Re: [ECOS] conflicts problem

[Yin Bao <yin dot bao at biometricsolutions dot com>]

I cannot help you directly but  ecos 1.3 is very old and you might want
to use the latest ecos from CVS. To share my experience, even with
the latest ecos I got similar conflicts when trying to build gdb stubs, 
I didn't
investigate too much since I ended up using redboot, which seems to
be recommended more. I had to rebuild it for my platform though.
