Question

我正在尝试使用Windows上的QT构建dlib提供的用于多类SVM培训的示例。（此链接提供了示例：http://dlib.net/multiclass_classification_ex.cpp.html）

首先，我使用MS visual studio从预建的库中获取了DLIB .lib文件，并将包含文件和修改后的QT .pro文件修改如下。

QT -= gui

CONFIG += c++11 console
CONFIG -= app_bundle

DEFINES += QT_DEPRECATED_WARNINGS
SOURCES += main.cpp

INCLUDEPATH += $$PWD/dlib/include
debug {
    LIBS += -L$$PWD/dlib/lib -ldlib_debug_64bit_msvc1900
}

!debug {
    LIBS += -L$$PWD/dlib/lib -ldlib_release_64bit_msvc1900
}

当我尝试构建代码时，我收到以下错误：

C:\Users\Administrator\Documents\SVMDlib\main.cpp:-1: error: undefined reference to `dlib::thread_pool_implementation::~thread_pool_implementation()'
C:\Users\Administrator\Documents\SVMDlib\main.cpp:-1: error: undefined reference to `dlib::thread_pool_implementation::shutdown_pool()'

C:\Users\Administrator\Documents\SVMDlib\main.cpp:-1: error: undefined reference to `dlib::thread_pool_implementation::~thread_pool_implementation()'
collect2.exe:-1: error: error: ld returned 1 exit status

知道我试图运行简单的SVM代码（在此提供：http://dlib.net/svm_ex.cpp.html），它编译并运行完美。

我错过了某种类型的图书馆吗？因为所有的错误都是链接错误和未定义的引用？

Windows下的DLIB和QT。 SVM多类培训无关联参考
