Instrumenting and running your program

To instrument and run your program:

1. Link the program under Purify using the -g option to collect debug data:
   
        % purify cc -g <myprog>.o
   
   or, if you compile and link at the same time:
   
        % purify cc -g <myprog>.c
   
   Note that you can modify your existing makefiles to compile and link your program under Purify. For more information click
    

2. Run the instrumented program.
   
        % a.out
   
   This results in normal program output, and opens the Purify Viewer (unless Purify is unable to connect to an X Window display). Note that the program does not stop processing when Purify finds an error.

The next step in using Purify is to analyze the Purify error messages.
 

Note:

• To instrument a program on IRIX, you have the option of adding purify in front of the compile/link command line as on other platforms, or of instrumenting the executable:
  
       % purify a.out
  
  To run the program, type:
  
       % a.out.pure
   

What else can you do?

• Use Rational PureCoverage with Purify to make sure you're looking for errors in all your code.

• Customize your error checking using Purify's advanced features, API functions, and options.

• Save Purify output to file.
