[ANN] Litecoin - a lite version of Bitcoin. Launched!

[coblee]

twobits very specificly stated that he would appreciate if people didn't mirror the download link to his miners. You might want to check up on that.

Ok, I removed the mirror link from the first posts. I can't be sure that it's not compromised. The wuala link is good though.

Well, you can just checksum it, but I'd consult with twobits first.

Of course. But I'm not familiar with the mirror sites enough to know that the uploader can't switch out the binary in the future.

@coblee: OK, just consult with twobits first and then upload original binary on safe location which is reachable from China too.
(github maybe?)

@Kumala: is github reachable from China? Or just offer some good file sharing site.

Also, you may need to configure it for your machine to get the optimal speed. Check the README file. Somewhere on the forums, people have suggested running configure like this:
    CFLAGS="-march=native -O3 -Wall -msse2 -msse3 -msse4.1 -msse4.2 -msse4 -mavx" ./configure
OR
    CFLAGS="-march=native -O3 -Wall -msse2 -msse3 -msse4.1 -msse4.2 -msse4" ./configure

Actually what you do is compile it with all flags you listed then run it and see if it fails.
If it fails then remove the last flag from the Makefile/makfile (line that starts with CFLAGS = ), 'make clean' 'make' and run again.
You keep doing this 'remove the last flag' until it works (or look up your CPU and work out what flags are valid )

For linux try cat /proc/cpuinfo |grep flags to get them for OSX sysctl -a |grep cpu.features gets them and don't use the -march= or it will tell you your C compiler cannot produce executables, for the Doz yep look it up.

Yep I was just giving the simple version for anyone not certain of exactly what options they have or how to get it right

Edit: meanwhile ... LTC peaked to 0.01 BTC on BTC-E not long ago

Anyone can explain how to build litecoin in ubuntu 11.10?

It's pretty easy, just follow these instructions:

Compiled LTC miner on Ubuntu 11.10 4 days ago so its instructions just for it (Live version too):

1.Open terminal
2.Type: sudo su
3.Type: apt-get install gcc libcurl4-nss-dev automake autoconf git make
4.Type: y if asked
5.Type: git clone git://github.com/Lolcust/Tenebrix-miner.git
6.Type: cd Tenebrix-miner/
7.Type: ./autogen.sh
8.Type: CFLAGS="-march=native -O3 -Wall -msse2 -msse3 -msse4 -msse4.1 -msse4.2" ./configure
9.Type: make
10.Type: ./minerd --algo scrypt --url http://lc.ozco.in:9332 --user camopejb.1 --pass 1234

After each command press Enter  
If you don't want to type you can do Copy/Paste in terminal with right click

So you edit the makefile.unix to something like below changing to proper version number for the .a file.

Code:

LIBS= -dead_strip \
 $(DEPSDIR)/lib/libdb_cxx-5.1.a \

I installed the db
>sudo apt-get install libdb5.1++-dev
and added the library to the build path like coblee told me and it compile !

I think he was asking for instructions for the client, not miner.

[CAMOPEJB]

Ummm... you're right!
But, it is good thing to have instruction for miner too 

[coblee]

Due to the rumor of a possible 51% attack, I decided to lock in block 23420 in the latest code. Everyone, please grab the latest source or download and use this Windows binary:
https://github.com/downloads/coblee/litecoin/litecoin-windows-client-0.5.0.4.zip

Chances are the rumor is probably unfounded, but better be safe. Plus if you haven't downloaded the recent clients, you will find a cool mining tab waiting for you to play around with.

Nice job coblee

nice, updated aswell

And you can have ~20% more hashing power on Ubuntu live

Where can I find instructions for installing/using a miner with a Ubuntu live CD?

Ok, I have Tenebrix-miner running now.  The output says:

Code:

thread 1: 13695 hashes, 3.07 khash/sec
PROOF OF WORK RESULT: true (yay!!!)
thread 0: 10568 hashes, 3.09 khash/sec
PROOF OF WORK RESULT: true (yay!!!)

In my ozco.in account, it says my worker has a hash rate of  4KH/s

Is this reasonable?  Shouldn't it be in the MH range?
