memleak still is present - 2MB per getblocktemplate request.

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!

Could you re release binaries for download? Thanks.

Version 2.4.5

This is a bugfix release to address a memory leak affecting long polling.

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

appreciate your work. Is there a way for a noob to compile scrypt-jane support into your latest optimized cpuminer? Thanks.

Sorry, I don't think so.

K, thanks. I see someone else posted with one that may work.

cpuminer-opt (see sig) supports scrypt-jane and many other algos.


Thank you. Will check into it.

somebody has benchmarks using VIA Padlock engine with CPU miner?
I have a C3 computer in storage, if its worth it I can bring it back to life...

I don't have precise benchmarks at hand right now, but it's definitely not worth it. The performance per MHz is still way lower than that of modern Intel CPUs.

yeah, but the power it uses is very small.......

Unfortunately not small enough. It's still far less power-efficient than a GPU.

@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

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.

I can confirm that ./configure --disable-assembly does in fact work, at least on a pine64 running debian.  Of course, at 2.5 kH/s I'm not really sure it's worth doing.

If at all possible can solo mining for HODL be added? I think the coin has potential, but I don't trust leaving my coins with a pool for a year, which I think is kind of the point - true distributed mining. I would love to have the extra speed without it requiring a pool to mine.

Hey guys, I was curious if there was a way to have cpuminer run a benchmark for all the algos that it supports?  I know I can do them individually but I was hoping there was a way to do it that's similar to the ccminer type --benchmark.

If so, maybe I'm just doing it wrong???

Regarding Hodl, you don't have to leave your coins with the pool for one year; if you are mining with the pool, once you gather 50 HODL, the next block will be mined to your address Smiley

Hi, everybody!

Recently, I cloned a cpuminer for zcash from https://github.com/dakk/cpuminer-zcash . And compile it with MinGW under Windows XP, which is the same system as the target computer.
I have modified the git to fix some issue.
1. Modify Makefile by hand: Change '-std=c++11' to '-std=gnu++0x' to make the function 'strdup' work.
2. Add a portable_endian.h from https://gist.github.com/PkmX/63dd23f28ba885be53a5 and included it into equihash/equihash.cpp to fix errors about 'htole32'.
3. Modified sha2.cpp and miner.h to fix "undefiened reference of 'sha256_use_4way()' "

And I got the binary, with some issue:

    $minerd -o cn1-zcash.flypool.org:3333 -a equihash -u (my.wallet).work1
    [2016-12-13 00:11:30] Binding thread 7 to cpu 7
