尝试安装rtl-sdr（通过git clone git://git.osmocom.org/rtl-sdr.git）感谢此处的说明，但不能比make第一个说明序列更进一步：
cd rtl-sdr/
mkdir build
cd build
cmake ../
make
在我第一次尝试时，我收到以下错误：
/rtl-sdr/src/librtlsdr.c:30:10: fatal error: libusb.h: No such file or directory
找到此文件后：
/usr/include$ sudo locate libusb.h
/usr/include/libusb-1.0/libusb.h
我试图#include <libusb.h>用#include <libusb-1.0/libusb.h>（如建议的here和here）替换原来的，这导致了不同的失败：

请注意，此建议似乎与我不知道在哪里找到的 gcc 编译选项/链接--cflags libusb-1.0或-lusb-1.0（参见此处和此处make）相关联（因为我正在使用，但不习惯）。
我还尝试#include <libusb.h>用（如此处#include <usb.h>所见）替换原来的，这导致：
/rtl-sdr/src/librtlsdr.c:97:2: error: unknown type name ‘libusb_context’
仅供参考libusb-1.0-0-dev并且libusb-dev已经安装（如建议here，我试过了，尽管我想我已经安装了它......）：
/usr/include$ sudo apt install libusb-1.0-0-dev
libusb-1.0-0-dev is already the newest version (2:1.0.21-2).
~$ sudo apt install libusb-dev
libusb-dev is already the newest version (2:0.1.12-31).
并且已经安装rtl-sdr使用apt：
sudo apt-get install rtl-sdr
rtl-sdr is already the newest version (0.5.3-13).
关于我的系统：Linux version 5.4.0-58-generic gcc version 7.5.0 (Ubuntu 7.5.0-3ubuntu1~18.04)。此安装旨在能够将 DVB-T 加密狗与 GNU Radio 一起使用，这需要此rtl-sdr安装。
编辑： @Tsyvarev 回答后
- 安装
pkg-config有sudo apt install pkg-config - 删除了由初始
git clone、新清理git clone、新/build等产生的第一个存储库，然后make，它起作用了！
删除旧的存储库克隆并重新创建一个干净是必要的，因为即使在安装后/build尝试make在旧版本中启动也不起作用。请注意，这意味着不需要对./buildpkg-config#include <libusb.h>src/librtlsdr.c
作为旁注，对于那些因为试图为 GNU Radio 安装“RTL-SDR Source”块而最终来到这里的人，我怀疑我的问题实际上是我在安装后没有安装gr-osmosdr一个sudo apt install gr-osmosdr简单rtl-sdr的sudo apt-get install rtl-sdr.
