[Discuss-gnuradio] COST-TERRA examples need gnuradio from 'next' branch?

[Timo Juhani Lindfors]

Hi,

the "COST-TERRA Summer School, Dublin, Ireland" slides at
http://www.trondeau.com/gr-tutorial/ are great. Thanks a lot, Tom!

However, is it possible that some of the examples use features that are
only available in git? If I try

$ wget http://www.trondeau.com/storage/tutorial/mpsk_scripts_3_6.tar.gz
$ tar xf mpsk_scripts_3_6.tar.gz
$ mpsk_scripts_3_6/bits_representations.py

on my debian unstable chroot with gnuradio 3.6.1-1 I get

QGtkStyle was unable to detect the current GTK+ theme.
Traceback (most recent call last):
  File "mpsk_scripts_3_6/bits_representations.py", line 103, in <module>
    tb = bits_representations()
  File "mpsk_scripts_3_6/bits_representations.py", line 60, in __init__
    self.qtgui_const_sink_x_0 = qtgui.const_sink_c(
AttributeError: 'module' object has no attribute 'const_sink_c'

I looked around in git and noticed that
gr-qtgui/include/qtgui/const_sink_c.h exists only in the 'next' branch.

Am I missing something here or do the examples really need gnuradio from
git?
