嗨，我正在尝试使用 gnuplot-iostream，目前我只是想让代码在这里工作。当我尝试合并时，链接器中出现错误说：

In function `stream<int, boost::iostreams::file_descriptor_flags>':
/usr/include/boost/iostreams/stream.hpp:130: undefined reference to `boost::iostreams::file_descriptor_sink::file_descriptor_sink(int, boost::iostreams::file_descriptor_flags)'

In function `boost::iostreams::file_descriptor_sink boost::iostreams::detail::wrap<boost::iostreams::file_descriptor_sink>(boost::iostreams::file_descriptor_sink const&, boost::disable_if<boost::iostreams::is_std_io<boost::iostreams::file_descriptor_sink>, void>::type*)':
/usr/include/boost/iostreams/detail/wrap_unwrap.hpp:53: undefined reference to `boost::iostreams::file_descriptor_sink::file_descriptor_sink(boost::iostreams::file_descriptor_sink const&)'

In function `std::fpos<__mbstate_t> boost::iostreams::detail::seek_device_impl<boost::iostreams::any_tag>::seek<boost::iostreams::file_descriptor_sink>(boost::iostreams::file_descriptor_sink&, long, std::_Ios_Seekdir, std::_Ios_Openmode)':
/usr/include/boost/iostreams/seek.hpp:137: undefined reference to `boost::iostreams::file_descriptor::seek(long, std::_Ios_Seekdir)'
collect2: ld returned 1 exit status

注意我已经安装了 boost 并且以前编译过使用 iostream 的程序。任何帮助都非常感谢。谢谢

排除明显的......你在编译g++ -lboost_iostreams吗？如果您可以分享一些有关如何调用编译器和链接器的信息，它将更容易回答您的问题。

尝试将 g++ 与 gnuplot-iostream 库一起使用时遇到了确切的问题。

g++ prog.cpp -L/usr/lib -lboost_filesystem -lboost_system -lboost_iostreams

为我解决了这个问题 - 代码编译成功，没有错误。
