i.MX6 configure option -no-xcb

aheimberger

Hey guys, I try to build a qt application for an i.MX6. I have cross compiled the application for a specific yocto target, but now I ran into the problem, that the application can be started manually, but not using systemd for startup, because it is missing library xcb.

I found those two articles, which mention using the configure option -no-xcb:

But I do not understand how to use ./configure, can't find it within the directory where Qt is installed.

Thanks for your help.

The no-xcb option and the ./configure script is only needed if you want to build the qt libraries by your own.
configure is used to create the makefiles and prepare the build, the no-xcb option tells the script that the qt libraries should be compiled without x-server support.

You could try to add the path to the xcb library to the enviroment variable LD_LIBRARY_PATH.

TY : I set environment variable QT_QPA_PLATFROM='eglfs'. This must be done before the application starts. This environment variable is not available during boot.

It can also be done by starting the application directly with:
./appName -platform eglfs

@aheimberger you should add that in profile
