Hi,

I would like to know if there is query allowing at install Bitcoin Core with for example only the genesis block, its next three blocks and the last three blocks.

I know, one can use prune in order to have a minimum of 550 blocks corresponding to 550Mb. However, this feature was available since 2014-2015.

-prune= Reduce storage requirements by enabling pruning (deleting) of old blocks. This allows the pruneblockchain RPC to be called to delete specific blocks, and enables automatic pruning of old blocks if a target size in MiB is provided. This mode is incompatible with -txindex and -rescan. Warning: Reverting this setting requires re-downloading the entire blockchain. (default: 0 = disable pruning blocks, 1 = allow manual pruning via RPC, 550 = automatically prune block files to stay under the specified target size in MiB)

 

Hi all,

I'm trying to compile Bitcoin Core but I'm getting an error message.

After the following commands,

Code:

$./autogen.sh
$./configure
$sudo make 

I got the the following error message :

make: *** No targets specified and no makefile found.  Stop.

A Makefile.am exists in the main folder so I don't see where come from.

I tryied querying Bitcoin-cli (Bitcoin Core 24.0.1) in Ubuntu 20.04 WSL2 doing the following commands :

Code:

$ bitcoind -debug -daemon

Bitcoin Core starting

Code:

$bitcoin-cli -rpcuser=user -rpcpassword=pass -rpcport=19084

but for this last command I get the following error :

error: timeout on transient error: Could not connect to the server
127.0.0.1:19084

Make sure the bitcoind server is running and that you are
connecting to the correct RPC port.

My bitcoin.conf file parameters are :

Code:

rpcuser=user
rpcpassword=pass 
rpcallowip=127.0.0.1 
rpcport=19084
server=1

I then tried the following command in order to check if bitcoind still running in the background :

Code:

$ps -aux

but apparently bitcoind stopped running for an unknown reason.

Hi all,

I try to create an altcoin, and successfully recompiled the code.

However, I received an error when trying to make a regression test. I then look for the log file but apparently it was not generated.

Also, I'm looking for a guide to set up a debuging environment.
