Installing QT in Raspberry Pi

Installing QT in Raspberry Pi

Environment:

Host: WIN7

Hardware: Raspberry Pi

Steps:

Reference Link: 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 is less heavy for the Pi to download Separat Ely.

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 + bit

If the problem occurs: e:unable to locate the package Qt Creator, enter the following command to update

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

If there is still a problem, try sudo apt-get install qtcreator

After success, you can run Qtcreator: You also need to add a compilation chain: Problem:no toolchain.

We can only be compile for remote embedded devices and this is not the case here, because we be on the Pi and not remotely a Ccessing 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, we is 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'll then show up as a desktop project in the Project Wizard instead of embedded.

Once configured, try running a simple program with the following results: Run successfully! However, the compilation is slow, and the formal development estimate will have to be developed on the PC before porting.
