oops, yeah that's what I mean, updated my original post. all it outputs is CPU hash, GPU hash, and delta. Shouldn't it output address and privkey just like vanitygen64.exe does?
Let me guess, you're using an ATI 7xxx card? Oclvanitygen seems to be broken with 7xxx cards, and it produces incorrect results. Workaround is to use the -S command, but your speeds will be much slower (1/4 to 1/3 of the speed).

Yeah, 7950 Sad

Even then, I have not been able to get it to work. I get the same issue with my 5830. I'm not too worried now that I know its a "known" issue.

its fun to dump hundreds of thousands of addresses to a text file and search for cool things.
IIRC, older cards can have this issue fixed by using an older driver/SDK. 7xxx cards require newer drivers/SDK, so we don't have this option.

Yup, running 12.6 here. Explains a bit. It's my work rig, so I'm not worried about downgrading right now.

Finally got around to giving it a try, you are correct the -S command fixed the issue while using my 7950 and just like you said, it was about 1/3 slower. Better then nothing I guess. Thanks!

Total noob question...sorry...

Is there a reason why a pattern can not use a lower case "L"?

I want to generate pattern 1Akula but get a message about it being an invalid character.

Some characters are not valid because they are easily mistaken for others. So "l" cannot be used as it conflicts with "1". See the wiki "address" page for a list of invalid chars.

OK...another noob question.

All the crypto math and logic is a bit confusing to me and I need to spend more time to understand it.  As I understand it from a layman's perspective, the generator gets a random number as a starting point and then increments that number and hashes it looking for the chosen pattern.  If I would start the generator, stop it, then restart again for the same pattern, will it use the same number to start with?  I want to run the vanity gen at night and want to make sure that I am not duplicating work that was already done when I restart it each night.

Thanks.

It doesn't remember position but doesn't need to. Any time you start you will be looking at fresh number space because the chances of repeating work are so very, very tiny. The chances of repeating work are the same as the chances of finding an existing key - which is the whole point.

So any time you restart you are never wasting search attempts. It all counts.

You need the openssl headers installed, depending on the distro it would normally be a package like "openssl-dev" or "libssl-dev"

Thanks... I'm on Ubuntu 12.04 LTS. I thought I had openssl installed, because if I typed "openssl version" there was an output...

anyway I also installed this libssl-dev (there was no package openssl-dev) and now I get a little different output...

any ideas..?

You also need the "libpcre3-dev" package, or some similar one (don't recall now). It isn't clear about this in the INSTALL help file but I guess the dev expects everyone has most of this already installed. These dev packages usually have the header file (*.h) so any time you see a message about missing h files it's usually some dev package missing.

btw for future reference, and any onlookers, if you get "something.h missing" type messages one way I use to find out what package is needed is to use the apt-cache command to locate one suitable.

eg. pcre.h seems to be missing

apt-cache search pcre

This looks at the packages available and lists ones containing pcre. By looking thru that list you can often figure out which one is needed. In this case you want something with lib, dev, and C since the program is written in C. Give it a try.

I'm using Linux for 5 / 6 years now, and everyday I learn something new. Smiley But compiling stuff from source was always a pain in the ass..

will definitely look at this thread the next time I play with ./configure, make, make install... Smiley
