Re: Running Qt applications on QNX
Hi,
There are a couple of issues here...
> We are also trying to run QT based application on QNX4.25.
I don't think anyone ever did this.
> We need to get QT compiled on our Ubuntu Linux machine for QNX4.25.
Do you even know how to develop applications for QNX 4? If you knew, you'd be aware that QNX 4.25 cannot be targeted
from Linux.

Let's go to the realm of fantasy for a moment and imagine you could build Qt (say, Qt4.8, or even Qt5) for QNX 4.25.
That would only work using the Watcom compiler shipped with QNX 4.
Even if that succeeds, there is no support inside Qt targeting QNX4. For every OS that is supposed to run Qt
applications, there is a "platform plugin", and there is none for QNX4 that I'm aware of. Someone would need to write it
- can you do it?
On the other hand, Qt support is all there for QNX 6.6. The effort migrating to QNX 6 will be indefinitely lower than
trying to get Qt running on QNX4. Face it, QNX4 is as old as Windows 3.11!
Now, there might be reasons preventing you from migrating, e.g. you have lost your source code. Then, maybe, you could
try the RTS Hypervisor. Maybe RTS can support QNX4, and this way you can continue running your QNX 4 based code on one
of the many cores of today's x86 CPUs. The other core could run QNX 6 and there you can run Qt. :) Done!
I strongly suggest contacting your QNX Sales Rep to discuss options for a CSP (Custom Support Plan) Service. Of course,
if you don't have any budget, you are doomed.
Good luck and Best Regards,
- Malte
