Hi Ralph,
Nope that doesn't fix the problem I'm hitting. I tried to build the opmi trunk
on a system with a much older gcc compiler (4.4.7) and it compiled :)! But
I'd like to be able to compile opmi with a newer gcc like the one on my opensuse
13.1 box.
The preprocessor is pulling in the system malloc.h and that's where things blow
up:

I believe the issue is actually in opal/util/malloc.h, Howard. I noticed this
while looking around this weekend - someone included opal_config.h in the
malloc.h file even though it explicitly says "DON'T DO THIS" in that header
file.
#ifndef OPAL_MALLOC_H
#define OPAL_MALLOC_H
#include "opal_config.h"
#include <stdlib.h>
/*
* THIS FILE CANNOT INCLUDE ANY OTHER OPAL HEADER FILES!!!
*
* It is included via <opal_config_bottom.h>. Hence, it should not
* include ANY other files, nor should it include "opal_config.h".
*
*/
Don't know why someone did that, but you might see if it fixes your problem

Hi Folks,
As I said last week, I'm noticing now that on my opensuse 13.1 system and gcc
4.8.1, when I do a fresh
checkout of trunk ompi and try to build, without any configure options,
mca_base_mpool_frame.c
does not compile.
The reason is there is a conflict in opal_config_bottom.h and the contents of
malloc.h,
which for my system is pulled in by the preprocessor.
If I undefine HAVE_MALLOC_H in this file, the code compiles fine.
Alternatively,
one can also move the malloc.h include prior to the opal_config.h include and
things
work. Alternatively, one can add the OPAL_DISABLE_ENABLE_MEM_DEBUG define
as in mpool_base_lookup.c , and the compile problem similarly goes away.
I'd like to check in a fix for this. I'd prefer to just move the std include
files ahead
of the opal_config.h include. I'd like to do this today unless someone objects.
I'm somewhat surprised I'm the only one seeing this though.
Howard
