I hate when I do stuff like that. I left off a critical three letters. Memory is not so good when it's late.

I built pooler's code on my PowerMac G5 (PowerMac9,1 ppc970fx, 1.8 GHz) running Ubuntu 11.10 and achieved ~1.45 kH/s. ssvb's code on the same machine provides ~3.10-3.25 kH/s.
I used CFLAGS="-O3 -mcpu=G5 -mtune=G5 -maltivec -fstrict-alias" when I built both.

Cool, I didn't know about the -mtune flag, thanks. Still, I have to keep OSX on my machines, so compiling is... challenging.

I got pooler's code to compile for PPC OSX as well (he made the code work for big endian systems now, thanks pooler!), but it fails on some systems I tested on. I'm going to recompile on Monday with a different machine and see how it goes. If I get a good binary, I'll post that as well.
ssvb's code would likely work better for PPC, but I'm having more serious problems compiling it. There are missing header files, etc. I'm sure it's because OSX 10.4 is so old. (I don't have any machines running 10.5, so I haven't tested ssvb's code there)
Anyway, I'll post a PPC binary if I can get it to work well. If I ever get ssvb's code to compile, I'll post that as well.

Is it possible to compile it under ubuntu 10.04? I am getting the following error.
./configure: line 5013: syntax error near unexpected token `,'
./configure: line 5013: `LIBCURL_CHECK_CONFIG(, 7.10.1, ,'
I have the previous version running without issues on the system getting this error.
Thank you!

You need libcurl and libcurl-dev. Run automake again, then configure.
Edit: You'll have to undo what automake did. It seems like there's a command, but I forgot it, so I just deleted the directory and unzipped it again.
Problem Solved
1) sudo apt-get install libcurl4-openssl-dev
2) delete directory
3) unzip
4) build
5) Working!!!! TY!

No. I don't really understand what you want me to do. I think I'll have to stay with the christmas binary.

Hi!
I just tried to build this form github on OsX 10.7.2 and got an error at ./configure :
checking pkg-config is at least version 0.9.0... yes
./configure: line 5107: syntax error near unexpected token `,'
./configure: line 5107: `LIBCURL_CHECK_CONFIG(, 7.10.1, ,'
I don't know if it's just my system as i quite often fail to build something from source

Hm I got ./configure to finish normally after removing everything from macports and installing fink and libcurl via fink.
Now i'm getting these errors from make:

A quick update w/ the newer binaries for windows 64bit.
I tested them on a BD FX4100 @ stock speeds and it now gets 4.55kh/s / thread.
Quite an improvement! =)
Before, I got maybe 2.3kh/s / thread.
Same impressive increase for me: with the version published around December 20 I got like 3.6-3.8kh/s, now I'm at 5.0-5.1kh/s, on a P2X4 955 @ 3.6GHz (all that being per thread, of course). Going to try that on my Linux C2D E6550 ASAP...I tested them on a BD FX4100 @ stock speeds and it now gets 4.55kh/s / thread.
Quite an improvement! =)
Before, I got maybe 2.3kh/s / thread.
Edit: no improvement for the C2DE6550. Well, this restored the AMD/Intel balance then

These machines are on anyway, and the added power draw is on the order of 40W per CPU, depending on CPU (laptop is substantially less, main rig a tad more). That doesnt cost me $12 per month, but thats for everyone to calculate.

Yes, I have considered this, but haven't messed with it just yet. I drop the priority for the dedicated cores I put to it, but haven't messed with running both a GPU and a CPU associated with the same core with the minerd at lower priority.
It works just fine. No need to mess with assigning cores to threads. There is no bitcoin mining performance impact on my rigs from running litecoin miner.

I may fiddle with it eventually, but it's only 6 cores that I have right now. Not too much I'm leaving on the table given CPU chain value ATM.
No fortunes no, but I mine about 1000 LTC per month with 2 rigs. For now at least, thats a bitcoin or two. Still nice.

On the windows version, I get ~11.34 kh/s per core on a 2600K @ 4.5GHz, or a total of 45.36 kh/s
Pretty fast!
