Windows client is in the works for the weekend. I've been very busy this week.

FYI, attempting to compile on linux it throws an error that db_cxx.h is missing (berkeley-db -related file? but then which version of that do I use, where do I get it, and how do I include it?) Also: the .pro file references a Mingw install on an E drive. Lastly, I gave up trying to compile on Windows. Absolute bitch. I have no idea what toolchain, dependencies, and setup it requires. I pieced together what dependencies I *think* it needs from information on compiling litecoin, and then it only complained about duplicate declarations (in the Mingw boost library?) on compile.

I upgraded, but still see the litecoin upgrade announcement?

As long as a single litecoin node is connected to the network this message will appear.
I will change the alert message keys in the next security update or take some other measures to disable these messages.
I am currently evaluating the different options.
The alert messages are annoying but don't impact the performance of the network.

Titan

Ok thanks, np.  Thought it was fixed in this release. All good.    Keep up the great work!

If you all see too many litecoin nodes with port 9333 in the debug.log please erase the peers.dat file and start over again.
The 9917 nodes are the good ones.

Still getting upgrade warning after deleting peers.dat and restarting. No biggy really.
I'm more interested in a Win binary.
No offense Titan but are you the only person working on LKY?

Be well. GL.

Yes, I took over the development of the Luckycoin network and lead the project now.

The updated windows qt client is now available on github.
https://github.com/LuckyCoinFoundation/LuckycoinQT

The linux client client has also been updated to block the litecoin alert messages.

354 (ish ) on I still have to manualy change where the libs are by removing the drive letter and changing the path to where Ubuntu 12.04 stores them.

Code:

INCLUDEPATH += $$BOOST_INCLUDE_PATH $$BDB_INCLUDE_PATH $$OPENSSL_INCLUDE_PATH $$QRENCODE_INCLUDE_PATH
LIBS += $$join(BOOST_LIB_PATH,,-L,) $$join(BDB_LIB_PATH,,-L,) $$join(OPENSSL_LIB_PATH,,-L,) $$join(QRENCODE_LIB_PATH,,-L,)
LIBS += -lssl -lcrypto -ldb_cxx$$BDB_LIB_SUFFIX -loleaut32
# -lgdi32 has to happen after -lcrypto (see  #681)

LIBS += E:\MinGW\lib\libws2_32.a // change to correct location no drive letter /usr/i686-w64-mingw32/lib ( 32 bit Ubuntu )
LIBS += E:\MinGW\lib\liboleaut32.a  // change to correct other slash for Ubuntu / Linux drive slashes
LIBS += -lboost_system$$BOOST_LIB_SUFFIX -lboost_filesystem$$BOOST_LIB_SUFFIX -lboost_program_options$$BOOST_LIB_SUFFIX -lboost_thread$$BOOST_THREAD_LIB_SUFFIX

I highly recomend on the building system you add a path to that drive so it can ' just find ' \MinGW\lib\ ' with out the drive letter, it makes it more portable code, but what would an old guy like me know?  

Code:

Path=$path,E:\MinGW\lib\

Got a whole 5 Luckycoins from mining on P2Pool.org and looks like i'm  the last in the pool and the global is still keeping me under 40% of the hashing  

Edited to add info on where /usr/i686-w64-mingw32/lib is and to change the slashes as Linux uses the ' wrong ' slash for directory trees.

Still trying to get the ' latest' to compile on Ubuntu 12.04 with ( from Ubuntu Software Center ) QT Creator ( and it's green/white icon on the left of my screen ) and a few of the things it complained about being missing.   At this point, I did manage to get the old version to compile, [ leaut32 ] create a wallet and solo mine.  Swapped to a pool pretty quick with what low hash rate the system was doing.  Current Balance as of this posting in LuckyCoins = 5.27978783 LKY  Not bad for using Ubuntu for less than a month 

errors so far with the 'new' version ( besides where MinGW is )

In member funcion 'void MiningPage::minerStarted()' -miningpage.cpp - line 233
- warning - suggest exlicit braces to avoid ambiguous 'else' [-Wparentheses]

ERROR - can not find -loleaut32 -- Ubuntu it's -oleaut32, not -loleaut32, big find/replace not sure if qt-win32.yml[line 50] shoud be made as qt-linux32.yml or not and/or lines 351 and 353 of luckycoin-qt.pro.  353 looks like a conditional LIBS directive ( this ain't no hex edit of a 6502 so i'm guessing on the coding ) that could include a line like Linux:LIBS += -ole32 -uuid -gdi32


ERROR - collect2:ld returned 1 exit status ( )

still poking at it and trying to get it to ' just work ' like the first one did.. error on upgrade on that copy...

[nybbler905]

For Ubuntu 12.04 you will need to use Ubuntu Software Center
needed to enter in the search for software:

QT Creator ( installs icon on the left, we will use this to compile LuckyCoin )
QT 4 ( translation tool, Designer and Document Browser )
IDLE 3 ( python3 stuff )
Python ( just grab version 3+ stuff, it's handy for compiling your miners anyways )
Berkeley ( I used v4.8 of everything grabbable in software center )
mingw ( open and search from file system for libws2_32.a you will need to know where it is later )
ncurses ( did libncurses5-dev for miners might as well grab it now if you don't have it )
Embedded GNU C Library ( bunch of compiler related items, grab the ones you think you need for your system, on Intel, you won't need AMD64 unless you got another pc with AMD Inside )


in a terminal window you will need to do alot of 'sudo apt-get install ( name )'
All lower case, it means act as ROOT access to get/install components.
try with software center first, then from terminal window ( control+alt+t )
name and why.
gcc - compiler ( still for your miners and to do the make of the final wallet)
make - compiler component to do the final ' make ' of the project
autoconf - helps in the make process
qt-sdk - I forget if it was software center or not, click installed then on the bottom for the technical items to ensure you got it.
libboost-test1.48-dev - you never know when you need Development versions of stuff

Once you get it all, time to fire up QT creator, open project/file and point to where you expanded Luckycoin-master and select the .pro file.

left side, click the Edit and go down the .pro file to 354 OR use the bottom search for -lol
highlight and copy ( control+C ) 3 lines, starting with windows:LIBS
un-highlight and past AFTER those 3, incert the pound sign on them ( so we can undo changes and have 3 lines to change )
first, remove the extra letter L from the uncommented Windows line, then the 2 following LIBS need the drive letter removed, and the correct locations for those 2 library files ( from installing MingW )
mine reads as follows
linux:LIBS += -ole32 -uuid -gdi32
LIBS += /usr/i686-w64-mingw32/lib/libws2_32.a
LIBS += /usr/i686-w64-mingw32/lib/liboleaut32.a
SAVE ALL ( and do not toss the compressed version, just in case you need to kill it all, unpack and start over )
click Build and wait, go for a coffee, walk around the house, etc.
it SHOULD create a file called leaut32 in the same folder as the dot pro file.  Open it, it still uses your home folder to store the .luckycoin folder for your wallet and block data.

There may be some ' missing ' software after all that preventing it from compiling.  As you can see, there is little to no mucking with the source to make it ' just work ' in Ubuntu, just a whole lota library upgrading on the build system.  Feel free to mine at P2Pool.org with my luckycoin wallet address of

Thanks for looking into these building issues! I will have a closer look on all your comments when I am back from traveling end of next week.

I have stopped mining on p2pools after seeing strange things happen some weeks ago.
You can easily go solo on the Luckycoin network. The multipool is also highly efficient.

P2Pool.org got some Luckycoins with me mining, too many times solo in the pool and not getting over 23%.
http://www.luckycoinpool.com is where I ( and a whole lot of other people's miners ) are mining away and getting something
 ( Pool Hash Rate   1.256Mhash/s as of when i click post )

Great, thanks for adding hashing power to the Luckycoin network during times of high difficulty.
Now we are through this patch and difficulty is back down to 1.6 and profitability is about 200% again.

had the ' fun' of making a dual core PCI x16 v 1.1 system actually mine with an ATI Radion HD 4850 and tryed to follow my own directions on compiling the wallet.  I keep getting issues related to the version 4.8 database files
"  error while loading shared libraries: libdb_cxx-4.8.so: cannot open shared object file: No such file or directory "

Part of the issue is that the '  current supported ' has moved up to version 6, the other part is that as the current QT creator and the current files to compile do not create a stand alone executable ( stuff it in it instead of using external libraries ).  Something to look in to to make Luckycoin-QT a stand alone aplication once it is compiled.  There are workarounds in Linux ( Ubuntu 13.4 with some things back/down graded due to the HD 4850 ).

Consider this a ' heads up ' and not a complaint

I am running my nodes on Ubuntu 13.04 now. Earlier versions of Ubuntu had some issues with the boost library.
Some libraries have to be installed manually still, but no big deal.

sudo apt-get install git build-essential libssl-dev libdb-dev libdb++-dev libboost-all-dev

[nybbler905]

I had an issue of only fining the ' newer ' libraries and cheated alot to get the already compiled wallet to work
sudo -s
change to where the library files were and copy the newer *.so files to the ' old ' names, only took 3 files and it loaded.  If I could find a way to change the original file or how in QT-Creator to actually copy the files IN to the final file, i'd have uploaded the full files as a branch of the source.

Still.... no big deal..... just need another 20 systems like I have to get my mining at a rate where I could solo mine  

Then again, I wanted to go via the ' challenge ' of getting a HD 4850 up and mining scrypt ( no easy feat even in Ubuntu ) and can still use the desktop with CGMiner set to intensity 14, shaders 800 --scrypt --cpu-engine 600 and hitting 80-89 Cel due to the dying fan ( new heatsink/fan in the mail, may have to do some drilling/tap & die to get it to fit ) and average hash on just that card 89.86KHash/sec.  Good thing that is the rate on just ONE system
