The goal of this series is to remove Avocado as a dependency for running
the reverse_debugging functional test.
After several rounds of discussions about v1 and v2, and experiments
done by Daniel and Thomas (thanks for all the experiments and comments
so far), I've taken a new approach and moved away from using a runner
for GDB. The changes, I believe, are much simpler now.
Hi Gustavo,
unfortunately, this still seems to be broken on Fedora. After applying
your series, I get:
stderr:
Traceback (most recent call last):

Looks like it's required to explicitly use the --gdb=... parameter of
configure to make it work, and it does not work without that paramter?
Could you please have a look whether it works without --gdb with the
auto-detected gdb for you?
...
I've just tried it on Fedora 42 and GDB is correctly detected:
$ ../configure --target-list=aarch64-softmmu --disable-docs
> $ make -j check-functional-aarch64
I just tried it again, and it just seems to be broken in my build folder
where I do incremental builds. It works when I build QEMU in a new folder
from scratch - quite weird.
I have installed:
gromero@gromero13:~/git/qemu/build$ dnf info gdb
Updating and loading repositories:
Repositories loaded.
Installed packages

I've got the very same package installed here.
Are you sure GDB is installed in your test env?
Do mind checking if:
gromero@gromero0:/mnt/git/qemu_$ gdb_bin=$(command -v "gdb-multiarch" ||
command -v "gdb")
gromero@gromero0:/mnt/git/qemu_$ echo $gdb_bin
/usr/bin/gdb
works in your env and if QEMU_TEST_GDB is in:
$ ./pyvenv/bin/meson test --verbose --no-rebuild -t 1 --setup thorough
--suite func-thorough func-aarch64-reverse_debug
output?
$ echo $gdb_bin
/usr/bin/gdb
