apt-get install Qt4 on the Rasperry Pi

Tutorial : apt-get install Qt4 on the Rasperry Pi

Using the Raspbian image

apt-get

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

• sudo apt-get install qt4-dev-tools
  
  

Then I went for Qt Creator

• sudo apt-get install Qtcreator
  
  

I also installed

• sudo apt-get install gcc
  
• sudo apt-get install xterm
  
• sudo apt-get install git-core
  
• sudo apt-get install subversion
  
  

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

Qt Creator安装后，一打开就提示plugin错误，并且没有这个“Options > build & run > tab tool chain > button add”菜单。
