3D printing control software cura source code compiled on UbuntuKylin15.04

Cura versions on Linux are always downloaded and ready to be compiled from the source code.

The following is a compilation script downloaded from Https://github.com/ultimaker. There were some problems with the original script, and I made some changes, as follows:

#!/bin/bash# this is a script which get the latest git repo  and build them.## tested under ubuntu 15.04, lower versions  don ' T have pyqt 5.2.1 which is required by cura#cd ~mkdir  devcd devsudo apt-get install -y git cmake cmake-gui autoconf  libtool python3-setuptools curl python3-pyqt5.* python3-numpy  Qml-module-qtquick-controlsgit clone https://github.com/ultimaker/cura.gitgit clone https ://github.com/ultimaker/uranium.gitgit clone https://github.com/ultimaker/curaengine.gitgit  clone https://github.com/ultimaker/libarcusgit clone https://github.com/ultimaker/ Protobuf.gitecho build protobuf...cd protobuf./autogen.sh./configuremake -j4sudo make  installsudo ldconfigcd pythonpython3&nbSP;SETUP.PY BUILDSUDO PYTHON3 SETUP.PY INSTALLCD&NBSP, .... /..

Error compiling result:

Qwidget:must construct a qapplication before a qwidget./ubuntu-15.04-build-script.sh: line 62:29,168 has been discarded (core has been transferred Storage) Python3 cura_app.py

Who has done this, give directions.
