Qt应用在Linux下的部署

我正试图在Ubuntu下部署我的qt应用程序。 我有Qt5.1.1。库是动态链接的

大体上

QStringList paths = QCoreApplication::libraryPaths();
paths.append("libs");
paths.append("platform");
paths.append("audio");
paths.append("designer");
paths.append("sqldrivers");
QCoreApplication::setLibraryPaths(paths);

但当我尝试运行应用程序时，我得到：

加载共享库时出错：libQt5WebKitWidgets.so.5:无法打开共享对象文件：没有这样的文件或目录

我不确定，但可能您不仅应该附加目录名，还应该附加完整路径。获取应用程序目录，并将子目录名称附加到其中

QString appFilePath = QCoreApplication::applicationFilePath();

QStringList paths = QCoreApplication::libraryPaths();
paths.append(QString("%1/%2").arg(appFilePath).arg("libs"));
paths.append(QString("%1/%2").arg(appFilePath).arg("platform"));
...

要使用QCoreApplication函数applicationFilePath，我需要创建QApplication的实例，否则它将返回一个空字符串。但若我试图创建QApplication对象，它会抛出我发布的错误。我建议您阅读一些关于Debian中包的内容。在这个包中，您应该定义包依赖项，这样Debian将与您的包一起安装其他所需的库。考虑使用不同的构建管理器，请参阅本页哦，我知道有关包的信息。不过，qt应用程序需要一些文件才能与libQt5*.so一起显示。谢谢你的链接
