Is ROS compiled using c++ 11 with catkin? I suspect not since I am getting an error trying to use {} initializer for a vector, i.e. c++98...must be initialized...
For at least my builds where in the catkin files would I add the '-std=c++11' option?
I am using Eclipse but I think this is controlled via the cmake files, not a project property.
All the current distributions of ROS are compiled using C++03.
You can compile your own packages using c++11 by adding the following line to the CMakeLists.txt of your project:
add_compile_options(-std=c++11)
Note that it is recomended to have checks for c++11 features at configure time and provide equivalent functionality with extra compiler features. This is only required if you are planning to release the ROS packages that you develop. If you are only planning to use your packages yourself then you can just c++11 functionality. You can read more about ROS and C++11 here: link text
You have to add
set(CMAKE_CXX_FLAGS "-std=c++11 ${CMAKE_CXX_FLAGS}")
to the CMakeLists.txt of your package.
Also consult this: https://gcc.gnu.org/wiki/Cxx11AbiComp... Not sure if ROS is compiled to be ABI compatible between C++ versions.

I poked around and found that adding the "-std-c++11" in the file flags.make worked. But I suspect it will be overwritten the next time I add a file to the CMakeLists.txt. Just wanted to mention this with the warning. The file was overwritten with the changes to the C*.txt file.
Both answers provided worked. I flagged the one by Julius as 'correct' since it was more succinct. I added the line to just below the ## Build ## box, just fyi. Appreciated also the link to ROS/C++11 points.
