Qt5.5已經發布了,前兩天PyQt也很快推出了一個5.5的對應版本。試驗了一下(花了個週末啊!),真是愈來愈好用了。Qt5.5在Ubuntu15.04上有一些重要的改進,在虛擬機裏運行的窗口覆蓋問題也終於沒有了。由於要裝好幾個軟件,挺花功夫的。這裏給出個腳本,能夠快速安裝。python
首先安裝Qt5.5。linux
#在線安裝用這個. wget http://download.qt.io/official_releases/online_installers/qt-unified-linux-x64-online.run chmod +x qt-unified-linux-x64-online.run ./qt-unified-linux-x64-online.run #離線安裝用這個. wget http://download.qt.io/official_releases/qt/5.5/5.5.0/qt-opensource-linux-x64-5.5.0-2.run chmod +x qt-opensource-linux-x64-5.5.0-2.run ./qt-opensource-linux-x64-5.5.0-2.run
而後,設置一下Qt的路徑。shell
#Add Qt Path to /etc/profile. sudo gedit /etc/profile #add line: export PATH=$PATH:/home/userXXX/Qt/Qt5.5/gcc_64/bin
通常新裝的系統須要安裝OpenGL的支持。ui
sudo apt-get install libgl1-mesa-dev
注意:目前的Qt5.5版本的在線安裝版本中將「Open Source」標示爲了「Builder Qt」,致使PyQt中判斷錯誤,拋出許可不兼容的錯誤。將PyQt目錄中的configure.py添加以下行(搜索Common checks,2590行處),從新編譯便可。離線安裝的Qt5.5貌似沒有這個問題。spa
# Common checks. #change by openthings@163.com. print("License:") print(introspecting) print(target_config.qt_licensee) print(ltype) target_config.qt_licensee = 'Open Source' #end change.
下面是完整的腳本:

Qt+Python已經開始成爲不少系統級軟件的標配了,Qt5.5的發佈改掉了之前的不少小毛病,基本上能夠放心地使用了。
