Many pieces of information are established when Qt is configured and built. This class provides an abstraction for accessing that information. By using the static functions of this class, an application can obtain information about the instance of the Qt library which the application is using at run-time. You can also use a \c qt.conf file to override the hard-coded paths that are compiled into the Qt library. For more information, see the \l {Using qt.conf} documentation. \sa QSysInfo, {Using qt.conf}*//*! \internal You cannot create a QLibraryInfo, instead only the static functions are available to query information.*/QLibraryInfo::QLibraryInfo(){ }#if defined(Q_CC_CLANG)// must be before GNU, because clang claims to be GNU too# define COMPILER_STRING __VERSION__/* already includes the compiler's name */#elif defined(Q_CC_GHS)# define COMPILER_STRING"GHS " QT_STRINGIFY(__GHS_VERSION_NUMBER)#elif defined(Q_CC_GNU)# define COMPILER_STRING"GCC " __VERSION__#elif defined(Q_CC_MSVC)# if _MSC_VER < 1910# define COMPILER_STRING"MSVC 2015"# elif _MSC_VER < 1917# define COMPILER_STRING"MSVC 2017"# elif _MSC_VER < 1930# define COMPILER_STRING"MSVC 2019"# elif _MSC_VER < 2000# define COMPILER_STRING"MSVC 2022"# else# define COMPILER_STRING"MSVC _MSC_VER " QT_STRINGIFY(_MSC_VER)# endif#else# define COMPILER_STRING"<unknown compiler>"#endif#ifdef QT_NO_DEBUG# define DEBUG_STRING" release"#else# define DEBUG_STRING" debug"#endif#ifdef QT_SHARED# define SHARED_STRING" shared (dynamic)"#else# define SHARED_STRING" static"#endifstatic const char*qt_build_string() noexcept {return"Qt " QT_VERSION_STR " (" ARCH_FULL SHARED_STRING DEBUG_STRING " build; by " COMPILER_STRING ")";}/*!
