Here's what I'M seeing:

 [2013-07-10 22:06:16] Started cgminer 3.1.1
 [2013-07-10 22:06:16] clDevicesNum returned error=2C no GPUs usable
 [2013-07-10 22:06:16] No devices detected!
 [2013-07-10 22:06:16] Waiting for USB hotplug devices or press q to quit
 [2013-07-10 22:06:16] Need to specify at least one pool server.

=============================================================== From: Garrett Gaston ------------------------------------------------------ To you bitcoin guys. when I run./cgminer=2C I place my credentials in and t= hen the program shuts down back to the command prompt. I did echo $? and go= t a return status of 1. Do any of you have any ideas=2C or can you at least= point me to where the cgminer logs are kept? Thanks. Oh=2C it was working = fine several days ago=2C don't know hat changed. =

=============================================================== From: Sudo Bash ------------------------------------------------------ [2013-07-10 22:06:16] clDevicesNum returned error, no GPUs usable That error won't stop you from mining, but it means you either don't have a capable GPU / Need to update or Install your drivers for your GPU('S), or you didn't compile support for CUDA/OpenCL into cgminer. This effectively cuts your mining power by mining only with your CPU cores which is not very efficient and you will hardly earn anything... [2013-07-10 22:06:16] Need to specify at least one pool server. This is the error stopping you from running cgminer, you need to tell cgminer whether or not you're mining solo or in a pool via a config file you must create and specify. A pool might be your only chance of seeing ANY return at all if you are mining via CPU's only. If you have a super powerful rig with multiple video cards, it might be worth mining solo, but you might be burning electricity. You can always look into mining Feathercoins or any of the other cryptocurrencies that have since popped up and are becoming quite profitable because the algorithm they are using are resistant to ASIC mining and thus have given the profitability back to GPU miners. Check out some resources and research. Look a profitability calculator for feathercoins: http://benhohner.com/feathercoin/ Blogs about cryptocurrencies: http://www.coindesk.com/feathercoin-founder-peter-bushnell-talks-about-cryptocurrency-challenges/ Don't forget, everything is vulnerable: http://www.coindesk.com/feathercoin-hit-by-massive-attack/

=============================================================== From: Sudo Bash ------------------------------------------------------ Hey I was thinking about it and re-read your post and I think the GPU error could be your issue. I believe in cgminer you have to specify a flag to enable cpu mining, and if you didn't do that and something happens to the drivers or OpenCL libraries then cgminer won't run at all. Remove and re-install the latest driver module for your graphics card, and do the same for the latest SDK that installs OpenCL, reboot and see if it works then. Re-post any information that is different and I can probably help tomorrow afternoon.

=============================================================== From: Matt Keys ------------------------------------------------------ If you've recently upgraded the kernel you've likely overwritten the GPU driver and will need to reinstall it. Regards, Matt

=============================================================== From: Garrett Gaston ------------------------------------------------------ When you say "SDK that installs OpenCL"=2C are you talking about a driver f= or my video card? Also=2C I didn't compile cgminer=2C all I did was unpack = the tarball and ran ./cgminer. As far as my graphics card goes it's an ATI = Radeon 3000. ATI does not support Mint Linux but this is the drive that I u= se for it anyway=2C amd-driver-installer-catalyst-13.1-legacy-linux-x86.x86

=============================================================== From: Matt Keys ------------------------------------------------------ I have no clue where that first sentence came from lol. You must have downloaded pre-compiled binaries of cgminer. I like to use git to snag the latest version : $ git clone https://github.com/ckolivas/cgminer.git $ cd cgminer $ ./autogen.sh --enable-bflsc $ make $ sudo make install BTW - You guys will need the latest version for stable mining on the new bfl equipment. v3.2.1 and my bfl jalas didn't jive. About every 3rd day of mining it'd just scroll shitloads of rejects and I'd have to bounce cgminer. Since uprading to the latest (v3.3.1) it's been stable so far. ...and I'm still waiting for the single sc to come in. cpu mining was removed completely from cgminer. You'll have to dig through and find an older version of it to do that anymore. For gpu mining the GPU-README file is well documented. The compile flags and package names you'd need to compile cgminer itself are in the README file. You've got the right gpu driver version there but the app-sdk is a separate install from that. wget won't work but you can get it here after clicking agree : http://developer.amd.com/amd-license-agreement/?f=AMD-APP-SDK-v2.8.1.0-lnx64.tgz

=============================================================== From: Garrett Gaston ------------------------------------------------------ I just followed your steps and I also installed APP SDK. Which I had an NVI= DIA card. Anyway=2C this is what I got after running cgminer: -> [2013-07-16 17:14:58] Started cgminer 3.3.1Segmentation fault (core dum= ped) Also=2C when I try to run GUI Miner I get an error saying that no OpenCL dr= ivers were found. I downloaded APP SDK and the Catalyst drivers from ATI.

=============================================================== From: Matt Keys ------------------------------------------------------ Garrett, In your previous email you said the card was an ATI "As far as my graphics card goes it's an ATI Radeon 3000". nVidia cards are going to be a bit different than the ATI installation. Did you read over the GPU-README file? If you have some spare time soon let's get together on a remote support session and I'll walk you through it. Email me off list with contact info and your availability. Matt
