Title: TECH HELP - trying to build wallet on ubuntu
Post by: chinook on May 05, 2015, 01:35:11 PM
experienced in coins, but getting this one damn error.

Code:
crypto@crypto-Veriton-3900Pro:~/flkcoin/src$ ./flkcoind -testnet flkcoind: main.cpp:2809: bool InitBlockIndex(): Assertion `block.hashMerkleRoot == uint256("0x0")' failed. Aborted (core dumped)


anyone have any ideas?

im attempting to build a litecoin based wallet on ubuntu

and getting this error

Code:
crypto@crypto-Veriton-3900Pro:~/flkcoin/src$ ./flkcoind -testnet flkcoind: main.cpp:2809: bool InitBlockIndex(): Assertion `block.hashMerkleRoot == uint256("0x0")' failed. Aborted (core dumped)


anyone have any ideas?


at first i thought it was normal to get this error, to genereate a merkle hash, but it has not generated any debug.log file anywhere, new to linux, am i blind or is it hidden?
open the terminal type cd /home/yourname/.flkcoin
then type ls -l  to see if debug.log exist
sudo nano debug.log

Try deleting everything in the testnet3 folder and run again.

Well then, what happens if you remove
everything from /home/crypto/.flkcoin/ ?

Title: Re: TECH HELP - trying to build wallet on ubuntu

Hm. That error message says simply
that it can't open the database. But if there is
no database, then you shouldn't be getting that.

Maybe debug.log has some new info?

And I take it you have generated a new genesis
block succesfully by replacing the values from
the debug.log?

I think there might be something funny with the database
installation..

Searching this forum for your error "error Invalid argument (22)"
brings up few results but no conclusive fix.

For now, maybe you could try removing the db and
reinstalling..

Code:
sudo apt-get remove libdb5.1-dev libdb5.1++-dev
followed by

Code:
sudo update
sudo apt-get install libdb5.1-dev libdb5.1++-dev

then go to your coin src directory and

Code:
make -f makefile.unix clean

and rebuild

Code:
make -f makefile.unix USE_UPNP=-

I have no idea if that would work. If not, I guess
re-installing ubuntu might do the trick.

I forgot to put "apt-get" before "update"

Code:
sudo apt-get update 
apt-get upgrade -y 
apt-get dist-upgrade

then try again

Code:
sudo apt-get install libdb5.1-dev libdb5.1++-dev

yeh, but sudo before update and upgrade commands.

You need to acquaint yourself with linux a little bit
before taking on this kind of project.

Just off the top of my head:

Is it possible this coin daemon is incompatible with a later version of Berkeley database?

Perhaps, one needs to go in the opposite direction and install version 4.8?

Most coins, unless they are cloned off a very old code base, will at least give the option to use level db exclusively instead of Berkeley database.

I thought of downgrading too, but he said he was following Shakezula's
old tutorial, and libdb 5.1 is used there.

chinook, do you have the source for your coin on github?

Though github seems to be down atm  :P
