I have the following problem - when I compile daemon based on fehcoin (with pszTimestamp, block.nTime etc. changes) and I run it, I get empty nNonce:

Code:

Loading block index...
CBlock(hash=c18a2e48349763b42b90ac00881abee846203b789a2d86aacb2cd2aa5161c66f, ver=1, hashPrevBlock=0000000000000000000000000000000000000000000000000000000000000000, hashMerkleRoot=25cc2e3283b86f225057d0eaa0eaa0003b891de79828f59bb4fc0b290ab897e2, nTime=1388419211, nBits=1f00ffff, nNonce=0, vtx=1, vchBlockSig=)
Coinbase(hash=25cc2e3283, nTime=1375995262, ver=1, vin.size=1, vout.size=1, nLockTime=0)
CTxIn(COutPoint(0000000000, 4294967295), coinbase 04ffff001d020f272957687920776f756c6420796f75206e65656420426974207768656e20796f7520686176652053776167)
CTxOut(empty)
vMerkleTree: 25cc2e3283
block.GetHash() == c18a2e48349763b42b90ac00881abee846203b789a2d86aacb2cd2aa5161c66f
block.hashMerkleRoot == 25cc2e3283b86f225057d0eaa0eaa0003b891de79828f59bb4fc0b290ab897e2
block.nTime = 1388419211
block.nNonce = 0

block.nNonce = 0 Why is this happening?

Do This Modification in the Code:

Hello,

You can use this Code to find Genesis Block for N-Scrypt, Insert it before ///debug print comment which would be near hashMerkleRoot and compile ^_^:

Code:

if (true &&block.GetHash() != hashGenesisBlock)
{
printf("Searching for genesis block...\n");
// This will figure out a valid hash and Nonce if you're
// creating a different genesis block:
uint256 hashTarget = CBigNum().SetCompact(block.nBits).getuint256();
uint256 thash;

unsigned long int scrypt_scratpad_size_current_block = ((1 << (GetNfactor(block.nTime) + 1)) * 128 ) + 63;
char scratchpad[scrypt_scratpad_size_current_block];

loop
{
// Generic scrypt
scrypt_N_1_1_256_sp_generic(BEGIN(block.nVersion), BEGIN(thash), scratchpad, GetNfactor(block.nTime));

if (thash <= hashTarget)
{
printf ("found it!\n");
break;
}
if ((block.nNonce & 0xFFF) == 0)
{
printf("nonce %08X: hash = %s (target = %s)\n", block.nNonce, thash.ToString().c_str(), hashTarget.ToString().c_str());
}
++block.nNonce;
if (block.nNonce == 0)
{
printf("NONCE WRAPPED, incrementing time\n");
++block.nTime;
}
}
}

thank
