Re: [Boost-users] Query regarding compiling BOOST parallel graph library

nm -D output [pragatheeswaran@prairiefire lib]$ nm -D libboost_mpi.a broadcast.o: nm: broadcast.o: No symbols Yes I am looking at ~/bin/boostpath/lib directory for the specified library files. Thanks, Praga. On Wed, Nov 25, 2009 at 1:00 PM, praga wrote:

I guess you are right.. I have some problems with some basic boost mpi stuffs itself..

I ran a simple program using boost mpi but I found some problems with that. I have given the code and actions I have done. The ldd clearly says it cant find many libraries. I am not sure how to fix this. Could you please help me ?

main.cpp

#include #include #include <iostream>namespace mpi = boost::mpi; int main(int argc, char* argv[]) { mpi::environment env(argc, argv); mpi::communicator world; std::cout << "I am process " << world.rank() << " of " << world.size() << "." << std::endl; return 0;}

Thanks, Praga.

when I did an ls I didnt find any extra files. Could you please let me know where I went wrong?

Do you get the warning about MPI not being found? Does your libboost_mpi.{a,so} contain any symbols (use nm -D on the .so file)? Which lib directory are you looking in? The one in ~/bin/boostpath/lib? I'm just checking the "obvious" things to look for simple problems first.
