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<code>

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

Tools/Options > build & run > tab tool chains > 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.
