How to use qemu to simulate a Full OS and debug with gdb?
Hello guys,
I am new to gdb and debug.I'd like to ask you sevral questions about debug linux .
I want to debug drivers like blueZ on linux.I build a costum linux kernel myself and get a vmlinux file.Then,I build a busybox.I can debug by using qemu.But only for the kernel.There is no any drivers and softwares.And I also try to use qemu to run ubuntu,but I cannot get the symbol file.Is there any ideas?
I just install Virtual Machine Manager and QEMU and download an ISO of the distribution i want to work with. Then fire up VMM and create the machine and storage, attach the ISO, install Linux, load my tools, and ready to go. Takes a few minutes, but not long.
Most Linux drivers are modules and come with the kernel. If you want to play games with them, you might want th kernel sources and kernel build packages and tools.
