transaction create and signing

[Nelzat]

Hi everyone

I am trying to run the code to create a transaction on Armory using a python script  found in
https://github.com/etotheipi/BitcoinArmory/blob/master/extras/createTxFromAddrList.py, instead of the GUI.

I am getting the following errors,

1.RuntimeError: Cannot start transaction without db env

2.Segmentation fault (core dumped)

3.TypeError: UnspentTxOut_getNumConfirm() takes exactly 2 arguments (1 given)


Has anybody encountered the same problem?

Please aid and thank you very much.

1. You have to initialize the DB before you query it

2. That's what will happen if you pass a null DB pointer

3. UnspentTxOut.getNumConfirm(blockNum)

Hi goatPig

Thanks

1.You have to initialize the DB before you query it, I am running the Armory GUI too, which means the DB is initialized already, at least that is what i think.
or is there another way to do it?

2. That's what will happen if you pass a null DB pointer

3. The UnspentTxOut.getNumConfirm is in the Coinselection.py and if i add,(blockNum), it is undefined. Its a variable from nowhere

1. These are different processes altogether. The DB exists as a shared library within each process address space. You have to init the DB properly in Python process you are running your script from. Probably something is going wrong at this line:

2. Not sure what you mean by repeating the sentence

3. I meant blockNum as in any block height as integer. You can't figure out the number of confirmations a transaction has without specifying from which block height. By default, you should use TheBDM.getTopBlockHeight():

Hi goatpig

Thanks a lot, you actually helped me to figure out the problem.
