Wrong working directory leading to clang errors

[nafur]

When I try to autocomplete in a file (say /home/user/project/test.h), the clang commandline looks like this:

clang++ -fsyntax-only -xc++ -Xclang -code-completion-at=-:97:19 -std=c++11 -I. -std=c++11 -working-directory=/home/user -

In my case, the file contains an include to another file in the same folder.
However, due to -working-directory=/home/user, clang is unable to locate this file.

I'd really like to use this plugin, but this error persists.
I tried to craft a patch fixing this bug, which turned out to basically remove the try block in buildClangArgs.

However, I hit another problem then: When completing in a header file, clang complains about having #pragma once in the main file and refuses to give any completions.
This can be fixed by using echo "#include \"filename.h\"" | clang++ instead of cat filename.h | clang++, i.e. simply changing the input option in codeCompletionAt().
This however requires that the file is actually saved before performing autocompletion...

I've just looked into this, as I'm affected this bug as well. The issue lies in the "clang-flags" package, which always adds a -working-directory=#{searchDir} parameter to the clang call, where searchDir is the directory of the .clang_complete file. I think this should be fixed in clang-flags, but workarounding it in autocomplete-clang would also be easy.

I've opened Kev/clang-flags#11 . In the mean time, the following fixes the issue for me:
