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

    -DBUILD_SHARED_LIBS=ON ..

    I don't see how this should affect any code in e.g. https://github.com/EddyTheCo/Qpow-IOTA/blob/main/CMakeLists.txt apart from the naming of the library.

    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 .

              #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.

                            @Mesrine Take a look at the source code of any Qt module. You do the same thing.

                                When you build your lib, add target_compile_definitions(mysharedlib PRIVATE MYSHAREDLIB_LIBRARY). This means your lib exports these classes

                                MYSHAREDLIB_EXPORT

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

                                  @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 .

                                    @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 .
