Irony seems unable to cope with system headers

adamemerson commented 5 years ago

I get system headers flagged with errors. The below is from <memory>

Have you seen anything like this or have any idea what to do with it? Compiling things with Clang works fine.

I'm using Emacs 26.1 Clang 7.0.0 libstdc++ 8.2.1 Irony 20181030.834

On Fedora 29

Thank you

Same issue here. I guess can be related to clang 7.0. With Fedora 28 and clang 6, all was fine.

`In "shDefs.h": 'float.h' file not found

In "../../../../../../usr/include/stdlib.h": unknown type name 'size_t'

In "../../../../../../usr/include/stdlib.h": unknown type name 'int32_t'

In "../../../../../../usr/include/stdlib.h": unknown type name 'size_t'

In "../../../../../../usr/include/stdlib.h": 'stddef.h' file not found`

Hey there, does anyone have been able to fix this issue ? I get the same error after upgrading to clang 7.0 on macos as well, and cannot figure out what to do to fix it for now.

Have you ever tried to recompile the irony-server? If not, to do so, type M-x irony-install-server RET. In my case, it resolved after upgrading to clang 7.0. Regards.

jeremyletang commented 5 years ago

Yea I tried earlier but it does not fix the issue.

Hey there, if anyone get the same issue on macos, I finally get this to work again recently. I had to specifiy the path to the C++ std include but also to the C include. Here is the configuration I added to my init.el if it can help anyone:

(setq irony-additional-clang-options
      (append '("-I" "/usr/local/Cellar/llvm/7.0.0/include/c++/v1") irony-additional-clang-options))
(setq irony-additional-clang-options
      (append '("-I" "/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include") irony-additional-clang-options))
(setq irony-additional-clang-options
      (append '("-std=c++17") irony-additional-clang-options))
