CUDA NSight c++11 (Ubuntu 14.04)

Question

I read the CUDA Programming Guide and have looked at a number of links here including the following: Eclipse/Nsight (7.0) and C++11 support

But can't get things to work. I'm using CUDA 7.O and the doc (CUDA Programming Guide, p.187) says that -std=cc++11 is supported for gcc >=4.7 & clang. Running using using gcc 4.8.2 (OS: Ubuntu 14.04) and despite going to Project -> Properties -> NVCC Compiler ->Build Settings -> Preprocessor options (-Xcompiler) and adding -std=c++11 I'm getting all kinds of errors. See patial output from console below (at very bottom see "nullptr" is undefined). I've spent +5hrs looking at and trying a number of suggested solutions and at links the nvidia dev forum and on stackoverflow and have yet to find a resolution. Where do I set the flag properly?

Partial console output:

Answer 1

This is wrong:

-Xcompiler -std=c++11

Just use this, as a switch to nvcc:

-std=c++11

nvcc will handle the necessary upstream switches needed for gcc/g++.

You can do this "automagically" in the CUDA 7 version of nsight eclipse edition, by going through the following sequence:

Project...Properties...Build (expand sub-menu)...Settings...Tool Settings...NVCC Compiler (expand sub-menu)...Code Generation

and selecting the "Enable C++11 Support" checkbox. (There are other ways, as well, such as just going to the "NVCC Compiler" page and adding the switch manually on "All options")
