Fortunately your near the end of the path... (pun intended).  [You need to add QT/bin to the end of your PATH variable]

If you prefer, just do the qmake from a windows command prompt or whatever environment you had it running it before.  The key is to build the libleveldb and libmemenv first as shown in the example.

Just received (3) Antminer U2s to augment my (6) Antiminer U1s.

I originally tried running them all together on an Anker 10 port hub with a 5amp 12V power supply, and they started to work, but one was freaking out with hardware errors.  All 9 were launched with a x0981 speed parameter.

Move the three news ones to a cheap powered hub with a 2amp 5V power supply and a different miner machine so I could isolate and watch them.  At x0981 the problem child still complained, but runs steady at x0881.  Alas, after several hours the performance dropped to <0.50Gh/s, even though the short term counter indicated 2Gh/s.  No hardware errors.

Have just dropped down to x0681 (the default) to see what the multi-hour impact is.  If it runs stable, I'll move the two good ones back to the Anker hub and leave the problem child on the cheapie hub.

Open a MinGW window and:

cd /JennyCoin/src/leveldb
TARGET_OS=NATIVE_WINDOWS make libleveldb.a libmemenv.a

Then...

cd ../..
qmake JennyCoin-qt.pro
mingw32-make -f Makefile.Release

The biggest problem with multiple sticks on usb hubs is insufficient power.  I'm running 6 at the moment, but have an large power supply on it.  Search the BFGminer/Antminer thread and you will find several recommendations on hubs that work well (warning, none are $19 units, but many are under $60).

Thank you Thank You.  Please talk your friends into downloading a wallet.  Network hashrate and difficulty is still low enough to CPU mine blocks/week - which is nice for people just wanting to get started.  Don't know how long that will last.

Seems we bottomed out  network hash rate rise over the weekend and are climbing back up again.

Understood.  Thank you.

Thanks for the quick reply.  I noticed it was IRC based as well.  So if all the coins are distributed, what is the point of running it?  Day trading?

Hey, mind taking a look at Faircoin? It needs an exchange as well. We're trading on NXT-E, but it's not an exchange dedicated to volume trading. Lazycoins would do the job!!

If you've never heard about Faircoin, it's a revolutionary alt with the fairest distribution of all time.

Fair-coin - given that all coins are distributed within the 1st 5 day or ~47K addresses, what day and address are you up to?

Do you have a statically linked Windows executable and dnsseed network?

Can you share you start script?  It almost looks like you still have --scrypt in there and are going against a SSH-256 coin?  Is that possible?

Hi guys...

Are you going to be supporting nscrypt anytime soon?  Saw a coin launch today that requires it:  "tenfive" (aka 10-5).

Try the [H]elp key... just punch "h".

YACCoin (with 2 C's) would be honored if you would consider adding us to your exchange.

Basic info here:  https://bitcointalk.org/index.php?topic=514739.new#new

The development team is online about 20 hours a day (compliments of being on both sides of the Atlantic), so please feel free to ask any questions.

Thank you in advance for your consideration,

March 23rd, 2014 Maintenance Release

Highlights include:

* (2) addition checkpoint hashes for added blockchain protection
* Client version numbering change in order to allow us to track which client people are connecting with.  This will be incremented new versions become available.
* Protocol version increment.  This will occur anytime new checkpoint hashes are added.  This will allow us to force the wallet version should the blockchain ever fork.  Not a perfect solution to that problem, but we are confident it will help.
* Connection settings tightened up.  Connections will be banned after 16 abuses instead of the default 100, but only for 4 hours, vs, the default of 24 hours.
*  Connection age will be limited to 3 days in your peers.dat hopefully eliminating all the wasted time associated with trying to connect to someone who hasn't been on the net is a weeks.
*  10 connection failures over 2 days will be allowed vs. the default of over 7 days.

We believe the above changes should help speed up resyncs and reduce overhead of trying old, stale, connections as well as provide us some important debugging and control points should we need them in the future.

YACCoin History:

Since its original launch on February 12th, 2014, YACCoin has evolved.  We are now using the Kimoto Gravity Well for better control over difficulty, and have disabled UPNP for the protection of our user base.  Of course, as the block chain has grown, we have been adding additional checkpoint hash keys to protect it.  YACCoin has always been, and will always be, 100% IRC free.  Like disabling UPNP, our development team believes the use of the IRC network unnecessarily exposes our user base to potential security threats.

We are pleased to announce that YACCoin was chosen as the first of eight cyber coins to be used in the new upcoming 1BillionHex game.  Mine now and spend later in the game!  It will also be the first alt coin to be accepted for digital download payments on 1BillionHex.com.  https://www.1BillionHex.com/

YACCoin is simplicity itself for Windows users - just grab the executable and go.  No zip files or special directories needed.

CPU miners will find that the current YACCoin difficulty allows for successful CPU mining on a weekly timescale.   All mined blocks are rewarded with 1024 coins!  The development team continues to seek ways to reward CPU miners since they greatly enhance our network.  Please post your suggestions on our forum!

You won't ever have to worry about adding "Addnode=" statements into your configuration file either - The YACCoin network has multiple seed nodes and a fully functional DNSseed system enabling rapid, automatic, connections and syncing.

As all real developer based coins should have, YACCoin has a fully function -testnet network available if you wish to utilize it.

Of course, full source is maintained at https://github.com/yaccoin/yaccoin.

Windows, Mac OS, and Linux wallets are available at our official website in the download section, although we highly encourage Linux/Unix users to compile their own from the git source.

The YACCoin team believes that security, sustainability, and growth are the most important factors for the coin and are continuing to search and implement methods of improving all three.

Please come join us!

Cassey, lead YACCoin developer, on behalf of the entire YACCoin team.

I previously reported an issue with --load-balance apparently impacting the performance of my GPU miner.  Today I replicated with my Antminer ASIC rig.  Please note the only significant difference between the two outputs below are the use of "--load-balance" with quotas vs. the use of "--balance".  Run times are similar and done back to back on the same hardware on the same system.

The --load-balance rig averaged 2.39Gh/s over 26 minutes with 36 hardware errors.
The --balance rig averaged 11.96Gh/s over 27 minutes with 0 hardware errors.

I'm happy to volunteer the rig for testing if that would help resolve this - I really, really like the control --load-balance would provide me if I didn't take the performance hit.

Absolutely!  At block 31037 and running well!

I recently have started having some shutdown errors.  Program works fine, just generates stuff like what is below when I shutdown via q.

Ah, I had a mix of accepted and rejected, presumed it was just do to the early testing and ultra low difficulty.  Thanks for clarifying.

Ok.  Guess I got lucky, because my notes tell me this worked back when I was trying it:

./bfgminer -S opencl:auto --gpu-fan 100 --auto-gpu --intensity 18,20 --temp-overheat 90 --temp-cutoff 100 --temp-target 80 --scrypt -t 4 -o http://localhost:6332 -O yaccoinrpc:471EQrAidMjGKb8GYk9P2S4wLcbmKWhNkKXNV4g3vi9M

My congrats on the great job bfgminer does at auto-tuning itself.

I just spent a few hours hand tweaking a MSI R9 270X, with core clock of 1030MHz, and  an advertized boost of 1120MHz.

I found I could take the thread-concurrency up to 28160, memclock up to 1625, and engine up to 1170 with a single gpu-thread.  Best I got, was about 367 MHash.  Not great.

Running  "./bfgminer -S opencl:auto --gpu-fan 100 --auto-gpu --intensity 19 --temp-overheat 90 --temp-cutoff 100 --temp-target 80 --scrypt" with no config file yields 460 MHash.

Digging around, it was using a thread-concurrency of 14114, with one gpu-thread, ran the memclock up to 1625, but set the core clock to 1080 (50 hz over base).  Manually taking it to 1170 (8.3% higher) yielded an additional 7 MHash (1.5%).

What I don't understand is why running at half the max thread-concurrency is faster than running at or near the max the card can handle???

Thoughts?
