anyway to support sse2 on ubuntu ?

Do you mean 4way or sse2_64 algorithm?

sse2_64 requires yasm, and a 64-bit machine.

[Spoddy]

Thanks xf2_org, I'm now up to gcc 4.3.3

gcc -v

Is this still a gcc version issue? And what version have others managed to compile on?

Use a newer compiler.

Shouldn't the configure script be checking for that, then?

[Tarion]

Code:

root@vs1028:/home/tarion/apps/cpuminer# apt-cache show libcurl3
Package: libcurl3
Priority: optional
Section: libs
Installed-Size: 444
Maintainer: Domenico Andreoli <cavok@debian.org>
Architecture: i386
Source: curl
Version: 7.18.2-8lenny4

But configure gives me:

Code:

checking whether libcurl is usable... no
configure: error: Missing required libcurl >= 7.10.1

Any Idea what is wrong?

[Tarion]

Found it on another page in this thread:

sudo apt-get install libcurl4-openssl-dev

Works!

Hi, I like to give some news about the not oficial debian/ubuntu package of bitcoin-cpuminer:

* You can find the version 0.8.1 in ubuntu and debian, only in ubuntu (maverick, natty, oneiric) have SSE2_64 enable.
* If not exist any issue in the last version 1.0, i will create a package in a couple days.
* If possible this package get in the next ubuntu release, please check: https://bugs.launchpad.net/ubuntu/+bug/780258, give you comment's or any feedback.

* @jgarzik: In ubuntu revu get this comment
http://revu.ubuntuwire.com/p/bitcoin-cpuminer

@sikon: I’m not sure about the binary name "minerd". It sounds too generic, not specific to BitCoin. Could it be renamed?

what you think @jgarzik ?

@sikon: I’m not sure about the binary name "minerd". It sounds too generic, not specific to BitCoin. Could it be renamed?

A rename will only be considered if a conflict exists with an existing, real-world program.

Otherwise, you're already looking at a program that's seen six months of heavy use on Windows and Linux, using the "minerd" name.  A rename would create pointless churn, with zero value for existing cpuminer users.

I got Mach-O x86_64 SSE2 to work (Mac OS 10.6.7). Here's the list of everything I did:

1. I got the file libcurl.m4 from a curl source tarball and stuck it in an m4 directory.

2. I installed the gnulib byteswap module into the cpuminer directory and updated build scripts as necessary.

3. When configuring, I had to use both "-arch x86_64" in CFLAGS and the '--build=x86_64-apple-darwin10.7.0' flag, since it seems to detect that my kernel is 32 bit rather than that my processor is 64 bit.

4. To assemble sha256_xmm_amd64.asm, I set "-f macho64" in the Makefile (todo: integrate this into configure)

5. To fix the assembly failures, I applied the patch here: <https://gist.github.com/971291>.

It fixes the 32-bit offset by using another register to hold the current target, which is then used directly and updated as necessary. This adds one extra line of assembly (I'm not sufficiently familiar with x86_64 assembly to know whether or not it actually adds an extra _instruction_, but it probably does) to the main loop as well as a push and a pop to save and restore the values of the register I used (r8). The assembly already uses r10 without doing a save and restore, but I'm not sure how to check that r8 is unused, so this might be unnecessary. It also fixes a problem where my gcc apparently adds leading underscores to all of the names.

This is the least clean section because it probably breaks the build on Linux. Nobody said assembly was supposed to be portable...

[chromicant]

Sorry I've missed most of the recent discussion...busy with a new addition...

The r10 "trick" of letting it get clobbered requires you know something about the calling convention of the OS in use. The Linux SSE2 code for x86_64 will completely break on Windows, since there's a different set of registers saved between function calls. Depending on what OSX does with r8, you may be able to let it get clobbered, saving you a cycle or two.

I never really found any docs on how the calling convention works under Darwin/Mac OSX. I'm sure reading the GCC source code would enlighten someone. But I also like my sanity.

I have a bitcoind server running and accepting connections aswell (rpcallowip=*).

I have tried to run minerd connecting to my bitcoind server, but all I got is:

# ./minerd -c miner.cfg
[2011-05-14 20:24:41] 8 miner threads started, using SHA256 'sse2_64' algorithm.
[2011-05-14 20:33:41] PROOF OF WORK RESULT: false (booooo)
[2011-05-14 20:34:16] PROOF OF WORK RESULT: false (booooo)

Also, the hash meter on the other side (bitcoind) did not increase at all.
Shouldn't the bitcoind (server) hash meter increase aswell ?

Am I missing something ? Am I 'pooling' wrong ?
I'm running openSUSE 11.3, kernel 2.6.34.8-0.2, i7 930.

Thanks in advance.

Version 1.0.1 is released.

The only change is the addition of OSX build support.  FreeBSD is also reported to be working out of the box.

There is no Windows build for this release (no need).

[Amelios]

I'm still getting this when trying to compile 1.0.1 on OSX:

There is no alternative.  It does not work for cpuminer on OSX.

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