Re: [Discuss-gnuradio] Error in python (XML file)

[Zohair]

Hi Josh,

Thanks for replying.

I tried what you told me to do. I added %include<usrp2/usrp2.h> and maked
the directory. However, I receive this error;

usrp2.cc: In function ‘PyObject* _wrap_usrp2_start_rx_streaming(PyObject*,
PyObject*, PyObject*)’:
usrp2.cc:7970: error: ‘time_spec_t’ was not declared in this scope

This line has: 
  usrp2::time_spec_t const &arg3_defvalue = time_spec_t() ;

Before this line there are a lot of occurrences of time_spec_t and there is
no compiling error. This means that the usrp2.h is indeed accessed but why
do you think I receive this error? Any clue or hint, please?

Cheers,
Zohair
