OFFICIAL CGMINER mining software thread for linux/win/osx/mips/arm/r-pi 4.10.0

[-ck]

New release: 4.2.3, 3rd April 2014



- Solo miners can now add their own signature of up to 32 characters to the coinbase with the --btc-sig option.

Great! Thanks.

It appears that spaces aren't allowed.  Are there any other characters that aren't allowed, that you may know of?

Spaces are allowed, you just have to quote the signature.

Good info.  Thanks

The --btc-sig was missed in the readme altogether.

Yeah sorry I realised after I had already put together the release. Oh and you can use any characters you like provided it's all quoted.

Sounds like it is time for me to set up a solo miner. I'm totally about getting my name all over the internet.

Sounds like it is time for me to set up a solo miner. I'm totally about getting my name all over the internet.

I recommend any miner who has a full bitcoind running somewhere on their lan should have solo mining as their last backup anyway, in case every single pool you are mining on falls over for whatever reason. It's good security for you and the network.

Con,
I found two cosmetic bugs in cgminer-api

static void disablepool(struct io_data *io_data, __maybe_unused SOCKE
.........
   pool->enabled = POOL_DISABLED;
   enabled_pools--;


 

And same in enablepool

b]enabled_pools++;[/b]




Thanks

PS:What about my previous question about stale_work
      work->job_id = strdup(pool->gbt_workid);

and checking it's job_id

In general there is no code when gbt work becomes stale.

Thanks

[-ck]

Con,

I am looking at stale_work() code. I am wandering if work gets stale in solo and gbt also?

if (pool->gbt_workid)
      work->job_id = strdup(pool->gbt_workid);
Shall job_id be checked inside stale_work code. For stratum it is considered as stale if there is no share but for gbt and solo?
Thanks

There are enough checks to determine if work is stale with gbt solo/pool already.

work_block is enough to pick up if we're working on the same block. work_id is used only for pooled gbt mining (not solo) to tell the pool which gbt update it came from (and is optional at the pool end).

could anybody be so kind and give step by step instruction on how to get 4.2.2 working on linux (ubuntu)?

From reading the first post in this thread, you learn you have to do this:

Go here: http://ck.kolivas.org/apps/cgminer/

If you have 32-bit Ubuntu, download the file cgminer-4.2.2.tar.bz2.
If you have 64-bit Ubuntu, download the file cgminer-4.2.2-x86_64-built.tar.bz2

Either way, unzip the file you downloaded.  Then run the executable you just unzipped, follow the prompts to set up your first pool, plug in your devices, and poof, you're mining.  (I also suggest, after you configure your pool and other settings, that you save a config file using the in-program menus and prompts.)

For anything more specific than that, you'll have to ask a clearer question.

ok iĺl be more specific...

last time i had cgminer running it was 3.7 i think through the console/terminal so i dont know wich executionable you are talking about.. if you could be so kind and tell me i would apreciate it.
i need to get cgminer running now, as i have just received a package.

The following code snippet appears in cgminer.c from the latest (April 4, 2014) git clone.

Code:

   3073         } else {
   3074                 char *hexstr;
   3075
   3076                 endian_flip128(work->data, work->data);
   3077
   3078                 /* build hex string */
   3079                 hexstr = bin2hex(work->data, 118);
   3080                 s = strdup("{\"method\": \"getwork\", \"params\": [ \"");
   3081                 s = realloc_strcat(s, hexstr);
   3082                 s = realloc_strcat(s, "\" ], \"id\":1}");
   3083                 free(hexstr);
   3084         }

Question: in line 3079 why is the data length being passed to bin2hex()  set to 118? Should this not be 'sizeof(work->data)', that is to say, 256 bytes?

No because only those variables are actually the work payload which becomes the result. Other data in the work struct are private.

Either way, unzip the file you downloaded.  Then run the executable you just unzipped, follow the prompts to set up your first pool, plug in your devices, and poof, you're mining.  (I also suggest, after you configure your pool and other settings, that you save a config file using the in-program menus and prompts.)

ok iĺl be more specific...

last time i had cgminer running it was 3.7 i think through the console/terminal so i dont know wich executionable you are talking about.. if you could be so kind and tell me i would apreciate it.
i need to get cgminer running now, as i have just received a package.

I thought it was clear - "run the executable you just unzipped". The executable is cgminer - it's just zipped up for faster download. Once you unzip it, you just run it, like any other Linux program.  Either type in the name from the command line, or double click the file if you're using a GUI.  If you want to control how it runs, check the readme file and set the command line parameters the way you want them, or configure them in the program and write the config file using the built in function.

I'm sorry, but I'm honestly not sure how to be any clearer. If you don't know how to run a program in your preferred operating system, then you need to spend some time learning how to do that along with other basic tasks, like how to safely boot and shut down the PC, or how to log on and log off, or how to save your documents for later use.

Are those steps apply for the Raspberry pi as well. I was looking for a detailed Installation instruction like this a page before and ended up with backing up my previews version 1.8 or so. I am mining on 2GH/s with a Antminer U2 with a 14% error rate.

Yes  

The different is you don't need sudo while compile cgminer & add --enable-icarus

Code:

1. git clone https://github.com/ckolivas/cgminer.git
2. mv cgminer cgminer-4.2.3
3. cd cgminer-4.2.3
4. ./autogen.sh --enable-ants1 --enable-avalon --enable-bitfury --enable-icarus
5. make

OK thanks. That helped.
I had to install linux again next to the one i had already installed to get it working. I tried autogen and make yesterday, but there where some errors and when it returned errors today when i tried it your way i decided to install linux again.
At first it did'nt work when entering sudo ./cgminer, but that was because there was no asics enabled.
I have tried to enable bitmine A1 asics, but it could'nt.

All i need now is to get the technobit 130 ghs running...

Any pointers?

Hi, I have a question about the Cgminer API, and I hope this is the correct thread for these questions.

The Network Difficulty is reported by the Coin command, but if you have two pools with different coins, you don't know for which pool the Network Difficulty is reported. It looks like the Coin command reports the network difficulty for the pool/coin that had the last network difficulty change, but that isn't always the highest prioritized pool where you actually mine.

Isn't the Network Difficulty something that would be better to include in the Pool command, and specified for each pool?

Thanks for a great API and please let me know if I got all this wrong.

We don't care about anything but bitcoin so we have no interest in making changes for multiple coin support.

what does this mean?:

AMU 57 SendWork usb write err:(-9) LIBUSB_ERROR_PIPE

I'm getting hashrate to build up to 2/3rds the way then half of it shuts off and it stats to reload again until the cycle repeats.  Cannot get everything on and mining in harmony.
