Binaries

Note 1: Before downloading a binary version make sure your machine contains the right run-time environment. In most cases it is not possible to run a version compiled with, e.g., gcc4.0 on a platform where only gcc 3.2 is installed. In such cases you'll have to install ROOT from source. See the configurations used to build the binaries below.

To install, unzip and untar the file. For example:

$ gunzip   root_v5.12.00.Linux.slc3.gcc3.2.3.tar.gz
$ tar xvf  root_v5.12.00.Linux.slc3.gcc3.2.3.tar

This will create the directory root. Before getting started read the file README/README. Remember, you can find the full documentation of the ROOT classes on this web site at the location Classes and Members. The distribution also contains all tutorials and a set of test programs.

For more information see Axel Naumann's web site and also Axel's ftp site.
Note that cygwin/gcc is currently in a very poor status. We strongly recommend to use the win32gdk version above compiled with VC++7.1. The ROOT team will not answer any messages related to problems with the win32gcc version.
Do not untar in a directory with a name containing blank characters.

When running from the MSDOS prompt, you must set the following environment variables, eg in your autoexec.bat: (Restart the system if you set these variables for the first time).

   set TEMP=c:\temp
   set HOME=c:\your top directory
   set TMPDIR=c:\temp
   set ROOTSYS=c:\root  (the directory where you installed Root)
   set PATH=%PATH%;%ROOTSYS%\bin

Note valid for all Windows versions

This version has been compiled with the ANSISTREAM compatibility option. To use this version, you may have to:

Add the option -GX in your compiler options.
In your includes replace iostream.h by Riostream.h
Replace reference to MSVCIRT.LIB by MSVCPRT.LIB when linking.

The win32 versions have been compiled under VisualC++ 7.1. These versions may not run correctly under Windows95 or Windows98 (we do not support these obsolete versions anymore). To use these files with the old VisualC++ 6, you may have to download the following DLLs and store them in a directory accessible in your PATH: You may also need the MSVCR71.DLL file if you have VC++8.

Procedure to install the FREE Microsoft VisualC++ The files described above have been compiled with the commercial version of VC++7.1 under Windows/XP Professional. Installing ROOT with the FREE version of VisualC++ has also been tested by Bertrand Bellenot. See Bertrand's instructions to install this FREE version.
