I have done a bit of research of my own...

Basically, what was done is to try compiling for emulator and then translating it to the native symbian code...

OK.

Let's think differently, if I would use Nokia Series 60 Symbian SDK, would there be a difference of what kind of code the emulator likes?

I mean PE or ARM ?

Anyway, maybe I should try compiling for THE DEVICE and then manually run it on the device...

Just to try if it works.

How should I configure makefiles to get the right cross-compiler?

P.S.
I'm have the latest svn from the svn.freepascal.org ...

Not really. What was done is for both, but focused on the emulator, because it´s faster to develop on it (well, maybe not considering the lot´s of linker problems I faced so far). There is no intention of translating a emulator executable to the device.

In fact, it´s quite easy to create device executables because the gnu binutils work for it.

I have no idea ... you need to look at the S60 docs and find out.

It´s not really PE or ARM. PE is a type of executable, ARM is a processor architecture. I don´t remember exactly the name of the executable type on the device, but it´s a special type of PE with modifications.

My experience so far is that this is easier then writing for the emulator, but it will take a lot of time to build a rtl without a emulator.

Considering that the current rtl is targeted at uiq, you should read the old topics I posted here about uiq development and do the same for s60, from the start. We also need a mechanism to select which symbian type of target we want.
