An (even more) optimized version of cpuminer (pooler's cpuminer, CPU-only)

[bitcoinraffle.co]

Not sure what you mean by "using" macports.  I just installed it, but it still didn't work.  Do I need to build minerd from source?

I was just wondering if you had it installed.  If not, and it threw that error, it might be a misconfiguration on my part.

Not really sure though.

I'm getting this error on OS X:

dyld: Library not loaded: /opt/local/lib/libidn.11.dylib
  Referenced from: /Users/longdongsilver/./minerd
  Reason: image not found
Trace/BPT trap: 5

Stupid question: did you try installing libidn via macports?
Also, what version of OS X are you running?

[bitcoinraffle.co]

I did that, but then I get:

dyld: Library not loaded: /opt/local/lib/libssl.1.0.0.dylib

I'm running 10.7.4

Now, let me try to make a list of the various errors that have been reported.

Code:

HTTP request failed: The requested URL returned error: 503

I tried mining at MaxBTC for a couple hours, but I was unable to reproduce the problem. I'll keep trying.

This one seems to be pool specific and is very rare. Let's ignore it.

Code:

HTTP request failed: Recv failure: Connection reset by peer

If we are to believe libcurl, this means that the connection was closed by the remote server.
I don't think there's much the miner can do to avoid the error, apart from silently ignoring it. Maybe I should consider doing that for the long polling connection?

Solved by setting the timeout (-T) to a value smaller 160s.

Code:

HTTP request failed: necessary data rewind wasn't possible

Under "normal" conditions, data rewind shouldn't be needed: it is usually only necessary for resuming interrupted uploads or for multi-pass authentication.
I suppose the "Operation timed out after 30001 milliseconds with 0 bytes received" error is linked to this.
Implementing data rewind is pretty simple in our case, and cannot do any harm, so I will try to implement it and see if anything changes.

Solved by your patch.

Thank you very much, pooler!

It's working like a champ now.  I had to reinstall libidn and curl using macports. 

Thanks guys.

I did that, but then I get:

dyld: Library not loaded: /opt/local/lib/libssl.1.0.0.dylib

I'm running 10.7.4

Awesome, thanks for the info.  I've updated the readme to reflect those dependancies in the zip file.

I'm not sure what this means and how to fix this easily.Can this app be made with a gui? As I really struggle with terminal.Maybe someone or pooler can make a quick gui that I can use to just start/stop and add pool/login info.Thanks

I'm running OSX 10.6.8 on my MBP and can a gui be made for windows as well please?

If I remember correctly, the OS X binary available at GitHub was compiled on OS X 10.7, so this is probably just a version compatibility problem.

A portable GUI already exists.

Linux and Windows binaries are available, and I'm sure it can also be compiled for OS X.

Alternatively, the Litecoin QT client has a mining page you can use to pool mine. Just put the cpuminer executable (minerd) in the same directory as litecoin-qt.

Most likely it's what pooler said.  I compiled it on osx 10.7.4, with updated versions of any dependancies and a couple seat-of-the-pants fixes.  You can try to upgrade libcurl yourself using macports, though I have no idea how risky it is with anything other than what I'm using.

I tried updating the libraries with macports,made no difference still the same error.I did download the copy that installs on snow leopard.Maybe its time to upgrade to lion when all my stuff compatible with it (special fx software,etc).Also pooler where is the directory on a mac for the litecoin-QT as I couldn't find it in the applications itself.I revealed package contents to find it,copied the miner and still no avail from the LTC client so I moved to 3rd party miners thinking they're better.

[Phraust]

try installing libcurl with "sudo port install libcurl +universal"

THat one worked for me.

I'd be happy to support this Fanquake. Once I get more BTC,I'll consider tipping you.

I've just built it, so I'll put up a download link shortly.

Thanks.This is great news Fanquake

anything? Like to get this going.

All I did was, backed up my OS as an image, secured erased my SSD, restored the OS image back to my SSD.

Man, pooler, thanks.
