Hi all,

is this related to the error message when calling configure:
./configure --prefix= --target-list=x86_64-softmmu --disable-vnc-png
--disable-vnc-jpeg --disable-vnc-tls --disable-vnc-sasl --audio-card-list=
--audio-drv-list= --enable-sdl --disable-xen --disable-brlapi
--disable-bluez --disable-nptl --disable-curl --disable-guest-agent
--disable-guest-base --disable-werror --disable-attr


Error: invalid trace backend
Please choose a supported trace backend.


When trying to press tab after typing --tra appending to the line above, I
get:

  File "/home/erik/qemu-test/qemu/scripts/tracetool.py", line 73
    except getopt.GetoptError as err:
                               ^
SyntaxError: invalid syntax
  File "/home/erik/qemu-test/qemu/scripts/tracetool.py", line 73
    except getopt.GetoptError as err:
                               ^
SyntaxError: invalid syntax

Any ideas?
My Debian 4.0 has Python 2.4.4.

Best regards,

Erik
