Re: what are the created ~b files when using -g with gnatmake

[srouse@iastate.edu (srouse)]

Thank you for your help!

Sorry about the "~b" typo!

I have a couple more questions though...

I'm creating an IDE for Ada in Eclipse and working on the debugger
right now, so I'm trying to get a knowledge of how to debug Ada
programs.  All my code is programmed in Java so I'm very familiar with
how to debug Java programs.  With a Java program I step through the
code that I have written.

This is what I don't understand:

If I have a project in GPS and go to debug it, I step through the
created b~xxx.adb file.  Why would I not step through the xxx.adb
file?

I have been looking through the gnat user guide and gnatgdb debugger
doc a great deal, but I still don't understand why the debugger steps
through the b~xxx.adb file and not the xxx.adb file.

Thank you for any additional help!
Shawn
