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

[Trongersoll]

i tried getting help in my own thread and mostly got ignored. those that tried to help did in some instances. This thread is much too long to find things. that being said, i'm trying to install cgminer on a virgin Ububtu box. Once i figured out that configure had to be run to compile i've started making progress. I'm now getting the error:

configure: error: Missing required libcurl dev >= 7.18.2

I have libcurl3 installed, but i don't know if that means anything in this instance.

exactly what it says... you DO NOT have a version that is greater than or equal to 7.18.2

as an option you might want to follow the link in my sig where I built a centos cgmining box.

Do you really think this response was helping? I understand that people who regularly do support get tired of, what to them, seems like stupid/simple questions. a proper response would have been to tell me how to get/install the missing part. Implying that i can't read was no help, and referring to your canned installation using a different flavor of Linux didn't help either. I hate to be short with people that i am begging for help, but,  really.

Mining isn't for everyone.  The author of cgminer mostly does this in his spare time, relying on contributions from users to keep the development going.

Linux certainly isn't for everyone.  I'm a computer geek, and I can't stand linux.  Every year or so I try it again, and I end up getting too frustrated with the nonsensical parts of it and go back to Windows.  I simply don't have the time to put into figuring out all the intricacies of linux and figuring out why something doesn't work the way it's supposed to.

So, if you can't figure out how to compile on a platform that requires compiling, you're at the mercy of the linux geeks to help.  If you don't like that, perhaps you shouldn't be using linux.

heh, I'm a computer Geek as well. i got my B.S. in Comp Sci in 1979. I first used Unix as a user in the early 80's. Around 2003 i even wrote a Linux device driver for a specialized PCI board. The thing is i've been retired for 7 years and things have changed. I'm just going through startup pains at the moment. i had never seen ./configure before i was expecting a make file to do the build. Things have change enough that i'm basically starting over with Linux.

git just equals a better/fancy code version repository based on cvs which you may have used

http://cheat.errtheblog.com/s/git

two main commands you want

git clone giturl  (makes a clone of a git repository)
git checkout  branch/verison  (changes to a different branch/version in you local copy of the repository)eg in the bitcoin one master has all the latest pulls(patches) that have been accepted, version 0.8.1 was the lastest release

Hey

Do you know when you will be adding bfl asic or do you only know that avalon works?

[DrGuns4Hands]

3.0.1 took my prior problems with 2.11.4 and 3.0.0 and made them even worse now, instead of getting hardware errors from my 5870 and the other card running fine 3.0.1 errors out before it even starts hashing with a cgminer.exe has stopped working windows.

EDIT:
It appears the crashing out before it starts issue only happens with the 7zip file. The regular zip file starts fine, although it still hasn't fix the GPU1: invalid nonce - HW error  I mentioned earlier. That started in 2.11.4

re-post:
cgminer 2.11.4 and 3.0.0 I get an error GPU1 invalid nonce: HW error on my radeon hd 5870 runs fine under 2.11.3, even looks like it's producing normal hashes on the other 2 versions all the averages look right the 5s and avg  values show what both of my cards together produce, except the 5870 is all HW error's and not sending shares to the pool for that card. Other card is a 7970 if that matters. Running windows 7 x64. Not sure what changed between 2.11.3 and 2.11.4+ to cause this problem.

I'll add BFL SC when I get one

Supposedly posted to me only a day ago ... no idea who got the other of the first 2 almost a week ago - I guess BFL wasn't all that interested in getting the most used miner software working with their devices first (though as I've said before they probably could have had problems sorted a week earlier if they'd started with cgminer first)

I've already written the basic driver, but I don't intend to brick people's ASICs by sending out untested code ... be wary of cheap imitations ...

Thanks for the update and the hard work, ckolivas.

You're most welcome

I just updated my drivers to 13.4, and CGMiner can't compile some of the .cl kernels into .bin files. Specifically: poclbm, phatk, and diakgcn all work, but diablo and scrypt do not. Program just crashes with no error message, but with -D -T --verbose, it is during the kernel compile portion.

Gigabyte 7970
Win8x64
13.4 drivers
OpenCL 1.2 <1124.4>
CGMiner 3.0.1

Doesn't affect me much, as poclbm gives me the best results, but I figured I'd let you know.

Two questions.

1. Can you run scrypt and sha256 on different threads on the same GPU in one instance of cgminer or is a 2nd instance required?

2. When the number of shaders is flagged at a lower amount than available, are only the number of shaders specified utilized?

I'm specifically wondering if, for example, a 5770 could have its shaders halved and 400 could mine scrypt and utilize the majority of the card's memory while the other 400 mine sha256.

Just curious! Thanks!

[bitpop]

You need 2 instances if it works at all

[SkyNet]

Just installed 13.4 and I am getting a very strange behavior.
I am in windows 7 64bit
I am starting the program with the flags, fans spin and so on, mining seems to work however I am not seeing anything in the command prompt window - it is totally blank!
Has anyone encountered something similar?

[Tigggger]

I have a dual 5970 rig but 1 of the 4 GPU's is no good (GPU0)

I use -d 1 -d 2 -d 3 in my command line but when I start cgminer is seems to turn gpu0 on and off a couple of times before finally disabling it and during this cycling the system sometimes crashes.

Is there an alternative way to stop it being used ?

Remove it from your Xorg configuration if you use Linux.

Can you help me figure out what is wrong when I try to use 3.0.1? It is specific to this new version because 2.11.4 is still working. I am on Windows 7 x64 with all the updates and I have a 6970 in it.

Code:

I asked ck yesterday about running two instances from two different directories and he said:

Fine to run two. Just use --remove-disabled as well as -d so both instances
dont try to fight over GPUs.

Thanks. Makes sense.

Any idea about the shaders? I assume it's impossible to target specific groups of shaders and the option is simply for configuration, but I wanted to confirm.

[FiatKiller]

I'll defer to "the man" for that question, methinks.  lol

[-ck]

--shaders is just a hint to tune the program, it has no effect on the GPU. There is some advanced code to partition GPUs with OpenCL to do different tasks, but that is way beyond the scope of what we do with mining, and does not partition some shaders off as such. Mining both concurrently will likely produce lower results than the sum of each at half or at best, just equalling the sum of the halves. I suspect scrypt will kill the btc mining as well so you'll get very unbalanced work in favour of scrypt.

Summary, don't waste your time. Mine one or the other.
