【问题描述】：
一些背景信息。
我有一个适用于两个平台/编译器的源代码库：
- Windows 10：MinGw：x86_64-8.1.0-posix-seh-rt_v6-rev0
- Raspberry PI 4/Linux：Raspberry-gcc8.3.0-r2
HostPc 适用于 Windows 10。
使用命令构建 BOOST Lib 后：
call bootstrap.bat mingw
call .\b2
这是构建结果：
The Boost C++ Libraries were successfully built!
The following directory should be added to compiler include paths:
:::::::::::::::::::::::\Boost_1_72_0
The following directory should be added to linker library paths:
:::::::::::::::::::::::\Boost_1_72_0\stage\lib
include 和 lib 路径是我的项目配置 (Windows/Raspberry) 的一部分。
此时可以使用 Boost-Lib 的功能。 例如：升压/asio 并且 TCP/IP 连接有效。
现在解决问题： 我想使用 BOOST Log 功能。
头文件：
#include <boost/log/trivial.hpp>
代码文件：
BOOST_LOG_TRIVIAL(info) << "This is an informational severity message";
链接器错误 (Windonws/MinGW) 看起来像：

其他一些帖子解释说这涉及静态和动态链接。我尝试了不同的方法都没有成功。

问题：如何解决 windows 配置的链接器错误？
-
问题：如何构建和链接 Boost 静态库，以便在一个地方拥有应用程序所需的所有功能。
-
问题：如何构建 Boost-lib，配置 MinGW（调用 bootstrap.bat mingw）和 GCC 同时在驱动器上？
提前谢谢 石质
更新
这个错误的根本原因是，我构建了错误的库： 对于 MinGW 案例（操作系统：Windows 架构：x84_64），主机也是目标。 所以用正确的配置构建 Boost 库的命令是：
call bootstrap.bat mingw
call .\b2 toolset=gcc target-os=windows --address-model=64 --link=static --variant=debug threading=multi --with-atomic --with-chrono --with-container --with-context --with-contract --with-coroutine --with-date_time --with-exception --with-fiber --with-filesystem --with-graph --with-graph_parallel --with-headers --with-iostreams --with-locale --with-log --with-math --with-mpi --with-program_options --with-python --with-random --with-regex --with-serialization --with-stacktrace --with-system --with-test --with-thread --with-timer --with-type_erasure --with-wave
应用程序部分的链接器命令应扩展为：
..\Boost_1_72_0\stage\lib\libboost_log-mgw81-mt-x64-1_72.a
..\Boost_1_72_0\stage\lib\libboost_thread-mgw81-mt-x64-1_72.a
谢谢
【问题讨论】：
-
显示您的链接器命令行，这肯定缺少 Boost Log 库。
-
你说得对，在第一篇文章的错误中，-
lboost_log标志不是链接器参数的一部分。如果我将此标志放在链接器的参数列表中，则该文件不存在：..\mingw-w64/x86_64-8.1.0-posix-seh-rt_v6-rev0/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/8.1.0/../../../../x86_64-w64-mingw32/bin/ld.exe: cannot find -lboost_log -
