构建 CXX 对象 gnuradio-runtime 时出错

Question

我正在尝试安装特定版本的 gnuradio (3.7.10.1)。为此，我没有使用 Pybombs，但我尝试从源代码开始（我关注 this）。

首先我克隆了 github 存储库，然后签出适当的版本。在我尝试调用 CMake 并构建 GNU Radio 之前，它运行良好：

mkdir build
cd build
cmake ../
make

在 make 中，完成 6% 后，出现以下错误：

我不是 Linux 专家，我对这个编译器/库支持不是很熟悉。我真的不明白错误来自哪里以及如何纠正它。 我使用的是 Ubuntu 18.04。

你能帮我解决这个问题吗？ 任何帮助将不胜感激。 非常感谢。

/usr/include/c++/7/bits/c++0x_warning.h:32:2: error: #error 此文件需要编译器和库支持 ISO C++ 2011 标准。必须使用 -std=c++11 或 -std=gnu++11 编译器选项启用此支持。

要解决上述错误，您需要使用-std=c++11 标志进行编译。打开CMakeLists.txt，找到所有匹配项或-std=c++98，并将它们更改为-std=c++11。然后进入build目录，删除CMakeCache.txt并重建

sed -i 's/-std=c++98/-std=c++11/g' CMakeLists.txt
cd build
rm CMakeCache.txt
cmake ..
make

由于错误出现在 cppunit 中并且它用于测试，您可以尝试禁用所有测试

cd build
rm CMakeCache.txt
cmake -DENABLE_TESTING=OFF ..
make
