HOWTO build qtcreator - 'bitbake meta-toolchain-qt5' does not create qtcreator

[PWilk.1]

Following instructions @

https://www.emsyslabs.com/how-to-compile-linux-using-yocto-for-stm32mp1/

and

https://koansoftware.com/yocto-project-meta-layer-for-stm32mp1-by-koan/

I'm led to believe that a qtcreator executable or script will be created which I can run on the host (Debian) to create and cross compile a QT5 app for STM32MP157.

I'm new to QT but need to create a simple UI to run on STM32MP157, what am I missing ?

Thanks in advance.

Hi @wpaulilkinson​ 

Do you mean that you didn't get the script and executable as described in point 17 of https://www.emsyslabs.com/how-to-compile-linux-using-yocto-for-stm32mp1/ ?

Or this results is not your expectation ?

Thanks for clarification.

Thanks Oliver,

Neither the executable stm32_qtcreator or script stm32_qtcreator.sh are created, well not on my desktop or in /opt/st/stm32mp1/2.6-snapshot.

environment-setup-cortexa7t2hf-neon-vfpv4-openstlinux_eglfs-linux-gnueabi is present in /opt/st/stm32mp1/2.6-snapshot.

My expectation is that both script and executable should be created.

Best regards,

Paul.

Hi @wpaulilkinson​ the QtCreator is an independent executable. It is an IDE provided by Qt (see their website).

If you want to build cross-compiling Qt code using QtCreator you have to setup the cross compilation environment before you call QtCreator.

To do that you have two options: 1. open a terminal, setup environment, call Qtcreator; 2. add the cross compilation environment script into a script.

I usually prefer to copy the existing script Qt/Tools/QtCreator/bin/qtcreator.sh and modify it

cp Qt/Tools/QtCreator/bin/qtcreator.sh Qt/Tools/QtCreator/bin/qtcreator-stm32.sh

and insert a line like that (you have to adapt it to your cross compiler)

#! /bin/bash
 
# Bourne shell(sh), use the . command to source a file
.   /opt/st/stm32mp1-disco/2.6-snapshot/environment-setup-cortexa7t2hf-neon-vfpv4-openstlinux_eglfs-linux-gnueabi

Thanks Marco,

Your answers make sense and tie up with the results of 'bitbake meta-toolchain-qt5 ' in my environment.

In the interim I used Qtcreator to create a simple QT5 UI and created a recipe to cross compile the code.

Best regards,

Hi Marco and Paul,

I have installed qtcreator and sourced the correct script from step 17 before calling qtcreator. But After setting up my device kit in qt I get errors as if qt is still trying to compile for my x86 64 bit Linux host. Is there a special way I have to install qtcreator?

main.o: file not recognized: file format not recognized

Thanks for the help
