I run poclbm on my system but for some reason both deepbit and slush don't "see" the work being performed. My system reports about 200 megabashes per second being done. I tried mining with my cpu using the same settings, and then both deepbit and slush recognized that work was being performed.

These are the errors I am getting out of the respective mining hardware (every minute or so):

poclbm error: pit.deepbit.net:8332 22/02/2013 21:50:59, Verification failed, check hardware! (0:0:Cypress, d47b7ba0)

cgminer error: [2013-02-22 22:18:51] GPU0: invalid nonce - HW error

I am using Ubuntu 12.10 (Quantal Quetzal) with the 12.10 version poclbm with an ATI 5800 series video card. The video drivers are installed and work as far as I can tell. When I run a "aticonfig --odgc --adapter=all", the gpu does seem to be utilized with poclbm (around 70% utilization or so).

I found the solution through an irc channel (Freenode on channcel #cgminer). Basically, at least on the version of Ubuntu that I have (12.10), the 2.8 version of the SDK does NOT work properly with cgminer or poclbm. I was instructed to download the 2.4 version of the SDK. Here: http://developer.amd.com/Downloads/AMD-APP-SDK-v2.4-lnx32.tgz http://developer.amd.com/Downloads/AMD-APP-SDK-v2.4-lnx64.tgz

Some distributions require the "2.7" version so I'll put the links here: http://developer.amd.com/Downloads/AMD-APP-SDK-v2.7-lnx32.tgz http://developer.amd.com/Downloads/AMD-APP-SDK-v2.7-lnx64.tgz

I compiled it. There is no "make install" for this Makefile, apparently, so you have to manually copy the files to your lib directory:

for 32 bit: $ cp -pv lib/x86/* /usr/lib/

for 64 bit: $ cp -pv lib/x86_64/* /usr/lib/

Also copy the include files: $ rsync -avl include/CL/ /usr/include/CL/

With the libraries installed in the appropriate directories, I recompiled cgminer and then it worked. I also tried it with poclbm and it worked with that too.
