For i can see it seems a problem with the mgw47-mt thing

perhaps you'll have better luck with something like mgw49-mt-sd-1_55 or near offer. The resolution lies in the <coinname>.pro file, look for where BOOST_LIB_SUFFIX is bound and ensure the numbers match the versions of the installed mingw and boost packages. Cheers Graham

i have managed to set to work a version 8.7 or something like that, but i cant do it with the last version, stuck in the genesis block, i have generated some hash that dont throw the assert, but it seems they are not right because when i run ./litecoind sometimes gives an error that cant find the best block; or cant read the block (when this happens i reindex and dont throw any error but stay like running but do nothing) with this I try to generate the genesis block, but never do more than 1 iteration, and cant be rigth, it should take a while to find the nonce for(genesis.nNonce = 0; consensus.powLimit < genesis.GetHash() ; genesis.nNonce++){ }
the hash function pass the assert, but it gives me then some of the errors mentioned above

lol, glad to see people still interested in my "how-to" 4 years ago ![Grin](https://bitcointalk.org/Smileys/default/grin.gif) Oh yes, looks like a lot of fun! Trying this out now. Does the guide need to be updated? Who found they needed to do a bit of extra research? I'm finding I have to look elsewhere to change port numbers for a start... Thanks for the guide to making new altcoins ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif) Love it! I hope to learn quite a bit from tinkering with the source and creating a nothing coin.

Does there exist any new such thread, with current reality, how to create a coin? Or it`s the same?

it is a good start point, but if you are going to code with latest release, this guide is obsolote, lot of things have changed since it was created. So it needs to be updated, most of all, how to create the genesis block.

it is easier with older versions, the newest one have changed a little bit, and can be harder, good luck with that

lol, glad to see people still interested in my "how-to" 4 years ago ![Grin](https://bitcointalk.org/Smileys/default/grin.gif) Thanks a lot for the detailed guide. I was searching for this for many days. This was the closest to what I was trying to do. By the way, The code has changed a lot in the most recent version of bitcoin's repo. I was facing issues with OpenSSL headers when I tried to run the older version of the code. I managed to change the parameters in chainparams.cpp and get the new hashblock and merkle hash. But stuck at finding the checkpoint methods that you mentioned in the guide. Without updating those the core is trying to load the checkpoints from disk and ends up in segmentation fault. Any solution or direction I need to look into might help. Thanks a lot again. Here is my debug.log 2017-07-31 21:06:42 Bitcoin version v0.14.99.0-42307c4bf-dirty 2017-07-31 21:06:42 InitParameterInteraction: parameter interaction: -whitelistforcerelay=1 -> setting -whitelistrelay=1 2017-07-31 21:06:42 Assuming ancestors of block 0000000000000000003b9ce759c2a087d52abc4266f8f4ebd6d768b89defa50a have valid signatures. 2017-07-31 21:06:42 Using the 'standard' SHA256 implementation 2017-07-31 21:06:42 Using RdRand as an additional entropy source 2017-07-31 21:06:42 Default data directory /Users/username/Library/Application Support/Bitcoin 2017-07-31 21:06:42 Using data directory /Users/username/Library/Application Support/Bitcoin 2017-07-31 21:06:42 Using config file /Users/username/Library/Application Support/Bitcoin/bitcoin.conf 2017-07-31 21:06:42 Using at most 125 automatic connections (4864 file descriptors available) 2017-07-31 21:06:42 Using 16 MiB out of 32/2 requested for signature cache, able to store 524288 elements 2017-07-31 21:06:42 Using 16 MiB out of 32/2 requested for script execution cache, able to store 524288 elements 2017-07-31 21:06:42 Using 2 threads for script verification 2017-07-31 21:06:42 scheduler thread start 2017-07-31 21:06:42 HTTP: creating work queue of depth 16 2017-07-31 21:06:42 No rpcpassword set - using random cookie authentication 2017-07-31 21:06:42 Generated RPC authentication cookie /Users/username/Library/Application Support/Bitcoin/.cookie 2017-07-31 21:06:42 HTTP: starting 4 worker threads 2017-07-31 21:06:42 init message: Verifying wallet(s)... 2017-07-31 21:06:42 Using BerkeleyDB version Berkeley DB 4.8.30: (April 9, 2010) 2017-07-31 21:06:42 Using wallet wallet.dat 2017-07-31 21:06:42 CDBEnv::Open: LogDir=/Users/username/Library/Application Support/Bitcoin/database ErrorFile=/Users/username/Library/Application Support/Bitcoin/db.log 2017-07-31 21:06:42 Cache configuration: 2017-07-31 21:06:42 * Using 2.0MiB for block index database 2017-07-31 21:06:42 * Using 8.0MiB for chain state database 2017-07-31 21:06:42 * Using 440.0MiB for in-memory UTXO set (plus up to 286.1MiB of unused mempool space) 2017-07-31 21:06:42 init message: Loading block index... 2017-07-31 21:06:42 Opening LevelDB in /Users/username/Library/Application Support/Bitcoin/blocks/index 2017-07-31 21:06:42 Opened LevelDB successfully 2017-07-31 21:06:42 Using obfuscation key for /Users/username/Library/Application Support/Bitcoin/blocks/index: 0000000000000000 2017-07-31 21:06:42 Opening LevelDB in /Users/username/Library/Application Support/Bitcoin/chainstate 2017-07-31 21:06:42 Opened LevelDB successfully 2017-07-31 21:06:42 Using obfuscation key for /Users/username/Library/Application Support/Bitcoin/chainstate: 7bbd099730c6ddd0 2017-07-31 21:06:42 LoadBlockIndexDB: last block file = 0 2017-07-31 21:06:42 LoadBlockIndexDB: last block file info: CBlockFileInfo(blocks=0, size=0, heights=0...0, time=1970-01-01...1970-01-01) 2017-07-31 21:06:42 Checking all blk files are present... 2017-07-31 21:06:42 LoadBlockIndexDB: transaction index disabled 2017-07-31 21:06:42 Initializing databases... 2017-07-31 21:06:42 Pre-allocating up to position 0x1000000 in blk00000.dat 2017-07-31 21:06:42 init message: Verifying blocks... 2017-07-31 21:06:42 block index 208ms 2017-07-31 21:06:42 init message: Loading wallet... 2017-07-31 21:06:42 nFileVersion = 149900 2017-07-31 21:06:42 Keys: 2001 plaintext, 0 encrypted, 2001 w/ metadata, 2001 total 2017-07-31 21:06:42 wallet 127ms 2017-07-31 21:06:42 setKeyPool.size() = 1999 2017-07-31 21:06:42 mapWallet.size() = 0 2017-07-31 21:06:42 mapAddressBook.size() = 1 2017-07-31 21:06:42 ERROR: ReadBlockFromDisk: Errors in block header at CBlockDiskPos(nFile=0, nPos=8) 2017-07-31 21:06:42 *** Failed to read block 2017-07-31 21:06:42 Error: Error: A fatal internal error occurred, see debug.log for details
