Hi Marco!

Could you please provide example of erroneously parsed version string?
Also, were you using drivers from Ubuntu repos, or the ones directly from Nvidia website?

Hi Andrey,

I am using Ubuntu 14.04.5 and the NVIDIA drivers from the official CUDA PPA (so through apt-get).

Here is the version string:

NVRM version: NVIDIA UNIX x86_64 Kernel Module  361.93.02  Wed Sep 21 16:32:29 PDT 2016
GCC version:  gcc version 4.8.4 (Ubuntu 4.8.4-2ubuntu1~14.04.3)

This is the output without the proposed fix:

g++ -I/usr/local/cuda/include -L/usr/local/cuda/lib64/ -L/usr/lib/nvidia-NVRM version: NVIDIA UNIX x86_64 Kernel Module  361.93.02  Wed Sep 21 16:32:29 PDT 2016/ -L/usr/lib/nvidia-NVRM version: NVIDIA UNIX x86_64 Kernel Module  361.93.02  Wed Sep 21 16:32:29 PDT 2016/ cuda-smi.cpp -lcudart_static -lpthread -ldl -lnvidia-ml -lrt -o cuda-smi

Ah, okay, I see the problem. It's really a shame Nvidia is so inconsistent with their version numbering.

Please check if your problem is fixed in current master branch (87d9196).
I'd rather prefer to parse driver response with regex: it's not perfect, but relying on specific token position seems a bit more fragile to me.
