[fpc-devel] Native compilers for non-x86

[Mark Morgan Lloyd]

I'm having another of my periodic attempts at getting various systems 
up-to-date here, and I wonder if I could ask for help with build problems.

First machine is an ARM-based Linksys NSLU2 "Slug", running Debian 
"Squeeze" i.e. little-endian EABI. I've previously managed to build for 
this using (I think) 2.5.1. I experimentally reverted to 2.4.0 but an 
attempt at building gave me

/bin/mkdir -p arm/units/arm-linux
/usr/local/bin/ppcarm -Ur -Xs -O2 -n -Fuarm -Fusystems 
-Fu/usr/local/src/fpc/fpcbuild-2.4.0/fpcsrc/rtl/units/arm-linux -Fiarm 
-FE. -FUarm/units/arm-linux -dRELEASE -O- -gl -vt -darm -dGDB

Using trunk downloaded last night progresses further but eventually 
fails with

make[5]: *** [buildpasjpeg.ppu] Error 217

In both cases the commandline I'm using is

make 'NOGDB=1' 'OPT=-O- -gl -vt' 'EXTDEBUG=1' all

I've added extdebug in an attempt to enable -an for listings although so 
far I don't think it's working (when looked at on other platforms)- is 
this the right way of doing it?

Can anybody point me at a fix, or suggest a specific version I should be 
using?
