我在 qmake 文件中定义了 boost_program_options 。

> CONFIG(debug, debug|release) {
>     LIBS += -L"C:\boost_1_55_0\stage\lib" -lboost_program_options-mgw48-mt-d-1_55 -lboost_system-mgw48-mt-d-1_55 -lboost_thread-mgw48-mt-d-1_55 }

 CONFIG(release, debug|release) {
>     LIBS += -L"C:\boost_1_55_0\stage\lib" -lboost_program_options-mgw48-mt-1_55 -lboost_system-mgw48-mt-1_55 -lboost_thread-mgw48-mt-1_55 }

我想使用一个名为 mlpack 的库。并在mingw的帮助下编译。当我添加

"#include <mlpack/core.hpp>"

我有一些链接器错误（为了便于阅读，我粘贴了一些。）：

C:/Qt/Tools/QtCreator/bin/aubioSecond/libs//libmlpack.a(cli.cpp.obj):cli.cpp:(.text+0x3ed): undefined reference to `boost::program_options::options_description::m_default_line_length'

如果有人知道我为什么会遇到这个问题，我将非常感激。

Gilles Barges 在 mlpack 邮件列表中报告说，与 boost_program_options 的链接错误可以通过修改 CMakeLists.txt，第 189 行，注释掉该位来解决

set(Boost_LIBRARIES "")
