RE: [Freeipmi-devel] configure: warning while processing for powerpc / Open embedded target

[Dick.Detweiler]

Ah - I see what needs to be done.  I need to point configure to our cross 
compile tools and not the native system.  Not a straightforward thing to do in 
open embedded's bitbake-based build environment.  It automates the whole thing 
from grabbing the tarball from the ftp site to compiling and then staging the 
resulting output to the correct target rootfs tree.  I'll have to override the 
defaults being passed to configure.

Thanks for your help,
Dick

Hey Dick,

Autoconf would define sys/io.h if it found it.  So it must have found
sys/io.h and asm/io.h?
