New demonstration CPU miner available

[xf2_org]

So there's no way to use cpuminer on OSX, then?  I was a little thrown off by the OSX build support message...

Remove yasm and everything works fine on OSX.

Running minerd on a server with 2 six-core opterons.

"minerd --url http://xxxxxxxxx.com:8332 --userpass xxxxxxxxxxxx -t 12 -a 4way -q"

I have 435 of these after running it for 20 hours
PROOF OF WORK RESULT: false (booooo)

And no "true"

Is this normal?

EDIT:
Here's what my speed looks like--

What is the network/pool target?

It's certainly very normal for the mainnet, with its huge difficulty.

It's certainly very normal for the mainnet, with its huge difficulty.

I'm running it solo pointing it to another server so I can improve the compilation and just test the overall feasibility of running this on several.

Hey,
im using minderd on my mac.... with the default algo i got 100%cpu usage as i aspected but when i change the algo to 4way (i think it should be faster or am i wrong?) i hav no cpu usage...
so whats the differecnce between the algos?

when i change the algo to 4way (i think it should be faster or am i wrong?)

You need to experiment, but on my father's MacBook, the default c implementation was the fastest by far.

Ubuntu 11.04 Natty AMD64 make problems

Code:

general-beck@gblive:/userdata/Bitcoin/cpuminer-1.0.1$ CFLAGS="-O3 -Wall -msse2" ./configure
...

I think the problem is that the first option in cflags should be 03 (with a zero) NOT O3 (with the letter 'o'). Hope that helps.

Nope, that should be -O3 (as in oh three). It's optimisation level three.

Is it possible to use this behind an HTTP or SOCKS proxy?

I am having troubles with ./configure detecting LIBCURL on Centos 5

Code:

Package curl-7.15.5-9.el5_6.2.x86_64 already installed and latest version

I noticed a previous reply saying that it's caused by ./autogen.sh's failure to detect it's location, but I've opened autogen.sh and cannot figure out what needs to be done.

Code:

$ CFLAGS="-O3 -Wall -msse2" ./configure

...
./configure: line 4598: syntax error near unexpected token `,'
./configure: line 4598: `LIBCURL_CHECK_CONFIG(, 7.10.1, ,'

Thanks in advance

Yes, this is a FAQ.  Use the tarball, not git repo, for building.

How do I disable SSE? Or is it supposed to work an Intel Mac?
I am trying to compile on a OSX,, and I get

The ugly fix is to hide yasm.  yasm produces something that the compiler does not like, on OSX.

I'm having problems getting the sse2_64 mode working on Ubuntu. I've read through this thread, and it seems that the major hangups are either having yasm < 1.01 or not actually being on a 64bit OS.

I've installed yasm 1.1 and confirmed that manually using 'yasm --version'. I've also confirmed that my architecture is 64bit using 'uname -m'.

When I run configure using 'CFLAGS="-O3 -Wall -msse2" ./configure' everything appears to go just fine. It detects the yasm version properly.

I am then able to run make, and everything appears to build correctly. Unfortunately, I don't seem to have the option to use the sse2_64 mode. Am I missing something? It even looks to me like it is linking the sse2_64 code into the binary. Here's the last line:

gcc -DHAS_YASM -O3 -Wall -msse2 -pthread  -o minerd cpu-miner.o util.o sha256_generic.o sha256_4way.o sha256_via.o sha256_cryptopp.o sha256_sse2_amd64.o -lcurl compat/jansson/libjansson.a -lpthread x86_64/libx8664.a

If you run:

Code:

minerd --help | grep sse2_64

Do you see any output? It seems to work for me on my 10.10.

Well, just because sha256_sse2_amd64.o is being linked in doesn't mean it will be available as an algorithm (it's basically a dummy object if it doesn't think it can be compiled). You could try adding "-DWANT_X8664_SSE2" to CFLAGS to see whether that helps/produces an error that will help you track this down.
Looking at miner.h, it seems like the only dependencies are a 64-bit environment, SSE2 and yasm, though, so you may want to double-check the output of configure...

Code:

F:\CPU-miner>minerd.exe --user djinfected --pass dji12406btio --url http://minin
g.bitcoin.cz/ --algo 4way
[2011-06-03 00:00:51] 1 miner threads started, using SHA256 '4way' algorithm.

[2011-06-03 00:00:53] json_rpc_call failed, retry after 30 seconds

I don't understand what this means. I get this with the default algo too.

It looks to me like you're getting an HTML response instead of a JSON one. Something to ask your pool admin about (or double-check the URL you're passing, especially if the pool doesn't use the standard port).

Hi,

I downloaded the 1.0 Windows binary installer.

No matter what options I set, it gives me the help message

Code:

PS C:\CPU-miner> .\minerd.exe --algo c  --url btcguild.com:8332 --userpass 123:456

Is this a bug?

Or did I miss something?

I added :8332 and it worked (and I changed my pw so that one I posted won't work)
