[Qemu-devel] Python problem

[Qemu-devel] Python problem

[Programmingkid]

After a 'git pull' on 9/12/2015, I noticed that QEMU no longer builds on Mac OS 10.6. I think there is a problem with a python script. This is the error message: 

  GEN   qmp-commands.h
Traceback (most recent call last):
  File "/scripts/qapi-commands.py", line 352, in <module>
    ret = gen_marshal_input(cmd['command'], arglist, ret_type, middle_mode) + "\n"

I'm using Python 2.6.1.

This issue has been reported multiple times:

https://lists.gnu.org/archive/html/qemu-devel/2015-09/msg02329.html

and the patch will hit the tree soon.

Excellent. This fixed the problem. Thank you very much. The minimum version of python QEMU
supports is 2.6?

At the moment it should be 2.4, apart from this bug. However we're about
to raise it to 2.6 (and there's a patch on the list that updates the
version check in configure). We were only retaining Python 2.4 support for
the benefit of RHEL5, and we stopped supporting RHEL5 in QEMU 2.5
when we raised our minimum glib version requirement.

thanks

This sounds like I need to add to the system requirements section of the documentation. 

Python 2.6 or higher is needed. Any other system requirements you think should be added
to QEMU's documentation.
