尝试在 QT 中编译项目时出现 Jom 错误

Question

我正在尝试运行我的项目，它设法构建但由于此编译错误而迅速终止。我正在为 windows kit 10、visual studio 14 和 directx 使用 64 位库。

    13:29:13: Running steps for project Phase64...
13:29:13: Configuration unchanged, skipping qmake step.

以前有人遇到过这个问题吗？

Answer 1

您的扩展日志显示 Qt 的 moc 在 ATL 标头上阻塞：

C:\Qt\5.6\msvc2015_64\bin\moc.exe -DUNICODE -DWIN32 -DWIN64 -DQT_QML_DEBUG -DQT_WIDGETS_LIB -DQT_GUI_LIB -DQT_CORE_LIB -D_MSC_VER=1900 -D_WIN32 -D_WIN64 -IC:/Qt/5.6/msvc2015_64/mkspecs/win32-msvc2015 -IC:/Users/Phenom/Documents/QT/Phase64 -I"C:/Program Files (x86)/Windows Kits/10/Include/10.0.10150.0/ucrt" -I"C:/Program Files (x86)/Microsoft Visual Studio 14.0/VC/include" -I"C:/Program Files (x86)/Microsoft DirectX SDK (February 2010)/Include" -I"C:/Program Files (x86)/Microsoft DirectX SDK (February 2010)/Include" -IC:/boost/boost_1_61_0 -I"C:/Program Files (x86)/Microsoft DirectX SDK (February 2010)/Include" -I"C:/Program Files (x86)/Windows Kits/10/Include" -I"C:/Program Files (x86)/Microsoft Visual Studio 14.0/VC/atlmfc/include" -IC:/Qt/5.6/msvc2015_64/include -IC:/Qt/5.6/msvc2015_64/include/QtWidgets -IC:/Qt/5.6/msvc2015_64/include/QtGui -IC:/Qt/5.6/msvc2015_64/include/QtANGLE -IC:/Qt/5.6/msvc2015_64/include/QtCore -I. ..\Phase64\mainwindow.h -o debug\moc_mainwindow.cpp
C:/Program Files (x86)/Microsoft Visual Studio 14.0/VC/atlmfc/include/atlbase.(3210): Parse error at "__identifier"

这意味着以下任何一种：

1. moc 无法处理 ATL 污点，在这种情况下，您需要向 Qt 寻求解决方案（例如，通过提交带有 !minimal! 示例代码的错误报告（例如，一个项目仅包含三个文件：main.cpp，some_qobject.h/.cpp，其中最后一个是你的..\Phase64\mainwindow.h/.cpp的完全还原）来重现这个。（报告它here）

   李>

2. 您在代码中弄乱了诸如__identifier 之类的宏/标识符，这些宏/标识符由实现保留。修复您的代码，使其不执行此操作。

3. Qt 的 moc 确实无法处理 ATL 标头。更改您的代码，使moced 文件不包含ATL 标头。 moc 定义了一个 Q_MOC_RUN 宏，因此您可以将 ATL 标头包装在 #ifndef Q_MOC_RUN...#endif 中，让 moc 忽略它们。

Answer 2

Qt 5.9.2 也有同样的问题。要至少暂时修复它，请将这行代码包含到 pro 文件中并运行 clean、qmake 并构建项目：

DEFINES += _ATL_NATIVE_INITIALIZATION

Answer 3

这似乎是 Qt 5.8 之后 moc 中已知的回归：https://bugreports.qt.io/browse/QTBUG-56634

报告声称修复已合并到 5.9.2，但我仍然看到问题。
