接下来,在主项目中加载并调用该动态库。 #include <QLibrary> #include <QDebug> typedef void (*MyFunctionType)(); int main(int argc, char *argv[]) { QApplication app(argc, argv); QLibrary mylib("mylib"); if (!mylib.load()) { qDebug() << "Failed to load the library"; return ...
#include <QLibrary> #include <QDebug> int main(int argc, char *argv[]) { QCoreApplication a(argc, argv); // 动态加载DLL库 QLibrary myLib("mylibrary.dll"); // 替换为你自己的DLL库文件名 // 检查是否成功加载 if (!myLib.load()) { qCritical() << "Failed to load DLL library:"...
对于调用DLL的方法，Qt原来本身就有相应的类来实现，用起来和Win32的步骤差不多。下面是代码，已经编译通过。在控制台依次输入qmake –project、qmake、 nmake，即可。include include include //动态链接不需要包含LTM8000D.h头文件 typedef int ( *pcom_open)(int , int , int ); //定义函数指针...
