Monero: Solo mining error or generated a bad new genesis tx

[loldlm1]

I did a Monero fork and i added to it a code to generate for me a new genesis tx with the knowed command --print-genesis-tx and it works great at start, it generates something like this 013c01ff000180cab5ee01029b2e4c0281c0b02e7c53291a94d1d0cbff8883f8024f5142ee494ffbbd08807121015b6c9c53d57e60a1283edfba1d2a6510c922f351d86c7f537de64082fdb76110 but if a try to do a solo mining i get this:

strat_mining <address>

I want to premine my own cryptocurrency so the first block is 0 and the next is the max amount. But i think it isn't the problem, I think the problem is the genesis that i create.

Run with log level 1, it'll tell you what is wrong. This is not a support channel, however, so futher questions of this type will be ignored. Try #monero or reddit, which are for user type questions.

Sorry i was a little tired with this problemas, i already fixed it disabling this

your_coin/CMakeLists.txt:102 # set this to 0 if per-block checkpoint needs to be disabled set(PER_BLOCK_CHECKPOINT 0)

loldlm1 can you share with me the code you used to generate the genesis-tx

@3ch0elite did you manage to print or generate the genesis-tx?
