Hey
Based on an idea by Ulrich Weigand, I've uploaded a new gdb to natty
today which adds a gdb-multiarch binary package. It's about 19 MB and
once you install it, you will get a new /usr/bin/gdb-multiarch which
can debug any target that gdb knows about, including ARM!
So you could debug an ARM "/bin/ls" from a local chroot with
qemu-arm-static by running gdb-multiarch and then running:
(gdb) file /arm-chroot/bin/ls
"/arm-chroot/bin/ls": not in executable format: File format is ambiguous.
Matching formats: elf32-littlearm elf32-littlearm-symbian
elf32-littlearm-vxworks.
Use "set gnutarget format-name" to specify the format.
(gdb) set gnutarget elf32-littlearm
(gdb) file /arm-chroot/bin/ls
In the chroot, run:
qemu-arm-static -g 1234 /bin/ls
and in gdb-multiarch:
target remote localhost:1234
and you can now use gdb as usual, setting breakpoints, single-stepping
etc.
(It obviously also works with remote debugging of a real,
network-connected ARM board; use gdbserver instead of qemu)
Would people be interested in backports?
Cheers,
PS: the package is in NEW and will show up soon in natty; in the mean
time, you can get it from my natty PPA:
