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

[kano]

i downloaded the https://github.com/kanoi/cgminer-binaries/raw/master/Ubuntu_11.04_x86_64/cgminer-3.1.1a and i'm using xubuntu 12.10. I'll only need cgminer for ASICMINER usbs.

i'm getting this error :

Code:

./cgminer-3.1.1a: error while loading shared libraries: libOpenCL.so.1: cannot open shared object file: No such file or directory

if i got it right opencl is for GPU mining, that i will not need. So how may i use cgminer or bypass the error? Thanks.

look at what you downloaded ...

cgminer-3.1.1-x86_64-built/cgminer-nogpu

Edit: oops sorry you downloaded my 11.04
OK - that's compiled specifically for GPUs
No reason to be mining on 11.04 unless you have GPUs

Get the master ckolivas version (you'll need it on 12.04 anyway)

oh right, my fault.
in the meantime i decided to build from source.

Used this :

Code:

CFLAGS="-g -W -Wall" ./autogen.sh --disable-opencl --disable-adl --enable-icarus

Is that optimal ?

I think i made it fine. Haven't tested in mining but at least it is executable.

Yeah when I saw 12.04 in your post I assumed you were using ckolivas binary.
Sorry got that mixed up.

But since you are using 12.04, you will need to use the ckoivas binary anyway.

ckolivas, I finally got my rig to error out again with verbose mode turned on.

Here are the errors:

And here is the log file:

I hope this helps you. Thanks!

Thanks. That gets us part of the way there. At least I know what it is likely trying to do when you have the problem. Do you know what happened at that particular time  [2013-05-31 14:04:07] on your machine? Did your IP address change, did you have network outage, did your ISP go down, did the pool go down? Did you delete windows in disgust and install linux to fix this?

I checked the router, and it didn't hang up or change IPs. The windows box has a static IP.

One other thing that might help - All machines mining on this particular internet connection would fail, not just this one. (They are all windows boxes)

That's the best I can tell you for now.

I haven't gone into the Linux world yet to mine because its been years, and I think I have been demoted to noob status again.

I probably should switch to linux though.

when the new version of cgminer will come out?

New version 3.2.0 - 31st May 2013

Major upgrades to virtually all FPGA and ASIC drivers. Nothing much here for GPU miners.This version changes all the drivers to the direct USB mode so linux users will not need any drivers and all devices should now hotplug,that includes Avalon. Windows users will need to remove the ftdi driver for the ancient serial USB mode and use a tool like Zadig to associate their USB devices with the WinUSB driver (which is an official Microsoft driver). The code for all devices is built into the binaries I have uploaded except for Avalon on windows (but why on earth would anyone want to do that?).

Huge props and thanks to Sitarow for virtually unrestricted remote access to his avalon and Xiangfu to sponsor the Avalon development.
While the code is now heavily tested, being such a massive update, there may be new bugs.


Human readable changelog.

- Clamp initial GPU fanspeed to range provided by user.
- Update screen completely when going into a menu entry.
- Shut down/restart more reliably.
- Shows pool difficulty change in logs if it changes via stratum.
- Less locking around some of the stratum code may prevent some rare hangs or delays in processing stratum data.
- Decrease the amount of ram and threads used by stratum share submission to minimise the risk of running out of resources to submit shares.
- Fixed small memory leaks.
- New option: --lowmem            Minimise caching of shares for low memory applications
- Increase timeouts for windows comms.
- New windows DLLs for updated libcurl
- Major rewrite of icarus driver to move to direct USB.
- Rename of all devices to tell them apart.
- Massive changes under the hood supporting all the changes, along with bugfixes and improvements.
- Major rewrite of all the Avalon driver:
. Uses direct USB to the chip removing need for ftdi driver and its heavy polling which decreases overhead.
. Uses separate work submission and result parsing threads from the main hashing thread, to guarantee adequate work is submitted to keep the device busy, and ensure no results are lost due to receive delays or buffer overflows.
. Parses results using a buffered + scanned mechanism to avoid getting out of sync and needing to reset the device to recover. It can also discard garbage results without them affecting further results.
. More reliably detects hardware errors: The count will now appear higher due to "NMW - no matching work" being counted as a hardware error which it truly is.
. Idles the device if there is no work due to pool or network outage to avoid wasting unnecessary power.
. Disables the device gracefully and can hotplug it again if it is pulled out/plugged in via USB.
. Monitors temperature more reliably to adjust fanspeed by checking values returned more rigorously.
. Decreases the amount of memory in use by the device.
. Avoids run-over to start repeating results through much better timing of submitting new work.
. More reliably detect conditions that require an FPGA reset thus decreasing the number of resets but is more likely to recover when a reset occurs.
. Now displays ambient/operating temperature and fan %/RPM in the text user interface when run on a PC/console.
. Can start an avalon mining without any options being passed to it.
. Documentation of avalon options in ASIC-README.
. Numerous other low level bugfixes and improvements.

- Create a logwin_update function which mandatorily updates the logwin and use
it when input is expected to prevent display refresh delays.
- usbutils force an unknown IDENT for zero
- icarus set default options/timing based on device
- Must unlock curses as well in logwin_update.

it when input is expected to prevent display refresh delays.
- icarus report usb write error information
- Add name to icarus copyright notice.
- Check for *pth dereference on pthread_join
- usbutils name latency correctly
- Check for restart before buffering more reads in Icarus.
- Icarus should timeout if it's greater than the timeout duration even if it's
receiving data.
- We should check for amount buffered in icarus get_nonce against amount already
received.
- Make mining threads report out during work submission.
- submit_work_async is no longer used directly by driver code.
- Fix first read timeout on icarus get nonce.
- Retry icarus_initialise if the first read attempt fails.
- Properly pthread_join miner threads on shutdown.
- Properly pthread_join miner threads on shutdown.
- Use a persistent single separate thread for stratum share submission that uses
workqueues since all stratum sends are serialised.
- All stratum calls to recv_line are serialised from the one place so there is
no need to use locking around recv().
- Only allow the mining thread to be cancelled when it is not within driver
code, making for cleaner shutdown and allowing us to pthread_join the miner
threads on kill_work().
- Only allow the mining thread to be cancelled when it is not within driver
code, making for cleaner shutdown and allowing us to pthread_join the miner
threads on kill_work().
- Set pool->probed to true after an attempt to resolve the url via stratum code.
- icarus test nodev everywhere
- usbutils/icarus separate FTDI transfer values and more debug
- add icarus to hotplug
- usbutils add rest of icarus
- simple serial-USB python test script
- icarus->USB v0.1 incomplete - missing initialise()
- README spelling
- Update documentation for icarus switch to USB
- Add USB rules for supported USB devices
- switch icarus configuration to usb
- usbutils new command for icarus
- usb add a numeric sub-indentity for each name
- usbutils - make FTDI handling automatic
- fix duplicate name
- usbutils set Black Arrow Lancelot's as BAL and match the lot->llt name
- usbutils identify Icarus devices
- libusb_control_transfer 16 bit words are endian specific.
- usb_applog separate amt display
- Show pool difficulty more verbosely if it changes via stratum.
- Attribute whatever stats we can get on untracked stratum shares based on
current pool diff.
- Provide a --lowmem option which does not cache shares on failed submission to
prevent low memory hardware (eg Avalon) from crashing.
- Update util.c

Nice! Thanks for your efforts....

We are able to remove -S now right?
Mine isn't detecting them. I have 20 BLT.

http://screencast.com/t/OGXeioWqyw

It's actually disconnecting and reconnecting all the USB devices. Some are failing with port reset failed and aren't coming back up.

Yes there is no -S any more. I assume you're not plugging them into usb3 ports? They have problems for reasons we haven't worked out yet.

[bitpop]

Yes I already switched to usb 2 because 3 failed at way lower devices.
Do I need to install winusb? What is that? Right now I'm using the latest FTDI driver..

Yes, as I said in my announce post. The FTDI driver is completely unused by cgminer now. Use zadig (you can get it from my cgminer directory) to install winusb driver and bind it to those devices.

Wow thats a big change. Thanks. Windows users may find this way harder because they are used to real plug and play.

Windows users, do this. Choose one device and replace it with WinUSB, it will replace all similar devices.

http://screencast.com/t/Gep6djxM

The best solution for this is to use a tool called Zadig to set the driver:
 http://sourceforge.net/projects/libwdi/files/zadig/

This allows you set the driver for the device to be WinUSB which is usually
required to make it work if you're having problems

With Zadig, you may need to run it as administrator and if your device is
plugged in but you cannot see it, use the Menu: Options -> List All Devices

You must also make sure you are using the latest libusb-1.0.dll supplied
with cgminer (not the libusbx version)

Bold: What does this mean? There are 3 options, WinUSB, libusb and libusbK. First it says use WinUSB but the bold says to use libusb. Which one is right?

Use WinUSB. The libusb-1.0.dll is already in the cgminer zip folder and it's telling you not to install a different libusb dll.

FTDI is not plug and play for most people either by the way.

[bitpop]

I don't know what that means. We aren't even using libusb. Is there a reason someone would use libusb vs WinUSB? And that would be the reason to tell Zadig to use your dll and not theirs?

Don't even think about libusb. Pretend we never mentioned it, it's all something cgminer does internally and you need not worry about it.

[bitpop]

Lol ok, please cater us OCD people. I'll try to ignore it. Ok drivers installed. Everything is perfect but one thing, it hashes with 20 devices but only shows 2.

Ok restarting cgminer finally shows them all. Might be a cache thing or a bug?
