expected body of lambda expression

tansgumus

Hi,

I'm working in integrating QML and C++ by applying this example but the parser says (unable to build the project too):

error: expected body of lambda expression // points to  emit [ emit]  userNameChanged();

Although I already included CONFIG += c++11 in my .pro file!

How can I fix this issue?

OS: Linux Mint 19.1 xfce
GCC: gcc (Ubuntu 7.3.0-27ubuntu1~18.04) 7.3.0
G++: g++ (Ubuntu 7.3.0-27ubuntu1~18.04) 7.3.0

Hi
Can you show the actual code that gives this error?
Looking at sample

void BackEnd::setUserName(const QString &userName)
{
    if (userName == m_userName)
        return;

    m_userName = userName;
    emit userNameChanged();
}

I see no lambdas or any cause for such error.

silly me. I was playing with lambda so I forgot to remove the code.

@tansgumus
ah, so the [] part was left and
it missed the actual body ? ( {})
Well these things happens :)
