Thank you Alfred - a little further now.

I have pasted the full output from lazbuild for reference.
It seems the linker is trying to use 'crtbeginS.o' for my base system 
(x86_64)
I guess I need to tell it to redirect to 'crtbegin' in 
'/mnt/Shared/Apps/fpcupDeluxe/cross/lib/arm-linux', but I dont know how 
(as yet)

Still working at it though :)

/mnt/Shared/Apps/fpcupDeluxe/lazarus/lazbuild --os=Linux --cpu=arm 
project1.lpi
using config file /mnt/Shared/Apps/fpcupDeluxe/lazarus/lazarus.cfg
