        Yes, i use the old api in static mode, this api is writing for build shared library, look the macro
        @

        define QEXTSERIALPORT_EXPORT Q_DECL_EXPORT

        @ in the code

          Where is that definition?, i have never tried to link statically, but in the "qextserialport.pro" there is a line that says: #CONFIG += staticlib, have you tried to uncomment it?, and then compile it again( qmake, make)....

            Yes, but many error give to me.
            That line is in the class QextSerialEnumerator
            @
            class QEXTSERIALPORT_EXPORT QextSerialEnumerator : public QObject@

              mmm Maybe i have a differente version, because the QextSerialEnumerator doenst inherit from QObject:

                    The same of me, but you download it from sourceforge, me from googlecode.
                    Now i trying your lib, this not build a dll but the code you post don't display any port.
                    The same code work well in googlecode library with a dll.

                      I've used QSerialDevice to great success for other serial port tasks, it may be worth a look.

                          Yes, i also use this library with success. But i think the 'enumeration' feature is in a very alpha state.
                          Only with a dll i can run correctly this feature.
