C++ 11 headers issue [message #1034561]

Hello,

I'm using MinGW and one of headers is <initializer_list>
it 's compiled successfully, but Eclipse parser can't parse this template correctly,
it doesn't highlight the include itself, then eclipse "sees" the header but shows the error: "Symbol 'initializer_list' could not be resolved"

I've opened initializer_list header and see that CDT highlights block (most of this header) as __GXX_EXPERIMENTAL_CXX0X__ is not defined:
"
...
#ifndef __GXX_EXPERIMENTAL_CXX0X__
# include <bits/c++0x_warning.h>
#else // C++0x
...
"
I believed that compiler option -std=c++11 defines this, is not it? because compiler works without errors.
But CDT parser have started to work properly only when I added __GXX_EXPERIMENTAL_CXX0X__ into C++General/Paths and Symbols/Symbols
why?

Same problem here.
I use Eclipse CDT Neon, the toolchain is Linux GCC (version 5.4) with the "-std=c++11" flag.
The Eclipse parser sees an error (Symbol 'initializer_list' could not be resolved) whereas the code compiles and works perfectly fine.

I tried reproducing the problem. When I changed the language standard:

index.php/fa/27857/0/

I was prompted to rebuild the index:

index.php/fa/27858/0/

After that the indexer behaved properly.

So there are a couple of things going on, perhaps sometime in the past "Remeber my decision" saved a No so you weren't prompted, or perhaps CDT didn't notice the setting change affected the index.

Either way, you should be able to resolve it by right-clicking on the project and choosing Index -> Rebuild.

PS If you aren't getting the prompt when changing the setting, you can reset the Remember my decisions aka do not show again prompts in C/C++ Preference Page:
