qt5 virtual keyboard error What should I do?

Hello @WSung.2​ ,

If you are using the Distribution package to generate your image, you can ask Yocto to take other recipes to install. This is the case for the Virtual Keyboard.

For example, in a local.conf, you can have this:

IMAGE_INSTALL_append = " \

qtcharts \

qtsvg \

qtvirtualkeyboard \

qtlocation \

qtquickcontrols2 \

qtquickcontrols \

"

Here you can see that for my Qt application, I need to add more Qt libs, and the Virtual Keyboard is included.

Kind regards.

Erwan.

DISTRO=openstlinux-weston MACHINE=stm32mp1 source layers/meta-st/scripts/envsetup.sh

bitbake st-example-image-qtwayland

​

What should I do now?

@WSung.2​ ,

Excuse me, the IMAGE_INSTALL_append that I put was a personal example, you do not have "boot2qt" and that is logical. Just remove it.

In fact, if virtualkey board is the only lib that miss, you can only put this one.

Moreover, if you want to make a big qt application, I advice you to use EGLFS instead of qtwayland, because of perfs. You can find information on this wiki page : https://wiki.st.com/stm32mpu/wiki/How_to_build_and_use_an_SDK_for_QT

1. It seems to work in QT virtualkey board boot2qt.(Guess I'll have to include it when compiling)
2. EGLFS throws an error
3. st Do you have a Korean/English keyboard?​(If yes, please tell me how to use it.)

@WSung.2​ ,

2) Did you try to compile the baseline (bitbake st-example-image-qt) without making any change inside?

After that, if it works, we can check what is wrong with your personal project that you try to include inside.

3) As concerns virtual keyboard, this is a library directly developed by Qt, that are integrated by STMicroelectronics. We do not develop this lib and so we do not know which language are exactly usable inside.

Rgs.
