    Hi franku,

    You are right, but DEFINES qmake adds the values of this variable as compiler C preprocessor macros (-D option). So, when I add the line:
    @# interface_mngr.pro
    DEFINES +=
    INTERFACEMNGRLIB_LIBRARY@

    it add

    @#define INTERFACEMNGRLIB_LIBRARY@

    Thank you for your time.

    PD: When create shared lib follow this "link":http://doc.qt.nokia.com/4.7-snapshot/sharedlibrary.html#header-file-considerations

      Hi, I know. This is the reason why I asked you to rebuild your makefiles using qmake. Just to be shure having the -D commandline parameter being passed to the compiler. Read the contents of the link again carefully to see where the difference is to your code.

      You can use the #error to stop the preprocessor if you want to know which line is really evaluated.

      This, Jen, is the internet.

        I have found a strange issue:

        I delete all references to InterfaceMngr in the file core.h and core.cpp, and found that the library compile without errors, but when I try to use it, give the compile error referenced here before.

        BR,

          Shouldn't it be:

          @
          #if defined(INTERFACEMNGRLIB_LIBRARY)

          define INTERFACEMNGR_EXPORT Q_DECL_EXPORT

          #else

          define INTERFACEMNGR_EXPORT Q_DECL_IMPORT

          #endif
          @

          otherwise, INTERFACEMNGR_EXPORT will not be defined when you try to use the exported symbol.

            Hi Arnold,

            I have other two similars definitions but don't have any problem.
            The libraries "ModuleMngr":https://github.com/thanatosJSSE/Sipred/blob/master/src/managers/module/modulemngr.h and "PluginMngr":https://github.com/thanatosJSSE/Sipred/blob/master/src/managers/plugin/pluginmngr.h.

            Thank you.

              In both pluginmngr_global.h and modulmngr_global.h the declaration looks like this

              @
              #ifndef PLUGINMNGR_GLOBAL_H
              #define PLUGINMNGR_GLOBAL_H

              #include <QtCore/QtGlobal>

              #if defined(PLUGINMNGRLIB_LIBRARY)

              define PLUGINMNGR_EXPORT Q_DECL_EXPORT

              #else

              define PLUGINMNGR_EXPORT Q_DECL_IMPORT

              #endif

              #endif // PLUGINMNGR_GLOBAL_H
              @

              which is exactly what i suggested.

              Regards,
              Arnold

                If i am not wrong there is a missing ";" after Q_DECLARE_PRIVATE(InterfaceMngr):
                @
                private:
                Q_DECLARE_PRIVATE(InterfaceMngr) ; //here

                };
                @

                Never Seen !

                  That's right, interfacemngr have his own interfacemngr_global.h.

                  And this looks like you suggest.

                  BR,

                    There is no problem, I tried that too, without results.
                    I found that this library is compiled, but when I try to use it give me that error.

                      Ok,

                      Thank everyone that helped me to take a look to mi code.
                      Well the problem was a personal mistake:

                      @#if defined(INTERFACEMNGRLIB_LIBRARY)

                      define INTERFACEMNGR_EXPORT Q_DECL_EXPORT

                      #else

                      define INTERFACEMNGR_IMPORT Q_DECL_IMPORT <---- ERROR!!!

                      #endif@

                      Must be EXPORT like Arnold said

                      BR,
