Topic: OFFICIAL CGMINER mining software thread for linux/win/osx/mips/arm/r-pi 4.11.0 - page 15. (Read 5805649 times)

newb question so I apologise in advance:

What coins does CGminer actually support, where can I find this information? I cannot seem to find it anywhere?

Ah, it seems that the said cgminer version for openwrt was created some years ago with this fork: https://github.com/kanoi/cgminer/tree/ants1-4.9.1c-e6ad32a
as was announced then here: https://bitcointalksearch.org/topic/how-to-compile-cgminer-for-antminer-s1-1249569

Anyone happen to know if I run CGMiner solo (w/ btc address) and point to a pruned node without a wallet, would the miner still receive the block rewards or is it based on bitcoind wallet address?

And as I said, I have no idea about opkg packages. I have nothing to do with their maintenance.

Maybe you got me wrong: I mean whether there is a newer binary version of cgminer available for the openwrt platform, ie. as a opkg-package.

Well that would explain the breakage then. No idea about opkg versions, but additionally I don't believe any of the antminer forks remotely tried to stay in sync with the master cgminer.

It's cgminer version 4.7.1
Is there a newer openwrt opkg version available?

A harmless bug, but a bug yes. Are you running the current version?

But why did the software do that? Isn't that a bug?

You are always mining at the current network diff when solo mining so any "shares" submitted are effectively considered the network diff so any rejects will be shown to be at the network diff as well. "Diff shares" is number of shares (in this case 1) multiplied by the difficulty you're mining at (in this case network diff). You definitely didn't even get close to the network diff but the software decided to try submitting a share anyway and it got rejected. You can see what your best share was, it was only 26,500 when network diff is 708 billion.

Hi,
while solo mining I got this log entry:

Does it mean I missed it by the decimals??? :-(


UPDATE: today again such a case happened:

Can the author or anybody else please tell me why and what's going on here? Thx

I need to compile the recent version to be run on AntMiner S1.
On the S1 there is not much space and also no gcc compiler installed.
I can compile it on the PC, but then I wonder if I need a cross-compiler since the target HW seems to be MIPS?

EDIT:
Ok, I finally figured it out: one of the methods is by using qemu and starting a linux mips distribution therein, and then the usual steps to build the binary...
Since qemu is an emulator, everything runs much slower, but no problem, I'm currently compiling it...

Dear CK,

I am experiencing a Segmentation Fault (core dumped) error when trying to write config file in version 4.10.0.   (I do not have this error with version 4.9.2).  

(it seems to write over cgminer.conf with an empty file, then crash)

I am running on R-PI, ARCH.    

Any advice?

Thanks!

All 32 bit programs run on 64 bit windows.

I am a total noob when I comes to this miner, I tried to follow the instructions to the best of my ability but it tells me it is a 32bit program and I have win10 and 64 bit.  does anyone have this program completed and runs on a 64bit

I think there is a big bug in cgminer's driver-icarus.c:

ICARUS_UNUSED_SIZE is defined as 16. IMO this should be 20.
ICARUS_WORK_DATA_OFFSET is defined as 64. IMO this should be 68.
(there are maybe even more wrong values)

Can you verify/confirm this?

So, have all the miners who use cgminer with icarus devices been misled?

BTW. the source code of this program is really a PITA to study :-(

No need to think about it.

Video Cards have not been supported for years now.  Please read the top post, or the readme that comes with the software.

I think video cards are not supported anymore in latest cgminer.
My tip: learn it first with a cheap USB stick miner (333 MH/s) --> configure with the parameter --enable-icarus
The method is similar with the bigger machines.

Please help me because I do not know what to do anymore.

I made you a small video with CAMTASIA and you can see it from here; https://streamable.com/44t8f

If you can not see it then you can download it from here; https://ufile.io/fjdd3

That way you will understand my problem well. I've just put everything you need to know including the cgminer version and my video card.

I hope so much that you can help me

I look for answers as soon as possible

Thank you

I have the above output. I think the "connected to" is a bug in this version
as the connection to the local bitcoind server works fine.
And I'm not sure about LP (longpolling), but the bitcoind I've running is the
latest git version, so IMO it should have LP available.

Btw, what do the outputs MH0...MH10 mean?
