Have compiled the client successfully, but can't get it to run. It seems to be wanting to use the home directory for the current user (which actually does not exist, on purpose) rather than the correct path specified on the commandline via -datadir=xxx

This is the 25th altcoin client I have compiled in recent weeks, have not seen this problem before. Any ideas?

Code:
$ /nas01/coins/joulecoin/joulecoind -datadir=/nas01/coins/joulecoin/ -proxy=xxx.xxx.xxx.xxx:1080 -maxconnections=16 -noirc
terminate called after throwing an instance of 'boost::filesystem::filesystem_error'
  what():  boost::filesystem::create_directories: Permission denied: "/nonexistent"
Abort trap (core dumped)

edit: this seems to be the section of code that is causing the issue. For some reason the "-datadir" arg doesn't seem to be recognised, so the path is set to the default (which under *nix is the home dir)

Code:
    if (mapArgs.count("-datadir")) {
        path = fs::system_complete(mapArgs["-datadir"]);
        if (!fs::is_directory(path)) {
            path = "";
            return path;
        }
    } else {
        path = GetDefaultDataDir();
    }
Shot in the dark, probably won't help:
Try -datadir=.

Your github README still links to the Zetacoin thread...

What does this coin do differently?

Joulecoin generates the bulk of its coins over a much longer period than Zetacoin, more similar to Bitcoin and Litecoin. Reward halving occurs every 2 years and only ~45 million coins will be mined. It also retargets difficulty on every block.

Thanks, Readme file updated to point to this forum.

Difficulty retargets every block (exponentially) based on last 160 blocks

Can you explain this retarget?
Thanks
I'd imagine it's like this:
Block 1 took 2 seconds to find
Block 2 took 3 seconds to find
Block 3 took 4 seconds to find
Total: 9 seconds/3 blocks = average of 3 seconds. Retarget would be based on that (with 160 blocks instead of 3, obviously)

Current diff update: 36

Independent by the network haspower???
So diff can only growth???
No....
The block target is 45 seconds. If they average is below 45 seconds, the difficulty will rise. If it is above 45 seconds, it will go lower. Right now, it is very fast, so it will rise until the time between finding blocks is 45 seconds.

my pool doesn't seem to be updating with my hashrate and shares. still says I'm at 0 mhashes, and I've already have shares + invalid shares

it takes average hashrate in last 10 minutes and cron is running every minute... all stats are slightly delayed

Hashing away.
EDIT: Everything seems good. Climb aboard, miners.
EDIT2: Difficulty finally ramping up, pool is now a decent idea.

Lot of orphan  Tongue
Yes. When it's at difficulty 1, there seems to be mostly orphans. When it switches any higher, much less orphans.

Doesn't seem to be up yet. Not that it's needed at 1 difficulty currently. I might get a P2P pool set up later on, too.

If my maths are right, rewards drop at block 700800, might be a while. Smiley
