Blender: CUDA kernel compilation failed
I tried the solutions presented in this other question without any succes: CUDA kernel compilation failed
Ie: I've tried running blender from terminal using sudo blender, installing g++5, changing kernel.cu. But nothing so far has worked
I'm using Ubuntu 16.04.5 LTS 64-bit
My graphic card is GeForce GT 740M/PCIe/SSE2 and I'm running Blender 2.76
$ nvcc --version

This is what the terminal shows when trying to compile:

On my machine, using Ubuntu 16.04 and Cuda 9.2, it looks like tweaking the util_half.h file solves this particular issue, though it seems to take forever for the rest of the process.
You want to add the following include:
#include "cuda_fp16.h"
And comment out the line:
typedef unsigned short half;
The file is located at:
/usr/share/blender/scripts/addons/cycles/kernel/util_half.h
The correct way is to simply download a newer version of blender, which works with Cuda 9 out of the box.
