Subject: How do I patch my binary
Date: Tue, 23 Nov 2010 21:31:00 -0000	[thread overview]
Message-ID: <F7CE05678329534C957159168FA70DEC572E758BCA@EUSAACMS0703.eamcs.ericsson.se> (raw)

Hi,

There is doc section "Patching Programs".  This got me hoping I could somehow 
patch my binary while I was debugging.

My hope was that I could modify the source code (outside of GDB), recompile 
the binary and have GDB load and use the new binary, without having to restart 
the program.  I couldn't get this to work (using 'set write on' and reloading
the new binary).

When the doc says "Patching" does it mean I actually have to modify the memory
where the code is written, using GDB commands?  Or can I do it high-level
like I originally hoped.

Thanks

Marc
