Is what I am doing reasonable, or should I- as an example- be using 2.4.0 to
rebuild itself with -CaEABI before trying to go any further?
It's best to compile 2.4.0 with -dFPC_ARMEL (no need to use -CaEABI) and use
the resulting compiler.
Thanks Jonas. It's worth noting that the hardware is an NLSU2 "Slug", so
uname -a reports
Linux ... 2.6.26-2-ixp4xx #1 Mon Jun 21 20:07:59 UTC 2010 armv5tel GNU/Linux
I've got some meatier development boards but they came with CE and I've
not found how to get Linux onto them yet.
If I use 2.2.2 to build an initial 2.4.0 like
make 'NOGDB=1' 'OPT=-CfSOFT' all
make 'OPT=-CfSOFT' install
I get something that can compile an app provided that I still give it
-Cf. If I then try to use that to recompile itself with
make 'NOGDB=1' 'OPT=-dFPC_ARMEL' all
I get
/usr/local/bin/ppcarm -Ur -Ur -Xs -O2 -n -Fi../inc -Fi../arm -Fi../unix
-Fiarm -FE.

What should I be doing here- using both -Cf and -d?
