Hey guys,

I started to have this with the git master and uhd from yesterday evening:

linux; GNU C++ version 4.6.0 20110415 (prerelease); Boost_104600; 


ub/grotarapi/PHY/PhysicalLayer.py", line 47, in __init__
    self.u_tx = uhd.usrp_sink(hint, io_type=uhd.io_type_t.COMPLEX_FLOAT32, 
  File "/usr/lib/python2.7/site-packages/gnuradio/uhd/__init__.py", line 73, in 
    if kwargs.has_key(key): kwargs[key] = cast(kwargs[key])
  File "/usr/lib/python2.7/site-packages/gnuradio/uhd/uhd_swig.py", line 409, 
in __init__
    this = _uhd_swig.new_io_type_t(*args)
NotImplementedError: Wrong number or type of arguments for overloaded function 
  Possible C/C++ prototypes are:


If I try the same with a size_t instead (in bpython):

a = uhd.usrp_sink(device_addr='type=usrp2', io_type=32, num_channels=1)
# OUT: Traceback (most recent call last):
# OUT:   File "<input>", line 1, in <module>
# OUT:   File
# "/usr/lib/python2.7/site-packages/gnuradio/uhd/__init__.py", line 74,
# in constructor_interceptor
# OUT:     return old_constructor(*args, **kwargs)
# OUT:   File
# "/usr/lib/python2.7/site-packages/gnuradio/uhd/uhd_swig.py", line
# 1854, in usrp_sink
# OUT:     return _uhd_swig.usrp_sink(*args, **kwargs)
# OUT: RuntimeError: gr_io_signature(3)

Any hints how to fix this? Did someone already see something like this?
I think it might be somehow related to 7787d1fc1aecc7b59e476c31865b4f32348cb729 

All the best,
