JUCE is an opensource crossplatform C application framework for desktop and mobile applications, including VST, VST3, AU, AUv3, RTAS and AAX audio plugins juceframework/JUCEIn this article A program that uses public symbols defined by a DLL is said to import them When you create header files for applications that use your DLLs to build with, use __declspec(dllimport) on the declarations of the public symbols The keyword __declspec(dllimport) works whether you export with def files or with the __declspec(dllexport) keyword__declspec(dllexport) const stdstring getHelloString(const stdstring & personName);

What is the utility of the keyword __declspec(dllimport), __declspec(dllexport)?Linux exports the whole public interface of the class by default Note 2 You should use Q_DECL_EXPORT and Q_DECL_IMPORT wrapped in the preprocessor ifdef (as in the link @SGaist sourced), so when including the headers from the user application/libarary you get the __declspec(dllimport) specifier, which is required for Windows(gcc/linux, solaris), there is no requirements to explicitly export symbols for shared objects, and I use the export attributes as a MSFT extension only when i compile with VS or VSintel

In this article In the case of data, using __declspec(dllimport) is a convenience item that removes a layer of indirection When you import data from a DLL, you still have to//testcpp #define DLLEXPORT extern "C" __declspec(dllexport) DLLEXPORT int sum(int a, int b) { return a b;Code in hpp is as below #ifdef EXPORT_MY_DLL

Jul 24, 15 · The compilers on Linux/UNIX have the ability to export all symbols in a shared library automatically On Windows, you must either use compiler directives __declspec(import) and __declspec(export) to declare which symbols are exported/imported from a shared library, or you must create a module definition text file (def) with a list of all the symbols you want to export#ifdef DLLDLL_EXPORTS #define DLLDLL_API __declspec(dllexport) #else #define DLLDLL_API __declspec(dllimport) but something that worked for me is to explicitely declare each member function as dllexport AFAIK you can remove the dllexport qualifier fromLearn more about `__declspec` In this article Microsoft Specific The extended attribute syntax for specifying storageclass information uses the __declspec keyword, which specifies that an instance of a given type is to be stored with a Microsoftspecific storageclass attribute listed below Examples of other storageclass modifiers include the static and extern keywords

Jul 04, 14 · Once the exported functions are identified, you can export from a DLL in two ways One is by using "def" file and another one is using the keyword "__declspec(dllexport)" You can use either one to export the functions from a DLL In this article I am using "__declspec(dllexport)" keyword to export the functions__declspec(dllexport) adds the export directive to the object file so you do not need to use a def file This convenience is most apparent when trying to export decorated C function names Because there is no standard specification for name decoration, the name of an exported function might change between compiler versions If you use __declspec(dllexport), recompiling the DLL and dependent# define MY_CLASS_API __declspec(dllexport) # else # define MY_CLASS_API __declspec(dllimport) # endif #else // no MSWindows, ignore # define MY_CLASS_API
