Generic genesis block miner | Bitcointalksearch.org

Hi, I'm trying to create the genesis block for an altcoin that has a different hashing algorithm (can't use GenesisH0). I found a snippet (see below) and tested it on the litecoin code, but it doesn't work, the hashes are wrong and the litecoind crashes with a segfault. And if I try with -reindex, I get a

Code:

AcceptBlock: high-hash, proof of work failed

Is there a better generic solution that works for any altcoin no matter what hashing algo it uses? Preferably something like that gist I pasted, that can be done within chainparams.cpp. Thanks.

        * Put this before "consensus.hashGenesisBlock = genesis.GetHash();"
