树莓派中安装QT

环境：

主机:WIN7

硬件:树莓派

 

步骤:

参考链接:http://qt-project.org/wiki/apt-get_Qt4_on_the_Raspberry_Pi

 

Firstly I got the development tools needed by Qt Creator in the hope it would be less heavy for the Pi to download separately.

1. sudo apt-get install qt4-dev-tools

 

Then I went for Qt Creator

1. sudo apt-get install Qtcreator

 

I also installed

1. sudo apt-get install gcc
2. sudo apt-get install xterm
3. sudo apt-get install git-core
4. sudo apt-get install subversion

this gives as a result Qt Creator 2.5 with Qt 4.8.1 32 bit

 

如果出现问题:e: unable to locate package qt creator,则输入以下命令更新

sudo apt-get update && sudo apt-get upgrade

 

如果还是有问题,尝试sudo apt-get install qtcreator

成功后可以运行qtcreator:

此时还需要添加编译链:

Problem : no toolchain.

We can only compile for remote embedded devices and this is not the case here, because we are on the Pi and not remotely accessing it.

I added a gcc toolchain

Options > build & run > tab tool chain > button add
Choose GCC

• Then set compiler path : /usr/bin/arm-linux-gnueabihf-gcc-4.6
• Debugger : /usr/bin/gdb
• Mkspec : default

 

Qt Creator seems to detect that we are going to deploy on a remote target.

To fix this :

• Go to menu help > about plugins
• Uncheck device support > remote linux
• Restart Qt Creator
• Go to tools > options TAB > build & run > Qt versions > add “/usr/bin/qmake-qt4”

 

It will then show up as a desktop project in the project wizard instead of embedded.

配置好之后,尝试运行一个简单的程序,效果如下:

运行成功!不过编译很缓慢,正式开发估计还是得在PC上开发好之后再进行移植.
