Litecoin-qt Debian / Dogecoin hashrate wallet

cpuminer is a miner program for Litecoin and Bitcoin cryptocurrencies. It runs on CPUs (it does not need a graphic card to run).

By default it uses scrypt algorithm, but it can be configured to use SHA-256 one.

Build cpuminer from source code:

In order to build cpuminer from source code we will download its source code from its repository:
$ sudo aptitude install git
$ git clone
$ cd cpuminer
$ less README

Next we install some dependencies to be able to build it.
$ sudo aptitude install automake
$ sudo aptitude install pkg-config
$ sudo aptitude install gcc
$ sudo aptitude install make

NOTE: without this package: "possibly undefined macro: AC_MSG_ERROR" error appears
$ sudo aptitude install libcurl3-gnutls-dev

Create configure and Makefile files:
$ ./autogen.sh
configure.ac:15: installing './compile'
configure.ac:4: installing './config.guess'
configure.ac:4: installing './config.sub'
configure.ac:6: installing './install-sh'
configure.ac:6: installing './missing'
Makefile.am:12: warning: 'INCLUDES' is the old name for 'AM_CPPFLAGS' (or '*_CPPFLAGS')
Makefile.am: installing './INSTALL'
Makefile.am: installing './depcomp'

Build the sources:
$ ./configure CFLAGS="-O3"

$ make

A minerd binary file appears:
$ file minerd
minerd: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.32, BuildID[sha1]=dfab35e6312ee764f4ab73e9e10e991aa998d930, not stripped

Launch minerd program:

By default it mines using scrypt algorithm:

NOTE: minerd options
-o: pool to connect to
-u : your worker name in that pool
-p: password for that worker

$ ./minerd -o stratum+tcp://stratum.give-me-ltc.com:3334 -u your_worker -p your_passwd

As an example of performance in my system:

$ grep bogo /proc/cpuinfo
bogomips : 4255.53
bogomips : 4255.90
bogomips : 4255.91
bogomips : 4255.91

4 Gigabyte of RAM.

$ uname -a
Linux debSOne 3.2.0-3-amd64 #1 SMP Mon Jul 23 02:45:17 UTC 2012 x86_64 GNU/Linux

It gets a total: 10.54 khash/s
