This time is the oabi compiler that fails (natively compiled on real
arm hardware).
I tried both starting with 2.2.0 and with a 2.3.1 one made with -O-:

Surely you're right, but native compiling wouldn't left me wondering if
the problems are due to the bleeding edge compiler or to some quirk in
the crossbinutils[*] or the libraries'

Hi Luca
Please give me the full command used for cross compiling with all the

Is it "-O-" or just "-O"?
It is "-O-", i.e. turn off optimizations. If you update from svn you
shouldn't need that.
As per the full command, it's somewhere in one of my pre

Hi Luca

I am able to run the ppcarm which was generated by cross compiling, on the

Hi Henry, Luca
I got a 'ppcarm' after compiling the fpc-svn. I copied the pparm to the
qemu-system-arm emulated machine and tried to compile a Helloworld.pas.
fpc showed some errors related to FPU and stopped. Then i copied many *.o

won't the startup code need to change for eabi? i can at least see a
problem with the exit syscall there that won't work with eabi.

Thanks to Henry Vermaak I rebuilt the cross compiler with -O- and now it
prints "hello" :-)
I'm trying to cross-compile the gtk2 example but it seems the compiler
is ignoring -X
I've fixed some stuff, so it should work with -O2 as well.

for info:
the problem here is that the arm eabi compiler (and/or rtl) must be
built with -O- to work.
