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., egcs on a platform where only gcc 2.95 is installed. In such cases you'll have to install ROOT from source.
Note 2: ROOT supports TrueType fonts also on X11 systems. On how to get TrueType font support in ROOT enabled see the TrueType install page. Please read this before downloading a binary version.
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%\binThe h2root utility requires a Fortran DLL called dformd.dll. In case you do not have this library already installed on your system, you can ftp it. Some old Windows systems may also require MSVCIRT.DLL. For NT get the OpenGL that "fixes Color Problems Using Service Pack 2 for NT 4.0".
To install, unzip and untar the file. For example:
$ gunzip root_v2.25.03.HP-UX.B.10.20.tar.gz $ tar xvf root_v2.25.03.HP-UX.B.10.20.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.
