is there a way to statically build/link the miner (linux) ?

i wasn't able to get it running

A native build is always prefereable to ensure you're taking advantage of all the optimizations supported
by your CPU.

Describe the problem you're having. Does it fail to compile, or fail to run after compiling? Post any error
messages.

hey joblo, i run a windows 32 bit machine, considering the sw is for 64 bit i can't use it, is there a possible workaround ?

No and it's not worth it if there was.

probably time to upgrade the computer/OS or replace it entirely. If the CPU is indeed 32-bit, then mining with it will be academic at best. Latest Intel 32-bit CPUs didn't handle thermal design very well, and overheating was quite common in the high clockspeed pentium 4's. Latest AMD 32-bit CPUs lack support for SSE2, which this miner also uses quite heavily.

If you have a 64-bit CPU, but are using a 32-bit OS...upgrade your OS.

Hi Fuzzballs, didn't expect a visit from you. Loved your hodl charts, they were very helpful when I was hodling.
What happened to hodl was very divisive much like a certain ongoing political campain.

yeah that's the case 32 bit OS not processor.
wanna upgrade but i don't wanna lose all my sh*t

eh, I try not to get involved in the politics (both in and out of the cryptosphere). I abstained from casting any vote on the HODL network change, but will certainly do my best to keep supporting services in compliance with whatever new requirements are. If a decision is unfavorable, but pushes the boundaries of current crypto technology, I see it as ultimately being a step forward (perhaps not for any one particular project, but for "crypto" in general).

Miner dev isn't my thing, but I can see how the recent HODL change could spur advances in miner options and development, just as the once-unique HODL feature of utilizing OP_CHECKLOCKTIMEVERIFY to create a TD system spurred my own creativity in advancing a more detailed block explorer.

make a backup of all your stuff to an external drive, or even get a new HDD entirely and install a fresh 64-bit OS. You can later cherry-pick "your sh*t" from the backup (or old HDD) for use with the new OS. A few extra steps, yes, but if it has been a long time since your last reformat/clean OS install...you're likely suffering from performance degradation and bloat anyways. I do a backup/wipe/fresh install of my computer every 1-2 years, you'd be surprised at how much useless junk gets left behind or missed from those supposed optimization programs.

That's an interesting perspective. I guess having a vested interest in the matter makes me more opinionated than I usually am.
Coin dev isn't my thing but I'd like the original hodl conecpt replicated with the ability to transact but not exchange locked up funds.
Kind of like a futures market.

32 bit support is requested by botnet guys in general Wink i suggest you dont waste you time with that :p will just create more antivirus definitions...

I hadn't considered the botnet angle, I thought Windows was more of a botnet magnet. The varying degrees of optimization
in cpuminer-opt makes it less attractive to botnets.

But yes it's also a waste of time and effort to support 32 bit. Most OSs no longer produce 32 bit builds so their days are
numbered.

ccminer is an exception because its often faster in x86, but cpuminer not at all

32 bit ccminer is faster on Windows, never tried it on Linux.

Which is funny, because they don't even do it properly - they just run the cpuminer 32-bit always. Slightly less brain-dead ones might deploy different ones to different machines - and if not under Win 10 (which is x64 only, right),  somebody with class might use Heaven's Gate to execute only the hash in 64-bit mode, and the rest being 32-bit (dynamic dispatching to either 32-bit or 64-bit as necessary, except in the case of Win 10 bots, which would be x64.)

EDIT: Oops, that *may* need care on Win 8.1 Update 3, either. Dat runtime detection.

Hi, All!

Is there any profitability calculator like whattomine.com but for CPU? Plenty of algos is here, 30 GPU miners are waiting to load their CPUs ;-)

You can use the performance comparison chart in the OP to get a rough idea of the relative algo performance but it varies on
different CPUs. It's best to use your actual hashrates at whattomine.

I have further investigated the issues with the blake algos.

Decred never worked on Nicehash with cpuminer, but does work on zpool. This is a pool issue. I don't know
which pool is correct and I don't really care because I don't know how to fix it for Nicehash. Also as previously
mentioned the performance of most of the blake algos is pathetic on a CPU. I won't be spending any more
effort on this issue.

Blakecoin and vanilla both seem functional to the extent I could test them but they are also underperformers
and not deserving of any attention.

I will attempt to maintain the status quo but I don't see any potential of useful CPU mining of these algos.

TROUBLE COMPILING CPU-OPT IN LINUX--

My mining rigs are 64-bit Linux, Lubuntu 14.04.4, and they are popoulated with both nVidia and AMD cards.  I compile ccminer, cpuminer-multi, and Genoil's miner on them, depending on the rig.  I have not been able to compile CPU-OPT on them, however.  If you have any general tips for Linux, please let me know, other wise I'll have to detail the errors and such.

I hope that you have the time to discuss this.  My CPU miners are earning over a dollar a day mining Lyra2re while my mining rigs mine with GPUs.       --scryptr

No compile problems reported for a long time so I need more info.

Have you ever compiled cpiminer-opt anywhere? On that CPU? With That OS? If so what version and how?
What is your CPU? And, of course commands and compile errors.
