This entry explains how to,

1. Checkout the latest revision
2. Configure root with desired options enabled or disabled
3. Install necessary libraries to support selected options
4. Compile
5. Setup Ubuntu environment properly  to work root properly at any directory

sudo apt-get install g++ g++-4.4 libstdc++6-4.4-dev g++-multilib g++-4.4-multilib gcc-4.4-doc 
libstdc++6-4.4-dbg libx11-dev libxpm-dev libxft-dev libxext-dev

This will enable to compile the basic version of root with following options enabled

1. asimage
2. astiff
3. builtin_afterimage
4. builtin_pcre
5. cintex
6. exceptions
7. gdml
8. genvector
9. memstat
10. minuit2
11. reflex
12. roofit
13. shadowpw
14. shared
15. table
16. tmva
17. x11
18. xft
19. xrootd

So If you satisfied with these set of options run,

./configure linux --enable-minuit2 --enable-roofit --enable-table --enable-gdml --enable-pgsql
--enable-mysql

If you want to enable more features like mathmore and fast fourier transform install following packages as well,
Install these optional packages,

sudo apt-get install gfortran ncurses-dev libpcre3-dev xlibmesa-glu-dev libglew1.5-dev libftgl-dev
libmysqlclient-dev libfftw3-dev cfitsio-dev graphviz-dev libavahi-compat-libdnssd-dev libldap-dev 
python-dev libxml2-dev libssl-dev libgsl0-dev gfortran-multilib gfortran-doc gfortran-4.4-multilib 
gfortran-4.4-doc libgfortran3-dbg glew-utils ocaml-findlib libtool-doc gsl-bin build-essential 
libjpeg62-dev libtiff4-dev  libgnutls-dev libgmp3-dev libxmu-dev libpng12-dev libkrb5-dev
freeglut3-devlibxmu-dev libgif-dev libgif-dev libiodbc2 libiodbc2-dev

Now root will support following options

1. asimage
2. astiff
3. builtin_afterimage
4. builtin_freetype
5. builtin_glew
6. builtin_pcre
7. builtin_zlib
8. cintex
9. editline
10. exceptions
11. fftw3
12. fitsio
13. gviz
14. gdml
15. genvector
16. krb5
17. ldap
18. mathmore
19. memstat
20. minuit2
21. mysql
22. odbc
23. opengl
24. python
25. reflex
26. roofit
27. shadowpw
28. shared
29. ssl
30. table
31. tmva
32. x11
33. xft
34. xml
35. xrootd

./configure linux --enable-minuit2 --enable-roofit --enable-table --enable-gdml --enable-pgsql 
--enable-mysql --enable-builtin-zlib --enable-builtin-pcre --enable-builtin-freetype
--enable-builtin-glew

Now compile source,
use

make

or

make -j no.of-cores-you-have

Finally set the environment variables in your favorite  shell,

#
# ROOT path configuration
#
export ROOTSYS=$HOME/softwares/root
export PATH=$ROOTSYS/bin:$PATH
export LD_LIBRARY_PATH=$ROOTSYS/lib:$LD_LIBRARY_PATH

Open a new terminal and type,
:~$ root
