Err, that should be -dFPC_ARMEL of course<br>

Fpc should be compiled with -dFPC-ARMEL in OPT, not CROSSOPT<br>

I tried a very elementary code on arm-linux-uclibc, compiled
using "ppcrossarm -TLinux -darm ttt3.pas -CfSOFT -XParm-linux-
-XR/cdrom"<br>
<br>
program kuraj;<br>
begin<br>
writeln('Hooua');<br>
end.<br>
<br>
<br>
The asm listing using -al is here: - <a moz-do-not-send="true"
href="http://pastebin.com/CG9i0x3z">http://pastebin.com/CG9i0x3z</a><br>
<br>
It dont work in the normal EABI kernel but works on OABI compat
one.<br>
<br>
I got ppcrossarm using :- <br>
gmake distclean crosszipinstall CPU_TARGET=arm OS_TARGET=linux
CROSSOPT='-CfSOFT -darm -dFPC-ARMEL -gl'
FPC=/usr/local/lib/fpc/2.5.1/ppc386<br>
<br>
<br>
warm regards<br>

Compile the code with -al, compile equivalent Pascal
code with -al and look<br>
at the differences in the generated ".s" files.<br>

<div class="im"> I changed the kernel to old 2.6.30 and
the code works on the Arm target!<br>

That kernel has been compiled with
CONFIG_OABI_COMPAT=y. Newer kernels dont<br>
show this option, only EABI.<br>

Also my ppcrossarm is :-<br>

What do you make of it?<br>

<br>
That you did not reply to the suggestions I made in my
previous message. Please say what you did and what happened,
even if it didn't work. It's not nice to spend time on
trying to help someone, if that person then simply ignores
what you write and replies with something completely
different.<br>
<br>
The EABI requires that the stack is always aligned to 8
bytes on entry/exit of subroutines, and you probably mess up
the alignment with the manually inserted return instruction.<br>
<br>
Also, make sure that you compiled an EABI cross-compiler
(ensure that -dFPC_ARMEL is part of the OPT setting of the
"make" invocation used to compile FPC).
