Hi,
I installed Qnx6.6 + Qt5.3.0 on my Rhodeus x86 SBC and I tried to execute my Qt demo program QtHelloWorld but says:

QT_MESSAGE_PATTERN: Unknown placeholder %{if
Process 126996 (QtHelloWorld) terminated SIGABRT code=0 by process 126996 value=0.
Abort (core dumped)

I tried also to do the same thing on my vmware machine (with Qnx6.6 + Qt5.3.0) and it works fine.

Can be a graphic driver problem?

I used Screen in both platforms but on vmware I used  the "/usr/lib/graphics/vmware" configuration dir while on x86 I 
used "/usr/lib/graphics/vesabios".

x86 ENV VARS:

  begin class framebuffer

Can somebody help me?
