Title: consequences of --with-incompatible-bdb ? Post by: pysiak on November 11, 2013, 07:33:38 PM I'm building my bitcoind on debian 7.2 which provides libdb++-dev in 5.1 and this forces me to use --with-incomaptible-bdb.
It works, but what are the risks of running non 4.8? Is it only for portability of the data between installations using different version of the library? Title: Re: consequences of --with-incompatible-bdb ? Post by: faceface on August 23, 2019, 10:29:02 AM Same question... 6 years later.
Title: Re: consequences of --with-incompatible-bdb ? Post by: danda on August 23, 2019, 08:34:57 PM as I recall, the blockchain database uses leveldb, but the wallet uses bdb. So if you build with a different bdb version and then create and uses a wallet with that version, then your wallet cannot be opened with a standard ( bdb v4.8 ) version of bitcoin-core. This could be an issue for you years down the road, when maybe you are trying to restore the wallet on some other computer/os.

There was an old thread (2014 or 15 perhaps) where someone was making an alt-coin that did this. You would have to go digging in the altcoin sections to even have a possibility of finding it. It's just something I vaguely remember from years ago. Sorry I could not be more help. -Dave Title: Re: consequences of --with-incompatible-bdb ?

This could be an issue for you years down the road, when maybe you are trying to restore the wallet on some other computer/os. Wallets created with different (I used v0.7 and v0.14) versions of the precompiled binaries in Windows can be used with Bitcoin Core made with --with-incompatible-bdb in Ubuntu 14.04, 16.04 and 18.04. At least I didn't encounter any obvious problem. But it's potential incompatibility, risk that some wallet functions may not work. And risk that a wallet can't be opened with future versions. |
