cpuminer-opt v3.3.5 is available.

Fixed hodl on Windows with non-AES CPUs. New build procedure for Windows, see README.md.
This fix is only significant for Windows users who compile their own on non-AES CPUs. Cryptomining
Blog does not build binaries for non-AES CPUs.

Rewrote CPU capabilities check to provide more info and be less verbose. It is implemented in permissive
mode meaning that mining will always be attempted. The miner may crash or perform at less than optimum.

This should close any remaining issues for now. It is recommended that all users upgrade even those who don't
like to update every release.

Check CMB or OP for Windows binaries availability.

thank you for the update

mounting drives (is that still priviledged)

Yes, it still is, but modern desktop environments do it for you via mechanism similar to sudo. You just click on 'mount USB drive' button in the UI.

The reason why I suggest using sudo is because doing everything as root is _very_ bad practice -- http://unix.stackexchange.com/questions/52268/why-is-it-a-bad-idea-to-run-as-root

In fact, even for installing most software you don't need root, for example my package manager revolves precisely around that -- https://github.com/hmage/norm

Agreed on the reasoning but I prefer having a root login for the simple reason it requires a second password.
If the user password gets cracked with sudo enabled the whole machine is compromised. Without sudo root
would have to be cracked.

Sudo can then be used to provide limited root priviledges like installling packages and mounting drives (is that
still priviledged) but nothing too dangerous.

My plan is to do a "net" install of Debian, basically the bare minimum, then figure out what I need to type next. Essentially a "step-by-step" from complete scratch/zero. It's in a VM, so no biggie if I have to do over and over just to get it right.

I've been doing Debian minimal netinstalls as part of job for 16 years.

You might want to set up sudo first, debian doesn't install it for you (ubuntu does).

so login as root first, "apt-get install sudo", then run "visudo" to edit /etc/sudoers and add yourself there, then log out and login as yourself.

Then run "sudo apt-get install build-essential" -- it will install essential stuff needed to have a C/C++ compiler that can compile.

After that it boils down to what you need to compile, in case of cpuminer-opt it's "sudo apt-get install libssl-dev libcurl4-openssl-dev libjansson-dev libgmp-dev automake".

My only experience with minimal installs is Centos. It provide the install time options for both
a minimal install and development tools. After that install some of the missing dependencies for cpuminer-opt
then pick off any stragglers when the compiler complains about them. That would make for a pretty lean machine.

But I'm sure Debian can do it just as well.

Does ubuntu have a "console" install? Non-graphical type? Of course I will go to their website. I know how to run a Pi2 a bit, and I think Rasbian is based on Debian, so ... well, that's just what I've been using for 20 years (as a newbie, 20 years a Linux newbie, go figure). Ubuntu is more recent (about 10+ years old), and is also Debian based.

Anyway, queuing download for 16.04 LTS ubuntu 64-bit, desktop and server versions.

Last I checked (many moons ago) the server edition of ubuntu was text only so I'msure they do.
I don't think you need to switch. If you 've been using Debian for so long and you know how to compile
it should be a brease. I only recommended Ubuntu because it's trivial to install and has a lot more
bells and whistles to make it more desktop friendly. Strip that away and it's basically all Debian.

I am proposing a new direction for the CPU capabilities check...

Code:

Checking CPU capatibility...
Intel(R) Core(TM) i7-6700K CPU @ 4.00GHz
CPU features: SSE2 AES AVX AVX2
SW built on Jun  4 2016 with GCC 4.8.4
Build features: SSE2 AES AVX AVX2
Algo features: SSE2 AES
Start mining with AES-AVX optimizations...

More technical detail but last line summarizes for users. Better?
It would also be nice to include the -march flag either as specified
or translated from native. Haven't found a way except indirectly via
build features. Fortunately the ambuguity does not affect the miner's
decision to use AES.

mine with sse2:
core2 -> SSE2
corei7 -> SSE2
corei7-i -> SSE2 AES
mine with aes:
corei7-avx -> SSE2 AES AVX
corei7-avx-i -> SSE2 AES AVX
corei7-avx2 -> SSE2 AES AVX AVX2

My 2 E5 Xeon 2670 dual platform, a total of 16 nuclear 32 threads, HMQ1725 algorithm is only 361K, this is not the normal bar @3.3.4 version

Can you provide more information? Are you saying HMQ1725 on v3.3.4 is slower than previous versions?
Did you compile yourself or use a precompiled binary? Also please post the startup messages showing the
CPU capabilities.

you need the

part
than direkt link :
https://drive.google.com/uc?export=download&id=0B0lVSGQYLJIZVTFNSkZ0elRQZ2M

Still, something like http://hmage.net/cpuminer-opt/cpuminer-opt-3.3.4.tar.gz would be much more convenient.

I don't disagree. But I'll have to spend some time playing with git before I comit cpuminer-opt to it. And that
will have to wait until the development slows. It will happen eventually.

Still looking for an endian.h package that will work with Windows so I can enable hodl on non-AES CPUs.

A little more info for users with early corei CPUs. I found this which lists the mapping between -march
and the processor family.

This help clarify how CMB has built their binaries for Intel CPUs.

They have chosen to only build for CPUs with AES and AVX. This includes:

- westmere (-march=corei7-avx)
- sandybridge ivybridge (-march=corei7-avx-i)
- haswell broadwell (-march=corei7-avx2)

This excludes the following architectures that are supported by cpuminer-opt with SSE2 optimizations:

- nehalem (-march=corei7)
- core2 (-march=core2)

In order to use cpuminer-opt on these CPUs it is necessary to compile from source on that machine using
-march=native which will automatically select the correct architecture for your CPU.

For those who desire to specify the architecture manually please note that in GCC 4.9 and above you may
specify the family name, ie -march=haswell rather than -march=corei7-avx2.

I'm still waiting for feedback from more Westmere and Nehalem users. I presume the lack of feedback means
things are working (or not) as expected.

I still don't have any issues that would justify a new release so I'll wait a little longer.
