Title: bitcoind not working on SPARC (and PPC)
Post by: Darka on July 14, 2011, 09:07:23 PM

Hello all!

I build bitcoind from last stable source (0.3.24). But it's not work. After i try run bitcoind i get:

Code:

bitcoind: main.cpp:1546: bool LoadBlockIndex(bool): Assertion `block.hashMerkleRoot == uint256("0x4a5e1e4baab89f3a32518a88c31bc87f618f76673e2cc77ab2127b7afdeda33b")' failed.
Aborted

Does anybody has solution for this bug?

Sounds like an endianness bug.

Any idea how fix it on non x86 platforms?

had the same problem with powerpc, what worked for me was to accept it and switch to intel.

and it's not solution, it's dirty lifehack =)

Not a bug so much as a design decision. The Satoshi Bitcoin implementation does not work on big endian architectures and likely never will.

If you want to be a BE Bitcoiner, your best bet is to use one of the other implementations like BitCoinJ or BitCoinJS.

Does BitCoinJ ready for production use on pool servers? Or only way is use dedicated x86 server for bitcoind?

I'm not that sure the codes relies on LE that often. The serialization routines for integers, uint160, uint256, and the fact that pointers to those structures are passed directly to hashing routines, would need to be adapted. That does seem reasonable (though not high priority) to change, unless there is a ton i'm forgetting now.
