Installing Qt/Embedded

Hi,
I have some problems with installing Qt/Embedded.
I have followed the installation procedure porvided by Tolltech.
However, there is an instruction to enable the Linux frame buffer at /dev/fb0
How can I do that?
Please advice.

I'm running Red Hat Linux 8.

QT/Embedded is for hand held/pdas only, for redhat on a pc you need qt-x11-free.

Yes,
but I have also read that I can develop applications with Qt/Embedded on a desktop first and then port it over to a handheld.

Need advice to enable Linux frame buffer.

Well, the frame buffer is a kernel option.

Most distro's have it enabled by default, but we don't know what distro you use because you havn't filled out all your details.
<----over there.

Redhat should have the frame buffer already. Do you have kde installed? If you do then QT will be installed already.

Yes, I have selected "install everything" option when I was installing Red Hat Linux 8.

I have also install the Qt package according to the installation instruction. However, when I try ./start_demo I do not get any response.
The installation instruction do mention that I need to enable the frame buffer.
How do I check that?

Ok, I have selected the depth to be 32 when I was installing Qt/Embedded.

I'm using a ATI Radeon 7500 graphics card with a NEC MultiSync LCD monitor.

When I try to start Qt, nothing happens....

Hi,
Ok, I have changed to the KDE desktop settings. When I click on "start_demo" under examples/launcher, I get a "Couldn;t find program" prompt.
What should I do?

Open a console, change to the demo directory and do "./demo"
