[Interest] Qt5 Cross Compiling for ARM

[Dietrich.Gossen at continental-corporation.com]

Hi,

I found the missing lib.
It's ld-linux.so.3 (actually it's a soft link that points to ld-2.11.1.so)
Its ' location is in /pathtorootfs/lib/

How do I include this in the mkspecs?

Thanks again.

Regards,

This is just a bad OpenGL ES library from your chip vendor. The library 
isn't 
self-sufficient. If you try to run the following command, for example:

                 ldd -d -r $GLLIBPATH/libGLESv2.so

It should not report any undefined references. You'll see that your 
library has 
a lot of them. Please report them to your board vendor so they can fix 
them in 
a future release. You can tell them "please link your libraries with 
-Wl,--noundefined".

In the meantime, add the necessary libraries that need to be linked 
against to 
the QMAKE_LIBS_OPENGL_ES2 variable.
