@mcggoal Good! at least a step forward.
Cross compilation is an advanced topic and needs quite some experience.
Maybe someone else can help you better than me, but at least I've some questions for you:Do you have another (native) Qt version on your system? If yes, where is it installed? Do you call an environment-setup script to set-up your cross-compiler? Usually such scripts set the environment variables needed to find the compiler, the tools and also set up the sysroot for your embedded device. Have you already verified that the files below /usr/local/lib are the cross-compiled ones? You can check with file libXXXX.so. That gives me the impression that the files are wrongly installed. Reason: /lib, /usr/lib, and /usr/local/lib are for native libraries, same applies for /bin, /usr/bin and /usr/local/bin for the binaries. Cross compiled binaries and should rather be installed in /opt or in your home directory.
