Not sure if it's because I'm on Ubuntu 13.04 or what, but I'm getting this error again when I upgrade to cgminer 3.1:

Code:
./cgminer: error while loading shared libraries: libjansson.so.4: cannot open shared object file: No such file or directory

3.0 is working great; more stable (hashrate wise) than ever, actually. Probably has something to do with the sexy new version of Unity. Tongue

hi,

can you point me to where 3.0 installation guide is? Cheesy

I know this may have been asked and answered already, but I couldn't find anything and my post got lost in the newbie forum. Please don't hate me if I did miss something or completely misunderstood the FAQ's.

I'm running a GTX 670; yeah I know NVIDIA, but I make a super small profit and I got it for gaming. I see this as more of a hobby or something like folding@home, but can make some money off of. OK, getting back on topic, no matter what driver I use (tried ~4) I can't get the CPU usage in Linux to drop from 100%. I wanted to know what if there was a particular driver that works well or something. Also, I don't quite understand the whole kernel thing for cgminer, so my next question is, is there a kernel that is better suited to a NVIDIA card like mine? I noticed there are suggestions for ATI, so I'm just throwing it out there.

Are you trying to use OpenCL or Cuda?

CGMiner requires OpenCL

I'm just using the defaults in cgminer and I downloaded the dependencies for it as well such as opencl-nvidia. I've already had it running fine in Windows for a while, but I would prefer to run it under Linux as I use Linux for my main stuff and Windows for gaming.

OK, are you getting around 112Mhs in Windoze?

If your building  a dedicated mining machine I would get any AMD GPU as it would give you a higher hash rate and use less electricity.  Otherwise I would just continue running in Windoze since it is working.

Good Luck,
Sam

I appreciate the feedback, but I would like to know what the issue is under Linux and why it runs fine under Windows. I'm not really looking to build a machine to mine, I'm just trying to use what I already have when the computer isn't being used. I already know what kind of hash rate I should be getting etc. My issue is with cgminer and Linux.

OpenCL implementation vary from driver to driver. When doing compute work, they can choose to "busy wait" on the CPU or sleep while waiting for the GPU to return its answers. Direct CUDA has a way to tell the device which mode to use, but OpenCL does not have any such command, thus it is entirely up to the driver/GPU/OS combination - and some GPUs you may never find a driver that doesn't busy wait. There is precious little experience with Nvidia drivers since their profitability is 1:4 compared to the electrical costs. You can try one of the new dedicated CUDA miners out there instead (although they will be primitive and buggy code since cgminer has been in heavy development for 2 years by comparison).

Yeah, I figured that no one really works on NVIDIA because it's not worth it. I don't really know of any CUDA based miners on Linux that aren't like 2 years old, lol. I still would've liked to use this under Linux... guess I'll just have to chalk it up to NIVIDA still hating on the Linux crowd; as Linus put it, FUCK YOU, NVIDIA! Though, if you would be willing to work on adding some CUDA support, I could throw a few "satoshi" your way ;P

Direct CUDA support is a lot of work and no one could afford to pay me enough to do it  Lips sealed

Oddly, I see it the other way around: Linus hating on nVidia coz they wont do exactly what he wants.
nVidia supplies VERY good linux drivers for everyone to use.
Why must nVidia supply drivers, the way Linus says they should? Especially when they already do supply them ...
Yes nouveau sux ...

You do have a point. I just don't understand why making the drivers open source is such a taboo. Is a driver really going to let other companies steal their designs or something?

Hi, I am running cgminer 3.1.0 with 13.4 ATI drivers.
cgminer starts up, I wait a little, and crash. Here is the log file.
http://pastebin.com/cMLkmLrg

My cards are as follows : Gigabyte6950,Sapphire5870,Ref5870,Ref5970
I read about "good drivers", I just installed drivers 12.8, and the drivers won't seem to load properly on my machine, I get "loadMM.exe failed to start" and cgminer still crashes on startup.

Before I tried this, I was running cgminer 2.11.4 as well as AMD drivers 13.1. I had the problem where if I rebooted sometimes cgminer would fail to start (but not crash). I had to boot in safe mode, uninstall all the ati cards, reboot, have Windows detect them all again, reboot, and it would work. But that's really an unstable situation to manage remotely Sad

[edit] I have re-installed a fresh copy of Win7-x64, installed 12.8 drivers and ran cgminer 3.1.0, seems to be running fine for now.

13.x drivers seem to be buggy for us with the older 5xxx cards unfortunately...

Just upgraded to ubuntu 13.04 - cgminer didn't like it:

cgminer/cgminer: error while loading shared libraries: libudev.so.0: cannot open shared object file: No such file or directory

Current cgminer is built on 12.10 equivalent ...

cgminer on 12.10 gave me lots of hardware errors at any decent level of intensity with Litecoin mining. Couldn't get it to work at all with 13.1 or 13.3 (hangs/crashes at the version screen, runs with -T but doesn't produce useful work). I am now on 12.08 which seemed to be mining OK for about two hours with both BTC and LTC at the same time but then we had a power blip and things aren't working right anymore (not sure if hardware or software, had to bail and go to bed). Max intensity I can mine LTC with on the 7950 is 18 at about 520kh/s.

This post is more informational than looking for a solution to any problems (though any advice always appreciated).

Details:
OS: Win7 64bit
Video: Sapphire 7950 (slot 0), HID 5970 (slot 1)
CPU: AMD quad something.

That's what I was doing but my 5970 is misbehaving as it shows up but does 0/0 on one or both GPUs and then reports sick, whatever. But it has randomly in the past too. I'm wondering if my 12V lines are not keeping up. It's a reflowed unit so possibly it is just not doing so well.

TC, intensity, lookup-gap and -g would be nice to know Smiley (found that setting TC to low will give you hardware errors on this new version, minimum is 8192)
