PRECOMPILED HEADERS无法使用Qt Creator/qmake/MinGw进行调试构建

在Qt Creator中,我有一个使用PRECOMPILED HEADERS的专业文件.

当我在Release模式下构建时,构建工作非常完美.但是在Debug模式下构建会产生错误,导致生成目标文件失败.例:

令人困惑的是它在Release中运行良好.我用一个小项目做了一些测试,它在Release或Debug模式下运行良好,但由于任何原因,一个更大的项目失败了.甚至不可能在Debug中编译项目的单个文件.专业档案如下:

QT += core gui \
    webkitwidgets \
    printsupport

greaterThan(QT_MAJOR_VERSION, 4): QT += widgets

TARGET = Euclide
TEMPLATE = app

QMAKE_CXXFLAGS += -std=gnu++11

CONFIG += precompile_header

# Use Precompiled headers (PCH)
PRECOMPILED_HEADER  = _pch.h    

SOURCES +=  main.cpp\
    mainwindow.cpp \
    zero.cpp \
    ... lot of files here...
    debug_tool.cpp

HEADERS += mainwindow.h \
    zero.h \
    ... lot of files here...
    debug_tool.h \
    _pch.h

FORMS += mainwindow.ui \
    zero.ui \
    ... other files...
    apphelp.ui \
    message.ui

INCLUDEPATH = "C:/Program Files (x86)/boost/boost_1_53_0"

LIBS += \
    ../build/release/exprcompiler.dll

RESOURCES += \
    resources/euclide_resources.qrc

我在网上花了几天时间来解决这个问题,但没有找到任何解释,即使有关qmake的文档已经完成......

有谁知道如何解决这个问题？因为我现在考虑的唯一解决方案是拥有这个所有项目的特殊"调试"版本,没有预编译头...感谢您的帮助.
