吐槽下在QT官网的文档查询入口我开始一直点Docment，找来找去还是那几个没什么用的，后来点了下WIKI才发现点东西：https://wiki.qt.io/Main，可这里都是旧版的，新版还是要跳转回去。真无言，也就找到了特定设备的粟子，针对device的configure例子，还好最终还是找到了一个比较详细有内容的配置说明，点我查看原文嫌麻烦的可看我文尾的简介。
在qt-everywhere-opensource-src-5.6.0下自建个可执行脚本autoconfig.sh内容如下， 可以自行按需修改
anzyelay@ubuntu:qt-everywhere-opensource-src-5.6.0$ cat autoconfig.sh
#!/bin/sh

NOTE: Qt is using double for qreal on this system. This is binary incompatible against Qt 5.1.
Configure with'-qreal float'to create a build that is binary compatible with5.1.
NOTE: -optimized-tools is not useful in-release mode.
Info: creating super cache file /home/anzyelay/Desktop/arm/qt-everywhere-opensource-src-5.6.0/.qmake.super
Qt is now configured for building. Just run 'make'.
Once everything is built, you must run 'make install'.
Qt will be installed into /usr/local/Qt5.6-arm
Prior to reconfiguration, make sure you remove any leftovers from
the previous build.
4. 编译安装
make & sudo make install开始时由于没有加最后-skip一项.make时会遇到错误，就是关于3D插件部分编译失败，按网上的说法可以修改qt.pro，但5.6.0版的却不一样了，没有addmodule这样的语句，而是用for语句来加载“.gitmodules”这个文件里申明的模块，猜测应该可以直接在这个文件里把qtcanvas3d， qt3d , qtconnectivity, qtwayland 这几个模块注释掉，我没有这样做了，一开始是.configure后在生成的Makefile里直接修改SUBTARGETS的值，去掉“module-qt3d”之类的，如下图列举了一部分，你可以直接 寻到到上面说的几个不能编译的模块删了就行：30SUBTARGETS =
31module-qtbase32module-qtmacextras33module-qtx11extras34module-qtimageformats
我是这样编译成功的，后来看了下文档有更容易的方法，直接在配置时使用 -skip选项就行，具体说明见文尾说明。
5.拷贝库和插件到根文件系
安装后就在你prefix指定的目录下有了我需要拷贝的文件了。这里只需要拷贝一些动态库和插件目录，对，不要忘了在lib下还有个fonts文件夹也需要。
