c++ - Qt5.2 NetworkManager::networkInterfaces()

Question

我正在尝试编译一个简单的 Qt5.2 程序，它使用 libnm-qt5 和 libmm-qt5 来管理连接，但是当我试图用这段代码列出它们时:

#include <arpa/inet.h>

#include <QtCore/QTextStream>

#include <NetworkManagerQt5/manager.h>
#include <NetworkManagerQt5/device.h>
#include <NetworkManagerQt5/activeconnection.h>
#include <NetworkManagerQt5/connection.h>

QString typeAsString(const int type)
{
    switch (type) {
    case 0x0: return QString("Unknown");
    case 0x1: return QString("Ethernet");
    case 0x2: return QString("Wifi");
    case 0x3: return QString("Unused1");
    case 0x4: return QString("Unused2");
    case 0x5: return QString("Bluetooth");
    case 0x6: return QString("OlpcMesh");
    case 0x7: return QString("Wimax");
    case 0x8: return QString("Modem");
    }
    return QString("Unknown");
}

int main()
{
    QTextStream qout(stdout, QIODevice::WriteOnly);

    NetworkManager::Device::List list = NetworkManager::networkInterfaces();

    foreach (NetworkManager::Device *dev, list) {
        qout << dev->uni() << "\n";

我在 QtCreator 中遇到错误:“/home/me/Qt/5.2.1/gcc_64/include/QtCore/qglobal.h:860: error: cannot convert 'const QSharedPointer' to 'NetworkManager::Device* ' 在初始化中 for (variable = *container.i;; extension ({--container.brk; break;})) ^”

我一直在像 tis 这样的存储库中搜索:https://build.merproject.org/package/view_file?file=enable-contour.patch&package=plasma-mobile&project=home%3Awonko%3Apa-devel-contour-hack&rev=21他们使用:

NetworkManager::Device::List iflist = NetworkManager::networkInterfaces();
    foreach (NetworkManager::Device::Ptr iface, iflist){

}

但它也给我错误。有谁知道正确的解决方案？

谢谢。

尝试替换

foreach (NetworkManager::Device *dev, list) { ... 

用这个:

foreach (NetworkManager::Device::ptr dev, list) { ...
