继续发问：关于Q_INVOKABLE引发的编译的问题。 [复制链接]

代码如下：
[doyle@phuang Q_INVOKABLE]$ cat q_invokable.h
#include <QObject>
#include <QMetaObject>
#include <QDebug>

namespace Type{

class Test : public QObject
{
   Q_OBJECT

   public:

      Q_INVOKABLE Test(): QObject( 0 ), _x( 0 ) {}

      Q_INVOKABLE void setX( int i ) { _x = i; }

      int foo() { return _x; }

   private:
      int _x;
};

};

[doyle@phuang Q_INVOKABLE]$ cat test_q_invokable.cpp
#include <QCoreApplication>
#include "q_invokable.h"

using namespace Type;

int main( int argc, char **argv )
{
    QCoreApplication app( argc, argv );

    const QMetaObject * obj = &(Test::staticMetaObject);

    Test *t = qobject_cast<Test *>(obj->newInstance());

    qDebug() << "foo = " << t->foo();
    QMetaObject::invokeMethod(t, "setX", Q_ARG( int, 42 ) );
    qDebug() << "foo = " << t->foo();

    return 0;
}

[doyle@phuang Q_INVOKABLE]$ make
g++ -c -pipe -O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fstack-protector --param=ssp-buffer-size=4 -m32 -march=i586 -mtune=generic -fasynchronous-unwind-tables -Wall -W -D_REENTRANT -DQT_NO_DEBUG -DQT_GUI_LIB -DQT_CORE_LIB -I/usr/lib/qt4/mkspecs/linux-g++ -I. -I/usr/include/QtCore -I/usr/include/QtGui -I/usr/include -I. -I. -o moc_q_invokable.o moc_q_invokable.cpp

make: *** [moc_q_invokable.o] Error 1

如果去掉命名空间Type或者在moc_q_invokable.cpp里面加上using namespace Type；，编译都可以顺利通过。

有人遇到过这个问题吗？有没有更好的解决办法？

const QMetaObject * obj = &(Test::staticMetaObject);
这句话改成
const QMetaObject * obj = &(Type::Test::staticMetaObject);

然后你再去掉using试试

还是不行，出错信息和之前一样。
