Compile error: glibc 2.3.6 with a powerpc cross compiler on Solaris Sparc.

["Dan Gora" <dan dot gora at gmail dot com>]

Hi all,

I'm trying to build a PPC 603 cross compiler (gcc-4.1.1/glibc 2.3.6)
hosted on Solaris sparc
using crosstool v.43.  I've managed to massage crosstool enough to get
the first powerpc-603-linux-gnu-gcc cross compiler built, but it's
gacking when trying to build glibc here:

I googled around a bit and found one other person who ran into the same problem:
http://www.garayed.com/linux/137835-trouble-compiling-glibc-2-3-4-a.html
but he never got a response nor posted what the solution was (if there was one).


Does anyone have an idea what may be going wrong here?  I sniffed
around a bit and could see what it was complaining about, but as far
as how to fix it... I don't know.  Any ideas would be most welcome.
I tried posting this to the libc-ports mailing list too, but am not
getting any replies there...


thanks-
dan
