raid is a GDB-like tiny debugger which is based on ptrace.
Before everything start, we'll need to clone submodules linenoise and elfutils first.
$ git submodule update --init
We may need to install some dependencies to build elfutils, and you'll need to
move libdw.so to the top level of repository after build. All of these works can be done
using the following script simply. But I'll recommand you to take a look at what will be
installed after running the script first.
$ ./scripts/install-libdw.sh
Then we can build the debugger with all of the dependencies included.
$ make
Finally, it's time to play with raid now! Debugging your executable with the following command.
$ ./build/raid executable
raid has been implemented a small set of command, which can let you do some simple trace on the debuggee.
| Command | Description |
|---|---|
| help | List all of the supported command of raid |
| cont | restart tracee until it hits a breakpoint or finishes execution |
| break | Set a breakpoint on tracee |
| watch | Watch a variable when it is modified |
| step | Step in to the next line of source file |
| next | Step over to the next line of current function |
| backtrace | Unwind stack for the chain of function calls which leads to the current point |
| Print current value of a variable or register | |
| quit | End the execution of debugger |
