[Lazarus] on ARM Linux ,SoftFloat and EABI issues

[Nataraj S Narayan]

Hi

I get the following strace out put when executing a fpc cross compiled
binary using ppcrossarm (generated from latest fpc svn using following
script :-

#!/bin/bash

ALLOPTS="CPU_TARGET=arm OS_TARGET=linux BINUTILSPREFIX=arm-linux-
CROSSBINDIR=/home/nataraj/arm
-2008q1/bin FPC=/usr/local/bin/ppc386
INSTALL_PREFIX=/usr"

make clean crossall $ALLOPTS OPT="-dFPC_ARMEL" && \
sudo make -k crossinstall $ALLOPTS OPT="-dFPC_ARMEL"

My ARM Linux kernel is on Atmel AT91SAM9263 is
Linux at91sam9263ek 2.6.25 #34 Sat Jun 7 20:02:51 IST 2008 armv5tejl unknown

I use  bin utils from CodeSourcery for cross compiling EABI kernel as
well as fpc.
The kernel is compiled with

CONFIG_AEBI=y
CONFIG_ARM_THUMB=y

But I am not able to enable OABI_COMPAT=y.

Why dont my binary work on the Arm board? What else is to be done?

regards


Nataraj
