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

[Askit2]

Yasm is not needed anymore as CPU mining is no longer supported and the CPU code will be ripped out of Cgminer soon.

Referring to that windows-build.txt file you were talking about, did you modify the package config file for curl as directed?

Edit: It could be what C. Kolivas said, but I would check the package config file first.

Yes, About 5 sucessful builds ago. Then upon trying to build a 2.9.3 from git so that I could try stratum on Eclipse(Still didn't work for me) I had that error. Altering the file mentioned in the link did in fact let me build it. As I had built with this setup and no changes 2.7.5. It is running but eclipse US1, 2 and 3 are all marked dead on stratum.

EDIT: Flags used are in windowsbuild.txt.
CFLAGS="-O2 -msse2" ./configure --enable-bitforce
Then per instructions:
make

Removing LIBCURL_CFLAGS@ from makefile.am and using ./autogen.sh rather then autoreconf. One or both fixed it.
This is win7 64bit. Maybe my XP 32 (initially only XP....) machine would do it easier.

Well - having written about 1200 lines of new code (still not complete) for direct USB support on the MMQ, latest git+my changes compiled fine first time on mingw for me (after adding libusb) on WinXP32 - no issues.
Odd.

(Edit: P.S. I used:
CFLAGS="-g -W -Wall" ./autogen.sh --enable-modminer --enable-ztex
make clean
make
Like I do in linux)

Incidently, I'm now running a debug version (stock 2.9.3) on my router. Hopefully the core dump will tell us what's going on.

Of course, now I'm running the debug version, it's running perfectly.

 

[-ck]

Well, anyone got any bright ideas about windows and stratum? Disabling threading didn't help, debug versions spit out no debug info, and it's not like I can just tell people to fuck windows off and start mining only on linux. Even after ASICs arrive, someone somewhere will still want to mine with windows.

Windows people, any ideas? Was there a version with stratum that was stable for you across multiple disconnections?

I haven't given up on this yet.  Using procdump, I was able to get this:

I thought 2.8.7 behaved the same, but it doesn't.  With 2.9.3, I can fire up cgminer pointing to oz, unplug the NIC, and in about 30 seconds in crashes.  On 2.8.7, it recognizes it fails and tries to switch, but fails on the switch, as it suddenly says the same pool is alive (can't be, NIC is still unplugged), but it does recover after I plug the NIC back in:

Here's something interesting!  Using 2.9.3 with --verbose, it doesn't crash!!!  I still observe the same oddity as in 2.8.7 where it says pool 0 is no responding, then it says it's alive again.  Since the NIC isn't plugged in, it can't do anything, but it does not crash.  When I plug the NIC back in, it successfully recovers.

Using -T doesn't change anything, it still crashes.

Hopefully this helps!!

EDIT: It seems the problem isn't just with stratum.  I have two miners pointing to p2pool (which is LP), and both locked up (but didn't crash) when p2pool wasn't providing work fast enough.  All on 2.9.3.

Thanks for your dedication to this project. I'd like to request a new load balancing option. 1 device per pool. I'm concerned about pool stability once ASICs start rolling out.

From my experience with cgminer, load-balance and balance do not really distribute work evenly across pools. I'd like to define a list of 10 pools, and each device mines solely on one of the pools in that list. If one of the pools fails, the device attached will move on to the next pool in the list.

Thanks!

This can already be done just by running multiple instances of CGminer.  While it's not the most elegant solution, it is far easier than asking Con to add or rewrite code.

Yes that's already my backup plan, but I'd much rather monitor my miners from one instance vs n instances.

--verbose works! I unplugged my wireless adapter, and it disconnected. Waited about 60 seconds, plugged it back in, and it reconnected. No crashes. At least we have a temporary fix!

That is most interesting guys, and at least gives me a lead! I appreciate your testing and input. This is what free software and open development is about.

Well it looks like in every case where there's enough details, is seems that a null (or corrupt) pointer is being used.
(Well one clearly said it was a null pointer, the others could be that or a corrupt pointer)
The "--verbose fix" is most likely a memory rearrangement that hides the problem.

I tried my memory.h on windows yesterday and made the changes necessary to work on windows also.
Only problem of course is that a solitary null/corrupt pointer wont be picked up by my memory check code.

I guess I'll also have a go at trying to find it ... soon ... if I ever finish this MMQ USB code
... trying to get it to work on windows at the moment

[Luke-Jr]

I wonder if this crash affects BFGMiner...? (If not, then it's a simple matter of finding out which bugfix Con hasn't merged)

Think it's related to it trying to use the pool after it's clearly dead?

Alrighty, I found some time to look at the code and think I've found something hopefully. I'll try to spin something up soon for you try.

Try one of these builds again:
http://ck.kolivas.org/apps/cgminer/temp/

Interestingly if this is the actual bug, it should be possible to hit it on linux as well, but it seems to be much harder to hit because linux can easily tell when the socket has dropped out.

[Schleicher]

This version doesn't crash. At least not within two minutes after disconnect.

I unplugged my adapter, and it kept going. No crash.

Confirmed, does not crash.  It also recovers properly once I plug the NIC back in.

I still see the same oddity with it saying the pool that just died is now active, even though the NIC is still disconnected:
