Cura在Linux上的版本总是下载不了，准备自己从源码进行编译。
下面是从 https://github.com/ultimaker 上下载的编译脚本。原始的脚本有一些问题，自己做了一些修改，如下：
#!/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 ~ if [ ! -d "cura_dev" ]; then mkdir cura_dev fi cd cura_dev sudo apt-get install -y git cmake cmake-gui autoconf libtool python3-setuptools curl python3-pyqt5.* python3-numpy qml-module-qtquick-controls git clone https://github.com/Ultimaker/Cura.git git clone https://github.com/Ultimaker/Uranium.git git clone https://github.com/Ultimaker/CuraEngine.git git clone https://github.com/Ultimaker/libArcus git clone https://github.com/Ultimaker/protobuf.git cd protobuf ./autogen.sh ./configure make -j4 sudo make install sudo ldconfig cd python python3 setup.py build sudo python3 setup.py install cd ../.. cd libArcus if [ ! -d "build" ]; then mkdir build fi cd build cmake .. -DPYTHON_SITE_PACKAGES_DIR=/usr/lib/python3.4/dist-packages make -j4 sudo make install cd ../../ cd CuraEngine if [ ! -d "build" ]; then mkdir build fi cd build cmake .. make -j4 cd ../../ cd Uranium if [ ! -d "build" ]; then mkdir build fi cd build cmake .. -DPYTHON_SITE_PACKAGES_DIR=/usr/lib/python3.4/dist-packages -DURANIUM_PLUGINS_DIR=/usr/lib/python3.4/dist-packages sudo make install cd ../.. cp -rv Uranium/resources/* Cura/resources/ sudo ln -s $PWD/CuraEngine/build/CuraEngine /usr/bin/CuraEngine cd Cura python3 cura_app.py #export PYTHONPATH=/usr/lib/python3/dist-packages
运行了很长时间，但结果不太妙啊。
编译结果出错： QWidget: Must construct a QApplication before a QWidget ./ubuntu-15.04-build-script.sh: 行 62: 29168 已放弃 (核心已转储) python3 cura_app.py
嗯，这可是最新的开发代码呀！出点错是很正常的。
到https://github.com/ultimaker/Cura上去创建了个issue，提交上去，看谁能解决这个问题。
等了两天，有其他人报同样的错误，但没有解决办法。只好自己再进一步研究。
进python控制台，一步一步运行源码。发现主要是缺少UM这个对象，这是Uranium的支持库，发现被安装到了/usr/local/lib/python3/dist-packages里面。
设置： export PYTHONPATH=/usr/local/lib/python3/dist-packages
再次运行，出现OpenGL的错误，可能是VirtualBox虚拟机的问题。后面再继续。
更新所有的库，可以用这个脚本： #!/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 ~ cd cura_dev cd protobuf git pull ./autogen.sh ./configure make -j4 sudo make install sudo ldconfig cd python python3 setup.py build sudo python3 setup.py install cd ../.. cd libArcus git pull cd build cmake .. -DPYTHON_SITE_PACKAGES_DIR=/usr/lib/python3.4/dist-packages make -j4 sudo make install cd ../../ cd CuraEngine git pull cd build cmake .. make -j4 cd ../../ cd Uranium git pull cd build cmake .. -DPYTHON_SITE_PACKAGES_DIR=/usr/lib/python3.4/dist-packages -DURANIUM_PLUGINS_DIR=/usr/lib/python3.4/dist-packages sudo make install cd ../.. cp -rv Uranium/resources/* Cura/resources/ sudo ln -s $PWD/CuraEngine/build/CuraEngine /usr/bin/CuraEngine cd Cura python3 cura_app.py
libgl出错，可能是虚拟机的问题，下次用物理机试试。
将Virtualbox的“显示－三维加速”去掉，libgl就不再报错了。
