IN TERMINAL AS ROOT USER TYPE THE FOLLOWING COMMANDS

FIRST INSTALL REQUIRED PACKAGES
apt-get install proftpd gcc g++ make cmake bzip2 libpcsclite1 libpcsclite-dev subversion
OR
apt-get install gcc g++ cmake libpcsclite1 libpcsclite-dev subversion

NEXT DRIVERS DOWNLOAD FOR USB DEVICES
cd /usr/src
wget Download libusb from SourceForge.net
tar xjvf libusb-1.0.8.tar.bz2 (if you missing bzip2 then - apt-get install bzip2 and repeat previous command)
cd libusb-1.0.8
./configure --enable-shared=no
make (if command not found then - apt-get install make and repeat previous command)
make install

NOW WE DOWNLOAD OSCAM SOURCES AND COMPILE
cd /usr/src
svn co oscam - Revision 4971: /trunk oscam
cd oscam
mkdir buid
cd build
cmake .. (those two dots important, if WEBIF is wanted then - cmake -DWEBIF=1 ..)
(if command not found then - apt-get install cmake and repeat previous command)
make

NOW WE WILL COPY OSCAM TO /USR/LOCAL/BIN
cp oscam /usr/local/bin
cd /usr/local/bin
ls
(oscam should be listed here. Next: )
chmod 755 oscam

(Before you start the server make sure you got all 3 oscam config files in /usr/local/etc directory.)

(Don't delete compiling directories, so you can later easily update your oscam version)

TO COMPILE LATEST VERSION NEXT TIME
cd /usr/src
svn co oscam - Revision 4971: /trunk oscam
cd /usr/src/oscam/build
cmake ..
make

If you need to re-complie Oscam, first delete all files from the build directory -otherwise Oscam won't re-compile.
Also, you can determine which modules are compiled using the config.sh shell in the oscam-svn directory (dvapi etc.)
sudo sh config.sh

As long as you are using one of the latest builds the following modules are automatic : -

Active modules:
Webif support: yes
OpenSSL support: no
Dvbapi support: no
Anticasc support: yes
ECM doublecheck: no
Irdeto guessing: yes
Debug: yes
LED support: no
Qboxhd-LED support: no
Log history: yes
Monitor: yes
Camd33: yes
Camd35 UDP: yes
Camd35 TCP: yes
Newcamd: yes
Cccam: yes
Gbox: yes
Radegast: yes
Serial: yes
ConstCW: yes
Cardreader: yes
Nagra: yes
Irdeto: yes
Conax: yes

The ecm doublecheck is an interesting feature if you have identical cards. The Dvbapi feature would not be apllicable on a linux build

Here is the config file at build stage

That is the standard config file but which parameters are amended.
