Hi, the following messages appeared when I tried to build Irony version 1.0. In general, I did not have any problem to build irony in visual studio until version 1.0. I am using CMake 3.8.1 in order to be able to target MSVC 2017.

Thank you for your help.

Here is the error messages i have when I tried to irony-in stall-server. I am currently using Mac OS v10.9.5, with cmake version 3.0.0 and LLVM built from brew.

Thanks Chester

Hello.

In addition to auto-completion features, libclang supports source code indexing and AST traversing. Emacs has its own C++ parser (in semantic) that works quite slow and is not perfect (e.g., 'jump to definition' is very slow not always accurate for me).

And since both semantic and irony-mode are extensible, it's possible to write irony-mode plugin that will provide (hopefully) fast and reliable C++ back-end for semantic.

So is there already some work in progress? If not, I'm going to start working on it. Would you like such plugin to be in main irony-mode repository?

For now I have proof-of-concept standalone program that parses C++ code using libclang and prints elisp expression that is similar to (semantic-parse-region) output (but it is yet incomplete).

proof-of-concept program example input example output

I am attempting to build the irony server. The command fails outright within Emacs and attempting to build manually from the command line, I receive the following error message:

-- C++11 compiler option(s): -std=c++11 CMake Error at /usr/local/Cellar/cmake/3.1.0/share/cmake/Modules/FindPackageHandleStandardArgs.cmake:138 (message): Could NOT find LibClang (missing: LIBCLANG_LIBRARY LIBCLANG_INCLUDE_DIR) Call Stack (most recent call first): /usr/local/Cellar/cmake/3.1.0/share/cmake/Modules/FindPackageHandleStandardArgs.cmake:374 (_FPHSA_FAILURE_MESSAGE) cmake/modules/FindLibClang.cmake:78 (find_package_handle_standard_args) src/CMakeLists.txt:3 (find_package)

I have XCode6 installed in addition to clang through brew. The missing library libclang.dylib appears at /usr/local/opt/llvm/lib as installed by brew, additionally within /Applications through XCode. Clearly the cmake is simply not recognizing the installation. Can anybody provide any advice?

Hello,

First of all I would like to thank you for making irony-mode. It seems like a really nice package that greatly enhances the C/C++ editing experience.

I am an rtags user, but wanted to combine it with irony mode so as to get nice completions. Thus I tried to use company mode and company-irony. I obtained the packages from el-get. My setup is as follows:

init-irony-mode.el:

(add-hook 'c++-mode-hook 'irony-mode)
(add-hook 'c-mode-hook 'irony-mode)
(add-hook 'objc-mode-hook 'irony-mode)

;; replace the `completion-at-point' and `complete-symbol' bindings in
;; irony-mode's buffers by irony-mode's function
(defun my-irony-mode-hook ()
  (define-key irony-mode-map [remap completion-at-point]
    'irony-completion-at-point-async)
  (define-key irony-mode-map [remap complete-symbol]
    'irony-completion-at-point-async))
(add-hook 'irony-mode-hook 'my-irony-mode-hook)
(add-hook 'irony-mode-hook 'irony-cdb-autosetup-compile-options)

init-company-irony.el

(eval-after-load 'company
  '(add-to-list 'company-backends 'company-irony))

;; (optional) adds CC special commands to `company-begin-commands' in order to
;; trigger completion at interesting places, such as after scope operator
;;     std::|
(add-hook 'irony-mode-hook 'company-irony-setup-begin-commands)

Nothing fancy. Just what the wikis say. I also got (add-hook 'after-init-hook 'global-company-mode) somewhere so that I activate company mode.

I am using json compilation databases for all of my projects. I use a package that I have created to act as a glue between other emacs packages and create the json compilation database. I know that the database is valid since rtags server gets it as input and correctly navigates the projects.

So I have this json compilation named compile_commands.json in the root of the project. I suspect that irony mode actually reads it since I see something that looks like the whole project's compile flags, include directories and files when I execute irony-cdb-menu.

But the problem is that whenever I try to use any autocomplete or anything at all, all I get is an error message:

error in process filter: irony-completion-at-point: Wrong type argument: sequencep, libclang:

I also tried to describe the current company backend variable and it seems to be nil. This is funny because company-backends list has company-irony as the first one in the list. I tried to insert company-irony as the only element of company-backends but I got the same result.

While debugging I tried to remove (add-hook 'irony-mode-hook 'irony-cdb-autosetup-compile-options) from the setup. Then completion popup actually appeared but it was totally random. Seemed to have no proper source. Could the issue be with the way that irony autodetects the compilation database?

Do you have any idea what may be happening? IF you need any more information about my setup I will gladly provide.

I'm interested to use irony-mode in Windows, do you have a more detailed tutorial? please. Thank you.

I try with MinWG and the Guide Wiki

But I get message..

"Standard library doesn't support C++11!"

Thank You So Much.

closes #234, #236 maybe some issues linked there as well.

First, now looks recursively for parents for both ".json" and "build/.json". (#234)

Second, #236. One confusing bit is that calling irony-cdb-json-add-compile-commands-path doesn't actually finish by loading the database you added. That might be "Cleaner", but its inconvenient and under-documented. Commit 2 fixes that.

Third, still #236, I was led astray by add-compile-commands-path asking for both project root and cdb path and ended up choosing the build directory, then the file within it. I may not have been paying enough attention, but the issues suggest I may not be the only one. So, commit 3 adds an alternative which takes only a cdb path, loads it, and uses the source file paths in it to find the project root as the deepest dir parenting everything in the cdb. I would have just replaced add-compile-commands-path entirely, but that's public and the new function takes one argument less. If you like the idea and don't mind breaking the API, go for it.

Please review/test, I only wrote it, I haven't actually tested it (much) :)

If you merge 1m my problem is basically solved. 2 I think is reasonable. 3 was just frustration.

I want to test irony. But I have the following error:

irony-server is broken, good luck buddy! /home/username/.emacs.d/irony/bin/irony-server exited with status 127

Any ideas?

Hello everyone.

So, I've successfully installed irony via apt (sudo apt install elpa-irony) but Emacs doesn't seem to be able to find it, since I keep getting the message "Irony server isn't installed" whenever I open a C++ file. This kept happening even after a system reboot.

What am I missing here?

Thanks in advance!

When coding something like std::, it will popup the candidates. But everytime it shows this error:

error in process filter: Symbol's function definition is void: yas/current-snippet-table

But it also works except that it's too slow.

Irony install server yeilds this error every time i try an installation. Clang requirements are all installed. Can i be helped about what I'm missing here.

OSX now has a default installation of libclang under /Library/Developer/CommandLineTools/usr/lib and it will be really useful if there were precompiled binaries available from your repo that linked to this version of libclang. Currently, one has to install the humongous llvm package from homebrew just to get the header files to build it locally. In fact, a statically linked irony-mode that had no explicit dependency on libclang would be even better.

I was trying to run: cmake -G "MSYS Makefiles" .. To get the irony server, but it doesn't even get past msys2 gcc compiler validation... Am I missing something here? I am only using msys2 tools

I have the following in my .emacs.d/init.el file, I would expect it will enable the Irony mode when I open my C++ file, but it's not. As a workaround for now, I have to explicitly type "M-x irony-mode" to enable it.

; == irony-mode == (use-package irony :ensure t :defer t :init (add-hook 'c++-mode-hook 'irony-mode) (add-hook 'c-mode-hook 'irony-mode) (add-hook 'objc-mode-hook 'irony-mode) :config ;; replace the completion-at-point' andcomplete-symbol' bindings in ;; irony-mode's buffers by irony-mode's function (defun my-irony-mode-hook () (define-key irony-mode-map [remap completion-at-point] 'irony-completion-at-point-async) (define-key irony-mode-map [remap complete-symbol] 'irony-completion-at-point-async)) (add-hook 'irony-mode-hook 'my-irony-mode-hook) (add-hook 'irony-mode-hook 'irony-cdb-autosetup-compile-options) ;; (add-hook 'irony-mode-hook 'irony-eldoc) )

I also try to add these as suggested--> (add-hook 'c++-mode-hook 'irony-mode) (add-hook 'c-mode-hook 'irony-mode) (add-hook 'objc-mode-hook 'irony-mode) (add-hook 'irony-mode-hook 'irony-cdb-autosetup-compile-options)

but it's not helping though. Any help?

Searched for the following files but none are present on my system:

The definition of struct sigaction is

struct sigaction
  {
    /* Signal handler.  */
#ifdef __USE_POSIX199309
    union
      {
	/* Used if SA_SIGINFO is not set.  */
	__sighandler_t sa_handler;
	/* Used if SA_SIGINFO is set.  */
	void (*sa_sigaction) (int, siginfo_t *, void *);
      }
    __sigaction_handler;
# define sa_handler	__sigaction_handler.sa_handler
# define sa_sigaction	__sigaction_handler.sa_sigaction
#else
    __sighandler_t sa_handler;
#endif

    /* Additional set of signals to be blocked.  */
    __sigset_t sa_mask;

    /* Special flags.  */
    int sa_flags;

    /* Restore handler.  */
    void (*sa_restorer) (void);
  };

Without special requirement or using obsolescent compiler, the compiler usually chooses the #else so that sa_handler is one of members.

But irony doesn't show any candidates for sa_handler, my irony gives

There are duplicated items for the same candidate. That's because I'm using both irony and rtags. Both of them don't show sa_handler. But since they use clang as backend. I suspect it is a problem of clang, isn't it? There is another possible reason that I can come up with, that is there may be an option about compiler definition which should be given to irony but omitted.

Can anyone help? Thank ahead.
