【问题描述】：

我已经尝试安装 gr-osmosdr 很长一段时间了，但我从来没有结束安装过程。我已按照https://github.com/osmocom/gr-osmosdr 上的步骤进行操作它展示了如何通过 cmake 安装 gr-osmosdr。在克隆和构建“build”目录之后，是时候让 cmake 完成它的工作了。正是在这一步，事情开始失败。我收到以下错误：

CMake Warning (dev) at /home/victor/.local/lib/python2.7/site-packages/cmake/data/share/cmake-3.18/Modules/GNUInstallDirs.cmake:225 (message):

CMake Error at CMakeLists.txt:44 (find_package):
  Could not find a configuration file for package "Gnuradio" that is
  compatible with requested version "3.8".

  The following configuration files were considered but not accepted:

    /usr/lib/x86_64-linux-gnu/cmake/gnuradio/GnuradioConfig.cmake, version: 3.7.9.1

此时我无法继续安装过程。我正在运行 Ubuntu 16.04.7 LTS 和 GNU Radio 3.7.9。 谢谢

【解决方案1】：

错误消息非常具有描述性：您正在尝试使用 ancient GNU Radio 3.7.9.1 构建与现代 GNU Radio 3.8 兼容的 gr-osmosdr。不会工作。您可以尝试构建一个过时版本的 gr-osmosdr，但实际上，您应该升级到 Ubuntu 20.04。

在那里，你可以

sudo apt install gnuradio gr-osmosdr

并且不必自己构建任何东西（它会工作！）。
