Platformio-atom-ide: Clang linter keeps warning about c++11-only features

[frnhr]

I'm new to PlatformIO (and love it), so please forgive me if I'm being n00b here.

I'm using PlatformIO for Arduino, with mostly default settings. There are some C++11 - only features in the code. Arduino compiles with -std=gnu++11 flag by default, so it compiles successfully.

But the linter still warns about features only available with this flag:

I have tried to add -std=gnu++11 flag to .clang_complete file manually, no results.

Is there a way to get rid of these warnings, without giving up all other warnings as well (as would be the case with "gccSuppressWarnings": true)?

Could you provide the code/platformio.ini to reproduce this issue? Thanks.

A clean installation of PlatformIO, on a clean Os X (virtual machine):

• start a new project (I'm using Arduino Mega 2560)
• create a new header file src/something.h
• paste this code in:

class A
{
public:
  int a_list[5];
  A() :
    a_list{1, 2, 3, 4, 5}  // This line
  {};
};

• save

GCC warning extended initializer lists only available with -std=c++11 or -std=gnu++11 [enabled by default] at line 6 col 6

This warning appears in files with .h or .hpp extension, but not in those with .cpp extension.

1. Try to use .hpp instead .h
2. Menu: Rebuild Index C/C++
3. Close Atom. Open it.

Does it work?

P.S: I've just checked it under Mac and it works very well.

[ivankravets]

Please reopen if it doesn't work for you.

Indeed it works! Thanks for the suggestion.

A side note: I'm striving to keep full compatibility with Arduino IDE when using PlatformIO / Atom, and apparently Arduino IDE knows about .hpp files too, so that's nice...
