Maybe just make a change in Makefile to use installed/preferred version instead of specified in the file - change the lines 43 to:

CUDA       = /usr/local/cuda
CXXCUDA    = /usr/bin/g++

how do you know the address of that wallet without downloading all bitcoin core ?
  

You do not need to download anything to check addresses, you may just open filen in Bitcoin Core and then you should see addresses and transactions.
In fact, you may even see addresses if you open .dat file in text editor and look for phrase 'name', which should be followed by an address (but it is very simple and not really trustworthy method).
In fact, you should use Bitcoin Core and then in the console use command 'dumpprivkey' to see if you have private key for the given address and if you may spend the balance.

If you need a fast way to check all the addresses, just copy/paste them into a new Electrum "watching-only" wallet ("File" -> "New/Restore" -> "Import Bitcoin addresses or private keys")... it'll find any/all transactions relating to those addresses and you'll be able to see which ones still have a balance.

NOTE:
- don't try and use the 6 word passphrases, that won't work in Electrum... just copy/paste the addresses. At least that way you'll see whether or not there is actually anything to find Tongue


I'm not aware of ANY wallets that used a 6 word passphrase... and because these 6 word phrases seem to be attached to one specific address, I don't think they are a true "seed mnemonic" for an HD/BIP39 wallet, but as mentioned earlier... I'd think they were some sort of "brain wallet"... or maybe some other custom system used to create private keys from words???


Given that the address from your screenshot: 1A9Tp3JjDvyQUtyQYLdDdCqMgK12sVZ238 is empty and has never actually been used, would you be willing to provide the 6 word passphrase for this address so people could try and figure out the system used? Huh or is it the same passphrase for ALL the addresses? Huh

and the 12 seed not working in elctrum
it give me wrong address  like this one
bc1qc4fdk5re3r08msaelnndnywnh9pec5p5tqh9kv

You must change the type of address to 'legacy', not segwit.

the address have .1 btc but in electrum have zero ?

If you use this seed on iancoleman page, do you receive in the table below your expected address and address from electrum?

The expected number of operation is the average number of group operations needed to solve the key (including the DP overhead). It correspond to ~50% probability.
If you use -m 3 and if the search is aborted, you are sure at ~99.7% that the key is not in the given range.


Thank you, now it is clear.
1847  Bitcoin / Bitcoin Technical Support / Re: hello every one i need help with old passphrase on: August 11, 2020, 04:36:22 PM

i find all the files in old hard disk
i foind many many addess of btc from 2014
and i found like more than 100 6 word called Passphrase
i found like more than 50 6 word called frases
i found 12 word called seeds

and many many many of adult vedio and pic

are you ok know Smiley

Then maybe start with what is called 'seeds' and see if it makes any sense. 12 words seeds look better than '6 word passphrase'.
"6 word called frases" sounds like a source for brainwallet.
1848  Bitcoin / Bitcoin Technical Support / Re: hello every one i need help with old passphrase on: August 11, 2020, 03:59:44 PM
Then I would try to use the page I mentioned and see if any combination of bip version gives the expected address.

Maybe try download old version of Electrum, released before 2014?
From the official site electrum.org or maybe git (but I am not sure about it).

i wont send any list  but i will give who help me 10% of what i find in all wallet

So the best would be check manually one by one... quite boring but with 100 addresses it will take around 10 minutes, maybe 15...

If addresses are old, then probably you have also some other 'coins', check here:

will take time for me to check all the address from the seeds ?

Depends on method ;-)

Send me the list of addresses or publish here, we will try to get the balances quickly.
1851  Bitcoin / Bitcoin Technical Support / Re: hello every one i need help with old passphrase on: August 11, 2020, 03:13:33 PM

do you know any way that i can check balance of many btc address ? like 10 address not like blockchain explorer check only one address in time  ?



You may try to use blockchain api and pass several addresses separated by comma ',' -> you will receive sum of balances:

https://blockchain.info/q/addressbalance/18zXdRJiosTZZ3cmUG8fjMewwpYG1FuDww,1F1tAaz5x1HUXrCNLbtMDqcw6o5GNn4xqX,33wvNiUkXJAJ85e4yXJxJVWtsKqWDsDFK4

You may also download list of all addresses with balance and check manually on your computer:

no i get different address  ?

But what about https://iancoleman.io/bip39/ ?
If you type your words into 'BIP39 Mnemonic' field, do you receive any result or message 'invalid mnemonic'?

i get many address with privatekey  start with litter L and K  but how to find what adrress  that have bitcoin ?

You should see address and the corresponding key... https://ibb.co/C1hp9Bg
If you see addresses, it means your words are correct. Does any of addresses (maybe in different tab) looks like one in the file?


yes it look like that

https://ibb.co/W6pbnfT

OK, but do you see any of your addresses?
In tab BIP32 or BIP44? With and without "Use hardened addresses" checkbox?
There is also a chance that your addresses are not compressed, this is something else. But first check existing possibilities.

 i did not find the address ans some i have only 6 seeds with no address


I do not know... If you have any seed & address without balance, maybe just publish here the seed, and then we will try to find the way to get the address, then you will be able to use the method for the rest of seeds.
All above is a bit chaotic.

Are your words on the list or there are others?

some word is not in the list ?


If you confirm that words are not from the list, that it is more complicated.
What you may try, is to use is to generate 'brainwallet':
https://brainwalletx.github.io/
If you use your sentence on this page, do you receive expected address (in compressed or uncompressed mode)?
1857  Bitcoin / Bitcoin Technical Support / Re: hello every one i need help with old passphrase on: August 11, 2020, 12:15:04 PM

ii search the net to find what kind of wallet use 6 seeds for bitcoin but did not get any answer coz my English and experience in  crypto is almost zero

it look like this

https://ibb.co/nw0q1xd

The point is that we also do not know ;-)
There are 2 possibilities:
1) What is called 'passphrase' is a 6 words seed - it is possible, but you must verify it yourself; I told you how to do it - You will have to convert it to format 'importable' by current wallets.
2) "Passphrase" is a sentence used to generate 'brainwallet' - which means that it could be any words, any sentence -> and it is converted into private key.

What you were asked before is to check what are the 'words' in passphrase - is it a sentence in English, or just a 6 words? Someone mentioned a list of allowed words:
https://github.com/bitcoin/bips/blob/master/bip-0039/english.txt
Are your words on the list or there are others?

this is the address and it have 6 word passphrase

its on pdf by the way 
may any one can help me collect that please 

Go to iamcoleman site
Enter your 6 words in  "BIP39 Mnemonic" field
Check tabs below, in one of them there should be your address, probably bip32.
If you find corresponding address, you may use value from column 'private key" to import into Electrum wallet, or any other software. Or even into blockchain.info web wallet (but do not do it).

Check this page: https://iancoleman.io/bip39/

For security you may try online or...
Wrong piece of advice. OP should use the tool offline if they are security conscious.

Yes... Autocorrect on the phone... I fixed it.

Check this page: https://iancoleman.io/bip39/

For security you may try offline or download sources from git.

On the page you may convert your seed to private key, and then you should be able to import it to any client (like electrum, etc)
