Although you can debug a regular executable, you'll get much more information and control by building debug variants of the
            executables. To build an executable with debugging information, you must pass the -g option to the compiler. If you're using a QNX Make project, the filename for the debug variant has _g appended to it. 
         
         
         
         To specify the -g option from the project options: 
            
            
         
         
         
         
            - 
               In the Project Explorer view, right-click the project and select Properties. 
               
            
- 
               In the left pane, select QNX C/C++ Project. 
               
            
- 
               In the right pane, select the Build Variants tab. 
               
            
- 
               Under your selected build variants, make sure Debug is enabled: 
               
               
               
                    
 
- 
               Click Apply. 
               
            
- 
               Click OK. 
               
            
- 
               Rebuild your project (unless you're using the IDE's autobuild feature).
