Why this doesn't work? qDebug() << "Test" << std::endl;

[high_flyer]

why do you think this should work in the first place?

[lsvichet]

just write

qDebug()<<"Test";

don't forget to include: #include <QDebug>

You should know that: std::endl is just a template function

declaration:

template <class charT, class traits>
basic_ostream<charT,traits>& endl ( basic_ostream<charT,traits>& os );

and following code is equal:

std::cout<<"hello"<<std::endl;
std::endl(std::cout<<"hello");

std::endl is not supported by qDebug() (QDebug (http://doc.qt.nokia.com/latest/qdebug.html)). This is not a STL stream!
Every qDebug() << somthig << something; creates log in separate line.
