Miner not working on Ubuntu 16.04 LTS Linux

[nateGeorge]

I think I found out why I was getting a bunch of HTTP error 404 when trying to run sia-gpu-miner; the port seemed wrong. I found from gateway in the sia-gui terminal that the port was 9981. So I tried running the miner with `./sia-gpu-miner -P 9981, but it spits back these errors:

./sia-gpu-miner: /usr/local/cuda/lib64/libOpenCL.so.1: no version information available (required by ./sia-gpu-miner)
Port set to 9981
Initializing...

Failed to get header from localhost9981/miner/header, curl_easy_perform() failed: Couldn't resolve host name
Are you sure that siad is running?
HTTP error 0

I have the sia-gui running which I thought should work instead of siad?
