Does someone know what is that error? i cant compile :/

EDIT: i installed opencl-headers that seems i needed. now i have another problem, posting photo
EDIT2: solved the other problem. Now i dont understand what i see:

It looks like you're using Linux yes?  If so, here's a simple guide of how to get it working provided by user nonnakip:

I spend several hours getting oclvanitygen working with AMD Radeon 7xxx on 64-bit Linux - Ubuntu 12.04 and Ubuntu 14.04. In the end only the following is needed:

  • Ubuntu drivers
  • vanitygen patch
  • 1 userspace library file from AMD APP SDK v2.7

I created a minimal instruction text file. Maybe this will save someone some hours of searching the internet.

You should add a note to remove *.oclbin, since ppl with problems already have a compiled OpenCL binary and it wont be regenerated unless the file is missing.

First: I'm very sorry for my English! Second: Sorry if I post my question in a wrong place.

I have a Piperwallet and I want to add into it the code to generate "Choco-paper wallets". I meant paperwallets for the chococoin altcoin.

I know that I have to handle the code of the vanitygen's commands to adjust the properly generations of the privkey and pubkey of the chococoin.
I looked for some examples and I understood all of them. But when I try to do the same with the chococoin something goes wrong. 

If I do a Pub/Priv address generation for Dogecoin:

Code:
./vanitygen -X 30 D

and I get valid Pub/Priv addresses:

Privkey: 6JCejZtYD4PBququxsDG2BgQo1xLL1EvJa3sLDr8KE3TSLVoT5B

But if I try to do the same to generate a valid Pub/Priv couple of addresses for the chococoin it fail:

Code:
./vanitygen -X 16 7

Because the privkey of a chococoin address must begging with 8.

What is that I'm doing wrong?

Thank for any help.

The decimal code for an address that starts with 8 is 17, 18 or 19; not 16.

Check these out.

I meant the chococoin's privkey starts with "8" but the Address starts with "7"

This an example of what I expect for output from Vanitygen.

Are the privkey of said coin compressed or normal ones?

I did a check on the source of the generator @ chococoin(.)org and it seems this coin does not follow the vanitygen software.
When using the -X prefix the following settings are made active
Code:
case 'X':
addrtype = atoi(optarg);
privtype = 128 + addrtype;
scriptaddrtype = addrtype;
break;
The address type is set to 15 (0x0F) and the privtype to 143 (0x8F)
The source code has these numbers fixed at 15 (0x0F) and 224 (0xE0)
I added a test section in my code, change the following:


Code:
while ((opt = getopt(argc, argv, "CLvqnrik1eE:P:NTX:F:t:h?f:o:s:")) != -1) {
Add a option for C
The add add the following case with conditions
Code:
----.... snip ....----
case 'C':
addrtype = 15;
privtype = 224;
scriptaddrtype = 224; // I'm not sure what number this must be...
break;
and rebuild the project.

this is the result

It's is a correct pair ok keys!!!! It does works in the client chococoin-qt.

Just wanted to say thanks for this tool, it is very cool, and I was able to easily use it and get a vanity address.  Cheers!

Hi all!

vanitygen parameter "-F" in what format pubkey need?

"pubkey" is already the default.  The -F parameter would be used as following:
.exe -F pubkey 1...
.exe -F compressed 1...
.exe -F script 3...

Each bitcoin address is the result of an encoding of a hash the public key.  That public key can be expressed in two ways, uncompressed (equivalent to X and Y coordinates) and compressed (equivalent to X coordinate and a sign, from which the Y coordinate can be derived).
Say you generate '1abc' using both (don't actually use these keys/addresses!):
Uncompressed (default):
Code:
vanitygen.exe -F pubkey 1abc
Difficulty: 4553521
Pattern: 1abc
Address: 1abcCjhme96hnPDe3pDc3Ch1EnEj5Rjv7
Privkey: 5KG6rYdSopgYo1rejJAdPfbS6RgqhtAecg7EA19mJi9P9s2Ftru
The private key for an uncompressed form always starts with a 5.

Code:
vanitygen.exe -F compressed 1abc
Difficulty: 4553521
Pattern: 1abc
Address: 1abcRZRi2Gh4tZHJNbAyVyjSRx8uB67jk
Privkey: L2i2dzuR7CtDTkXQeh2m9jKiBtuxFNTTCHobBb3bySaHhxDFf6WK
The private key for a compressed form starts with a K or an L.

This is generally how wallet clients etc. recognize which form to use, and that's important because of what I mentioned earlier.  Let's say I use the private key 5KG6rY, once with the correct uncompressed public key, and once with an incorrectly assumed compressed public key:
Code:
private: 5KG6rYdSopgYo1rejJAdPfbS6RgqhtAecg7EA19mJi9P9s2Ftru
public key (uncompressed): 04C57E907AEC9BA14D377EA1627672197A87D38A0BB12A390B1504FF9A6A941772D052906B5A5AFB908E096C1C884C0E14096BB47EAC617C99DEDADBC4AE5241F7
hash: 065A9D7AD12CA8C1962FB0E21C4E92DB86BE137E
address: 1abcCjhme96hnPDe3pDc3Ch1EnEj5Rjv7

Code:
private: 5KG6rYdSopgYo1rejJAdPfbS6RgqhtAecg7EA19mJi9P9s2Ftru
public key (compressed): 03C57E907AEC9BA14D377EA1627672197A87D38A0BB12A390B1504FF9A6A941772
hash: D4BEAF01D5E007F63FB28BF262DF1E9E3A68132B
address: 1LPtgbhspbUKVxmntmRSYzUMkpkZiHJH6w

So you can see that if you make an incorrect assumption, you end up with the alternate (non-vanity) address.
( You'd probably be searching quite a while to find a private key that yields a vanity prefix in both uncompressed and compressed, let alone the same vanity prefix Smiley )

As a general rule, you should probably be using "-F compressed", as the blockchain ends up being smaller if everybody used compressed public keys (even if it does get negated by dust, comment spam, tumblers, etc.), but either pubkey or compressed will work.

The "script" one is a parameter you can ignore unless you really want to muck about with BIP13 type transactions Smiley

( Note that the above applies to Bitcoin addresses - if you're generating for an altcoin, the -F parameter may or may not apply depending on that coin's details. )

Hi all!

vanitygen parameter "-F" in what format pubkey need?

"pubkey" is already the default.  The -F parameter would be used as following:
.exe -F pubkey 1...
.exe -F compressed 1...
.exe -F script 3...

Each bitcoin address is the result of an encoding of a hash the public key.  That public key can be expressed in two ways, uncompressed (equivalent to X and Y coordinates) and compressed (equivalent to X coordinate and a sign, from which the Y coordinate can be derived).
Say you generate '1abc' using both (don't actually use these keys/addresses!):
Uncompressed (default):
Code:
vanitygen.exe -F pubkey 1abc
Difficulty: 4553521
Pattern: 1abc
Address: 1abcCjhme96hnPDe3pDc3Ch1EnEj5Rjv7
Privkey: 5KG6rYdSopgYo1rejJAdPfbS6RgqhtAecg7EA19mJi9P9s2Ftru
The private key for an uncompressed form always starts with a 5.

Code:
vanitygen.exe -F compressed 1abc
Difficulty: 4553521
Pattern: 1abc
Address: 1abcRZRi2Gh4tZHJNbAyVyjSRx8uB67jk

Good afternoon.
Thank you for an answer.
but I however to the end understood how to use pubkey.
here line with the key over brought by you.
