.clang_complete does not work

[JMLX42]

Hello,

this plugin looks awesome but I can't get it to work. Whenever I try to toggle the autocomplete, I can an error in the dev console:

Unexpected return code of clang command: 1 autocomplete-clang-view.coffee:141
<stdin>:20:10: fatal error: 'minko/Minko.hpp' file not found
#include "minko/Minko.hpp"
         ^
1 error generated.

So I tried setting up a .clang_complete file in my project root directory:

-I/home/promethe/Projects/minko-beta3/framework/include

But it doesn't change nothing. Yet in the plugin configuration if I set the exact same directory in the "Include Path" field, it works. My guess is the .clang_complete is not handled properly.

Any hint?

Regards,

The problem is in clang-flags, the fix is here: https://github.com/Kev/clang-flags/issues/1

I also don't get my user path to work in the .clang_complete file. Lets say I want to work with Qt

#include <QMainWindow> 

I add the following line into my project .clang_complete file:

-I/Volumes/development/lib/Qt/5.4/clang_64/lib/QtWidgets.framework/Versions/5/Headers

But I still get the error 'QMainWindow' file not found. However I don't get an error in the coffee script file.

Works for me. The .clang_complete file is read for me. I confirmed this by setting a breakpoint in codeCompletionAt: in the result = .. line. Then inspect command + ' ' + args.join(' ') and try to run that command line (you'll see if your settings from .clang_complete are there).

[assemblical]

Yes the file is read, but it doesn't work. I also saw the error now: Unexpected return code of clang command: 1 Let's hope the promethe fix gets involved soon so we can use this plugin.

[dschwen]

There should be a clang error message further up in the console. We need this to figure out the actual problem.

[assemblical]

The developer console in atom doesn't show any clang errors further up.

autocomplete-clang-view.coffee:139 Unexpected return code of clang command: 1
autocomplete-clang-view.coffee:140 <stdin>:5:10: fatal error: 'QErrorMessage' file not found
#include "QErrorMessage"
         ^
1 error generated.

If I run the command directly in my command line:

 clang -fsyntax-only -xc++ -Xclang -code-completion-at=-:72:9 -std=c++11 -I. -I/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/../include/c++/v1 -I/usr/local/include -I/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/../lib/clang/6.0/include -I/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/include -I/usr/include -I/Volumes/developement/lib/Qt/5.4/clang_64/lib/QtCore.framework/Versions/5/Headers -I/Volumes/developement/lib/Qt/5.4/clang_64/lib/QtWidgets.framework/Versions/5/Headers -working-directory=/Volumes/development/projects/src/myproject -

I doesn't respond because of the last - If I remove it and add the input file argument by myself it says

fatal error: cannot locate code-completion file <stdin>
1 error generated.

The option "Ignore Clang Errors" didn't help unfortunately.

[dschwen]

Then don't remove the - but rather do

cat yourinputfile.cpp | clang -fsyntax-only -xc++ -Xclang -code-completion-at=-:72:9 ...

Clang seems to expect input via stdin...

In file included from <stdin>:5:
In file included from /Volumes/development/lib/Qt/5.4/clang_64/lib/QtWidgets.framework/Versions/5/Headers/QErrorMessage:1:
/Volumes/development/lib/Qt/5.4/clang_64/lib/QtWidgets.framework/Versions/5/Headers/qerrormessage.h:37:10: fatal error:
      'QtWidgets/qdialog.h' file not found
#include <QtWidgets/qdialog.h>
         ^
1 error generated.

So it can't find the qdialog header, however it is in the include path. I doubt this is a clang problem as it is working with vim's YouCompleteMe plugin which is also using a clang completion engine.

[dschwen]

If you are running the command outside of atom, as discussed above it indicates this is not a package issue. I'm not familiar with qt anymore but I suggest you search real careful where the missing include file is really located and double check if the include path is correct. I don't see how this could possibly be an issue with the package.

[assemblical]

I copied the flags from my .clang_complete to my .ycm_extra_conf.py and the completion with YouCompleteMe in vim works like a charm. The only difference I can think of is that the additional generated flags differ somehow.

[Kev]

Has this been resolved by the recent changes to clang_flags?

[ssfrr]

I'm not seeing my .clang_complete working here either, but I'm not sure if it's the same issue. I don't see any errors in the console except that it can't find a header file (which my flags should fix). It doesn't seem to load settings from clang_complete, or from the atom.config actually. I'm guessing maybe these got lost in the recent migration to autocomplete-plus integration?

[zlondrej]

Loading .clang_complete actually works fine.

Still, I had a lot of troubles to make autocomplete-clang work, because I didn't add src directory neither into Include Paths field in atom nor into .clang_complete file.

It didn't cross my mind to look into console. After I saw the message I knew what the problem was.

fatal error: 'IEventListener.hpp' file not found
#include "IEventListener.hpp"

I think it would be appropriate to notify user about errors (not warnings).

[uxdxdev]

Can you explain how you included other header files so that autocomplete-clang could find them? So far I have used:

-I/home/mortond/projects/Helium/cocos2d/cocos

This directory contains a cocos2d.h file and is being picked up by autocomplete, BUT the header files inside this one are not being registered. Can I add the header file contents to the autocomplete with something like:

-I/home/mortond/projects/Helium/cocos2d/cocos/cocos2d.h

or

-include /home/mortond/projects/Helium/cocos2d/cocos/cocos2d.h

Any help explaining how I can add other framework header files to the autocomplete would be great.

[engineeror]

Yep autocomplete-clang still can't find headers.

[Sunhick]

Adding include dirs in .clang_complete still doesn't work for me.

[jkuri]

i had to restart atom to get it work.
