastebin.com/MPHVLRD1

I've installed llvm/clang with homebrew and had the same problem, but my current llvm I compiled into my home tree.

I get the same behavior as #59 where I type std and deoplete-clang goes nuts. also happens with sf (SFML).

Expected

autocomplete

Environment Information

• OS: macOS 10.11.6
• Neovim version: 0.1.7

reproduce

1. install neovim
2. run my init.vim using plug, deoplete, and deoplete-clang, also setting libclang and clang headers path
3. try to write c/c++
4. chain smoke and cry

logfile

I generated this logfile: http://pastebin.com/dakv1Seu

conclusion

let me know if you need anything else or about any work-arounds

[ghost]

I have the same problem.

@covercash2 @stjepang You should read README.md carefully. g:deoplete#sources#clang#libclang_path and g:deoplete#sources#clang#clang_header are needed to work this plugin.

sry 😢

example (tested with Arch Linux)

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

here's the same init file i originally posted. also, this issue was only on macOS.

i tried to be thorough in my original report.

I think it depends clang version.
Using deoplete-clang2 is recommended.

I get same errors:

Sometimes it was just a matter of removing the translation unit file again. (The .tu file) And it all works again.
