QT 中的 moc 不会编译我的 c++头文件。说它太不同了
好吧,wtf 这是当我尝试 moc 我的头文件之一时 moc 告诉我的。我通过 Qt 4.5.3 命令提示符执行此操作,它说:
C:\Documents and Settings\The Fuzz\Desktop\GUI2>moc App_interface.h

有什么想法吗???我正在尝试使用 Q_OBJECT 宏。
ok wtf this is what moc tells me when i try to moc one of my header files. im doing this through Qt 4.5.3 command prompt and it says this:
C:\Documents and Settings\The Fuzz\Desktop\GUI2>moc App_interface.h

moc
将其输入标头转换为生成的文件,该文件打印在其输出上。您应该使用如下命令将其输出发送到文件:然后包含该文件。
如果您使用 QMake,我相信此过程是自动化的。
moc
converts its input header into a generated file, which is printed on its output. You should send its output to a file, with a command like:then include that.
If you're using QMake, I believe this process is automated.
这也可能有帮助:您需要在其他类之前从 QObject 继承: http://doc.trolltech.com/4.1/moc.html#multiple-inheritance-requires-qobject-to-be-first。
根据之前的回复,使用 qmake 更好。
我强烈建议使用 IDE Qt Creator,而不是从命令行构建。
This may also help: you need to inherit from QObject before other classes: http://doc.trolltech.com/4.1/moc.html#multiple-inheritance-requires-qobject-to-be-first.
As per the previous reply, it's much better to use qmake.
I'd strongly recommend using an IDE Qt Creator, rather than building from the command line.
