无法使用Qt（mingw32 x64）编译dlib

Question

我使用此代码工作了2天，我只是不知道如何通过此错误。 我用mingw32 x64编译dlib，一切正常，但是当我将库包含在qt的.pro文件中时，我会遇到很多错误。

这是我的专业文件：

QT       += core gui sql

greaterThan(QT_MAJOR_VERSION, 4): QT += widgets concurrent

QT += multimedia multimediawidgets network

CONFIG += c++11

TARGET = examinator

#    LIBS += "F:\examinator\dlib-19.10\build\install\lib\libdlib.a"
INCLUDEPATH += "F:\examinator\dlib-19.10\build\install\include"
LIBS +=-L"F:\examinator\dlib-19.10\build"
LIBS +=-ldlib

    LIBS += "C:\Program Files (x86)\libjpeg\lib\liblibjpeg.a"
    LIBS += "C:\Program Files (x86)\libpng\lib\libpng.a"
    LIBS += "C:\Program Files (x86)\libpng\lib\libpng16.a"

那是错误。

Answer 1

尝试将-L放在双引号中，并使用斜杠（而不是反斜杠）作为目录分隔符：

LIBS +="-LF:/examinator/dlib-19.10/build"

Answer 2

经过几次尝试，我发现了这些错误的来源，其中大多数是在我用CMake编译dlib时出现的，我也包含libpng，libjpg和zlib，但是在我的.pro文件中我没有正确包含它们。在正确包含它们之后，我便能够构建我的应用程序。

import GHC.Exts (IsList(..))

instance IsList XYZs where
  type Item XYZs = XYZ
  fromList = XYZs
  toList = getXYZs
