#@desc <h3>Launch with <tt>gdb</tt> and <tt>wine</tt></h3>
|
||||
#@desc <p>This will launch the target on the local machine using <tt>gdb</tt> and <tt>wine</tt>.
|
||||
#@desc GDB and Wine must already be installed on your system, and GDB must embed the Python 3
|
||||
#@desc interpreter. You will also need <tt>protobuf</tt> and <tt>psutil</tt> installed for Python
|
||||
#@desc 3.</p>
|
||||
#@desc <p>This operates by starting GDB on the Wine executable and passing arguments to launch a
|
||||
#@desc Windows target. This may prevent GDB from processing the object file, because it is a PE
|
||||
#@desc file, and most copies of GDB for UNIX will support only ELF. Nevertheless, Ghidra should
|
||||
#@desc recognize the target and map it, giving you symbols and debug info in the front end, even
|
||||
#@desc if not in the GDB CLI.</p>
|
||||
#@desc <p>You will need to locate the <tt>wine</tt> executable on your system, not the script. To
|
||||
#@desc find it, either dissect the <tt>wine</tt> script or consult online documentation for your
|
||||
#@desc distribution of Wine. There are often two executables, one for 32-bit targets and one for
|
||||
#@desc 64-bit targets. You must select the correct one.</p>
