QT5安装（null）

• QT5 uboot安装

参考：http://askubuntu.com/questions/279421/how-can-i-install-qt-5-x-on-12-04-lts

sudo apt-get install qtcreator

You can usually do this with the following commands:

sudo apt-add-repository ppa:ubuntu-sdk-team/ppa
sudo apt-get update

The next step is to install the necessary packages for Qt5 / QML 2.0 development. You can do that by running these command:

sudo apt-get install qtdeclarative5-dev

This will install the headers / libraries necessary for development with desktop Qt and QML. You will also probably want to grab the latest release of Qt Creator from this page.

I've found that Qt Creator sometimes has problems finding your new Qt5 installation. If that is the case, perform these steps:

1. open it up and go to Tools->Options
2. click the "Build & Run" section in the left menu
3. click the "Qt Versions" tab

4. click "Add..." and enter the location that corresponds with your OS:

   32-bit: /usr/lib/i686-linux-gnu/qt5/bin/qmake
   64-bit: /usr/lib/x86_64-linux-gnu/qt5/bin/qmake

• 安装包方式安装QT5.0

1、下载源：http://mirrors.hust.edu.cn/qtproject/archive/qt/5.1/5.1.0/qt-linux-opensource-5.1.0-x86-offline.run

2、开始安装：

null@dev:~/echo$ ./qt-linux-opensource-5.1.0-x86_64-offline.run

如果遇到权限问题请按如下操作：

null@dev:~/echo$ chmod +x ./qt-linux-opensource-5.1.0-x86_64-offline.run

null@dev:~/echo$ sudo ./qt-linux-opensource-5.1.0-x86_64-offline.run

3、选择安装路径为 /home/null/qt/qt5.1.0

4、在本地资源搜索并打开QTcreater

5、更改QTGCC

• Gcc路径

a、查看编译器路径：

null@dev:~$ echo $PATH
/home/null/fsl-release-bsp/build-x11/tmp/sysroots/x86_64-linux/usr/bin/arm-poky-linux-gnueabi:/home/null/bin:/home/null/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games

b、在qtcreater设置编译器路径：

/home/null/fsl-release-bsp/build-x11/tmp/sysroots/x86_64-linux/usr/bin/arm-poky-linux-gnueabi/arm-poky-linux-gnueabi-gcc

6、源文件目录：

file:///home/null/fsl-release-bsp/build-x11/tmp/work/cortexa9hf-vfp-neon-poky-linux-gnueabi/quitbattery/1.0.0-r0/QUItBattery_1.0.0

• 交叉编译环境出现错误：
