I downloaded the 32-bit windows one, and got a trojan alert on open?!

Most Windows AV trigger on the 32 bit minerd because it is often payload. That is, instead of doing due diligence and identifying the actual trojan code it simply identifies a legitimate program that is often placed onto the victim's machine by the actual and separate malicious code. That the 32 bit version will work (albeit not as efficiently) on a 64 bit platform means the script kiddies package the 32 bit minerd for broadcast, thus the 64 bit minerd doesn't cause false positives.

Heads up all:

https://bitcointalksearch.org/topic/m.1532516

The 64-bit cpuminer 2.2.3 windows binary in the zip file on the OP has been tampered with.  Unless you specify the username/password in a specific way, it will ignore your settings and instead use built-in creds.

Cheers.

burside, thank you very much for letting me know. I must have uploaded the wrong binary for the 64-bit Windows version of the miner. That version was compiled for internal use only, and never intended for public distribution. On the up side, that default address would never have worked from the outside of the private network it referred to, and when mining in a pool people notice immediately if shares don't show up in their account, so the only problem this could have caused is that getting the binary to work was trickier because you had to use the --userpass option instead of --user and --pass.

Unfortunately I'm currently away, so I'm unable to recompile the binary, but luckily there's not much difference between 2.2.2 and 2.2.3 apart from the benchmark feature, so for the moment people can just download version 2.2.2, which on Windows should not be any slower.

Miners who are currently using the "wrong" 64-bit 2.2.3 binary with no issues need not downgrade. There is no risk that your shares go to the wrong server or account, it's just that when you first set the miner up it may be a bit trickier to get your credentials to work, as in that binary not all of the command-line options for setting the credentials work as expected.

Really glad it wasn't something more nefarious.  Thanks for the quick reply!

Hello, pooler! If there any chance to specify failover credentials in the miner itself? I'm aware of scripts index.php?topic=74941.0 and  index.php?topic=46.0  but I think this should be implemented in the miner itself in case if development is not halted.
Thanks for such a great miner.

I actually encountered and fixed this last night. If you have Homebrew installed on your machine, just run:

brew install libidn

When it finishes, you may have to create some symbolic links to the library, but you'll have a copy on your machine at least.

I'm trying to mine LTC on OSX, following all the instructions on the text file of the CPUMINER (minerd). When I run ./MINERD.sh I keep getting this error:

dyld: Library not loaded: /opt/local/lib/libidn.11.dylib
  Referenced from: /usr/bin/minerd
  Reason: image not found
./MINERD.sh: line 1: 12464 Trace/BPT trap: 5   

Could somebody give me a hand in order to solve this? I'm using Mountain Lion (10.8.2)

Thank you in advance.


it cant load the library libidn who should be at /opt/local/lib/libidn.11.dylib because it dosnt exist.
error reading is easy Wink

I'm a newbie Wink

Could you just let me know how to download/install the libidn library?

Thanks
no since i didnt google ur problem, nor am i a MacOSX user.
Even a newb can google, thats no excuse.

I googled extensively and I couldn't find a solution - that's why I'm asking to the more experienced users in the forum. I wouldn't lose my time (and other's fellow bitcoiners time) asking in a forum if the answer was easily found googling the problem.

ermm.. you do CPU mining to utilize all the idle CPU power of your desktop PC don't you ? :O

I'd love to see what a quad socket 64 core Interlagos system would pull in. Not that it'd be efficient, a GPU would be far better, but just to see the numbers.

Interlagos is basicly a set of Istanbul CPUs, so here - calc yourself. ;-)

I think he means a quad socket system with 16 core cpu's for a total of 64 cores.

yeah get an $800 motherboard and what; $600 cpu's and a 1000 watt psu?

the top end 16 core Interlagos is a bit more than 600 though. On the plus side, I've already got a LEPA 1600W power supply I don't need to buy.
