Building from source with custom command names

Question

Is it possible to compile and build the three files (multichaind, multichain-util and multichain-cli) with custom command names? for example: name the files blockchaind, blockchain-util and blockchain-cli and use blockchain-util create chain1 to create chain1?

Answer 1

[This answer is wrong but left here because of the subsequent discussion – please see other answer.] You can just rename the executables after they are built, and they will work fine.

I tried renaming the release version and it did not work (I could create a blockchain but could't run it).Will it work if I rename after building from source?

Please post a transcript of how you renamed the executables, what you ran, and the error messages you saw - because this surprises us.

I renamed the files as following:
multichaind -> alphachaind
multichain-util -> alphachain-util
multichain-cli -> alphachain-cli

Then I ran "alphachain-util create chain1" and the response is
MultiChain utilities build 1.0 beta 2 protocol 10008

Usage:
  multichain-util create <blockchain-name>  ( <protocol-version> = 10008 ) [options]        Creates new multichain configuration file /home/ubuntu/.multichain/<blockchain-name>/params.dat with default parameters
  multichain-util clone <old-blockchain-name> <new-blockchain-name> [options]               Creates new multichain configuration file /home/ubuntu/.multichain/<new-blockchain-name>/params.dat copying parameters
                                                                                            from /home/ubuntu/.multichain/<old-blockchain-name>/params.dat

Options:
  -datadir=<dir>                              Specify data directory
  -<parameter-name>=<parameter-value>         Specify blockchain parameter value, e.g. -anyone-can-connect=true

And there is no ".multichain" folder or any file related to multichain. And there are no background processes either.

Whereas when I run it normally without renaming, I get
MultiChain utilities build 1.0 beta 2 protocol 10008

Blockchain parameter set was successfully generated.
You can edit it in /home/ubuntu/.multichain/chain1/params.dat before running multichaind for the first time.

To generate blockchain please run "multichaind chain1 -daemon".

Answer 2

My mistake – the other answer was wrong. It's actually not possible to rename the binaries right now because there are hard-coded checks inside the code. You can fix this by removing the checks from line 124 of utilwrapper.cpp and compiling yourself, or else wait for version 1.0.1.
