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

[Dick.Detweiler]

I'm going to be lazy here...

Our cross-compile environment has io.h in asm/io.h.  However, something must be 
defining HAVE_SYS_IO_H because that's what ipmi-kcs-driver.c ends up trying to 
include.  Where are HAVE_[SYS/ASM]_IO_H determined and is there something I can 
do for a quick and dirty fix?

Thanks again,
Dick

Hey Dick,

Personally, I've never seen this before.  I don't use bitbake so I don't
know much about it.  But from the output, I'd guess that your bitmake
build environment is missing some headers.  I think what it's saying is
if you have:

/usr/include/example.h

#include <foo.h>

mycode.c:

#include <example.h>

autoconf is only checking for example.h, but because foo.h doesn't
exist, it can't compile.  Just a guess, hope it helps.
