Re: cross-compiler intel -> powerpc-gnu-linux

[Bob Robison <brobison at swri dot org>]

OK, I got the new (2.9.5.0.46) binutils and built it with no real problems.  I configured gcc
adding a -with-headers line to point at a copy of powerpc-linux kernel
headers that I have (from a fairly recent kernel).  I was able to get successfully through the gcc
build with that.  Now I
need to build glibc.  This seems more complicated.  I tried the following configure line, and
directly referenced the sys-include directory utilized in the gcc build.  (I know this sounds
kludgy... I'm open to other ideas!)  The build continued on for quite a ways before failing.


#!/bin/sh
CC=powerpc-gnu-linux-gcc ../glibc-2.1.3/configure --host=powerpc-gnu-linux
--build=powerpc-gnu-linux --target=powerpc-gnu-linux
 --prefix=/usr/crosslinux --exec-prefix=/usr/crosslinux --program-suffix=linppc -v
--enable-languages=c --with-binutils=/usr/cr
osslinux/powerpc-gnu-linux/bin --enable-add-ons=linuxthreads,crypt
--with-headers=/usr/crosslinux/powerpc-gnu-linux/sys-include

(ignore the linewraps)  I had to but in host= and build= for powerpc to get things cranking.  It
goes for quite a while, but then while trying to do a link step it complains:

and a bunch more __syscall_xxxx undefined.  I'm guessing that I did something dumb/obvious and
somehow the appropriate sysdefs that include syscall are not being built, or included in my
temporary libc.

Can anyone shed some light on this?  I'm not real familiar with where to look for gilbc
configuration/help.  The stuff I have seen does not address the cross-environment.

thanks,
bob
