Topic: CCminer M7 (XCN) by djm34, fixed + optimized for cuda 8 and new cards by PALLAS - page 9. (Read 52620 times)

I'm using 16.04

I compiled well on ubuntu 16 and cuda 7.5(a bit faster) , -D_FORCE_INLINES option to nvcc compiler in Makefile fixes CUDA7.5 related errors



apt-get install libcurl4-openssl-dev

not

 apt-get install libcurl4-openssl-dev 7.47.0-1ubuntu2.1

@pallas - what should I be compiling this in - Ubuntu 14.04 or 16.04?

Use the openssl one. Cut and paste the name of the package or use the tab key for auto completion.

Now this error:  Most frustrating!

Don't install cuda-toolkit, install cuda8 run file instead.
What errors are you getting?

Ok - I am not having more issues then before:

Would someone please list the tools that are needed in order to compile this?  Let's say I start with a fresh install of Ubuntu 16.04 -

I know after install I do the following:
sudo apt-get upgrade
sudo apt-get update

then what tools and order do I need to compile this source?  I have so many tabs open I am getting lost on build-essentials, automake, autoconf, cuda toolkit, I keep getting error after error.

Thanks,
pokeytex

That's a bit OT but zcoin lyra implementation is very hard on GPU, as the lyra matrix grows with block height. Surely possible to do, likely to be slower than cpu.

What about Zcoin? Did you made a gpu miner? I achieved 74h/s on dual E5-2690 by compiling with icc...

No and no.
You can mine on 1gh and trade on btc38 or bter.

Pallas, you can open the source of optimized version - it is not needed anymore... xcn pool will be last pool and last node of XCN. Complitly dead.. I think you are mining Zcoin on GPU. What is your hashrate on single 1070?

I just received this message on suprnova:
This pool will be closing soon as Polo removes XCN from the Exchange - please move over to xcn.1gh.com - Thanks !

Thats it..XCN finally dead..

Thank you pallas - I will try again today.

It is hard teaching a Windows user Linux - But I refuse to give up.

It's all available in the coin thread, look in the last page.

Updated wallet? Huh anything we can also use?
You have the current blockchain..maybe you can also offer it for download somewhere so we get a better syncing for all people.

Ah what i wanted to ask..you complied now on Ubuntu 16.04? Or still 14.04..stoneage :-D

I wouldn't say "weak network" but "weak exchange": they are unable to run the wallet, I offered to help, given them the blockchain and a patched wallet, still nothing. I think they just want to reduce supply in order to pump it.

Looks like XCN gets delisted from Poloniex due to weak network and transaction explorer the lack of it.
So its getting pointless to mine this coin right?

Here it is! :-)

New commit: "GCC 5.4 and cuda8 final build fix"

Enjoy!
