qt如何调用linux库

// example.c
#include <stdio.h>

void exampleFunction() {
    printf("Hello from shared library!\n");
}

gcc -shared -o libexample.so example.c

// main.cpp
#include <QLibrary>
#include <QDebug>

typedef void (*ExampleFunction)();

int main(int argc, char *argv[]) {
    QCoreApplication app(argc, argv);

    QLibrary library("example");
    if (library.load()) {
        qDebug() << "Library loaded!";
        ExampleFunction exampleFunction = (ExampleFunction)library.resolve("exampleFunction");
        if (exampleFunction) {
            exampleFunction();
        } else {
            qDebug() << "Failed to resolve function!";
        }
    } else {
        qDebug() << "Failed to load library:" << library.errorString();
    }

    return app.exec();
}
