I updated cuda7.5 to cuda8.0 and then everything goes fine:-). Thanks for lighting up this.

Have you checked your gcc version?

You should use a gcc that supports C++11 feature, say, at least >=4.8
Let me know if updating gcc still couldn't solve the problem.

@HMLONG Have you been able to solve the problem?

@yzhwang The Segmentation fault error occured when I used gcc4.8 and g++4.8. I updated compiler to gcc5 and g++5 and then the new error occured:
$make
mkdir -p bin

The problem occured at morderngpu/transform.hxx line 21:
launch_box_cta_k
<launch_box,
func_t> <<<grid_dim,``cta.nt, 0, context.stream()>>>(f, num_ctas,
args...);
When I comment this line, the segment fault error gone. I can make successfully but the program can't execute correctlly.

Yeah... that's a very important line of code :-). So actually I've never tried compiling this in CUDA 7.5 (I've been working on CUDA 8 all the way). Here is my setting:
CUDA 8
gcc/g++ 4.8.5
driver: 367.48
Sorry about this, since this library is only an experimental one, I haven't thoroughly tested it under different hw+sw.
It would also be benefitial if you could try building moderngpu 2.0 first and I assume once you get that done, it won't be difficult to get gunrock mini to build, since other than using moderngpu 2.0, it doesn't have any other dependency. Good luck!
