$ git clone git://github.com/ckolivas/cgminer.git
Cloning into 'cgminer'...

...
$ cd cgminer

I did switch to my working build CGMiner build directory as the instructions said:
     Build cgminer.exe:
     Run the MinGW MSYS shell (Start icon => All Programs => MinGW => MinGW Shell).
     Change the working directory to your CGMiner project folder, \MinGW\msys\1.0\home\Aurum\cgminer-3.3.1

But, what is not stated is where to install other packages such as GTK-Win or Portable Git. It's implied to install them somewhere other than my CGMiner directory because it says "Extract" this and that to the, \MinGW\bin for example. I interpreted "extract" to be copy files rather than move files.

I'm not a UNIX programmer so all I can do is follow instructions and hope they work.

I tried running cgminer on windows 8 for the first time today and I didn't have any luck. It works fine for btc but I can't get scrypt to work. It stopped responding on windows. Is there a known issue with it?
What drivers/SDK? The newer ones don't work.

I'm using Windows 7 and all the latest ATI drivers, SPP and SDK work fine for 7970s. But, I cannot mine scrypt on 5970s to save my life. The documentation confuses me. SCRYPT-README.txt says, "The choice of driver version for your GPU is critical, as some are known to
break scrypt mining entirely while others give poor hashrates. As for the OpenCL SDK installed, for AMD it must be version 2.6 or later.
" But the GPU-README.txt says, "The best version for Radeon 5xxx and 6xxx is v2.5, while 7xxx cards need v2.6 or later, 2.7 seems the best." (2.8.1 works fine with my 7970s.)

So I installed the latest drivers from Catalyst 13.4, the latest SDK v5.0 and SPP v2.5. I compiled CGMiner 3.3.1 and 5970s cannot mine scrypt. I noticed during compiling that "--enable scrypt" is an unrecognized option. I also tried:
           CFLAGS="-O2 -msse2" --disable-option-checking ./configure --enable-scrypt
but that did not work either.

Any help would be greatly appreciated. TIA.

1) Do not use 13.4 with Scrypt. Actually even 13.1 won't work. Uninstall the drivers/SDK on your computer, and install 12.8 drivers (with included SDK).

2) You're building from source on Windows? Have you tried running the available binaries to see if that fixes it?

2. Yes of course I tried the canned CGMiner.exe! Why would anyone go to all this trouble unless they were desperate?!?!?!
I tried every combination of parameters, with and without auto-gpu. BTW, my 5970s run fine, but hot, with the BitMinter Client but gpu BTC mining is dead. I've tried the 5970s one-at-a-time, in pairs and quads. I have plenty of memory and have tried using 4 GB to 32 GB with matched sets of DDR3s. Also, they won't mine SHA-256 with CGMiner either.

1. I've previously tried 12.6 but I'll try again today with 12.8. I'm going to use Win7 to remove Catalyst 13.4 and all of its components. I'll follow with AMD's Cleaner program. Reboot into Safe Mode and run Driver Sweeper. Someone said that installing AMD-APP-SDK-v2.5-Windows-64.exe first is important.

Oops, correction: Should I install ADL_SDK_5.0 or a retro version? Yes, I'll use the Catalyst 12.8 included SDK as you said.

Then I'll install Catalyst 12.8 drivers & SDK only.

How about two scrypt MPs, one for microCap coins and another for midCap coins? My intuition says too many coins in one multiport cannot be optimal.

Hmm everytime the pool switches to NVC, my miners stop until the pool swaps to anything else. Anyone else seeing this?

I don't see any problems today on the US servers. I have a dedicated miner on NVC, a dedicated miner on PXC and the others are on MP.

Is CGMiner stopping when you switch to NVC?

I'm plagued with these stratum interrupted disconnects. Several of my miners will print a couple more lines and then just stop. Anything I can do to keep them running??? TIA
There's a bug in there somewhere which only recently got fixed in the git master code, so no official release has the fix. If you're building your own cgminer you can try it from git. Usually trying a different pool will make them go away as a workaround - it's a temporarily blocked network connection and pools with more resources don't suffer from it. There is also a stratum disconnect issue on windows from which cgminer never recovers, no idea if this one has been fixed with the latest changes or not.

Thanks, that's the only thing that correlates. Of my ten miners the ones on bigger LTC never seem to hang, but, the ones mining microcoins do.
I'm trying to install Git and pull the latest changes, but, git pull isn't working. I did the following (from Windows-Build readme.txt) and it seemed (me neophyte) to work fine:

Install Git into MinGW/MSYS:
http://msysgit.github.io/, click Downloads tab for the latest "Portable" git archive.
Copy the git*.exe files from the bin folder and put them into \MinGW\bin.
Copy the share\git-core folder to \MinGW\share.
To test if it is working, open a MinGW shell and type the following:
     git config --global core.autocrlf false (note: one time run only)
     git clone git://github.com/ckolivas/cgminer.git

$ git clone git://github.com/ckolivas/cgminer.git

Then I tried permutations of the following and nothing worked:
If you just want to update the source after you have already cloned, type:
     git pull
   "git pull" did not work for me. Try the following which does the same thing:
     git fetch && git merge FETCH_HEAD
Now you can get the latest source directly from github.

$ git pull
git: 'pull' is not a git command. See 'git --help'.

$ git pull origin master
git: 'pull' is not a git command. See 'git --help'.

$ git fetch && git merge FETCH_HEAD

For erupter/icarus problems, try current git (with a USB2 hub)

I do know that Raspbian fails badly.

What the details of the problem are is that since the Icarus devices never return a finished message, if they don't find a share, they never return anything.
This is of course expected, however, it would seem that certain linux kernels on certain hardware do not support a usb request timeout on USB1.1 devices (yes weird isn't it)
On these kernels, cgminer simply never gets a reply form the call to libusb (or more correctly, the call to libusb never returns)

I've found on my RPi when I switched from Raspbian to Arch the problem went away.

Have the issues I see in this thread seem to be focused around those Block Erupters. Seems they're more trouble than they're worth?
Worth? Smiley
Way too much and return way too little.
They currently mine only 0.00640097 BTC a day ... ouch!

They would be properly priced at $25, NOT $300. Just an expensive toy.
409  Alternate cryptocurrencies / Pools (Altcoins) / LTC Reject Rate on: July 20, 2013, 01:48:50 PM
I left a few miners on LTC for the last day and their rejection rate is 0.0986%
Keep up the good work.

I had a great day in LTC!!! I think I'm making double what I was making at WML.

The site just keeps getting better n' better. I like pool stats starting with the current MP coin. And the profit summary is nice too.

BTW, my hash rate values are right on.

Yes, cgminer 3.3.1 compiled with the latest AMD drivers etc.
I added "disable-no-pool" : true a few days ago but it still does it. Which reminds of a suggestion for the todo list.

I wish the Worker status was on its own succinct page. Workers down the left column, coins across the top, and hash rate in the table. No need for Active as that's redundant to hash rate. It'd be great if it auto-updated so I could check all my miners at a glance. You could put ads on the right side and turn the menu vertical on the left side. Cheers, Aurum
413  Alternate cryptocurrencies / Pools (Altcoins) / Re: Stratum+multipool.in => freezes on: July 19, 2013, 12:20:48 AM
One of my miners stops mining a few times a day after displaying "Stratum connection to pool 0 interrupted" it prints two more lines and stops. On my workstation I've occasionally seen that message but it'll recover and go back to mining. Some days a couple other miners freeze. Is there a configuration option or anything I can do to cure that??? TIA
414  Bitcoin / Mining software (miners) / Re: CGMINER for 5970 on: July 18, 2013, 11:47:04 PM
I'm trying to compile cgminer for 5970s and 5830s. I tried AMD ADL SDK v2.8.1 but it crashes. ReadMe recommends v2.4 or 2.5, but, AMD does not provide it in the archives any more. Does anyone know where I can download AMD ADL SDK v2.5??? TIA

That's a most excellent plan. I know it'll give me more incentive to stick around.

Would a solution be to rotate at least one cycle per day through each coin mined in the last 24 hours to preserve our shares???

Your older shares would expire. Here how it works: Every share you have found has a timestamp and would get rewarded for the next 24 hours for each found block during the 24 hour period.

Thanks for clarifying that. So, unless we find a block in less than 24 hours everyday then we will forfeit some shares. Clearly we don't have the critical mass to mine LTC in MultiPort. Compare that to WeMineLTC where they've found over 50 blocks today, 6,000 versus 500 MH/s.

So where would I get paid more if I left a miner dedicated to LTC 24x7???

If you want to mine LTC dedicated you will certainly get more consistent payouts at a dedicated LTC pool that has a higher hashrate than Multipool.

That's not to say you'd get paid more.  Our pool could have a lucky day and our miners could make more than the give-me-ltc miners.  We also have the feature of switching to more profitable currencies automatically.

It feels like it would be wise to leave a dedicated miner on 3334 and the rest in MP.

While I certainly won't complain about having more dedicated hashrate on the LTC port, I don't think that's the most profitable thing to do Smiley
What is the most profitable thing to do??? Keep all miners in 7777???

On average (given current hash rate of multipool of around 450MHs) around 12 LTC blocks will be found each day (assuming dedicated LTC mining), so each found share would be rewarded around 12 times. So, multipool has critical mass to mine LTC.
I agree for a dedicated LTC miner on MultiPool. I make more in MultiPort 7777. But, if 7777 does not spend enough time on LTC every day then I'm forfeiting shares.
