How do you insta the cpu miner on linux 13.04 x64?
You could clone the source code of cpuminer from github.com/zccoin/cpuminer, but you have to do some modifications of nChainStartTime and GetNfactor.
We have the downlink of modified cpuminer version, and it will be updated to github soon.

about gpu miner... i receive first share ))) ...

saphire hd7850 1gb
Code:
zcc --scrypt -w 8 --shaders 1024 --lookup-gap 2 -s 5 --no-submit-stale -I 15 -d 1
seems need to play with parameters))

So you got 3.8K hashrate with one single hd7850 1gb. That's still very decent. Good for you.

original cpu miner


example zccoin.conf
Code:
rpcuser=123
rpcpassword=1234567890
server=1
rpcport=1234
rpcallowip=*
addnode=153.127.244.215

example start
Code:
minerd -a scrypt -o http://127.0.0.1:1234 -u 123 -p 1234567890

minerd -a scrypt -o http://127.0.0.1:1234 -u 123 -p 1234567890


be careful in my version of cpuminer you need put
Code:
-a scrypt
not -a scrypt-jane to start mining zcccoin...

can upload source on other filehosting?

source code info for those hackers:
int64 nChainStartTime = 1375817223
// zccoin: increasing Nfactor gradually
const unsigned char minNfactor = 12;
const unsigned char maxNfactor = 30;

unsigned char GetNfactor(int64 nTimestamp) {
    int l = 0;
    if (nTimestamp <= nChainStartTime)
        return minNfactor;
    int64 s = nTimestamp - nChainStartTime;
    while ((s >> 1) > 3) {
      l += 1;
      s >>= 1;
    }
    s &= 3;
    int n = (l * 170 + s * 25 - 2320) / 100;
    if (n < 0) n = 0;
    if (n > 255)
        printf( "GetNfactor(%lld) - something wrong(n == %d)\n", nTimestamp, n );
    unsigned char N = (unsigned char) n;
    //printf("GetNfactor: %d -> %d %d : %d / %d\n", nTimestamp - nChainStartTime, l, s, n, min(max(N, minNfactor), maxNfactor));

    return min(max(N, minNfactor), maxNfactor);

Make gpu miner
GPUminer for ZcCoin, but as I said this would not be faster than CPU. Just for your information:

what is nChainStartTime ?

    int l = 0;
    if (nTimestamp <= nChainStartTime)
        return minNfactor;
    int64 s = nTimestamp - nChainStartTime;
    while ((s >> 1) > 3) {
      l += 1;
