If you have not already done so, you must install the GLAST-supported compiler on your machine and set up your user PATH. (See Platforms Supported.)

Note: GLAST does not provide this software.

Prerequisites

Refer to Prerequisites: Basic and be sure that you have met all of the prerequisites that pertain to your site before proceeding.

Tips:

• Path

Be sure to set up your PATH to the executable devenv.exe, normally located in:

C:\Program Files\Microsoft Visual Studio .NET 2003\Common7\IDE

• Visual C++

Open the Tools --> Options menu and set your tabs so that spaces are inserted rather than tabs:

• Directory Structure

It is often helpful to create a special directory for GLAST work. This new directory, named "glast" in this example, can then be used to contain subdirectories such as:

Subdirectory	Contains
glast\packages	Source code packages downloaded via CVS from the GLASTOffline CVS repository.
glast\tools	Tools such as CMT, MRvcmt, Doxygen, etc.
glast\extlib	External libraries such as ROOT, Gaudi, etc.
