sdebugger

A simple x64 debugger for Linux on development

Building

You will need cmake in order to build properly:

mkdir -p build/
cd build/
cmake ..
make

Using

For now still veeery simple.

./sdebugger <binary>
debugger> r // Spawn child process (run)
debugger> b <addr> // Add a breakpoint to a given addr (break, breakpoint, b)
debugger> dumpr // Dump registers, put a breakpoint before
debugger> s // Make a single step (step,s)
debugger> cont // continue where its stopped or start process (c, cont, continue)

Example

$ objdump -DM intel ../examples/hello | grep '<main>'                                                                                                                                       
289:0000000000401122 <main>:
$./sdebugger ../examples/hello                                                                                                                                                             debugger> r
