Ok good news!
I got Qt 5.8-beta compiled (didn't tried QtWebkit yet and previous versions don't compile, dunno why)! -> I'll post a complete step-by-step here once I got everything to work.
Sent to the device just the libQt5Core and a HelloWorld app that just write a line to the console I built with QtCreator and this is the output:
/data/opt/helloconsole $ ./HelloConsole A newer kernel is required to run this binary. (__kernel_cmpxchg64 helper)
Any idea on what can be? As the image I posted here, the kernel is 3.0.56...
Thanks

@Gutemberg said in Building Qt for ARMv6l:
__kernel_cmpxchg64
Does this happen with a plain C++ hello world application without Qt?
Here something about this issue: http://uhurumkate.blogspot.de/2014/07/a-newer-kernel-is-required-to-run-this.html
It should work with kernel >= 3.1 -
@jsulm nop, other c++ apps ran just fine on the device. Only with Qt the problem happens...

Hey guys, does anyone has any idea how to workaround this issue (except by upgrading kernel since it is not possible)?
We really want to buy Qt but we are struggling with this major blocker.
Thanks!

@Gutemberg GCC < 4.7 could help. Did you check the link I provided? There are several suggestions which can help:
- Enabling arm v7 hard-float might solve your problem (it solved mine).
- Using -mfpu=vfp and -mfloat-abi=hard might solve your problem (i didn't try as armv7 was desired).

Hello!! Do you have any news on it? Did you even run sme qt application on S920? If you did, can you tell us about?
thanks!
