How do I enable debugging? I checked the configure file and I do not see any options for compiling with debugging, i.e. there is no --enable-debug option. I see that the "default parameters" section of the configure file sets: gdbstub="yes" but other than that i do not see any other reference to debugging.
Also, I am working with qemu source code, which I configure, make, make install before every run. Thank you again. On 10/12/07, J.
