[ECOS] Help with linux synthetic target, please.

[Gordon Scott <g dot ecos dot a at gscott dot co dot uk>]

Hi,

I've been trying to do this apparently simple task for hours and keep
falling.

I've finally gotten eCos itself to build (configtool, Build->Library)
after discovering the rather hidden hal/synth...host stuff, but I'm now
falling at getting the tests running.  configtool, Build->Tests fails
with a rather fundamental undefined reference: __write that sounds like
I still have some host support stuff missing. What's amiss, please?

Here's the tail of the Build-Tests output, if it helps.

Hmm, another question .. the two tests that do appear to have made
OK, 'basic' and 'context', will run in a ddd window, but never break
anywghere in the main() function supplied. I get the impression that
main() is a placeholder to keep linker happy and not breaking ther is
normal. Right? .. or do I have some other fundamental problem?

Thanks.

	Gordon.
