在 Ubuntu 虚拟机中使用 GNURadio:致命错误

using GNURadio in Ubuntu virtual machine: fatal error

我想在我的 Ubuntu 16.04 虚拟机上试用 GNURadio。我安装了 osmosdr 和 rtl-sdr,实际上我尝试了这两个源,但是我收到了这个错误:

Generating: '/home/natalia/Downloads/top_block_NoGUI.py'

Executing: /usr/bin/python -u 
/home/natalia/Downloads/top_block_NoGUI.py

Using Volk machine: avx2_64_mmx_orc
gr-osmosdr v0.1.4-98-gc653754d (0.1.5git) gnuradio 3.7.9
built-in source types: file fcd rtl_tcp rfspace redpitaya 

FATAL: No supported devices found to pick from.

Trying to fill up 1 missing channel(s) with null source(s).
This is being done to prevent the application from crashing
due to gnuradio bug #528.


>>> Done

我还以 root 身份创建了这个文件:/etc/udev/rules.d/20.rtlsdr.rules 其中包含以下行:

SUBSYSTEM=="usb", ATTRS{idVendor}=="0bda", 
ATTRS{idProduct}=="2838", GROUP="adm", MODE="0666", 
SYMLINK+="rtl_sdr

因为当我执行 lsusb 时,我得到:

我还能尝试什么?

您安装的 gr-osmosdr 没有 rtlsdr 支持; gr-osmosdr 给出的清单中不包含对 RTL 加密狗的本机支持。
