Hi！everybody,

How can I obtain I/Q samples using USRP N210 with a UBX daughterboard and a 3 dBi gain omnidirectional antenna?

I don't want to use Docker installation, I want to use CMake installation, but it always reports errors and prompts CMake error. Can you provide a CMake installation method? Thank you.

Error Msg：
CMake Error at swig/CMakeLists.txt:37 (include):
include could not find requested file:

GrSwig                                                        

CMake Error at swig/CMakeLists.txt:51 (GR_SWIG_MAKE):

Hi! Firstly, thank you for your work; it helped me understand LoRa PHY, and thanks for making the implementation public.
I followed the instructions to run gnuradio from the docker instance and faced an error, as seen in the attached image. When I try to run gnuradio from the shell, I run into this error.

Any help will be much appreciated; thanks!

EDIT: I figure the issue is caused by a misconfigured xterm on my local machine. I just had to correctly set the display variable for the GUI to work. For anyone facing a similar problem, the following commands helped:
$ sudo apt install xterm
$export DISPLAY=:0 xterm
