Genesis Hash

[BadBunny]

I want to try to make an altcoin (not for distributing it) but i can't figure out where to put the genesis hash. For the fork i used librexcoin (https://github.com/librexcoin/librexcoin/blob/master/src/main.cpp).
Can someone help me? Thanks..

EDIT: This is the error

Code:

/LibrexCoind --testnet
LibrexCoind: main.cpp:2542: bool LoadBlockIndex(bool): Assertion `block.GetHash() == (!fTestNet ? hashGenesisBlock : hashGenesisBlockTestNet)' failed.
Aborted

Aborted

I know, that's what the second link is for 

[BadBunny]

but i have already changed the pszTimestamp , two times, same error. 

[BadBunny]

tried with different coin, same error. any help?

[iGotSpots]

Timestamp is not all you need to change in second link

[BadBunny]

nNonce and nTime, got it!

Problems solved, the error was i diden't deleted the old genesis/merkler hash when i run the first build 

Now i have to try without -testnet and understanding checkpoints.
