Compilation problem.

[Lars Bj|rnfot]

Hi,

I posted an answer for this some months ago, patch added below. 
Hope it works though the versions is slightly newer. 

Regards,
Lars

The reason seems to be mpid.h that exists in two versions, 
and the mpid/via/mpid.h  seems outdated. I send a patch that 
works for me (mpich-1.2.1 and mvich-1.0a6.1). It's rough, just 
to get it to compile.

make mpilib
# fails 
# queue.c:296: warning: implicit declaration of function `MPID_AINT_CMP'
# see  diff ./mpid/ch2/mpid.h ./mpid/via/mpid.h

patch -p1 < patch-mpid.h
# make mpilib succeeds w/o errors. 

Regards,
Lars

Emulex (cLAN 1000) connected cluster running RH 6.2/2.2.19.  I've pretty much followed
the mvich installation instructions. The problem is the function MPID_AINT_CMP. It
doesn't appear to be defined anywhere not used by any code other than queue.c. Can
someone suggest a solution to this?
