1、安装依赖

sudo apt-get install qt5-default
sudo apt-get install cmake
sudo apt-get install libbotan-2-dev
sudo apt-get install libqrencode-dev
sudo apt-get install libzbar-dev

2、编译libQtShadowsocks

wget https://github.com/shadowsocks/libQtShadowsocks/archive/v2.1.0.tar.gz
tar -xvf libQtShadowsocks-2.1.0.tar.gz
cd libQtShadowsocks-2.1.0
make build
cd build
cmake .. -DCMAKE_INATALL_PREFIX=/usr -DUSE_BOTAN2=ON
make -j4
make
sudo make install

3、编译shadowsocks-qt5

git clone https://github.com/shadowsocks/shadowsocks-qt5.git
cd shadowsocks-qt5
make build
cd build
cmake .. -DCMAKE_INATALL_PREFIX=/usr
make -j4
make

4、运行

ss-qt5

最近写了一个自动启动的QT程序，将程序及DLL都放到了同一个目录下。
双击启动，当然没有问题。
但设置为自动启动的时候，就提示找不到需要的DLL了。

最简单的方法，当然就是将DLL放到System32下面或者将DLL放到其他PATH的路径下面。
但我自己的环境已经够复杂了，实在是不想有其他冲突了。

于是，用VS写了一个启动用的Loader。
这个Loader啥都不干，就是先设置PATH，然后将参数传递给QT的EXE，启动之。

void MainWindow::initTimer()
{
    timer = new QTimer(this);
    connect(timer, SIGNAL(timeout()), this, SLOT(timerRecalc()));
    timer->start(1000*6);
}


void MainWindow::timerRecalc()
{
    for(int i=0;i<eventArray->size();i++)
    {
        NMyEvent myEvent = eventArray->at(i);
        ui->tableMain->setItem(i, 0, new QTableWidgetItem(myEvent.EventName));
        ui->tableMain->setItem(i, 1, new QTableWidgetItem(NMyUtils::formatDate(myEvent.TimeBegin)));
        ui->tableMain->setItem(i, 2, new QTableWidgetItem(NMyUtils::formatDate(myEvent.TimeDue)));
        myEvent.reCalcDaysLeft();
        ui->tableMain->setItem(i, 3, new QTableWidgetItem(myEvent.DaysLeft));
        ui->tableMain->setItem(i, 4, new QTableWidgetItem(myEvent.Comments));
    }
}

void MainWindow::readJson(QString fileName)
{
    QString szContent = NMyUtils::readFile(NMyUtils::getFileFullPath(fileName));

    QJsonDocument jDoc = QJsonDocument::fromJson(szContent.toUtf8());
    QJsonObject jObj = jDoc.object();
    QJsonArray jReminderItems = jObj.value(QString("Reminder")).toArray();

    foreach (const QJsonValue & item, jReminderItems)
    {
        QJsonValue eName = (item.toObject())["EventName"];
        QJsonValue tBegin = (item.toObject())["TimeBegin"];
        QJsonValue tDue = (item.toObject())["TimeDue"];
        QJsonValue comments = (item.toObject())["Comments"];
        const NMyEvent *myevent = NMyEvent::newEvent(eName.toString(),tBegin.toString(),tDue.toString(),comments.toString());

        eventArray->append(*myevent);
    }
}

void MainWindow::initTrayIcon()
{
    trayIcon=new QSystemTrayIcon(this);
    appIcon =new QIcon(NMyUtils::getFileFullPath("Reminder.png"));
    trayIcon->setIcon(*appIcon);
    this->setWindowIcon(*appIcon);

    autoStartAction = new QAction(tr("AutoStart"),this);
    autoStartAction->setCheckable(true);
    if(NMyUtils::isAutoStart())
    {
        autoStartAction->setChecked(true);
    }
    connect(autoStartAction, SIGNAL(triggered()), this, SLOT(autoStart()));
    showHideAction = new QAction(tr("Show"),this);
    showHideAction->setCheckable(true);
    showHideAction->setChecked(true);
    connect(showHideAction, SIGNAL(triggered()), this, SLOT(showHide()));
    quitAction = new QAction(tr("Quit"),this);
    connect(quitAction, SIGNAL(triggered()), qApp, SLOT(quit()));

    trayIconMenu = new QMenu(this);
    trayIconMenu->addAction(autoStartAction);
    trayIconMenu->addAction(showHideAction);
    trayIconMenu->addSeparator();
    trayIconMenu->addAction(quitAction);
    trayIcon->setContextMenu(trayIconMenu);

    trayIcon->setToolTip(tr("Reminder"));
    connect(trayIcon, SIGNAL(activated(QSystemTrayIcon::ActivationReason)), this, SLOT(iconActivated(QSystemTrayIcon::ActivationReason)));
    trayIcon->show();
}

最近整理了自己电脑上的源码，重新下载并编译了QT5的最新版本。
一开始还都顺利，后来就报错啦：

后来发现，是一开始的时候python没有正确的添加到路径之中，导致一个文件生成失败，从而引起的这个错误。
其解决方法如下：

1、查看文件%QT_HOME%\qtdeclarative\src\qmlRegExpJitTables.h，大小应该为0，删除该文件
2、确保可以执行python命令
3、重新nmake

此外，我的QT5编译环境配置文件如下：
