Note: This guide is intended for our stock Yocto image using systemd. On custom images, the same instructions should apply if a cross toolchain is built. This can be built through Yocto with bitbake meta-toolchain-qt5. Be sure to update the paths if using a different distribution.


Install the qtcreator tool on a host Linux PC. Any recent version from a modern Linux distribution should be sufficient and work without issue. On a Debian/Ubuntu desktop, run: 

sudo apt-get update && sudo apt-get install qtcreator -y

The SDK which includes the Qt support will also need to be downloaded. The cross toolchain is only available for 64-bit Linux host PCs:

In order to install the toolchain, use the following commands to run the installation script: 

chmod a+x poky-*.sh
sudo ./poky-*.sh

These instructions assume the installation path will be the default at /opt/poky/3.0.2/


Note: An environment script has to be sourced before every execution of qtcreator. Without this, builds will fail. 
source /opt/poky/3.0.2/environment-setup-cortexa9t2hf-neon-poky-linux-gnueabi
qtcreator


Qt Creator needs to be configured to build using this toolchain. Once Qt Creator is launched, select Tools->Options->Devices Click Add, select Generic Linux Device, and then click Start Wizard

Qt Device Configuration

On the next page specify the IP address or hostname of the device running Yocto. In this example, the unit has an IP address of 192.168.2.45 obtained via DHCP. The default Yocto image will use the user root with no password to connect. Set the name to TSIMX6

Qt Device Configuration

It will then verify connectivity. Click close and continue.

Qt Device Test
Note: The paths given in the images below may not match the latest toolchain, but are meant to show where these values would go. Follow the text appropriate to the architecture of your host PC for the correct values


In the left column of the Options menu, select Build & Run. On the Qt Versions tab, click Add in the upper right to configure the TS Kit. Qt Creator may see the qmake binary added to your path from the sourced environment script. If this is detected, add in the string TSIMX6 to the title as shown in the photo below. If it is not autodetected, add the full path and ensure the version name is set to TSIMX6 Qt 5.13.2. This will allow it to be recognized when setting the right binary for the kit. 

/opt/poky/3.0.2/sysroots/x86_64-pokysdk-linux/usr/bin/qmake
Qt Versions tab


On the Compilers tab click Add, select GCC then C. Set the Name to TSIMX6 GCC. For the Compiler Path use the following: 

/opt/poky/3.0.2/sysroots/x86_64-pokysdk-linux/usr/bin/arm-poky-linux-gnueabi/arm-poky-linux-gnueabi-gcc

Repeat the above steps for the g++ compiler; click Add, select GCC then C++. Set the name to TSIMX6 G++. And for the Compiler Path use the following: 

/opt/poky/3.0.2/sysroots/x86_64-pokysdk-linux/usr/bin/arm-poky-linux-gnueabi/arm-poky-linux-gnueabi-g++
Qt Compiler tab

On the Debuggers tab click Add. For name, specify TSIMX6 GDB. For the path, specify the location of gdb with the following: 

/opt/poky/3.0.2/sysroots/x86_64-pokysdk-linux/usr/bin/arm-poky-linux-gnueabi/arm-poky-linux-gnueabi-gdb
Qt Debugger tab

On the Kits tab click Add. For Name, enter TSIMX6. Set device type to Generic Linux Device. Set the device to TSIMX6 (default for Generic Linux). Set Qt mkspec to the following (make sure there is no space at the end): 

/opt/poky/3.0.2/sysroots/cortexa9t2hf-neon-poky-linux-gnueabi/usr/lib/mkspecs/linux-oe-g++


Set C Compiler to TSIMX6 GCC and C++ Compiler to TSIMX6 G++. Set Debugger to TSIMX6 GDB. Set the Qt version to TSIMX6 QT 5.13.2. Finally, click Apply.

Qt Kit tab
Note: If there is a red exclamation point over the kits icon, it indicates that the compiler ABI does not match. In this case, you will need to revisit the "Compiler", "Debugger", and "Qt Versions" tabs, and browse the host PC for these files manually rather than copy/pasting the paths from these instructions. This is a bug in Ubuntu 16.04's Qt Creator, and may be in later versions as well.

At this point Qt Creator is set up to begin a hello world project.
