[mpich-discuss] Problem compiling gromacs-4.0.5 against mvapich2-1.4rc1

[chris.neale at utoronto.ca]

Hello,

I was having the same problem with gromacs mvapich2 until I found this  
post. I would rather not use the branch version for production  
simulations right now, so I have taken the mvapich2-1.4rc1-3378.tar.gz  
distribution and modified

src/mpid/ch3/channels/mrail/src/gen2/ibv_channel_manager.c
at line 503
from:
unsigned long debug = 0;
to:
static unsigned long debug = 0;

as per mvapich2-trunk-2009-07-23

The compilation runs to completion and I am hoping that you can offer  
a bit of advice.

1) Is this the only change that was completed in order to address  
Jerry's original probem?

2) Is this fix stable with the mvapich2-1.4rc1-3378.tar.gz distribution?

Thank you,
Chris.

We've committed a change to our source this morning that changes this
definition of debug to static so that this shouldn't cause any conflicts
in the shared namespace.  Can you try building the latest from trunk and
confirm that this resolves your problem?
