News

Mar 17, 1999: Version 2.21/7 for PPCLinux built from the official source tree.
Nov 1, 1998: Version 2.00/13 for MkLinux built from the official source tree. Be careful that root_v2.00.MkLinux.2.1.24.tar.gz is still v2.00/12.
Oct 21, 1998: A problem found in Version 2.00/12. One has to recompile libBase.so with BASE_Directory.cxx appropriately patched. See Version 2.00/12 building prescription on MkLinux DR3. For those who have already down-loaded the binary package, I prepared the patched libBase.so. Get it and replace the old one in /opt/root/lib.
Oct 15, 1998: Version 2.00/12 for MkLinux became available. Updated Version 2.00/12 building prescription on MkLinux DR3.
Sep 03, 1998: Version 2.00/11 building prescription on MkLinux DR3.
Sep 02, 1998: Version 2.00/11 for MkLinux became available.
Jun 07, 1998: When trying out tests in /opt/root/test, you need to add "$(CXXDEBUGFLAGS) -fno-rtti -fno-exceptions" to CXXFLAGS in order to compile the test programs with egcs's g++. You also have to compile vvector.cxx and vlazy.cxx with "-O0" as follows:

$ make vvector.o CXXDEBUGFLAGS='-O0'
$ make vlazy.o CXXDEBUGFLAGS='-O0'
$ make
if you are using egcs*-1.0-2e. This is unnecessary for egcs-1.0.3a-1a.
May 25, 1998: Version 2.00/07 for MkLinux became available.
Apr 20, 1998: Version 2.00/05 for MkLinux became available. I started using it and found it great. If you know PAW in CERNLIB, it's just like PAW but the command line language is C++! It has a built-in C++ interpreter and executes the standard input, line by line, as a C++ program. You can thus interactively build your analysis program in C++ and later submit it as a batch job.
You can edit resultant plots by your mouse: you can change line-, fill-, and text-attributes at will, and create colorful nice figures quite easily in encapsulated postscript format.
The ROOT is, however, more than a plotting application. You can build various data handling applications based on the ROOT libraries. Why don't you visit the ROOT home page.
The ROOT Home Page is located at

http://root.cern.ch/
from where you can get an MkLinux binary package. The ROOT system is free for noncommercial use unlike CERNLIB.

How to Install ROOT

It's just expanding a tarball:

# tar -zxvf root_v2.21b7_egcs111.tar.gz -C /opt

This binary package has been built with egcs-1.1x and linked with libstdc++.so.2.9. See this for package building prescription.

Getting Started with ROOT

First thing you should do is go through the README file:

$ less /opt/root/AA_README

Then do

$ export ROOTSYS=/opt/root

$ export PATH=$PATH:$ROOTSYS/bin

You can put them into your .bash_profile or .bashrc. You should also tell the system where to find the ROOT shared libraries:

$ export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$ROOTSYS/lib

or you can add /opt/root/lib to /etc/ld.so.conf and do "ldconfig".

Then you can try out a ROOT interactive session:

$ cd <somewhere>/

$ cp -R $ROOTSYS/tutorials .

$ cd tutorials

$ root

CINT/ROOT C/C++ Interpreter version 5.13.78, Oct 22 1998
Type ? for help. Commands must be C++ statements.
Enclose multiple statements between { }.

Welcome to the ROOT tutorials


Type ".x demos.C" to get a toolbar from which to execute the demos

Type ".x demoshelp.C" to see the help window

root [1] .x demos.C

-- Click on Help on Demos.

-- Click on Hsimple first. Then in any order.

-- Move the objects on the canvas around using the mouse.

-- You want also try "first" to see how the C++ interpreter

-- works interactively.

root [2] .q

You can also try ".x benchmarks.C" in the root session to benchmark your machine.

You can also try some sample applications:

$ cd <somewhere>/

$ cp -R $ROOTSYS/test .

$ cd test

$ less README

$ make

$ ./Event

...

$ ./guitest

$ ./hworld

$ ./hsimple

...

Enjoy!
