QNetworkInterface intr = session.interface();

Is it a typo? Should be int not intr.

[ODБOï]

@jsulm i named it 'intr' for 'interface'

[jsulm]

@LeLev Forget my comment, somehow I managed to read this line in a wrong way :-)

[Ratzz]

@LeLev
Error with QNetworkSession::interface():

Do you have a macro in rpc.h called "interface"?

Can you check this ?

[ODБOï]

@Ratzz yes, there is

#include <_mingw.h>

#ifndef __OBJC__
#undef interface
#define interface struct
#endif

in my C:\Qt\Tools\mingw730_64\x86_64-w64-mingw32\include

[ODБOï]

This solved the probleme

    QNetworkSession session ( conf );
    #undef interface
    QNetworkInterface intr = session.interface();

Thank you @jsulm and @Ratzz

[jsulm]

@LeLev This is strange. You're not building for MacOS.

__OBJC__

is defined when building for MacOS, see https://stackoverflow.com/questions/2054669/objc-in-objective-c

[ODБOï]

@jsulm yes i'm building for windows.

[jsulm]

@LeLev Do you have anything related to MacOS in your pro file?

[ODБOï]

@jsulm no, nothing
