- Does not work on 32-bit (though that’s not a problem with the algorithm).
- Patch is against older SVN. There’s a git repo at http://github.com/tcatm/bitcoin-cruncher
- Compiles on every 64bit Linux.
It’s not intended as a replacement for a standard client but for a dedicated bitcoinminer box. I’m planning a pluggable bitcoinminer someday. But at current difficulty it’s easier to work for bitcoins than finding faster ways for mining.
