Is there a version of this miner which supports the ScryptJaneNf16 algo?
This latest version  2.4.2 supports it.  Scrypt Jane A.K.A scrypt-chacha
You must be thinking of some fork. The miner discussed in this thread only supports scrypt and SHA-256d.

Yes, my mistake, my version is cpuminer-2.4.0. I'm pretty sure it's from here:  https://github.com/milancoin-project/cpuminer

Trying to compile, but getting errors:

./configure: line 6517: syntax error near unexpected token `,'
./configure: line 6517: `LIBCURL_CHECK_CONFIG(, 7.15.2, ,'
See the FAQ in the first post.
Thanks, the FAQ did enable me to get it compiled, and I verified that it doesn't include the ScryptJane branch.

there is some problem in block version
Unrecognized block version: 4

on latest bitcoin wallet 0.11.99

Thank you for pointing this out. I've just pushed a commit to the git repo to support the new block version.

I'm using the Bitcoin version v0.11.2 (64-bit) and I'm having the same issue with the blocks... Sad

That is normal. This is a command-line application, it has no graphical interface.

Version 2.4.3

  • The miner can now take advantage of the VIA PadLock Hash Engine (PHE), but only in 64-bit mode.
  • Version-4 blocks are now recognized.

The source code is, as always, available at GitHub. Source tarball and binaries are available at Sourceforge.

so i've been toying with a fork of the most current bitcoin source code, and im trying to cpumine the new genesis block and 1st block after..

Code:
./minerd -a sha256d -o http://127.0.0.1:8228 -t 1 -u rpcuser -p rpcpassword -D -P
[2016-02-05 12:33:00] 1 miner threads started, using 'sha256d' algorithm.
[2016-02-05 12:33:00] ...retry after 10 seconds
[2016-02-05 12:33:10] ...retry after 10 seconds
[2016-02-05 12:33:20] ...retry after 10 seconds

odd thing is, i can telnet to that port and see its open, but the miner doesn't seem to care what my rpc user/pass info is, because ive even entered the wrong info and it just does the same thing..

i get no info from -D debug either..

*update

so i used a binary from the sourceforge site:

Code:
./minerd -a sha256d -o http://localhost:8288 -t 1 -u rpcuser -p rpcpassword -D -P
[2016-02-05 15:27:18] 1 miner threads started, using 'sha256d' algorithm.
[2016-02-05 15:27:18] JSON protocol request:

Aren't there memory leaks in cpuminer 2.4.3 win64 version? Its virtual memory increases roughly 4GB per day while mining 1MB blocks. When remote node restarts these GB disappear and miner then tries to resolve host with four random characters even it was configured to connect at 127.0.0.1.

You are right, I just checked and there is indeed a memory leak in the GBT code. I'll push a quick fix to GitHub shortly. Hopefully I'll also be able to publish new binaries soon.

I ran into this a few days ago, it's quite relevant: https://www.reddit.com/r/ProgrammerHumor/comments/479o3r/open_source_documentation/
While I agree that the proposed "fix" is rather harsh, one could argue that if you don't know what a CLI is then you almost certainly don't want to run cpuminer, as nowadays its practical uses are limited to stress testing and to the debugging of other mining-related software.

@pooler
I contacted u a few days ago by email about scrypt_core() for aarch64, I don't know how to code a .S file but I came up with a temporary solution:
A fallback written in C++ for unsupported architectures.  
simply place the fallback before the others in build order and it would compile, and be replace by optimized version if the architecture is supported Smiley
This file is critical to my build of Diamond wallet.
Your scrypt-arm.S file will not build on aarch64.
This is ONLY thing stopping build Sad
https://bitcointalk.org/index.php?topic=580725.msg14296622#msg14296622
Like I said if I had C++ source I could get it to run (likely slower).

As I've told you in my email, I still haven't been able to test cpuminer on aarch64, but time allowing I plan to look into this soon.
If you're OK with an unoptimized build, I think as a temporary solution configuring with --disable-assembly should be enough.

This is a bugfix release to address a nasty memory leak affecting getblocktemplate mode since version 2.4.

The source code is, as always, available at GitHub. Source tarball and binaries are available at Sourceforge.


Thanks for a release, but memleak still is present - 2MB per getblocktemplate request. I also see lowered I/O and page priority values, that looks better.

Why is this reported as a threat? I cant even download it, chrome and firefox are going red!

I also saw that red warning, you should be able to ignore this warning and download this software. It is marked red because it is easiest way for antivirus (or virus that detects other viruses) to identify that your system is compromised. Usually antivirus detects miner executable but main virus remains in system.

I must have missed this one because it only happens when long polling is enabled. Anyway, I've just pushed a fix to the git repo. Thank you again!
