Creating a DLL link library in Qt typically involves the following steps:<\/p>\n

    \n
  1. Add the following content to the .pro file to specify the generation of the DLL link library.<\/li>\n<\/ol>\n
    TEMPLATE = lib\r\nCONFIG += dll\r\nDEFINES += MYLIB_LIBRARY\r\n<\/code><\/pre>\n
      \n
    1. Write your class or function and place them in a separate class library project.<\/li>\n
    2. Export classes or functions in project header files using the Q_DECL_EXPORT macro.<\/li>\n<\/ol>\n
      class<\/span> Q_DECL_EXPORT<\/span> MyLibrary {\r\n    \/\/\u7c7b\u5b9a\u4e49<\/span>\r\n};\r\n<\/code><\/pre>\n
        \n
      1. To specify the generation of a DLL linkage library, add the following content in the .pro file:<\/li>\n<\/ol>\n
        INCLUDEPATH += $$PWD\r\nDEPENDPATH += $$PWD\r\nwin32 {\r\n    LIBS += -L$$OUT_PWD\/ -lMyLibrary\r\n}\r\n<\/code><\/pre>\n
          \n
        1. Compile the project to generate a DLL library file.<\/li>\n
        2. Import and use your classes or functions in other projects by using the generated DLL library file.<\/li>\n<\/ol>\n
          I hope these steps will be helpful for you!<\/p>\n","protected":false},"excerpt":{"rendered":"
