    Dear all:
    I'm new user on QT. Now I want to use function of class that name "QSerialPort", i can include the .h file and Qt Creator also recognize them, but when i compiled, I got faults. The content of fault is following:

    "LINK2019: unresolved external symbol "__declspec(dllimport)public: virtual _thiscall QSP::~QSerialPort(void)" (_imp??1QSerialPort@@UAE@XZ referenced in function _main"

    It seems is QT can't find the definition of function in "QSerialPort", my computer is 64-bit and compiler is "Microsoft Visual C++ Compiler 10.0(x86)", Qt version is "Qt 5.1.0(msvc2010) in my configuration, the QT I downloaded is 32-bit. Anyone has same problem ?? Or can someone give me some suggestions??
    Thanks.

      You need to tell Qt that you want to use the QSerialPort module. You can do this by adding the line

      QT += serialport

      to your .pro file.

      http://qt-project.org/doc/qt-5.1/qtserialport/qtserialport-index.html

      Good luck!
