CUDA NSight c++11 (Ubuntu 14.04)

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:
