[fpc-pascal] fpc arm big endian help

2006-10-23 Thread Terry Kemp 
Hi all

I'm working on some code for the NSLU2 'slug'.
How do I get ppcarm to compile in big endian mode?
I have done it once before but I've lost the magic wand somewhere.

Do I need to build from source as in a post I saw on devel list...
change system_arm_linux_info.endian to endian_big in 
/pp/compiler/systems/i_linux.pas
then run make clean CPU_TARGET=arm CROSSINSTALL=1
then make crossall CPU_TARGET=arm OS_TARGET=linux

heres one I prepared earlier...
$ file /opt/slugtest
/opt/slugtest: ELF 32-bit MSB executable, ARM, version 1 (ARM), for
GNU/Linux 2.0.0, statically linked, for GNU/Linux 2.0.0, stripped

so I know it worked before - but now...

Re: [fpc-pascal] fpc arm big endian help

2006-10-23 Thread Matt Emson 
Ooops.. this time with a reply.. prt0.o is a bit of assembler IIRC... is 
it compiled for bigendian? That looks to be your issue. Part of the RTL is 
in little endian format and needs to be recompiled.
