我正在尝试构建Doge硬币无头钱包（类似于bitcoind）它似乎是Boost导致错误，但我不知道如何解决它。
（Ubuntu 12.04）
当我执行“make -f makefile.unix USE_UPNP = - ”时，我收到此错误：

您需要链接这些boost库，即将-lboost_thread -lboost_filesystem -lboost_system添加到链接器命令行。
有关详细信息，请参阅Link Your Program to a Boost Library。

我遇到了同样的问题，使用了boost 1.55.0。
我在boost库上使用了nm，没有包含任何包含filesystem3的符号
我假设boost 1.55.0删除了filesystem3，可能只将其放入标题模板，但这只是猜测。我正在链接mongodbclient.a并且我不想从源代码重新编译mongo（需要大量的设置）
转向提升1.49.0解决了问题。这些库中包含了filesystem3。

使用boost 1.62我遇到了同样的问题。
但是，在我的情况下，因为我在我的Ubuntu 16.04上安装了几个boost版本，所以将库和include目录指向正确的文件夹确实有帮助。
我为include文件夹和库文件夹创建了符号链接（通过boost安装自动完成）：
/ usr / include / boost - ＆gt;的/ usr /本地/ boost_1_62_0 /升压
和
/usr/local/lib/libboost_thread.so - ＆gt; libboost_thread.so.1.62.0
答案 3 :(得分：0)
如果您确定链接器被赋予了-lboost_...标志（请参见Maxim Egorushkin's答案），但是您仍然遇到链接器错误，则需要检查其他几件事：
如果您正在使用或已经在系统上使用多个版本的boost，则可能要针对的头文件和要针对的链接库之间存在版本差异。您将需要通过运行libboost_*.so来检查您的ls -l your_lib_path/lib/libboost_*.so符号链接所链接的版本。如果这些符号链接未指向所需的Boost版本，则可以修改链接。
您可能还想将boost安装在与其他库分开的唯一位置，以确保版本一致性。如果这样做，请确保将新路径 first 放在您的LD_LIBRARY_PATH中，并为GCC提供新的-I包含路径标记（也应放在第一位）。
尤其是如果您使用的是Boost的定制版本，则在尝试构建和链接库时，将要确保使用正确的预处理器定义（-D标志）。例如，在标题boost/thread/pthread/header_data.hpp中：
#ifdef BOOST_THREAD_USES_CHRONO
#ifdef BOOST_THREAD_SLEEP_FOR_IS_STEADY
inline
void BOOST_SYMBOL_VISIBLE sleep_for(const chrono::nanoseconds& ns)
{
return boost::this_thread::hiden::sleep_for(boost::detail::to_timespec(ns));
}
#endif
#endif // BOOST_THREAD_USES_CHRONO
如果库是在没有BOOST_THREAD_USES_CHRONO的情况下构建的，则功能void BOOST_SYMBOL_VISIBLE sleep_for(const chrono::nanoseconds& ns)将不在共享库中。如果要使用BOOST_THREAD_USES_CHRONO定义的 增强库进行构建，最终可能会出现链接器错误。
