Just some quick notes to help anyone trying to build from git on Fedora 19:

First you need an OpenSSL without ECC removed.

I've put up RPMs: https://people.xiph.org/~greg/openssl/fedora19/
(The i686 ones are untested, but should work)

These have the patch Warren did for F18, and are set as epoch 2 so the system shouldn't "upgrade" it out from under you to a new version without ECC.

If you did not install as a development-workstation you may need to yum groupinstall 'Development Tools'

Once you've installed that, yum install libdb4-cxx-devel libdb4-cxx libdb4 libdb-utils.x86_64 boost-devel gcc-c++

BDB_LIB_PATH='/usr/lib64/libdb4/' BDB_INCLUDE_PATH='/usr/include/libdb4' BOOST_LIB_SUFFIX='-mt' make -j4 -f makefile.unix bitcoind USE_UPNP=

Tada.

https://people.xiph.org/~greg/openssl/fedora19/

cd ~/Downloads
sudo yum install -y git krb5-devel zlib-devel; sudo rpm -i --replacefiles --nosignature openssl-1.0.1e-4.fc19.x86_64.rpm openssl-debuginfo-1.0.1e-4.fc19.x86_64.rpm openssl-devel-1.0.1e-4.fc19.x86_64.rpm openssl-libs-1.0.1e-4.fc19.x86_64.rpm openssl-static-1.0.1e-4.fc19.x86_64.rpm
sudo yum install -y libdb4-cxx-devel libdb4-cxx libdb4 libdb-utils.x86_64 boost-devel gcc-c++ qrencode-devel miniupnpc-devel libupnp-devel qconf qdevelop automake qt-creator boost-build ccache libdb-cxx-devel

cd ~
git clone https://github.com/sexcoin-project/sexcoin
cd ~/sexcoin/src
sudo yum groupinstall 'Development Tools' -y
make clean -f makefile.unix
BDB_LIB_PATH='/usr/lib64/libdb4/' BDB_INCLUDE_PATH='/usr/include/libdb4' BOOST_LIB_SUFFIX='-mt' make -j4 -f makefile.unix sexcoind USE_UPNP=
strip sexcoind
cd ..
make distclean
qmake-qt4
make
./sexcoin-qt

Works for me on lubuntu13.04 and Fedora19LXDE.

next *5 block: 84658

And first prediction comes true. Block 84658 is a superblock with 500 coins.

Great work getting that together!

If I ever find Chinsu....... Angry

(Well, in all fairness, I missed it too. Great catch hotcoldcoin! )
..and I thought we handled the rand() issues in 1998.

So adding randomizer to todo list.

Is there a list of all the sexcoin superblocks found so far?

You can manually verify here:

http://sexcoin.lavajumper.com:9950

Fair warning: it gets a little flaky sometimes, but its accurate.

I'll look at the database and see if I can pull that data directly.

Thanks! The explorer is alive and working OK today. And version 2 of the test script is now complete. No more lame php/perl/python/etc attempts, this time in c++ with the exact same boost random library as the coin source uses.

The results are looking good. Here is the list of superblocks up to block 100,000:

http://pastebin.com/itW7n0tN

So far all my checks against the explorer show this list is correct. But someone please double check.

So I dare to make predictions:

I gladly help out with pictures for the sexcoin site. I just need to know what is needed.

@lavajumper / wife

Well, i prefere to look at female butts so... (although i have some sissy stuff on my site).
May i suggest renderotica.com? There are some excellent male renders there Wink

When I'm in work mode I'll send screenshots of the site, and you can unleash those creative energies.

Thanks Lava , You made my day..

Are you still trying to compile on Fedora? Any feedback on it?
TIA

Sorry, I'm answering lately.
I have hardware-problems because of our summer-heat and I'm trying to recover my lost partition. I think, tomorrow I will compile on Fedora again.

@LittleDigger&lyno,
is it possible to integrate this great pic into the official website? Grin

No.. It is possible to ask lynos if he can make some custom graphics for the site, and we have.

And I hate to say it, but with all the messing around with p2pools the website is behind schedule. I'm feeling frazzled and am going to get some downtime..

But if it means lyno's work is featured on the site, thats not a bad thing.. I definately think it would give it some "wow" factor..

I did a quicky script to check what block heights are superblocks. My script might be bogus, I dunno. I can't load the block explorer to check.

Was block #45 the first *5 superblock, and block #2043 the first *50 superblock?

Here's the list up to block #100000 : http://pastebin.com/0qZnUCKC

Block 9,48, and 215 were the first 3 5x blocks...first block is block 0.

I am curious. Are you getting the exact same numbers when you run the script twice? across reboots? on different computers? a debug compile vs a release compile?

I did run multiple times to make sure it spit out the same results, but no reboots or different computers , etc

But looks like the results are bogus. So back to the drawing board. Is there a list of all the sexcoin superblocks found so far?

Doesn't the Mersenne Twister function use some randomizer besides the seed? Maybe a time component? Otherwise it would just be a function. Or did I miss something big?

I vaguely recall hearing something about better seeding in MT. But in this case, I think it's just using the seed given. Since all nodes have to get the same rand from the same seed.

main.cpp

Code:

int static generateMTRandom(int s, int range)
{
random::mt19937 gen(s);
    random::uniform_int_distribution<> dist(1, range);
    return dist(gen);
}

...

int64 static GetBlockValue(int nHeight, int64 nFees)
{
...
//superblock random reward
int rand = generateMTRandom(nHeight, 100000);
...

I did a quicky script to check what block heights are superblocks. My script might be bogus, I dunno. I can't load the block explorer to check.

Was block #45 the first *5 superblock, and block #2043 the first *50 superblock?
