[Qemu-devel] GDB help

[Jean-Michel POURE]

Dear friends,

I am trying to run the following GDB session over a Windows XP pro 
installation disc:

root@station:/home/jmpoure/projets/qemu/winxp# gdb qemu

qemu was compiled from CVS. Any idea how I can get these debugging symbols?
Then, how do I display a trace when the process detaches? Can you make a 
detailed description for newbees? Thanks in advance.

Cheers,
Jean-Michel

Use the executable in qemu/i386-softmmu. The symbols are stripped from 
the installed version. But be warned, debugging QEMU with gdb is not 
easy, especially if the errors are in the dynamically generated code.
