what is the right syntax command for ethminer?

Hi I have been referencing many sources but most seem to be for window's commands

I am using ubuntu 16.04 LTS

Here's what I run in my shellscript:

#!/bin/bash
export GPU_FORCE_64BIT_PTR=0
export GPU_MAX_HEAP_SIZE=100
export GPU_USE_SYNC_OBJECTS=1
export GPU_MAX_ALLOC_PERCENT=100
export GPU_SINGLE_ALLOC_PERCENT=100
ethminer -F http://eth-asia1.nanopool:9999/bfe991e7f8070e3da9c8c2f8f1074a8e06ab7126/lgh1 -G --cl-global-work 16834 --cl-local-work 256 --farm-recheck 200

HOWEVER, I am seeing this error everywhere:

ethminer: /usr/local/cuda-8.0/lib64/libOpenCL.so.1: no version information available (required by /usr/lib/libethash-cl.so)
[OPENCL]:Found suitable OpenCL device [GeForce GTX 1080] with 8508145664 bytes of GPU memory

I could do:

$ ethminer -G -M

Tell me if I am doing my command syntax right for pooling?
