qtbase. 5.12.4 For BeagleBone Black

comarius

Hi,
I am trying to cross compile qtbase.git 5.12.4 for beaglebone
Current BBB distro is:
Linux beaglebone 4.14.108-ti-r108 #1 SMP PREEMPT Tue Jun 18 05:11:38 UTC 2019 armv7l GNU/Linux

Current QT is: QT Version: 5.7.1 installed from apt debina repos.
I am trying to cross compile the QT5.12.4
I am using the cross compiler form https://github.com/RobertCNelson/ti-linux-kernel-dev which is.

Anyone have any workaround or where to look
