This is my first message, I am writing to you, because this time I can’t really get away from this problem.
I am taking a course on gdb. In subsequent lessons, the course covers debugging the ARM architecture, so I’m presented with a setting that allows me to emulate this situation.
My current setup consists of:
- Windows 10: physical host
- Ubuntu 12.04.5 LTS: guest OS via Oracle Virtual Box in Windows 10
- Linux debian-armel 2.6.32-5-universal: guest os via qemu 2.8.0 on Ubuntu
The ARM Debian image comes from https://people.debian.org/~aurel32/qemu/armel/
Image is launched using
qemu-system-arm -M versatilepb -kernel vmlinuz-2.6.32-5-versatile -initrd initrd.img-2.6.32-5-versatile -hda debian_squeeze_armel_standard.qcow2 -append "root=/dev/sda1" -m 256 -redir tcp:2222::22
I changed sources.list and apt.conf so that apt works as the distribution is pretty outdated. I updated and updated and installed gcc and gdb.
The problem occurs when trying to debug: I can load executables in gdb
root@debian-armel :~/video-11/video-11
but when I try to run it inside gdb, I get this message and execution freezes until I can kill the gdb process from another console

Can someone point me in a direction to solve this problem?
Thanks in advance!
