Many thanks for your reply, Vincent. Unfortunately I have no experience
in building gcc cross-compilers (including cegcc), so I need to ask
another question.
Is it really as easy as substituting "sh4" for "arm" in the places
implied by your diff?
Or will it be a much bigger job than that (as that doesn't seem like 3-4
days effort!).
And when you say 3-4 days, is that 3-4 days for a gcc guru, or 3-4 days
for someone who needs to find out a lot more about how these toolchains
work (like me!) ?
And a final question: what do you think the likelihood of final success is?
Is this something that can definitely be made to work, or is it
something where there will be some final unsurmountable "gotchas" which
mean that it could never be made to work (at least without a huge effort
- e.g. like the problems on list reported for Windows Mobile 6.1 DLLs).
Thanks again,
Hywel.
