Thanks for the explanation. I now understand that GCCSDK 4.1 just
produces ELF format binaries and libraries.
I've also seen the work Peter has done to convert the final ELF
executables to an absolute binary in the autobuilder to produce
these for now.

I would rather stick to the currently shipped version as well. I was just
checking if there was something in v1.11 that meant programs compiled
with GCCSDK4.1 needed it to run.

I can see why it would be easier to make them all available via riscos.info,
so if that is what you would prefer I'm happy to go along with it.
The build-website script is a wrapper around programs that can work
with any directory so it should be relatively straight forward to modify
it to build other package directories.
What other package list are we going to add?
Currently we have autobuilt which is intended for direct output from
I'm not sure what others we want - unstable, testing, stable? Any
Also how do we know when to copy something from one list to another?
I think this thread has lead to the conclusion that I should be moving
over to the GCCSDK4.1 soon to create the packaging site.
Before I do that it may be worth making a copy of the existing site
to another package list. If so which one unstable, testing ...?
I assume the AOF versions of the libraries will all need to be replaced
with ELF versions. Is there any benefit in keeping the AOF versions
