CCminer M7 (XCN) by djm34, fixed + optimized for cuda 8 and new cards by PALLAS

[bensam1231]

Weird there isn't anyone around willing to compile this. I even offered some devs BTC to compile it and fix the bugs, no one has responded.

[sibisi666]

hm, is there source code? just require compile?

yes it's on git, see first post.

what version there is there on git, the one that does 20MH?

the one that works on cuda8 and pascal and is about 10% faster than the code base (djm version).

someone must rewrite this(join in one function) to prevent to many memory writes... like Tanguy Pruvot did with lbry miner.

no, it will be much slower.
you can do it with lbry because they are a few little hashes, those are 7 (+ all the muls) and some are much heavier (like whirlpool).

Would there be much involved in changing the cuda toolkit used to 8.0 so it compiles with VS2015?

[pallas]

It does use cuda 8 already and compiles fine on linux and, I assume, Windows with mingw. For visual studio, I think you need to update the project file.

That's what I thought but when using the master branch from github it tries to use 6.5.

line 54: "The imported project "C:\Program Files (x86)\MSBuild\Microsoft.Cpp\v4.0\V140\BuildCustomizations\CUDA 6.5.props" was not found"  I only have 8.0 in that folder.

Honestly this topic is ...
Still no windows compile after few weeks.
We better donate to tpruvot, he's the man !!

nvcc is not in the PATH.
find it and then:

export PATH=***nvcc directory***:$PATH

if you install cuda by .run file, it will be into a subdir of /usr/local, don't know about the deb method.
you can run "find / -xdev -name nvcc" if unsure.

OK, GOOD, NVCC IS THERE--

But, then "make" failed on not finding "gcc-4.9".  An attempt to install v4.9 revealed that  gcc-4.9 was up-to-date.  I then created a symlink to the "/usr/bin/gcc-4.8" directory with "sudo ln -s /usr/bin/gcc-4.8 /usr/bin/gcc-4.9".  

On returning to the "pallas" directory, I issued the command "make", and the compilation continued from where it had errored out.  The compilation is running while I type this.  

VOILA'  It compiled!!!! I  ran the "--help" command.  Right now, the machine is mining Ethereum (ETH), and I will check out your work sometime today.  Thank you, Pallas!

Evening scryptr - I tried your method above - in full disclosure - I am a Ubuntu noob.  I keep running into this error and have tried now for 24 hours with no luck to get past this point.  I am running Ubuntu 14.04 LTS.

your system headers have those typedefs already defined. probably gcc 5.4, the issue wasn't there with older compilers.
you need to remove those definitions at the beginning of the related files.
there are a bunch.
or use gcc 4.9 (the default for this fork).

@pallas  I am not sure what you mean by typedefs.  I am running Ubuntu 14.04 - clean install on an intel box.  I believe the 64 bit version.  I installed all basic stuff and have followed along on all of the tutorials so far.  The error I am getting is based in GCC - I downloaded gcc 4.9 but get the same error still.  I refuse to give up! :-)  Any more advice please?  With a cherry on top!

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?

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.

[ioglnx]

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
