make error: invalid conversion from ‘int’ to ‘bladerf_channel_layout'

[thesubtlety]

Running into an error while running make: error: invalid conversion from ‘int’ to ‘bladerf_channel_layout’. Any thoughts?

Running on Ubuntu 16.04 x64

I believe it's when they updated the libbladerf library to 2.0: https://nuand.com/libbladeRF-doc/v2.1.0/relnotes_2_0.html

I was able to compile LTE-Cell-Scanner with these changes I made:

I don't have a bladeRF to test but if this works for you be sure to let @JiaoXianjun or myself know so it can be merged!

That worked like a charm, appreciate the links and patch. Working successfully with a bladeRF x40.

[tonylambiris]

@JiaoXianjun would you like me to create a pull-request for this?

[tonylambiris]

@thesubtlety currently have a bladeRF 2.0 micro xA4 en route so I'll do some more testing once I get that in to figure out better default initialization values I've seen from other projects.
