Thanks Xephan, will try - it is just a toy for me.
P.S. have mentioned Ufasoft in my #3 post here.
Topic: OpenCL in Gminer for CPU (Read 2914 times)
As I wrote above, Ufasoft CPU miner used to work quite well (about 8 Mhash/sec for 2 threads) with the deepbit pool, but it recently stopped working (while I have changed nothing). This is a known, acknowledged issue. The error code: 80190191. So, I am now experimenting with other CPU miners, not many of them left.
Missed out where you mentioned that. Good luck finding one that works well, sorry couldn't be of more help here

Looks like a confirmed case that it doesn't work without a discrete GPU.
I just tried it on my laptop with the Intel openCL installed, so while I don't get an openCL or openGL error, it was unable to get a device number.
Somebody asked about this in the cgminer thread as well but got no resolution so I'd suggest maybe you want to try using ufasoft's instead?

To avoid more confusion:
Again, my system is i5 2500K with GPU integrated with CPU, not running OpenGL. No separate video card is present, hence - only a CPU mining is possible.
So, why should I install an OpenGL if I can't use it in the first place?
I would have expected the following logic by cgminer: if no OpenGL is found - enable CPU mining only. If it is found - follow the input script parameters to enable either GPU or CPU mining.
No rocket science here.

OK, here is what I get when I try running my bat file that opens the CGminer exe, and links it to my pool:
System error: The program can't start because OpenGl.dll is missing from your computer
Indeed, it is better to call it an initiation problem, rather than install problem.

No confusion here, just a problem with the CGminer installation for CPU use only, as in my case of no separate GPU card and no OpenGL. It seems that the present installation is mainly for GPU mining with the CPU mining just on option, provided CGminer found the OpenGL first, to enable it to install.
I know that OpenGL could be installed separately, but at this moment, a much simpler solution of disabling the need of detecting the OpenGL at CGminer installation for CPU mining only, looks much more elegant.

More confusion, I just downloaded CGMiner to take a look... it doesn't need to be installed from what I could see. Just extract, then run in command line. So I'm not sure why you're seeing an error message.
Have tried to install CGminer to try it for CPU mining only. My system (i5 2500k, integrated GPU, Win7 - 64) doesn't support OpenGL. Installation demands OpenGL, although CPU mining does not use it.
Any idea about avoiding this problem?
Thanks

I'm confused as your title says it needs OpenCL but here you says it needs OpenGL.
Either way, Intel provides openGL drivers for the GPU so theoretically it should work. And they also have an openCL SDK available, although I doubt it would be any good from my own experience of getting barely 1/6 the normal ufasoft mhash.
I know that GPU mining can be about 100 times faster than CPU, but my system, i5 2500k, doesn't need a separate video card, and I am not yet into serious mining to add one. I am just experimenting.
Ufasoft CPU miner used to work quite well (about 8 Mhash/sec for 2 threads), but it recently stopped working with the deepbit pool.

Try another miner, there are several around =)
But, seriously, CPU mining is not worth it, you spend more money on
energy than you get BTC.
Peace.
