OFFICIAL CGMINER mining software thread for linux/win/osx/mips/arm/r-pi 4.11.1

[Fiyasko]

Yay the 2.9.4 works great with stratum and eclipse!

Hashpower has LP again!

Everything is working as expected.

That's what I like to hear.

Do be careful though. That poison known as GBT may strike with unexpected bugs if one of your backup pools uses GBT.

Best current compromise is to use as many stratum pools as possible with their direct addresses and add --fix-protocol in case one of your backup pool uses GBT.

Bottom line: I really regret even implementing GBT for cgminer, as it was a lot of work, introduced a new set of bugs, and has earned me zero donations despite a lot of work. I'm seriously considering just disabling or even backing out GBT support.

Gosh guys, Do we Not have a donation address for ckolivas? When there was the change from 2.7->2.8 and we got that Totally Uneccesary "Best Share" stat, I'd of set my donation to 1% for two days.
I really think that CGminer should have a Prompt of "Could you please help the developer by enabling .001% hashrate donation? There are no side affects"

Seriously, Back when CGminer prompted for "donation set to 0%, Please consider atleast 0.00x% :"(" it made me want to donate, Im sure that if Ckolivas Gets SOMETHING for doing all this work, Then he'll continue the work.

What would you all do if CGminer just Stopped being updated? For awhile we would all be just fine, But imagine if it was discontinued Before stratum, Or even before LongPolling
Just donate!

You mean the poison known as "conman implemented his own GBT from scratch and it's full of bugs because he never read the spec and made a lot of poor assumptions that don't hold true in practice".

[Joshwaa]

Too early for FUD!

I swear I would donate a lot to see Con and Luke in a UFC match.. I would say Kano could referee but that might be unfair. Lol

[dietwice]

Imho it would be great to have a command line switch just to disable GBT and stop worrying about which one of backup pools had accidentally enabled GBT support.

I'm pretty sure the donation feature was removed before 2.7.

[P_Shep]

So the the back-up pools getwork every 60s, while the active pool gets work when it needs to.
Why doesn't the back-up pools get work when the active pool gets it?

For my stratum pools, I find the active with, say 9 getworks, the backup has 50.

Yeah it was, I meant to say "I would've" and it looked weird so i removed it, Changed it to "i'dve" and "i'd've" both looked wrong, And i forgot to finish it

Actually I somewhat wish people would donate more for stratum support and no one donated for GBT support and I could disable that steaming pile of shit protocol. I might just disable it by default and add a command line to enable it instead. This is the reason I implemented stratum support first, to demonstrate how much better it actually was and show my support for the superior pool mining protocol, and I was hoping gbt would just go away.

So by including support for GBT, you're making it an option for potential miners, but secretly hoping it goes away. Sounds like you've already made up your mind.

Post two bitcoin addresses, one for donations from those who want to show support for stratum, and the other for showing support of GBT.  That way people can "vote" with their wallets.

I already made about 50BTC from a few generous poolops showing their support for me implementing stratum, since it's clearly benefiting the pools even more than it is the miners.  That's some battle GBT has ahead since it's currently at zero... Anyway if someone does donate for GBT in the interim, please tell me that's what you're donating for, since I can't set up a wallet address right now.

Hi guys,

Sorry if this sounds a bit noobish, but I can't find the answer anywhere. My problem is this: I can run cgminer on my rig (headless) no problem, but I get a "devices don't match/multiple monitors/ run gpu map" error when I start it, and I'm unable to change/apply any settings apart from intensity, even if I put them in my config file it won't load them. Also, by the time I start to read the above error message it's gone! so I never get a chance to read it entirely. This is also true when I start cgminer with the -n flag, it briefly flashes the result on screen before disappearing, not giving me a chance to read the result. If I add the "pause" command it scrolls past the results and asks me to press any key to continue. I've tried using the logfile.txt command but it's blank.

Is there any way to keep the cgminer window open long enough for me to read it? It's strange, as the very first time I set cgminer up it worked a treat, but after a reboot it's never been the same. I'm quite new to this game, and very new to cgminer, so any help/advice would be greatly appreciated.

Start cgminer from a dos prompt instead of a bat file or clicking on it and the dos prompt wont disappear... Also add -T and it will just scroll the text output instead of formatting it.

Thanks. Core dump or debugging output is not much help without debugging symbols. Either build with the debug symbols (add -g) or grab a debug build from
http://ck.kolivas.org/apps/cgminer/debug/

Done.

Thanks muchly. Most helpful it will be.

Heh, sorry, it's been 13 years since I used windows in any capacity...

[jborkl]

Is it possible to implement/integrate stratum direct for solo mining. Or write/rewrite the proxy to launch with cgminer?

I know how to borrow stratum or longpoll, but I do not prefer to.

Windows

Wondering if it is possible. Thank you

No problem it has been almost exactly the same here (whenever RH 5.2 came out 98-99??) since I went linux but you have definitely taken those linux skills to a level I have not got too yet..

Thanks for the reply ckolivas,

Yup, tried that too - still disappears too quickly to read it....even with the -T flag.  Been a few years since I used DOS, but I'm sure this is right:

START Users\<User>\Desktop\Mining\cgminer-2.9.4-win32\cgminer.exe

The miner starts, then I get a very fast error message and it closes......

I'm doing something stupidly wrong here.........

Run:  cmd

A black window with a prompt will pop up and not go away.  At that prompt, run cgminer.
