Thanks for the info .. I know mining with cpu is not good at all ... but what I am asking is how to set up ccminer for example to mine with gpu ... I understand is not profitable . But I am not looking to be profitable for the moment I am looking how to set up a miner to mine ifc with gpu.
Okay, this may give you some idea of the potential. Back in 2014, before moving to ASICs, I mined with 4 X R9 270X and 2 x R9 280X.
Here's the 270:
http://www.gpuscanner.com/amd-r9-270The mining hashrate of a single 270X GPU is roughly equivalent to a Gridseed 5 chip ASIC (but power consumption is 20+ times more!)
There are other GPUs listed on that site, so if you can find yours, scale the estimate based on the hashrate.
My 15-20% estimate in a previous message was a fair bit off. I've checked actual mining output and over the past 2880 blocks (24 hours) my Gridseed won 63 blocks, or 2.2% of the total. With the current reward of 100 IFC per 2 minutes this is about 1575 IFC per day.
My main concern is that you spend time setting things up, then difficulty increases as more miners jump in to take advantage of the current reward system. For example, difficulty has increased by about 4 times in as many days. The chance of winning blocks is inversely proportional to difficulty, so if difficulty increases by (say) another 4 times, the daily estimate will be a quarter of what it is now. If difficulty went up by (say) 10 times you'd only be making 157 IFC per day. I don't want you to waste your time only to be disappointed because your already small mining output dries up as more miners put their own hashpower into this coin.
Anyway, if you do decide to continue, this page, although old, should assist you with setting up the software:
