Even with RoadTrain version I get compiler error on ubuntu 13.x

I think at the Digitalis Server of Open Transactions. Unfortunately i never was able to install the client software. Even with help for weeks. There are problems of some kind i cant solve.
is there a market where groupcoins are traded?
Not that I'm aware of........yet.

I just recently started merged mining on bitparking so I had to get a groupcoin wallet, I did get the GUI version to compile. Although it seems that it was been switched to Qt4 instead of wxwidgets because that is what it linked against in the make file.
My question though is that the groupcoin wallet has downloaded all the blocks it says are on the chain but its still 44 hours behind.... so does this mean that a block hasnt been created for over 44 hours on the groupcoin chain?

A logo would be nice though....... 
I grabbed RoadTrain's version from github, it seems to be working fine for me so far...

Just in case you have GRP logo or icon, I'd be glad to update the repo.-MarkM-
Cause GRP with I0C logo looks a bit...

Fixed retarget issue, added a checkpoint and a couple of nodes.

What's going on here
Sorry for flogging a dead horse but not quite...
In the new fork, nTargetTimespan is global (i.e. will be multiplied by 14 every call, and eventually overflow). If the above snippet is original client, it is local and so will behave as expected.
Am guessing it is global now as was referenced in some other function/s, otherwise making it local would have been the better fix.
You might want to check if mutating the value on the fly will affect any other usages of it too.
I'm assuming we are both looking at the same code, branch i0coin-0.8.x was default in git? If not my humble apologies.
Forgot about it being global. I'll try to resync from scratch to check and update code if needed. Thanks. 
Actually, KrLos, if you read THIS VERY PAGE, you'll see that there is now an updated version (though experimental) with a more recent bitcoind/bitcoin-qt base.
And it seems to work well, though I'd appreciate some feedback After all I could move on to other merge mined coins to update their clients.
Had floating point exceptions when downloading full blockchain. Can't be bothered forking in github but here's a patch:

Do you have any logs?
Original version increases nTargetTimespan for every GetNextWorkRequired with block < 9500.
This is used in some modulo operations later which I'm guessing eventually result in a div 0 after it overflows.
Also, couldn't see where it would be set back to 1 day on block 9500, without restart?
It's exactly what my code does, the same code is used in old client.
Code:
unsigned int static GetNextWorkRequired(const CBlockIndex* pindexLast)
{
const int nSmoothBlock = 9500;
const int64 nTargetSpacing = 10 * 60;

Move wallet.dat?
How I can groupcoin wallet:
1) download Pankkake's ova-file.
2) import this file into VM,
3) start VM with login\pass groupcoin,
4) wait while groupcoind synchronized data (approximately 2 hours),
5) some intresting command (Pankkake gives me):
groupcoind help
groupcoind getinfo
groupcoind getnewaddress
groupcoind sendtoaddress
groupcoind listtransactions & etc.
Now I have groupcoin address - 2hh8R3QHsDmcsbAGZyVG49FGrERb1S78m4d
Question: how I can build GUI-wallet with my new groupcoin address? Example - bitcoin & others cryptomoney.
I see screenshot in this theme from RoadTrain, but I did not understand how to do it.
Explained to me please step by step.
