Eclipse CDT indexer does not know C++11 containers
Setting up **__GXX_EXPERIMENTAL_CXX0X__**
does not help in my case (Jul 2014, Eclipse Kepler 20130919, Ubuntu 12.04).
To fix C++11 syntax highlighting go to:
Project Properties --> C/C++ General --> Paths and Symbols --> Symbols --> GNU C++
and overwrite the symbol (i.e. add new symbol):
__cplusplus
with value
201103L
UPDATED: If you use newer version of Eclispe (as of 2016) and still experience the same problem, try value (as pointed by jose.diego):
201402L
Make sure that indexer is enabled in Project settings (C/C++ general --> Indexer)
Then reindex (Project --> C/C++ Index --> Rebuild)
if the problem still persist reindex once again. It should work now.
I solved this problem recently after some lucky googling.
Click on your project and right-click->Properties
Select "C/C++ General -> Processor Include Paths, Macros etc..."
Select the "Providers" tab
Deselect everything except "CDT User Setting Entries" and "CDT GCC Built-in Compiler Settings"
Click on "CDT GCC Built-in Compiler Settings"
Deselect "Use global provider shared between projects"
Edit the box at the bottom labeled "Command to get compiler specs"
Insert into the command -std=c++11 so it looks something like this:
${COMMAND} -std=c++11 -E -P -v -dD "${INPUTS}"
Click Apply and Okay.
That worked for me. You probably need to re-index the project.
As described in this forum post:
http://www.eclipse.org/forums/index.php/mv/msg/282618/
- right-click the project and go to "Properties" C/C++ General -> Paths and Symbols -> Symbols -> GNU C++.
- Click "Add..." and paste
__GXX_EXPERIMENTAL_CXX0X__
into "Name" and leave "Value" blank. Hit Apply, do whatever it asks you to do, then hit OK.
