Hi Guys,

Anybody been successful with combining Boost.MPI and MPICH2 before?

I keep getting this link-time error about 'now' couldn't be found. The
command I get from Boost.Build + Boost.Jam is the following (stripped
of Friendster-specific names/symbols):

    "g++-4.3.3" -L"/usr/lib64"   -o "output" -Wl,--start-group
"main.o" "boost_1_38_0/bin.v2/libs/mpi/build/gcc-4.3.3/debug/link-static/optimization-speed/threading-multi/libboost_mpi-gcc43-mt-d-1_38.a"
"boost_1_38_0/bin.v2/libs/serialization/build/gcc-4.3.3/debug/link-static/optimization-speed/threading-multi/libboost_serialization-gcc43-mt-d-1_38.a"
 -Wl,-Bstatic  -Wl,-Bdynamic -lmpich -lpthread -lrt -lrt
-Wl,--end-group -g -pthread -O2 -Wl,-rpath -Wl,-z,now -Wl,/usr/lib64
-march=opteron -pipe

The auto-configuration worked for MPI:

===============MPI Auto-configuration===============
Found MPICH wrapper compiler: mpicc
MPI compilation flags: -march=opteron -O2 -pipe -Wl,-z,now

MPI launcher: mpirun -np
====================================================

In my Jamfile I have something like the following:

  exe output : main.cpp : <source>/boost//mpi <library>/mpi//mpi ;

Am I missing anything obvious?

TIA
