Third Party Software

Before compiling and installing the OSA SW from the source code you have to make sure that the following packages are installed:

1. GNU make version 3.79.1 (or higher)
   You really need this version of GNU make for all platforms. Most Linux distributions will already include the correct make. Earlier versions of GNU make are known not to work.
2. ROOT version 5.34.34
   available via the ISDC website at URL http://www.isdc.unige.ch/integral/analysis#Softwarein the section on `Download OSA for Developers'.
3. gcc and gfortran version 4.4. This version works, later and earlier versions might not.

Since OSA software version 3.0 you can choose between an installation with and without ROOT. If you choose to install without ROOT, you will NOT benefit from all OSA functionalities, i.e. GUI support is not available. To learn more about how to install OSA without ROOT please see section `Setting up the Environment'.

For other operating systems it is recommended to install ROOT from the source code. If you want to download ROOT as a binary package, you must make sure that the compiler used to compile ROOT is identical to the one you are using for the installation of the OSA SW. Otherwise, please download the ROOT source code package and compile and install it yourself. Using different compilers may result in serious problems with your X-system.
