Setting Up the QT Cross-Compilation Environment on iMX6 Yocto Platform

Install Essential Library Files on Ubuntu

If installation fails, execute the following two commands in order:

apt-get upgrade

apt-get update

Then install the above library files.

2. Set Up JDK Development Environment

Download jdk1.6.0_45, then install the related JDK library files and set environment variables.

3. Install Yocto Cross-Compilation Tools and QT Development Environment as referenced:

Next, set up the cross-compilation environment

Host Environment: Ubuntu 12.04, 64-bit.

Cross-compilation Tools: Poky 1.5.3 cross-compilation toolchain and related tools.

1. Install Cross-Compilation Tools

Unzip the Poky cross-compilation tool package to the /opt directory.

1$ sudo cp fsl-imx-x11-Yocto_1.5.3.tar.bz2 /opt
2$ cd /opt
3$ sudo tar jxvf fsl-imx-x11-Yocto_1.5.3.tar.bz2

At this point, use the ls command to check.

1$ ls -1 /opt/poky/1.5.3/

4site-config-cortexa9hf-vfp-neon-poky-linux-gnueabi
5sysroots
6version-cortexa9hf-vfp-neon-poky-linux-gnueabi

Assign user or group to the cross-compilation tools, where XXX is your Ubuntu username.

1$ sudo chown -R XXX:XXX /opt/poky

2. Install QT Creator

I downloaded qt-creator-opensource-linux-x86_64-3.2.1.run, the installation process is as follows. Similarly, copy it to the /opt directory, and run it directly to enter the installation interface, as shown below:

1$ sudo cp qt-creator-opensource-linux-x86_64-3.2.1.run /opt
2$ cd /opt
3$ ./qt-creator-opensource-linux-x86_64-3.2.1.run

3. Configure the Running Environment of Qt Creator

Navigate to the /opt/qtcreator-3.2.1/bin directory and execute the command $ ./ qtcreator.sh, to run Qt Creator.

Then, in the Qt running interface, click on the menu bar “Tools –> Options –> Build&Run” to configure accordingly.

Next, configure the cross-compiler

Add a “Manual”, click Add –> GCC, and add a GCC.

The path of the cross-compiler is: /opt/poky/1.5.3/sysroots/x86_64-pokysdk-linux/usr/bin/arm-poky-linux-gnueabi/arm-poky-linux-gnueabi-g++, then click apply.

Set Kit

Add a “Manual”, click Add, click Browser, and select Sysroot as:/opt/poky/1.5.3/sysroots/cortexa9hf-vfp-neon-poky-linux-gnueabi.Click Compiler, and select the previously configured GCC.

Then click apply.

Finally, click OK to exit. Thus, the Qt development environment for the i.MX platform is set up, and you can start developing Qt applications in this environment!
