    @Mesrine said in Shared library on windows fails when using moc:

    Cmake will let know the compiler that I want a shared library.

    ah, correct

    But you should add the correct defines then as described in the Qt documentation.

    I have tried but did not work either, maybe is another problem not related with the export macros.

    So if someone has been able to produce shared libraries on Windows while using MOC compiled sources it will be good to know how to do it in CMake.

      Then finally show us what you tried...

        @Mesrine It does not matter what you have done. You have to add MYSHAREDLIB_EXPORT into your class definition
        class MYSHAREDLIB_EXPORT MyClass

        But it does not exist in your classes.

        #include <QtCore/QtGlobal>

#if defined(MYSHAREDLIB_LIBRARY)  
# define MYSHAREDLIB_EXPORT Q_DECL_EXPORT
#else
#define MYSHAREDLIB_EXPORT Q_DECL_IMPORT
#endif

        When you build your lib, add target_compile_definitions(mysharedlib PRIVATE MYSHAREDLIB_LIBRARY). This means your lib exports these classes
        while MYSHAREDLIB_EXPORT=Q_DECL_EXPORT since MYSHAREDLIB_LIBRARY is defined.

        But in your main application, do not add it. However, the headers of all classes in your main application which use the lib have to have MYSHAREDLIB_EXPORT as well. That means these classes import the lib while MYSHAREDLIB_EXPORT=Q_DECL_IMPORT
        since MYSHAREDLIB_LIBRARY is not defined .

          @JoeCFD said in Shared library on windows fails when using moc:

          #if defined(_WIN32) || defined(WIN32)

          This is not needed and even counter-productive when you want to hide the symbols on linux.

            @Christian-Ehrlicher Got it, thanks. Q_DECL_EXPORT and Q_DECL_IMPORT have it already. But for non Qt code, this is needed.

              Even then I would use the correct attribution. Hiding the symbols by default on linux will help the linker and startup time and (iirc) also the optimizer in the linker since it can remove unused functions / inline stuff when it's not visible from outside.

                MYSHAREDLIB_LIBRARY

                Yes, I tried that and give the same error.

                Then my question is when should i define MYSHAREDLIB_LIBRARY in cmake?
                When compiling the library?
                If compiling the client should i set MYSHAREDLIB_LIBRARY?

                In my case compiling the client download the source code of the library and compile the source code.
                The target resulting from that shared library is linked to the client using cmake .

                Maybe i found my problem while writing this.
                I will do what Qt says(exactly :)) and try again, I llet you know the result and the code.

                Thanks.

                  And instead 'MYSHAREDLIB' you should use your library name...

                      @JoeCFD You have then compile with -fvisibility-inlines-hidden -fvisibility=hiddenand get the same behavior like the (default) windows behavior. See CMAKE_CXX_VISIBILITY_PRESET for more information on how to use it platform independent with cmake.

                              When you build your lib, add target_compile_definitions(mysharedlib PRIVATE MYSHAREDLIB_LIBRARY). This means your lib exports these classes
                              while MYSHAREDLIB_EXPORT=Q_DECL_EXPORT since MYSHAREDLIB_LIBRARY is defined.

                              But in your main application, do not add it. However, the headers of all classes in your main application which use the lib have to have MYSHAREDLIB_EXPORT as well. That means these classes import the lib while MYSHAREDLIB_EXPORT=Q_DECL_IMPORT
                              since MYSHAREDLIB_LIBRARY is not defined .

                                @JoeCFD said in Shared library on windows fails when using moc:

                                MYSHAREDLIB_EXPORT

                                But still i have to define MYSHAREDLIB_EXPORT to nothing if compiling in other system apart from windows?

                                @Mesrine Q_DECL_IMPORT and Q_DECL_EXPORT are hidden for example on Linux. No worries.

                                  Why? Simply use it as explained in the Qt documentation...

                                    Hi,

                                    You are over complicating things.

                                    As already suggested by @Christian-Ehrlicher, just follow the doc:

                                    • create one header with the macro definition as shown in the documentation
                                    • in your code include that header in all the classes you want to export and use the macro there
                                    • update your CMakeLists.txt as shown
                                    • rebuild

                                    And you should be good to go. There's really nothing more to it than that.

                                      @SGaist

                                      I tried on the shared library

                                      #include <QtCore/QtGlobal>

#if defined(MYSHAREDLIB_LIBRARY)
# define MYSHAREDLIB_EXPORT Q_DECL_EXPORT
#else
#define MYSHAREDLIB_EXPORT Q_DECL_IMPORT
#endif
namespace qiota{

	namespace qpow {


		class MYSHAREDLIB_EXPORT nonceFinder : public QObject
		{
			Q_OBJECT
			public:

                                      in the cmakelist.txt of the shared library

                                      add_library(qpow include/pow/qpow.hpp qpow.cpp)
target_compile_definitions(qpow PRIVATE MYSHAREDLIB_LIBRARY)

                                      As you can see on this commit
                                      This compiles the library in windows, linux, macos shared and static as before.

                                      I did the same for the client library as you can see for the
                                      comparison of the branch

                                      but this again fails for windows shared library as you can see form the workflow run with error

                                        cmake --build .

                                        @SGaist

                                        I tried on the shared library

                                        #include <QtCore/QtGlobal>

#if defined(MYSHAREDLIB_LIBRARY)
# define MYSHAREDLIB_EXPORT Q_DECL_EXPORT
#else
#define MYSHAREDLIB_EXPORT Q_DECL_IMPORT
#endif
namespace qiota{

	namespace qpow {


		class MYSHAREDLIB_EXPORT nonceFinder : public QObject
		{
			Q_OBJECT
			public:

                                        in the cmakelist.txt of the shared library

                                        add_library(qpow include/pow/qpow.hpp qpow.cpp)
target_compile_definitions(qpow PRIVATE MYSHAREDLIB_LIBRARY)

                                        As you can see on this commit
                                        This compiles the library in windows, linux, macos shared and static as before.

                                        I did the same for the client library as you can see for the
                                        comparison of the branch

                                        but this again fails for windows shared library as you can see form the workflow run with error

                                          cmake --build .

                                        I don't see the include of the generated moc file 'moc_qpow.h' in your code.
