Building a Project

Building a project creates a .sav file of your project or compiles your project based upon the options you have set for your project. If you have specified:

Source File — The IDL session is reset (all procedures, functions, main level variables, and common blocks are deleted from memory), all files in the project are compiled, and all undefined but referenced functions and procedures are resolved.

For more information on resetting an IDL session, see .FULL_RESET_SESSION. For more information on resolving undefined but referenced functions, see RESOLVE_ALL.

Save File — The IDL session is reset (all procedures, functions, main level variables, and common blocks are deleted from memory so that unwanted items are not included in your .sav file), all files in the project are compiled, all undefined but referenced functions and procedures are resolved, and all the functions and procedures are saved into the file you specified in the project's options.

The save file is created using the XDR and COMPRESS options. For more information, see SAVE.

Licensed Save File — The IDL session is reset (all procedures, functions, main level variables, and common blocks are deleted from memory so that unwanted items are not included in your .sav file), all files in the project are compiled, all undefined but referenced functions and procedures are resolved, all the functions and procedures are saved into the file specified in the project's options, and embedded license information is added to the save file.

For more information on how to create a licensed save file and distribute IDL Runtime with your application, contact your ITT Visual Information Solutions sales representative.

Open your project. Select File

Open Project. Select the path and name of your project file.

Select Project

Build. A dialog appears, confirming that you want to reset your session.

This will delete all procedures, functions, main level variables and common blocks from memory. If you have the save file option selected for your project, this will ensure that these items will not be included in your .sav file. If you have the source file option selected for your project, this will ensure that you have a clean environment in which to run and test your application.

Click OK.

About IDL GUIBuilder Files

When you build your IDL Project, the IDL GUIBuilder (.prc) files are automatically compiled and the resulting source (.pro) and event (*_eventcb.pro) files are automatically added to your project.
