Description Piyush Bhoot 2016-03-23 14:26:12 UTC 
Description of problem:
Eclipse fails to resolve c++11 symbols like shared_ptr, 
it poses no problem during compilation though.

Version-Release number of selected component (if applicable):
devtoolset-4-eclipse-cdt-8.7.0-8.el7.x86_64

How reproducible:
Always

Steps to Reproduce:
1.Create new c++ plus project
  write word shared_ptr
2.Window -> Preferences -> C/C++ -> Build -> Settings -> Discovery -> CDT GCC Build-in Compiler Settings
in the text box entitled Command to get compiler specs append -std=c++11
3.Rebuild project, index 

Actual results:
Codepad shows Symbol `shared_ptr` could not be resolved.

Expected results:
Should show no such messages

Jeff, would you please investigate? This is major usecase we have to support.

> Jeff, would you please investigate? This is major usecase we have to support.

The code is working, but it needs some help to make it index properly.

From: http://stackoverflow.com/questions/9131763/eclipse-cdt-c11-c0x-support

First, one needs to go to:

Project->Properties->Preprocessor Include Paths->Providers and click on the CDT GCC Built-in Compiler Settings

Underneath, unselect "Use global provider shared between projects"

and in the Command string for finding built-ins, add: -std=c++0x

For the project, go to Project->Properties->C/C++ Build->Settings->Dialect and choose c++0x from the drop-down.

Rebuild your index if it already showing failure or build as usual.

I am using devtoolset-4-eclipse-cdt-8.8.1-9.2.el6-x86_64 and with the aforementioned changes, I am able to parse the following code fine:


#include <iostream>
#include <memory>
using namespace std;

int main(
  shared_ptr<int> sp(new int(5));
  cout << *sp;
  return 0;
}
