我如何使用boost与xeus-cling jupyter内核？

Question

我正在运行Pop!_OS (ubuntu导数)和apt从默认存储库安装的boost (libboost-all dev)。我知道它安装得很好，因为我可以用GCC编译并运行简单的boost odeint示例。

然而，当我试图在jupyter笔记本中使用zeus-cling内核运行相同的示例时，我在包含odeint标题时出错了。我可以在执行以下代码时重新创建错误：

#pragma cling add_include_path("/usr/include")
#include <boost/numeric/odeint.hpp>

我得到的错误消息是：

In file included from input_line_8:1:
In file included from /usr/include/boost/numeric/odeint.hpp:22:
In file included from /usr/include/boost/numeric/odeint/config.hpp:44:
In file included from /usr/include/boost/config.hpp:48:
In file included from /usr/include/boost/config/stdlib/libstdcpp3.hpp:78:
/usr/include/unistd.h:756:28: error: expected function body after function declarator
extern __pid_t fork (void) __THROWNL;
                           ^
/usr/include/unistd.h:869:11: fatal error: 'bits/getopt_posix.h' file not found
# include <bits/getopt_posix.h>
          ^~~~~~~~~~~~~~~~~~~~~
Interpreter Error: 

据我所知，bits/getopt_posix.h是GCC唯一的标题，因此我认为问题可能是因为boost头正在配置自己，就好像它们是在GCC下编译，而不是在clang/clang下编译。

那么，我该如何将boost恰当地包含在一本西埃夫斯-紧贴的笔记本里呢？

到目前为止，我一直在使用xeus(几何学)的boost (几何学)内核，没有任何问题。我安装从康达锻造(康达安装升压-c康达锻造)。我尝试将odeint.hpp包括在我的不稳定环境中，没有任何问题：

我走投无路，最终得到了解决我的问题的办法。

因此，我所做的是将boost超级项目作为子模块克隆到我的存储库中，然后添加使boost::numeric::odeint工作所需的所有包含路径。Odeint只是标题，所以它可以工作。这应该适用于所有的头只提升库。

我猜这不是正确的方法，但对我来说是可行的。只是为了以后的原型制作和小实验。

这是谐波振荡器的例子。
