Insure++ programs read configuration options from .psrc files. These options control the behavior of Insure++ and programs compiled with Insure++. The .psrc files may be located in various locations in the file system and are processed in the following order of precedence:

  1. The .psrc file in the appropriate lib and compiler subdirectories of the main Insure++ installation directory. For example: /usr/local/insure/cc/.psrc or /usr/local/insure/xlC/.psrc
  2. The .psrc file in the main installation directory. 
  3. A .psrc file in your $HOME directory, if it exists. 
  4. A .psrc file in the current working directory, if it exists. 
  5. Files specified with the -Zop switch and individual options specified with the -Zoi switch to the insure command in the order present on the command line. 

In each case, options found in later files override those seen earlier. All files mentioned above will be processed and the options set before any source files are processed.

Typically, compiler-dependent options are stored in the first location, site-dependent options are stored in the second location, user-dependent options are stored in the third location, and project-dependent options are stored in the fourth location.

-Zop is commonly used for file-dependent options for customization. -Zoi is commonly used for temporary options for customization. See Example Compilation and Linking Commands for details about -Zop, -Zoi and other Insure++ command line options.
