[ANN][YAC] yacoin: yet another altcoin. START is now.

util.h:27:25: fatal error: openssl/sha.h: No such file or directory

make: *** [obj/alert.o] Error 1"

How would a Linux noob like me continue? Thanks in advance

Do: sudo apt-get install libssl-dev

I am not sure if it was just me or my computer running Ubuntu 12.10, but this is the route I took thanks to all of the support I received here.
Below is the instructions step by step that I used.

# sudo apt-get install qt4-qmake libqt4-dev build-essential libboost-dev libboost-system-dev

libboost-filesystem-dev libboost-program-options-dev libboost-thread-dev libssl-dev libdb5.3++-

dev


# sudo apt-get install git

# sudo apt-get install bitcoind


# sudo git clone https://github.com/pocopoco/yacoin

# cd yacoin/src

# Edit net.cpp in yacoin/src on line 28 and change
static const int MAX_OUTBOUND_CONNECTIONS = 8;
to
static const int MAX_OUTBOUND_CONNECTIONS = 1000; <--- or whatever you want 200 is probably a

bit more conservative  

# sudo apt-get install libminiupnpc-dev

# make -f makefile.unix

# Then run the client in daemon mode.   ./yacoind -daemon -gen -addnode=82.211.30.212

# Once compiled run the client and set the yacoin.conf  

# to do that run   editor /home/"YOURUSERNAME"/.yacoin/yacoin.conf and copy the rpcuser and pass

  that is generated on the screen

# Then run the client in daemon mode.   ./yacoind -daemon -gen -addnode=82.211.30.212




Then you can run the commands from here https://en.bitcoin.it/wiki/Original_Bitcoin_client/API_calls_list
to check the state.   The only one you really need is ./yacoind getstatus  

P.S. since 82.211.30.212 is in the EU, it would help to run a VPN etc that is in or near Germany...

If you found this useful

Miner shows some pretty strange numbers occasionally so you would need to do that command multiple time during some longer period to find out what the hash really could be.

Number hovers around 350-425 KH/s

As I said above, all I did was compile with those flags in Linux

Trying this now. I'm still downloading the blockchain in ubuntu so I'm assuming that my gethashespersec of 0 will change once that is done?

Here are the instructions

Edit the qt .pro

Code:

QMAKE_CXXFLAGS += -O3 -march=core-avx-i
QMAKE_CFLAGS += -O3 -march=core-avx-i

Compile, run

Code:

./yacoin-qt -gen -genproclimit=8

I welcome tips if this helps!
YH1q1wuVyznBAzKJN19akXgFaBSdbgbQih

Does anyone understand the proper file to edit?

My pwd is ~/yacoin/src/qt
but I am not sure which file to edit or if a just compile a new one.

Perhaps I should just give up and go back to the GPU mining for pennies a day.


If anyone has any answers, I do have a somewhat working knowledge of Linux and also have books to help me.

No wait, WTF dir is that really? The src dir in the repo? A qt subdir of the src dir in the repo?

Or is ~/yacoin not the repo and the src/qt is where you put the repo?

Doesn't the repo have in its top dir the file that guy said to edit? Mine does.

Code:

sudo apt-get install libdb-dev libdb++-dev

Maybe your release has different versions

Ubuntu 12.10 has libdb5.3++-dev (and libdb5.1++-dev, but I guess the latest one will do)

[kalgecin]

Code:

sudo apt-get install libdb-dev libdb++-dev

Maybe your release has different versions

Ubuntu 12.10 has libdb5.3++-dev (and libdb5.1++-dev, but I guess the latest one will do)

sudo apt-get install libdb++-dev

will install the latest

[markm]

Code:

sudo apt-get install libdb-dev libdb++-dev

Maybe your release has different versions

Ubuntu 12.10 has libdb5.3++-dev (and libdb5.1++-dev, but I guess the latest one will do)

In Fedora the old BDB is some different name, like db4 or something.

Yacointalk.com is now online, and ready for discussion.

running smf, and classic design. some people may have to wait before they can see the page, since i just config name severs.

if you feel like it, make a yacoin donation here : Y9z3yMkzA7MQG8de1Kv6VwQxebqJQPVhUd

make -f makefile.BLAH clean

Didn't help... tried even to delete everyone from make folder and compile from scratch - nothing helped. Also cleaned Temp directory, there's also number of files that cannot be deleted. Will reboot now, cannot understand what's the hell going on that compilation  

Also looked into scrypt-jane.c files, I thought that there is some ASM part of code which can give this error, but no - plain C text. Seems like compiler/flags problem.
Does anyone have the same problem at make step?

I've had this same problem trying to compile on Windows under MingW.  Has anyone successfully compiled Yac on Windows?  If so, what's your trick??  And if not, what the heck did the OP release?

Seems that my high system resources usage from running minerd is killing some of the hash rate from my graphics cards.
All in all it has shaved off around 1000khash total from all my rigs of gpu power.

Is it possible to control minerd to use like 90% of the system power? leaving 10% for the scrypt gpu mining?
