    Hi everybody,
    I need to compile Qt libs v.5.7.1 for Tinkerboard.
    Host machine: Ubuntu 18.04
    Tinker:

    root@tinkerboard:/home/amtk/MyKeyboard/bin# uname -a
Linux tinkerboard 4.4.71+ #1 SMP Thu Feb 22 18:23:31 CST 2018 armv7l GNU/Linux
root@tinkerboard:/home/amtk/MyKeyboard/bin#
root@tinkerboard:/home/amtk/MyKeyboard/bin# lsb_release -a
No LSB modules are available.
Distributor ID: Debian
Description:    Debian GNU/Linux 9.3 (stretch)
Release:        9.3
Codename:       stretch

    I'm following this post https://www.qt.io/blog/2017/05/03/qt-git-tinkerboard-wayland and I downloaded the cross-compiler and rsync-ed some folder from the device.

    When I run the configure script I see that qmake tool is compiled correctly but, when the script starts to check for various modules, it does not find some header files (that are present under sysroot/.. for example mysql.h, sql.h, ..) but, first of all, it stops checking for libGLES libraries.
    In particular the output is:

    checking for OpenGL ES 2.0...

    I checked the files under the sysroot folder looking for the opengl libraries and especially for librt (the first problem in the list):

    How can i solve, please?
    Regards!
