Re: [Discuss-gnuradio] E100 frustrated newbie questions.

[Ingmar Meins]

Just so you don't think I gave up all disillusioned.

I have figured out how to change the GRC generated python files to not 
refer to the wx libraries, only takes a couple of lines to be edited. 
The result is that I can now create flowgraphs in grc on my development 
vm, copy the python file to the USRP E100, edit the couple of lines and 
my text based project works!

The proof of the pudding is a WBFM receiver that I just fired up and a 
couple of NBFM tx programs as well.

I did find a problem with the latest git gnuradio though, the UHD types 
are missing a _t at the end eg.

io_type = uhd.io_type.COMPLEX_FLOAT32 is generated by GRC but
io_type = uhd.io_type_t.COMPLEX_FLOAT32 is what is required to work...
