The syntax marker problem is downstream from what it took to get CDT to compile code with C++11 features. Initially CDT wouldn't build C++11 code and threw lots of compiler error messages in the Console view and didn't support content help for C++11 features in the editor. I suspect the syntax marker problem was always there all along but didn't notice it. At any rate, after determining that there was nothing wrong with the GCC tools I believe that I solved the compiler side of the problem at the project level (not workspace wide) by setting Eclipse/CDT project preferences GCC C++ Compiler and GCC C Compiler Miscellaneous settings to include other flags -std=c++11 and -std=gnu11 respectively. At this point I get the error markers (syntax, not compiler) every time I save a .cpp with C++11 features (which impacts both the text editor and the Problems view). Deleting the syntax markers manually out of the Problems view removes the markers from the text editor. My attempts to enable C++11 code completion and code analysis has been both time consuming and frustrating e.g. have tried workarounds for older versions of Eclipse and/or CDT that do not work (e.g. discovery vs. compiler invocation arguments, re-indexing, etc.), have reviewed postings with recent dates that direct me to take actions not supported by the integrated IDE I am using (e.g. specifying project preferences that include 'C/C++ General' then 'Preprocessor Include Paths' then 'Providers' etc.), etc. etc.. Sad

Correct Eclipse and CDT terminology aside, I think I need a method to specify use of C++11 features to the code completion and code analysis functions. Long term I am looking for a workspace wide (not a project level) solution for C++11 development. Surprised

Status Update: Note: following has all the helpful links stripped out because I have fewer than 5 messages: Lots of effort since my last post but I still have syntax marker problems and missing editor content help (code completion and code analysis) for C++11 (primary problem) and it turned out that:
1. I cannot compile all C++11 features (new secondary problem but not a showstopper)
2. My existing ADT Eclipse bundle from late 2013 (marked Juno) did not support project properties, C/C++ General, Preprocessor Include Path, Providers Tab, deselection of all except CDT GCC Builtin Compiler Settings etc. etc. etc

Since my last post I have attempted to:
• re-install MinGW4.8.1 IAW <link removed by author>.
• Update to the latest MinGW v4.8.1-4
• Tune use of the MinGW toolchain from Eclipse IAW the useful posting at <link removed by author>.
• Swap out MinGW for MinGW-Build per the useful posting (downloaded from <link removed by author>) to address possible inability of the MinGW distribution to compile C++11 properly (for reportedly supported features). Note: to date swap has failed due to TBD download problems (currently working download issue with the sourceforge mingwbuilds project folks at <link removed by author>).

Confused

At this point I have given up working workspace wide (not project level) configuration of the toolchain. Currently only working what may positively impact the primary problem e.g. download MinGW-Build and use it instead of MinGW, download boost library, etc. Comments and clues welcomed.

I am having a very similar problem. Old projects recognize C++11. These were set with older version of Eclipse and CDT.
Now when I import code as new projects, I don't know how to make CDT recognize C++11 anymore. As the above post says, none of the Google results I can find help because the menus for the proposed solutions do not exist anymore. Could someone post an authoritative answer as to how to do it with Eclipse Luna and the latest CDT?

for the indexer

Project / Properties /
C/C++General
Preprocessor Include Paths, Macros etc.
the tap Providers

CDT GCC Build-in Compiler Settings
add -std=c++11 -
to the command to get compiler specs

It is a bit cumbersome to do that for each and every project...
Can't we set a version for the CDT, or at least for the current workspace?

Window - Preferences - C/C++ - Build - Settings
second tab Discovery

here you can set the defaults
if you set there your c++11 discovery it will be used as default
