最近要搞一个嵌入式项目，在I.MX6平台上基于linux系统使用QT做界面开发，于是就研究了一下如何对QT 5.9.2版本的代码进行下载和编译。同时，因为嵌入式平台上涉及到是否启动OpenGL，还得分成两个版本来编译。再加上PC端，总共就有3个版本了，如下：
- x11桌面OpenGL版，将其命名为qt-5.9.2-x11-opengl版本，用于在PC端模拟调试带OpenGL的程序。
- arm嵌入式常规版，将其命名为qt-5.9.2-arm-normal版本，用于在I.MX6平台上运行不带OpenGL的程序。
- arm嵌入式OpenGL版，将其命名为qt-5.9.2-arm-opengl版本，用于在I.MX6平台上运行带OpenGL的程序。
下面就开始详细介绍搭建、安装、编译等全过程的记录。
一、准备工作
1、开发环境介绍
- 主机系统：win10（64位）；
- 虚拟工具：Virtualbox 5.2.0；
- 虚拟系统：Ubuntu 14.04（64位）；
2、下载QT源码
直接去官网（http://download.qt.io/archive/qt/）下载QT的源码即可。
由于某些历史原因，我这里下载的是5.9.2版本。建议大家也同样使用这个版本，毕竟我自己已经亲自验证过了。如果您使用新的版本，可能会遇到一些其他的问题。
这里需要注意的是，我们要下载的是源码压缩包，而不是现成编译好的可执行文件。所以，请进入“single”目录进行下载。我选择的是后缀名为tar.xz的文件（因为它比较小），解压得分两步走，先解开xz，然后再解开tar，命令如下：
xz -d qt-everywhere-src-5.9.2.tar.xz
tar -xvf qt-everywhere-src-5.9.2.tar3、安装编译工具
请确保系统中已安装gcc、g++和OpenGL。可使用以下命令进行测试并验证它们的具体版本：
I、gcc工具
gcc --version如果没有响应，或者提示gcc没有安装，则可以使用下述命令进行安装：
sudo apt-get install build-essential安装完成之后，同样使用上述命令查看一下gcc的版本进行确认。
II、g++工具
g++ --version如果没有响应，或者提示g++没有安装，则可以使用下述命令进行安装：
sudo apt-get install g++安装完成之后，同样使用上述命令查看一下g++的版本进行确认。
III、OpenGL
glxinfo | grep OpenGL如果提示“程序“glxinfo”尚未安装”，则可以使用下述命令进行安装：
sudo apt-get install mesa-utils如果提示OpenGL找不到或者没有安装的话，则可使用下述命令安装（具体的详细过程可参见我的另外一篇博客：如何在Ubuntu 14.04下安装OpenGL开发环境）。
sudo apt-get update
sudo apt-get install build-essential
sudo apt-get install libgl1-mesa-dev
sudo apt-get install libglu1-mesa-dev
sudo apt-get install libegl1-mesa-dev
sudo apt-get install freeglut3-dev安装完成之后，同样使用上述命令查看一下OpenGL的版本进行确认。
4、搭建目录环境
根据QT官方的说法，建议大家不要在QT源码的目录下直接进行编译，这样会污染源码所在的目录，无法达到多个版本共存编译的效果。可以在QT源码所在的同级目录下，新建一个临时用的编译目录，只为存放编译脚本和编译所产生的临时文件。如下：
leon@Ubuntu:~/tempuse$ ll
总用量 20
drwxrwxr-x 4 leon leon 4096 8月 10 11:10 ./
drwxr-xr-x 30 leon leon 4096 8月 10 11:07 ../
drwxrwxr-x 43 leon leon 4096 10月 4 2017 qt-everywhere-opensource-src-5.9.2/
leon@Ubuntu:~/tempuse$ mkdir qt-5.9.2-x11-opengl qt-5.9.2-arm-normal qt-5.9.2-arm-opengl
leon@Ubuntu:~/tempuse$ ll
总用量 32
drwxrwxr-x 7 leon leon 4096 8月 10 11:13 ./
drwxr-xr-x 30 leon leon 4096 8月 10 11:07 ../
drwxrwxr-x 2 leon leon 4096 8月 10 11:13 qt-5.9.2-arm-normal/
drwxrwxr-x 2 leon leon 4096 8月 10 11:13 qt-5.9.2-arm-opengl/
drwxrwxr-x 2 leon leon 4096 8月 10 11:13 qt-5.9.2-x11-opengl/
drwxrwxr-x 43 leon leon 4096 10月 4 2017 qt-everywhere-opensource-src-5.9.2/于是，可以分别在qt-5.9.2-x11-opengl qt-5.9.2-arm-normal qt-5.9.2-arm-opengl这3个目录下进行不同版本的代码编译，而不会影响到源码所在的目录。
5、目标文件系统
由于最终编译出来的程序是要运行在I.MX6的嵌入式系统中，因此在编译的过程中要引入目标文件系统。我这里将该文件系统（fsl-image-gui-imx6qsabresd）解压放在/opt目录下。请记住这个目录，后面会用的到。
leon@Ubuntu:~$ cd /opt
leon@Ubuntu:/opt$ ll
总用量 32
drwxr-xr-x 8 root root 4096 8月 10 13:39 ./
drwxr-xr-x 23 root root 4096 10月 11 2017 ../
drwxr-xr-x 4 leon leon 4096 10月 11 2017 FriendlyARM/
drwxr-xr-x 19 leon leon 4096 11月 14 2017 fsl-image-gui-imx6qsabresd/
drwxr-xr-x 9 root root 4096 10月 11 2017 VBoxGuestAdditions-5.0.20/
drwxr-xr-x 6 root root 4096 6月 9 2017 wps-office_10.1.0.5707~a21_x86_64/二、x11桌面OpenGL版
1、创建配置脚本
进入qt-arm目录，新建config.sh文件，输入：
#!/bin/sh
./../qt-everywhere-opensource-src-5.9.2/configure \
-verbose \
-opensource \
-release \
-shared \
-confirm-license \
-make libs \

-no-use-gold-linker \

-prefix /opt/qt-5.9.2-x11-opengl这里“-prefix /opt/qt-5.9.2-x11-opengl“是用于指定编译之后库文件所安装的位置，你可以按照你自己的规划和要求来更改，但是其他的指令不建议更改。
为config.sh文件增加可运行属性，并运行之。大约1-2分钟之后，结束，提示配置成功：

Qt is now configured for building. Just run 'make'.
Once everything is built, you must run 'make install'.
Qt will be installed into '/opt/qt-5.9.2-x11-opengl'.
Prior to reconfiguration, make sure you remove any leftovers from the previous build.2、编译和安装
输入下述命令开始编译。由于源码内容较多，编译时间会很长，以我的电脑i3-4160 3.6GHz处理器+4G内存的配置，编译了差不多40分钟。
make -j4编译完成后，输入下述命令便可直接安装到之前预设的目录下：
sudo make install三、arm嵌入式常规版

WARNING: Cross compiling without sysroot. Disabling pkg-config
Qt is now configured for building. Just run 'make'.
Once everything is built, you must run 'make install'.
Qt will be installed into '/opt/qt-5.9.2-arm-opengl'.
Prior to reconfiguration, make sure you remove any leftovers from the previous build.
3、编译和安装
输入下述命令开始编译。由于源码内容较多，编译时间会很长，以我的电脑i3-4160 3.6GHz处理器+4G内存的配置，编译了差不多80分钟。
make -j4编译完成后，输入下述命令便可直接安装到之前预设的目录下：
sudo make install至此，3个版本的QT库全部编译和安装完成，分别位于opt目录下的指定位置。接下去就是安装QTCreator，然后在其中配置好相关的套件环境即可，在此不做记录，待下文分解。
