Qemu: Could not open gdbserver on device 'tcp::1234'
I have installed qemu 0.14.1 on slackware to debug the linux-kernel. I am trying to connect with gdb to it through eclipse, but it just hangs. The commands I have tried are:
qemu -s -S -hda /dev/zero -kernel /home/jesse/build/linux-2.6.39/arch/x86/boot/bzImage qemu-system-x86_64 -s -S -hda /dev/zero -kernel /home/jesse/build/linux-2.6.39/arch/x86/boot/bzImage
With -S, qemu pauses on startup (as expected), and if i press ctrl+alt+2, i can then enter commands. When I enter gdbserver, or gdbserver tcp::1234 i get the error "Could not open gdbserver on device 'tcp::1234'. I also haven't been able to find any qemu logs or anything. If anyone knows how I can view logs, let me know.
I'm not sure what issue is causing gdbserver to fail to start. I am running Slackware 13.1 with a 64bit kernel in VirtualBox.

I believe the the command should be as follow on the target
gdbserver localhost:2345 myapp
On the host machine you will issue the following command
target remote <target ip address>:<port>
Hope that helps.
