dwarfexport is an IDA Pro plugin that allows the user to export dwarf debug information. This can then be imported in to gdb and other tools, allowing you to debug using info you have recovered in IDA even when you cannot connect the IDA debugger.

Pre-compiled copies of dwarfexport are available in the bin folder of this project. Just add these files to your IDA plugins folder (plx and plx64 for linux, plw and p64 for windows) and you will have a new option "Edit->Plugins->Export Dwarf Debug Info". Click this and select a folder for the output.

The plugin will generate two files in the output directory. One will be a .c file with the decompiled functions from the Hexrays decompiler. The other is a .elf file that contains the debug information. Note that because the plugin performs decompilation on every function in the binary, it can take a while to run.

Move these to the device you want to debug on and load gdb (e.x, gdb a.out), then from gdb, run:

(gdb) symbol-file a.out.elf

Afterwords you will have full debug information, like normal gdb with source (shown below using TUI mode):

dwarfexport depends on the IDA SDK as well as a libdwarf. Once you have these available (a statically compiled copy of libdwarf is provided), you can set the environment variables IDASDK_PATH and IDA_PATH to the SDK path and your IDA folder location respectively. Then build the plugin using make.

No instructions are currently provided. I'm using a series of hacks that I will clean up and document at some point.
