RE: Help w/ gcc cross build failing

["Jon Watson" <j-watson at airvananet dot com>]

I'm not sure I understand how to use newlib per your suggestion (I've never built GCC before)... The build is failing in the bootstrap target of the
actual crosscompiler build - I'm not building genmodes.o for use on the final powerpc target, I'm still trying to bootstrap GCC 3.4.1 and build the
crosscompiler itself. 

The crossgcc/GCC FAQs & web sites I've read say to 1) build the bin-utils 
(for the target), 2) the compiler (GCC), and 3) build newlib or glibc for 
my target. I'm still on step 2.

Do you mean that I need to build newlib for a cygwin PC host/target and then 
before build GCC 3.4.1 (I would have to reconfigure/rebuild everything)?

Thanks,

Jon Watson

I suspect you want newlib.
