提升链接错误

Question

所以,我正在尝试使用boost.process库.我从这个位置下载了包,复制包含从boost子目录到/ usr/include/boost,写了一个简单的代码:

    namespace bp = ::boost::process;
    std::string execApp = "make";
    std::vector<std::string> args;
    args.push_back("-C ../build");

    bp::context ctx;
    ctx.stdout_behavior = bp::silence_stream();

    bp::child buildProcess = bp::launch(execApp, args, ctx);

它编译但链接器失败:

/usr/include/boost/system/error_code.hpp:208: undefined reference to `boost::system::get_system_category()'

我已经链接了这样的库: filesystem system date_time

你可能想在这里看到最后的答案.

我有一个非常相似的问题,在搜索时发现了这篇文章.经过更多的搜索,我设法解决了这个问题,所以我在这里发布给其他人.

我必须以这种方式链接到正确的库:g ++ boost_example.cpp -o run -lboost_filesystem-mt http://linux.overshoot.tv/ticket/127

真正的问题是缺少boost文档,并没有说要链接到哪个库.请参阅:http: //linux.overshoot.tv/ticket/129

无论如何,要使用boost/file_system,请链接到:-lboost_filesystem-mt.
