Re: cannot open crt0.o

[Abhijit Deshpande <abhijit at softjin dot com>]

Hi Bill,

I followed exactly same configuration described at 
http://billgatliff.com/twiki/bin/view/Crossgcc/BuildBootstrapGcc to build 
the bootstrap gcc.

And then I tried to build newlib as per the configuration 
described at http://billgatliff.com/twiki/bin/view/Crossgcc/BuildNewlib.

But still, configuration for newlib fails, as it expects crt0.o to be 
already built. Does, bootstrap compiler expected to build crt0.o??

Regards,
Abhijit.
