Hello,

Is it possible yet to have a package in ROS compiled with c++ 11 support? Or does ROS need to be compiled from source with c++ 11? If so, is this possible?

Thanks in advance.

I might be wrong but would like to give it a try.

Given that ROS supports only C++03 up to Hydro so far and as far as I haven't seen discussion about C++0x support, I think your question falls into general C++ discussion. And because of possible API incompatibility, mixing compiled C++03 and C++0x may or may not work.


UPDATE) This newer thread might answer more to your interest.

I had seen that post too, but since it was from 2011 I had hoped it would be possible by now. I added the c++0x flag and the c++11 flag but in both cases I get an error from some ros messages. Guessing it is not possible yet, but it has been out for a while now so making that step seems logical.

I would suggest then to start discussion in [ros-users](https://code.ros.org/mailman/listinfo/ros-users) (I'm not sure which component is the right place).

Thank you for the update, I am indeed using OSX. Too bad c++11 support doesn't work proper on OSX then.

Nowadays it is possible.

Just add this to your CMakeLists.txt file

if(CMAKE_COMPILER_IS_GNUCXX) add_definitions(-std=gnu++0x) endif()

Be careful with the boost::shared_ptr pointers that are intensively used in ROS and but they are not compatible with std::shared_ptr
