[Qt-creator] Problems building with Qt Creator

[Tobias Hunger]

Hi João!


Please be aware that this mailing list is about developing Qt creator 
(not developing with Qt Creator:-). It would be appreciated, if you were 
to direct more generic Qt-related questions to the qt-interst mailing 
list instead.

These are linker errors: It fails to find the QtNetwork library (which 
contains the QTcpSocket class).

Don't trust the internet: Those suggestions are just voodoo and do not 
help with the issue:-)

Try changing
QT += core gui
to
QT += core gui network
in your .pro file instead.

Best Regards,
Tobias
