Charm++ parallel programming system

[Shan-ho Tsai <tsai AT hal.physast.uga.edu>]

Dear CHARM developers,

I am trying to build CHARM 6.1.3, which is included in
the NAMD 2.7b2 source tarball, on a Linux RHEL4.8 machine
with IB. I compiled it successfully using MVAPICH2 1.2
(built with gcc/g++ 3.4.6). However, now I am trying to
build it using MVAPICH2 1.4 (also built with gcc/g++ 3.4.6)
and I am getting an error in the compilation of
src/conv-core/isomalloc.c

The error is

../bin/charmc  -O3 -nobs -c -I. isomalloc.c
isomalloc.c: In function `call_mmap':
isomalloc.c:1526: error: `MAP_ANON' undeclared (first use in this 
function)
isomalloc.c:1526: error: (Each undeclared identifier is reported only once
isomalloc.c:1526: error: for each function it appears in.)
Fatal Error by charmc in directory 
/usr/local/NAMD_2.7b2_Source_mvapich2-1.4_gcc/charm-6.1.3/mpi-linux-x86_64/tmp

returned error code 1
charmc exiting...
gmake: *** [isomalloc.o] Error 1

Not sure why I am getting this error now and not when I compiled
with the older version of MVAPICH2. I am a bit puzzled as I am using
the same underlying compiler gcc/g++ 3.4.6 in both cases.

Any suggestions what is causing this error and how I can get it 
resolved?

Thank you very much.
