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

[kano]

Been a while ... again

My cgminer-binaries git at github: https://github.com/kanoi/cgminer-binaries

3.8.1a/3.8.1bab 3.8.1 recompiled on:
Fedora 18
64 bit xubuntu 11.04 (should also work on Fedora 16 and 17)
RPi 32bit Arch
RPi 32bit Raspbian

e.g. to get the 64 bit xubuntu 11.04 binary:
wget https://github.com/kanoi/cgminer-binaries/raw/master/Ubuntu_11.04_x86_64/cgminer-3.8.1a
chmod +x cgminer-3.8.1a

The 5 others are:
https://github.com/kanoi/cgminer-binaries/raw/master/Fedora18_x86_64/cgminer-3.8.1a
https://github.com/kanoi/cgminer-binaries/raw/master/RPi_Arch/cgminer-3.8.1a
https://github.com/kanoi/cgminer-binaries/raw/master/RPi_Arch/cgminer-3.8.1bab
https://github.com/kanoi/cgminer-binaries/raw/master/RPi_Raspbian/cgminer-3.8.1a
https://github.com/kanoi/cgminer-binaries/raw/master/RPi_Raspbian/cgminer-3.8.1bab

All 3.8.1a are all USB only:
CFLAGS="-g -W -Wall" ./autogen.sh --enable-bflsc --enable-icarus --enable-bitforce --enable-modminer --enable-avalon --enable-bitfury --enable-klondike --enable-hashfast

All RPi 3.8.1bab are BlackArrow Bitfury GPIO only:
CFLAGS="-g -W -Wall" ./autogen.sh --enable-bab

The -g (instead of -O2) means it's a debug build so if anyone finds a problem and has core dumps enabled, it will dump a much more useful debug core.

Note I have binary folders of ckolivas official release files in my binaries git also, for if you can't get to his downloads
To get them you select the folder (e.g. 3.8.1) then click on the file you want then right-click save-as the "View Raw" link.
Also note that the 3.8.1 folder has a linux 3.8.0 release since there is no difference in the linux code, between 3.8.0 and 3.8.1

Important: Read README, ASIC-README or FPGA-README about USB configuration on linux and windows

But i want to tell "What To Use", no "To use what is in not in use".
When i plug the 6USB Erupter, CGMiner stops work if i'm working with the Bitburner.

Well like my daddy always used to say "want in one hand and crap in the other and see what fills up first"

Check the advanced USB options and see if there is a --usb command that does it the way you want it to.  I tell my instances what I don't want them to use and how many of the devices that I do want them to use.

To tell it to use 6 BE's use
"--usb ICA:6,<furydrivernamehere>:1"

I don't know the bitburner interface type/drivername.

Ok! Thank you so much.

The BitBurner Avalon and Bitfury is handled by the AVA driver.
So to say don't use them you'd use --usb AVA:0

Just spotted a bug in 3.8.1 on Windows.

When entering server details on initial startup, if a mistake is made and characters deleted, those wrong chars and backspace control codes are saved in the cgminer.conf.  On next startup the .conf is declared corrupt. 

[Aurum]

It's funny that example.conf included in 3.8.1 is for GPU mining 

Long Live Scrypt Mining !!!

I recently noticed that if you generate a share over 1 billion, cgminer shows it like this:



Lol, what is that ?  1 Giga-difficulty?  Maybe a 'B' would be more suitable

I think it's a googol.

Wowsers that's a large share.  Grats!

As Kano linked in the wikipedia article, that is the correct official suffix for billion, you're just not used to seeing values that large suffixed with a letter.  

EDIT: Prefix/Suffix, whatever...

Damn, I was hoping the guy who suggested it stood for Googol was right, and it was a REALLY big share  Ah well...

EDIT:  I still think you guys have this one wrong.  We are all familiar with 'G' as the prefix for a billion in the context of a "giga<unit>" of anything - but in this case there is no unit.  It is just an abbreviation for (in this specific case) 1.31 billion.  Talking about a share of difficulty 1.31 'gigadiff' makes no sense at all.

That being said it is obviously just a nitpick.

So sad it's coming to its end of support. Nevertheless we enjoyed the program so much.

You do mean to refer to Alt-Coin support? Correct?

When entering server details on initial startup, if a mistake is made and characters deleted, those wrong chars and backspace control codes are saved in the cgminer.conf.  On next startup the .conf is declared corrupt.  

I'm pretty sure I noted that somewhere. cgminer won't allow any key stroke mistakes. I always end up going to the config file and clean the backspace charactors out and restart cgminer.


On another note WHEN THE FUDGE DID 3.8.1 COME OUT. I was just going to post my anger with 3.7.2 with my eroupter doing the solid light thing and I see that's out on the top of the forum. I'll brb later to see if it fixes it. I'm not getting errors in cgminer but they are doing something with 3.7.2

Edit:: btw what happend to cgminer-nogpu.exe 3.8.1. doesn't have it. How many pages do I have to go back to see what new commands I need to do? I've got this post set to email on update and I'm not getting updates.

edit edit::::: Apparently I just let it run it found the config file and went. I had this bad feeling I was going to have to look for how to disable cpu mining since I thought that was one reason they were separate.

CPU mining was taken out a long time ago so you'll never have to worry about that. The reason 3.8+ no longer has a separate nogpu executable is because GPU mining was taken out.

Ok wasn't aware of that issue. Will look into it at some stage, but I'm trying VERY hard to not release anything new anytime soon.

It's been a hell of a ride getting this far with massive overhauls in the last few months, but it's all about looking to the future. Just think, pretty much 99.9% of the bitcoin network hashrate contributed to by cgminer is coming from hardware that did not even exist one year ago. All of the FPGAs should be switched off by now due to inefficiency and by early next year, 1st generation ASICs will be unprofitable to run too. By the middle of next year, 28nm technology efficiency will be the minimum requirement to be worth mining bitcoin so I have to concentrate my development efforts accordingly.

Such a pitty to see scrypt mining gone.
Majority of Alt Coins is scrypt based - would there be any plans to support it again in the future?

GPU bitcoin mining doesn't make sense for a while now and it's obviously the way to go...

It's no big tickle, just reporting it as I saw it.  Now I know about it, I can work around it by fixing the .conf manually.

No

I am making a conscious decision and taking a stance to only support bitcoin by doing this and will consider all discussions regarding alternative cryptocurrencies as offtopic from here on.

That should have already make it clear what my position is regarding altcoins. Deprecating GPU mining wasn't to get rid of the GPU bitcoin mining code.

I got an unexpected result in a 3.8.1 test, possibly of interest, posted as an update a page or so back. https://bitcointalk.org/index.php?topic=28402.msg3547969#msg3547969

Edit: update - AMU5 went zombie about 7 hours into the present 3.8.1 test (Win7 64 executable). It stayed as AMU5 when unplugged and did not recover when replugged. A "Q" and restart fixed it - somewhat brute force though.

I informed the authors.
I modified an old version of cgminer (3.2.0) to use it with FPGA boards for Litecoin. Source here:
